Hi guys,
I have bought SIM900A modules. My module details after AT+GSV command are:
SIMCOM_Ltd
SIMCOM_SIM900A
Revision:1137B03SIM900A128_32_SPANSION_TTS
I would like to use them in Europe (Poland). I have tried software called 1137B06SIM900M128 32 SPANSION TTS ITALIAN from this website but Customer flash loader (CFL) says: “ERROR The cla flile doesn not match the Target ..”
I know from CFL v1.8 that my flash details are:
Manufacturer: Spansion
Flash Man ID: 0x01
Flash Dev ID: 0x007E
Flash Ext ID1: 0x0063
Flash Ext ID2: 0x0001
I need firmware for that kind of flash to use in Europe. Has anyone got it?
Greetings

Hello,
I have GSM SIM900 module written on it:
S2-1040S-Z090S
SN: MP0610502102077.
Is it 32Bit or 64bit, how to recognise? What firmware 1137BXXSIM900A(or M or D)32 (or 64)_ST or enhance to use?
Please I need help.
Thanks,
Nesa
Your best bet would be to check the existing firmware version, From that you can know the 32 or 64.
For SIM900 you will use the M prefix. D is for SIM900D. ST is standard firmware and Enhance is the one with DTMF and other extra features. I prefer enhance if available
Hello,
I have GSM SIM900 module with mark:
S2-1040S-Z090S on it. How to determine is it 32 or 64 bit module? I did flashing with
1137B106SIM900M64_ST_ENHANCE firmware. Which firmware should I use …32 or 64 bit?
Thanks,
Nesa
assalamu’alaikum Mr. Dost Muhammad
I have several sim7100c and sim7100ce. As far as I know, sim7100 can support 3G networks on 900MHz and 2100MHz frequencies.But I’m having a little problem, using the same sim card that supports 3G 900Mhz networks, Sim7100C can be registered on a 900Mhz 3G network but sim7100CE can’t.Conversely, using another card that supports the 2100Mhz 3G network, Sim7100CE can be registered at 2100Mhz but Sim7100C cannot.
What/s the solution ?
Thank you very much
hello i have a sim 900 a module v5.1 version im conecting it with TMFT 2.6 i see the hex string(i refer the …) but it is not respondig to any outer comand. sending AT comand nothing. do you have any idea what am i doing wrong?
Are you sending AT followed by the new line character?
Hi,
I have Sim900A for 32 bits firmware. Which version do i need to get Quad band and HTTP functionality?
Sim900A is a Dual-Band 900/ 1800 MHz modem.
Assalam Alaykum Dost
i have both sim 800L and sim 808, working pretty fine with Arduino boards for sms/http protocols BUT i want to drop out external mcu (Arduino) and use internal one – Embedded AT , unluckily i don’t know where to start
i have all the required files , from links above , , demo_examples , i can’t test them because i am stuck..i excel in c programming
if you could direct me what to do like, pasting the demo_examples to IDE , compile it, burn it, hardware connection , etc , would be greatly appreciated .. Thank You
note: simcom refused to offer me a help regarding the issue, they do that to their big clients
sorry for the delay in response.
Please follow the documents in the docs section of the files you got and they are straight forward you don’t require IDE. You will need to use the RVCT_EAT compiler which will be provided in the same package
Is it possible to use SIM900A GPIO to control relays without using external MCU?
Yes, You can utilize EAT (Embedded AT)
hi teeblog, how to write code in gsm900a? how to enable gsm900a gpio pin?
Do you mean Embedded AT?
in sim900a we have arm processor and we have some GPIO Pins right . i have to enable that gpio pins as a intput and output. thqs.
which 32bit firmware supports AT+CIPGSMLOC command in sim900a??
i have 1137B11SIM900A32_ST firmware
at commands:
at
ok
at+sapbr=3,1,”Contype”,”GPRS”
ok
at+sapbr=3,1,”APN”,”WWW” (vodafone)
ok
at+sapbr=1,1
ok
at+sapbr=2,1
it gives ip address
at+cipgsmloc=1,1
error
I am not sure
AT+CIPGSMLOCis supported in SIM900AHi !
Any idea where to get firmware that matches my
SIMCOM_SIM900A; Revision:1137B01SIM900A64_SPANSION_EAT
as after an uneventful (normal) upgrading to register to European network, it kind of “crashed” now only reacting to power on/off and allowing re-trying flashing…
Now, I’ve later learned that my chip has memory by SPANSION, which requires a specific firmware version.
And, that’s what I’m now looking for.
Juha
Your best option would be to contact simcom tech support
Hi,

OK
thank you in advance for your help

i have sim900A and i want to decode DTMF tones but i did not find any firmware for SIM900A to decode DTMF tones.
Did any have firmware for SIM900A that can decode DTMF tone
and can i use SIM900 firmware in SIM900A like this one (SIM900M64_ST_DTMF_JD_MMS)
Thanks
Walaikum assalam brother. I guess the firmware with enhance tag in the name might support DTMF.
Hi thanks for the quick response
In the start i also think the same it might support DTMF decoding but when i try these command its giving me error
AT
OK
AT+DDET?
ERROR
AT+DDET=?
ERROR
AT+DDET=1
ERROR
AT+DDET=2
ERROR
AT+DDET=3
ERROR
i just stuck in my project and i have very few days left i don’t know what to do.
only final solution that i am thing is to test SIM900 firmware in SIM900A
AT_DDET just use to enable DTMF detection.
i think you need to transmit theDTMF code?
to transmite DTMF code you can use AT+VTS=n
that n is Ascii code like as 0~9
i want to decode or detect DTMF not transmit.
DTMF transmission is fine.
Transmission is simple.
AT+VTS=n
where n can be (0-9), #,*,(A-D)
i need to decode DTMF with my SIM900A any help will be appreciated
Thanks
for DTMF detection you must just Enable DTMF detection by using AT+DDET=1
if the module don’t accept it you must upgrade your firmware to ENHANCE version or ST_DTMF_JD_MMS version.
AT+DDET=1 the module don’t accept it
what firmware version should i have to use in SIM900A so the it can accept AT+DDET
thanks
AT+GSV
SIMCOM_Ltd
SIMCOM_SIM900A
Revision:1137B16SIM900A64_ST
This is the current version that is running
.
I did it that to Dost Muhammad And Amir Razavi
i implemented my final solution
installed SIM900 firmware in SIM900A and all DTMF tone detection are fine now.
AT+DDET=1
and receiving all the tones.
from 0-9 *,# did not checked A-D
i will help if any have issue regards to dtmf tone detection using GSM module or without GSM module.
Thanks
HI,
I’m using SIM900A, How to get DTMF tone, In what process you get it,
Anybody suggestions will be appreciated, Thanks.
What do you mean by “get a DTMF tone”?.
During a call if the other party sends a DTMF signal for the key ‘3’ the module will send a URC in the form of
+DTMF: 3What do you mean by “get a DTMF tone”?.
During a call, if the other party sends a DTMF signal for the key ‘3’ the module will send a URC in the form of
+DTMF: 3Hi guys
does any body know about other parameter of AT+DDET command?
AT+DDET=1
>>OK
AT+DDET?
>>+DDET: 1,5,300,0,200,224,0
OK
Thanks
You can refer to an updated AT command manual for that purpose.
Thanks

Hi dear brother
I’m using SIM900 for 4years in a math product(over 5000module) with firmware version : 1137B08SIM900M64_ST_DTMF_JD_MMS
but i founded new problem : the module reset when it received an unsolicited code(+CMT:…..)!!!
At fisrt i tried to discard it by using AT+CNMI=1,0,0,0,0 command but the problem didn’t solved.
I upgraded the firmware to 1137B06SIM900M64_ST_ENHANCE version.
the problem solved and the module didn’t reset but i found new problem.
when i enable the the DTMF detection by using AT+DDET=1 the module didn’t detect DTMF code 4,5 in case of with old version it worked correctly !!!
its very strange . it can detect all DTMF code except +DTMF:4 and +DTMF:5 !!!
I also use AT+SIDET=0,0 to increase the chance but it didn’t work.
please help me.
Thanks alot
I have been using SIM900M64_ST_ENHANCE version as well as SIM900M64_ST_DTMF_JD_MMS version on sim900 and didnt face any problem with the DTMF for key 4 and 5. Can you Try another _Enhance version?
its very strange but really have problem just with key 4 and 5.when i have a call from telephone(Line) there is any problem but when the call is from any mobile cell this problem occur.
I tested with more than 10 module and all of them have this problem.
I think 1137B06SIM900M64_ST_ENHANCE is final version. is there any ENHANCE newer version?
Could you help me please Muhammad?
Is 1137B06SIM900M64_ST_ENHANCE is final version. is there any ENHANCE newer version?
i couldn’t resolve my problem yet about detection of Key 4 and 5 !!!!
There is no such issue with the firmware as such.. Can you share your hardware
I have a sim900A with a 1137B05SIM900A64_ST_ENHANCE and I need to change it for european simcard. I cannot find properly firmaware. What can I do?
This works:
1137B01SIM900M64 ST ENHANCE
Does it support DTMF?
I want to edit the firmware of SIM900 so what are the software i have to download?plse help
I assume you mean updating a firmware… You need an appropriate firmware and the flash uploader software
Hey,
What should I do it if flash uploader shows the message Power Up the target? I tried connecting RESET pin to GND for a while – nothing happened.
Hi Muhammad,
SIM900A module will support https?
Hi Sir,
I need help with +HTTPACTION:0,601,0 problem
My Seedstudio Sim900 board came originally with 1137B13SIM900M64_ST firmware. There was no HTTPS support so I flashed my module with SIMCOM_SIM900
Revision:1137B06SIM900M64_ST_ENHANCE firmware with help from your site. Thank you very much by the way. Now while trying to connect using HTTPS I get the above error (Network error according to command manual). all HTTP requests are successful though when I disable HTTPS. From what I’ve been hearing after searching online for a solution is that this could be a redirect. Others say after putting a bit more credit/data on sim card it works. If the problem is network related why are http requests working? Also when I put the sim card in my phone I can browse https sites. Should I try a different ‘enhance’ firmware or is it a URL problem? When I try to intentionally put a bad URL I get a different error – 603 (DNS Error), which is correct. Can HTTPS work on my phone bowser but not on the sim900 module, or is there a step I’m missing? Please advise.
Status codes above 600 (and some in the 500 range) are unassigned in the HTTP standard. In the AT command manual , status meanings are given in the notes on the HTTPACTION command:
I understand that the error is a network error. Has anyone you know successfully made an HTTPS request using a sim900 module with the firmware mentioned above? I’ve tried different versions and the results are the same. I want to continue trying if it is possible…
Hi Teko,
Can you please share your workout for https if you have got success? I have started working on similar kind of project.

Hello, I am trying to update a SIM 868 from version 1418B01SIM868M32 to 1418B01SIM868M32_BT. I am using the simcom series download tool customer but in the window of the target, does not appear SIM868M…si I cannot update it. Do you know any solution? Thanks!
Nobody?…
Hi Javier; do you know where to download the bluetooth firmware 1418B01SIM868M32_BT
you need to use simcom series download tools customer 1.14
simcom series download tools customer 1.14 is available above now
Hi Dost do you have the firmware files for sim868 bluetooth?
Currently not. Will try to get them and upload here
Got one.. Will upload soon
Hi.
I have SIMCOM 900 Module (S2-1040S-Z1K0K) (Serial #: MP0615112442952).
I am having difficulty to register this modem to a custom-made network (i.e. a BTS).
Also, I need my GSM shield to receive a Cell Broadcast message (CB).
Anyone has any suggestions about preferred firmware that I can install and upload so my modem can register and receive CM message.
Thank you
Hi. I don’t have any experience working with custom BTS
Hi. I bought SIM900 module. I’m trying to send an email with attachment (jpg, bmp files) through SMTP. I receive email but file is corrupted. After few research, I found out that SIM900 automatically adds CR(carriage return) and LF(line feed) to the file. That causes the corruption of file. How I may fix this problem? Is there any AT command to stop this? Please help.
How do you send the email. Can you list the commands you use
Sir, site ignores my reply with list of AT commands. I can’t see my reply.
Dear I could not get you…
Give me your code or commands that you use to send an email please
After AT+SMTPFT command I send binary data to SIM900. I keep sending 1000 bytes, at the end of file I send remaining bytes.
I did everything according to the SIM900 Email manual. I also updated firmware to latest one. I don’t know why SIM900 automatically adds bytes (0x0D and 0x0A) to attachment.
What tool are you using for sending the file in binary format to sim900?
1) “AT+SAPBR=3,1,\”CONTYPE\”,\”GPRS\”\r”
2) “AT+SAPBR=1,1\r”
3) “AT+SAPBR=2,1\r”
Sir, when I try to post my code site refreshes, and my comment disappears. I don’t know why. I took my at commands from SIM900_Email_AT Command Manual_V1.04.pdf.
Comments are moderated so you might not see them until they are approved. If you have a previous comment and it is approved your comment will be approved automatically. I see that you entered the same comment 16 times forcing the site to consider it as a spam attempt.
Sir, I can finally see the list of my AT commands. Please, can you see any mistake in commands? If you see, please tell me. Thank you.
What tool are you using for sending the file in binary format to sim900? Seems to be an issue in that!
I’m using terminal software. They are RealTerm and Advanced Serial Port Terminal. I also pay attention to send data in binary mode.
hi There, I have SIM800L and when I run AT+CGMR I get, Revision:1418B02SIM800L24
I was trying to update to 1308B09SIM800L16 but I get following error https://s16.postimg.org/v60lh265h/ERROR.png

Another question I have it, is there SIM800L EAT firmware available ?
Thank you
L24 AND L16 are not the same hardware variants5
Got it, I didn’t know, what about EAT firmware for L24?
SIM800L doesnt support EAT
Anyone have a working firmware for S2-1040W-Z1K10 or any other 1040W?
Found out that this module uses a 32MB firmware, 1137B08SIM900A32 ST
So anyone have a sim900 32mb version firmware so I can unlock this? have 4 just laying usless waiting….
Try 1137B09SIM900B32_ST
Do you have the firmware file?
Yes I can confirm that 1137B09SIM900B32_ST works and I now have 4 unlocked Sim900A S2-1040W running as unlocked (works in Sweden) 900B units.
Can you please share the firmware as well
Its uploaded now.
Thanks alot
It does work in Brazil
hi friend, i’m trying to learn how to program sim800 how embedded MCU, do you have any experience with this?,
You can start with reading the user guide and application note for Embedded AT for the module you are using
Hi Dost, i have multiple sim800 modules with same Bluetooth Mac Address… any idea if it is a BT firmware bug or really an issue with Sim800 modules????
I haven’t got the same issue. May be its a bug in the firmware.
Does any sim900 32Mb firmware support DTMF decode function?
Thank’s
Hi, does any sim900 32 bit firmware support DTMF?
Thank’s
It should have the tag dtmf or enhance in the firmware name if it supports DTMF
Hi,
In my SIM900A module gives the ERROR message when i run AT+HTTPINIT. Willl it be solve after firmware update. if it is yes which version should i upgrade?
Also my sim900A firmware is
Try to set AT+CMEE=2 and then try again to see the error message
Hi Dost! it is same as previous errors. what should i do? it’s properly work sending SMS. but i need work it’s gprs http
Please give the complete set of commands you are using to get http connected
And thanks Dost for quick response,I refreshed the page several time till to get ur reply 🙂
Ok. Before HTTPINIT try these two commands.
AT+CGATT?
AT+CGREG?
Debug using the following . Its best you restart your modem and then try these…
Hi Dost, I tried debug this code without restarting module. So I tried to restart it couldn’t find the way howto do it. this is the module i’m using.. can u tell me how can I restart it.

Hello Nuwan,
I am facing same problem , can you help me?
sir ,
firstly thank you very much for uploading these firmware versions
and sir i am trying to send a MMS using Sim900A using firmware version 1137B07SIM900A32_ST
but getting error from very first command , every else command and function is working properly
please tell me which firmware should i use for sending MMS.
Thank you
Thanks. Can you please let me know which command it fails
Sir ,I had sent “AT+CMMSINIT” .
I guess your firmware doesn’t support MMS
sir will you please tell me which firmware version should i use
Use any version with _mms or _enhance in the name
sorry sir, but i didn’t see any firmware version with enhance or MMS in its name
and sir mine is 32 type of module so it does not support 64 type firmware versions , so can i use sim 900B or D or Sim 900 for firmwares for my sim900A
32 and 64 shoumd not be compatible.
Sir which firmware should i use there is no firmware of type 32 which has
enhance or MMS in its name.
Hi dear Dost Muhammad Shah ! is it possible to set 300 baudrate for USART? i read datasheet there was wroten minimum baudrate is 1200. please help me if you have any idea(Is this possible to write my own embedded AT( i mean write my own software with RTOS)
You need to select from one of the standard baud rate values.

HI dear Muhammad! I have a problem with SPI on sim900 module. When i compile and download spi sample there is no information on SPI CLK and MOSI pins(i chekced with oscilloscope). i’m using 1137B02V01SIM900M64_ST_DTMF_JD_EAT.cla firmware. Please help! i have spent two weeks on it without result( sorry for my poor english).Thank you
Can you share how you initialize and use spi ?
//Initialization
ebdat5_21EnhanceSpiConfigure(SSI_SLAVE0,SSI_3WIRE,SSI_SYSTEM_DIV_64,SSI_FALLING_EDGE,SSI_MSBFIRST);
//Write byte
ebdat5_22EnhanceSpiWriteByte( SSI_SLAVE0, 0x30);
Have you followed the SPI example in the EAT for sim900?
yes of course i compiled and flashed both spi and spiEnhance examples but there is no result?
Thank you i solve the problem with change sim900 module to other one! And know everyting is ok
glad to know it finally worked for you…
i want to know how can i update my whitelist in sim900a gsm module , where my contacts are saved
Hello Dost, I’d like to ask you an advice on a SIM800C module. The CIPGSMLOC command gives me a well defined position (even too defined since it’s stable at the 6th decimal number), almost 1000Km far away from where I’m transmitting. In the examples I found over the net I see always position around Paris, like the one I get (+CIPGSMLOC: 0,2.333626,48.802647,2016/07/29,10:52:14). The version revision is 1418B02SIM800C32_BT_EAT_115200. Even more, I’m getting almost the same position with a Sim928A (CIPGSMLOC: 0,2.326602,48.803823,2016/07/29,10:13:12 , firmware revision 1137B01SIM928A64_ST_ENHANCE). Need FW update? Thank you
easier than easy…poor GPRS signal…
the position will depend on the signal strength and number of antenna’s available. It will be near accurate where the signals are good and you have access to 2+ transmitters available…
I have used SIM 900A GSM Module , I connect GSM module with my pc and verify all l AT command working fine check on PC Hyperteminal.
Now I have insert Vodafone sim card in SIM900 device. I send ATD commad to SIM900 module and it call to relative netowork. after 60 second some response like “NO ANSWER” or “NO CARRIER” or “BUSY” get on Hypertemianl. can i change that response using AT command?
if yes thensuggest us.
I need below response for my application in any network
GSM Modem dial call to user then
1) if User Pick call then respnse should be “CONNECT”
2) if User disconnect call then response should be “BUSY”
3) if User not pick call then response should be “NO ANSWER”
4) if user mobile phone in switchoff mode or airplan mode then response should be “NO CARRIER”
If you need to know if the user picked the call You should set
AT+MORING=1This will let you know if the other side is ringing or call is answered.If the user Hangs the call you get BUSY by default. may be your provider is not sending the busy code. Try with another simcard.
When SIM900 GSM module dial call to user then if User Disconnect call or Not Pick call or Switchoff mode then SIM 900 display “NO ANSWER” response. SIM 900 Module not give response accroding to condition. so my application not get exact idea user pick call or disconenct call or switchoff mode.
Note : Right now i have insert Vodafone SIM card into SIM900 GSM Module and USER mobile Service provider is Reliance and Telenor.
Hello Dost
I have flashed my sim900 shield with rev.1137B08SIM900M64_ST_DTMF_JD_MMS
DTMF tones are working now but I cannot pass the parameters to set the tone duration.
Setting the AT+VTD command has no effect, tone duration is always the same,
When I pass the duration parameter to AT+VTS I get error back.
In sim900 manual 1.1 there is a parameter for duration
AT+VTS=?
+VTS: (0-9,*,#,A,B,C,D),,(1-255)
OK
when I try AT+VTS=”1″ I hear the tone at the remote.
when I try AT+VTS=1″,100
AT+VTS=”1″,,100 I get ERROR
Having the same problem with AT+CLDTMF command, duration cannot be set.
I need to build up a contact-ID protocol time line but without setting the tone duration it is impossible.
A I using the correct firmware?
Any help is appreciated.
in sim900
AT+VTDis used to set duration of DTMF commandI already tried that, setting duration with AT+VTD has no effect.
The duration is always the same.
It should have worked. There are no issues with firmware I think. I would suggest contacting a FAE (field application engr) from simcom or simcom’s supplier in your region
Hi, I have flashed several S2-1040V units (sim 900A) but got a shipment of 3 new ones, didnt look so closly so flashed them all 3 as usual… But now they wount boot. They where S2-1040W-Z1K10 (I think its the W that is the diffrence).
Anyone have a working firmwire for them? I have tried to flash everything from this site…. Nothing works. The board just sits and rebots itself every second. (same wire with a 1040V works).

Hello Dost. I am not able to get BT working on my SIM800 module. When I query AT+GSV I get following response:
SIMCOM_Ltd.
SMCOM_SM800
Rev: 1308B02SIM800M64_BT
This possibly means that BT firmware is loaded? If not, which file can I use from your firmware collection? Can you please advise how I can get BT to work? All BT related AT commands give “ERROR”.
Thanks
Bluetooth should work with this firmware
I tried AT+BTSTATUS=? and AT+BTPOWER=1 but in both cases I get ERROR as the response. My SIM800 module is made in India and is standard with PWR and RESET buttons, RING and PWR LEDs, etc. Basically I cannot get the bluetooth enabled. GSM works very well.
I am using a small 12 V DC power adapter giving about 500mA.
Please help.
Hi Dost Muhammad:
I work for an Utility in Costa Rica. We have a GSM Shield for Arduino, It has an SIM900 chip, and it’s firmware is 1137B15SIM900M64ST. In the web page of SIMCOMM2M, the SIM900 supports FOTA feature, but I was wondering if it’s necesary to change the Firmware to enable the FOTA feature. I saw in your webpage the firmware 1137B01SIM900M64 ST DTMF JD MMS FOTA.
Best regards.
Luis.
I guess you need to change it as far as I understand but I am not 100% sure.
I have SIM900A gsm modem, working perfectly for call and SMS. I wanted to use DTMF from it. But to enable dtmf, when i sent command “AT+DDTE=1” , then the modem sends the reply as “error”, So i thought to update the firmware.My firmware version was 1137B12SIM900A64_ST.rar . So i updated the latest firmware as 1137B03SIM900A64_ST_ENHANCE. And flashed it successfully I CANNOT SET BAUD RATE BACK USED AT\r
command no respone any help?
Search this blog for autobaud… Once the modem powers on send AT\r a few times until you get ok
sir i tired AT\r
no use re flashed frimware no use any altrenative?
SIR
IT WORKED FOR WHEN I REFLASHED WITH 1137B03SIM900A32_ST
BUT SAME AT+DDTE=1 ERORR REPLY
FIRMWARE FOR FLASH SIM900A TO USE DTMF COMMAND
what is the difference between 1137B03SIM900A32_ST and 1137B03SIM900A64_ST_ENHANCE 64 st is nnot working on my sim900a
1137B03SIM900A32_ST is for Sim900A with 32MB of Flash
1137B03SIM900A64_ST_ENHANCE is for SIM900A with 64MB of Flash
The problem here is you have a 32M version of Sim900A for which the new firmwares are not available.
Do you have firmware for SIM800W or SIM840W ? Can you send it for me? Thanks alot
Well I don’t have them at hand. Will try to get them and let you know 🙂
Thank you very much
Hi! I have a sim800 module and am trying to use its bluetooth capabilities.
But any such bluetooth commands like “AT+BTHOST=?” is giving me an error response, so I’m assuming the firmware that’s preloaded doesn’t support bluetooth functionality.
I have come across 1308B08SIM800M32 firmware, but how do I load this firmware?Any tool that may aid me in uploading the firmware?
use the firmware with _BT tag in name.
Thanks for the quick response!
will try it out and could you recommend me a tool like the ” sim900 Customer flash loader V1.01″ for the sim800 module which i can use to upload the firmware.
You can get it in the Sim800 eat IP file
I have a SIM800L that will not provide any response to AT commands. I know the SIM800L is getting the commands via viewing signals on an oscilloscope on the unit’s RX pin (also the unit will shut down when sending a “AT+CPOWD=1” command. On the TX pin, nothing is ever transmitted back. Is there something wrong with this chip or has the software become corrupted?
Try to reflash firmware.
Thanks you for your quick response… could you please provide me with a link for how to reflash firmware for a SIM800L?
I downloaded the SimCom SIM800H EAT flash tool (since I didn’t see a flash tool for the Sim800L)… I unzipped the files and ran the “SIMCOM_SIM800H_EAT_flash_Tool.exe. I changed the comm port to the appropriate comm and then loaded the .CFG file associated with the SIM800L (1308B09SIM800L15.cfg)… the program than showed four files “ARM_BL”, “ARM_EXT_BL”, “PRIMARY_MAUI”, “VIVA”. Not having any instruction, I checked them all and clicked “Download”. The flash tool does nothing… just sits there at 0% (no files loaded to my SIM). Do you have any ideas as to what I’m doing wrong?… again, are you aware of any instructions on how to use this tool? Any help would be greatly appreciated. 🙂
hi TEEBLOG
i have a problem with conecction to network, i have a GPRS shield (DUINOPEAK) and have a SIM900A but i insert the SIM and try to call and responses “NO CARRIED” and the signal is “0,0”
I suppose that is because unable to connect to network. I’m from Mexico
I try to load de firmware of SIM900 and SIM900A and it doesn’t work
Could you help me please?
Regards, MARCO
As you said the reason is that the module is locked to certain operators. There are people who flashed sim900 firmware to solve their issue. Can you let me know which firmware did you try
Yes, I try load different firmware of SIM900 (like: 1137B06SIM900M64_ST_ENHANCE or 1137B12SIM900M64_ST) and does not work

What can i do to repair this?
Make sure that PWRKEY pin is kept on ground during initial stages of flashing firmware
Just want to ask. I have problem with SIM900A.
I have reply when I type AT+GSV:

You can change the port number in devicemanager. Google how to change port number of com port in windows
I am currently working on SIM7100E. I am unable to initialize it. I can not sent the AT commands to it. Can you please help me with the initialization of the module?

Is the modem switching on and registering to network??
I got through that. Thanks. But now the problem is that i do not know how to register to the network and in what sequence is should apply the commands to use it for GPRS and 4G. Please help me with that.
Thanks
You should follow the application notes provided for your module
The application notes are not much detailed. They have just grouped together the commands in any random order and compiled them into application notes. So I am unable to take any help from them.
Hi TEEBLOG.
I am using a SIM800L and it fails to register to the Vodafone UK network when using the AT+COPS=1,0,”vodafone” command.
Is it possible the firmware version Rev: 1308B08SIM800L16 is locked to networks other than UK?
Also if I try to reflash the SIM800L can I use the 1308B09SIM800L16 firmware? and do I use the SIM900 Flasj loader to do so?
Hello, I try to ground pin16 NRESET, it s the same…
Hello,
Thanks for your page!
I have got a SIM900a module (ATK Sim900a V15).
I am living in Europe so I want to change firmware using sim900 customer flash loader 1.01 or 1.9.
The connection with arduino Uno is good: this is the answer for “AT+GSV?”
SIMCOM_Ltd
SIMCOM_SIM900A
Revision:1137B13SIM900A64
My problem is that when i try to connect with customer flash loader, the protocol is looked at the initialisation.
I try to power only ( no pwrkey so no blink led). Bauds are fixed to 19200 in the arduino software and on the Sim application…I dont understand please help me.
Can you share image or link to your sim900A module/sheild?
Hello, Thank for your interrest.
Thé board is here http://store.roboticsbd.com/home/144-atk-sim900a-gsm-gprs-module-bangladesh.html
Know, i Wonder if thé chipset of usb CH340 Could be thé problem. I look with native port of an arduino due, it is thé same !
But i see synchronisation bits of the application, maybe my system is too slow ?
I am buying à ft232 TTL convertisor so it is possible to have an auto baudrate.
Parraps thé arduino program will be better if pin Rx Serialsoftware will exactly correspond with pin Rx usb usine minimum of lines and not using
Whyle(Myserial.avaible ()){serial.print(Serial. Read ());} ? What do you think, want and see ft232 ? Or have you got an idea with arduino s?
Hello, evrithing is OK. So arduino serial usb chips CH340 is to bad to communicate with SIM900. If connection is OK with arduino but, If nothings append when you are trying to connect and upload firmware, with customer flash loader (using the Arduino as converter) (all versions flash loader) Buy an FT232 serial converter, instead of arduino, and evrithing is OK. Thank!
That’s good news!

Hello Dost,
Last time I had the problem and your comments helped me alot. I’m using SIM900A in Serbia and I couldnt start it with firmware for sim900a so I flashed it with sim900 firmware and it worked. At that time I just needed SMS and calls but now I need GPRS and HTTP and I think I have the same problem that this module can’t do GPRS in Serbia. Can you tell me how can I check this? This is my log:
AT+GSV
SIMCOM_Ltd
SIMCOM_SIM900
Revision:1137B06SIM900M64_ST_ENHANCE
OK
AT+CGATT?
+CGATT: 1

AT+CREG?
+CREG: 0,1
OK
AT+SAPBR=3,1,”Contype”,”GPRS”
ERROR
AT+COPS?
+COPS: 0,0,”Vip SRB ”
OK
Just to say that I’m solved the problem. It was stupid thing but maybe it will be useful to someone. I use Putty and It happens that whenever I pressed quotes i was getting two quotes like this “”, and I always erased one of them and continuing to write the command. But if copy the whole command and paste it it works. I forgot that characters are sent not only when press enter but after every character pressed. Thank you anyway…
Thank you for your reply, here is the log:
Please show How you are establishing the connection?
I’m establishing connection through rs232 USB to serial adapter directly to PC. I’m using Putty to send AT commands. This SIM card works correctly in cell phone. AT+CPIN command is already listed in the log. Thank you very much!
+CPIN: PH-NET PIN means that the modem is locked to certain networks. Can you give the exact model number of your module?
It is S2-1040V-Z096X
S/N:MP0615142143161
IMEI:866762024258392
Thanks
OK , So its SIM900A that is restricted to a few countries. May I know where are you using it and the network you are using! Please check this comment as well
I flashed with 1137B12SIM900MST and for now is WORKING OK! Thank you!
I’m using it in Serbia
SIM900A should not work in SERBIA until it i somehow unlocked. 1137B12SIM900MST is for sim900. You might get some issues but it should be fine over all
i am using the same board,s2-1040v-z096x, s/n:mp0615222364212.it working well with terminal software but when i interface it with arduino its not giving response.please suggest me what to do…its very very urgent my project deadline is on 16 aug.please replay me on time..my email id is yrajkishor19@gmail.com
share your connections
AT+CPIN?
Verify a SIM is correctly inserted and power cycle the device.
This means the SIM/device is locked.
If you can use the same SIM in different devices without the entry of a lock code and they operate normally you need to verify you have ordered the correct Multi-Tech product.
Hi, I am trying to download an app for sim808 EAT, and it seems that I can’t figure out the begin address for the skatter file for the EAT app. Do you know where can I find description for the address usage in the skatter file?
Thanks for the help
you should be selecting the starting address as 0400000 if you just want to update the app. Dont forget to select Normal from the drop-down and select Erase source code only option

Hello, I have SIM900A mini ver 3.8.2 with 1137B03SIM900A64_ST_ENHANCE firmware, and I cannot connect to the network. What do you suggest to do? Thank you in advance
When you say
There can be many reasons ranging from you didn’t put a simcard all the way to problems in network or your commands. Please give a log of your AT commands and responses and I would love to help out if I could!
Hell, any idea for a french SIM900 firmware ?
I haven’t came across anything like that yet.
Does it exist??
Hi, I have SIM900 module. I’ve downloaded the firmware version 1137B13SIM900M64 ST with Normal Mode (Core file). Download process is successful. But I power up my module every ~30 s the module send 0x49 0x49 0x49 0x49 0xff 0xff 0xff 0xff. After send that character my configuration is gone. Can you help me to fix it? Thanks in advance.
after an update the baud rate should be set to auto , you need to send
AT\rand it should adapt the baudrate.Hi, send AT\r is ok. but every ~30 s the module send character 0x49 0x49 0x49 0x49 0xff 0xff 0xff 0xff(Periodicly).
I suspect the firmware revision didn’t match.
Do you have the firmware with revision 1137B03T900M64_ST?
Thanks.
if you have sim900 try the latest firmware with ENHANCE TAG in firmware name, Try this One http://dmsherazi.com/wp-content/uploads/SIMCOM/sim900/1137B03SIM900M64_ST_ENHANCE%20%281%29.cla
I’ve tried for this revision. the result is still did not work as well(every ~30 s send the character0x49 0x49 0x49 0x49 0xff 0xff 0xff 0xff ). I think any different between SIM900 and T900. so I cannot use the firmware revision for SIM900 in T900. If you have the firmware revision for T900 or the specific revision is 1137B03T900M64_ST, please share. I really need that. Thanks. 🙂
Hello,
I am trying to use a SIM800L in France but it doesn’t work with ATcommands.
I thought maybe I need to upgrade the firmware. Do you have any tutoria to do it?
Thanks
Can you please explain what do you mean by doesn’t work with AT commands??
May become there is an issue with your baud rate or connection
I try followin At commands:
AT+COPS=?
->+COPS: (2,”Orange F”,”Orange”,”20801″),(3,”BOUYGUES TELECOM”,”BYTEL”,”20820″),(3,”SFR”,”sFR”,”20810″),,(0-4),(0-2)
AT+COPS?
->+COPS: 1
AT+COPS=0
->+CME ERROR: 604
AT+CSQ
->+CSQ: 14,0
AT+CREG?
->+CREG: 0,3
Normally it is supposed to connect on “Orange F”.
Do you have an idea of this error?
I can test other AT commands if you want.
Thanks.
Sim800L is produced for Chinese market and that might be the issue.
But I work with it …its firstly working very well …then the sim doesn’t register to the jordan network
Hello,
I have sim800 with the firmware 1308B02SIM800M64 so it does not support Bluetooth. So if you have can you please upload the firmware to support Bluetooth.
1308B08SIM800M32 is available on my other post HERE
Will M32_BT be supported by SIM800 modem or I will need M64_BT only?
Give it a try
Hello:
I have order a SIM900A to chinese provider, I have read now that these versions are locked for Asia countries, but may unlock with new firmware.

Thanks and best of luck. Let me know if I can help at any stage!
great job, do you have any link to firmware upgrades to sim800. I’m having problems with bluetooth together with USSD messages. Bluetooth works with one firmware, and USSD works with another firmware.
I will check and let you know if I have one.
Thank you a lot, I can send the ones I have to you for your list.

Try sending AT with at the start. Make sure that you use AT in CAPS
hi I have troubles with my sim900a it doesn´t work propertly i think is blocked, i´m from Mexico and i hope there is a chance to make it works.
Thanks 🙂
check this comment please http://dmsherazi.com/sim900-firmware-update-tutorials-appnotes/#comment-209
Hi Miguel ! you solved the problem ? I’m in Mexico too, after flash with SIM900 firmware I can’t registered on the network
Hi Dost.
I recently flashed my working SIM900 with SIM900 firmware containing _ST_MMS.
The upgrade was successful.
But after the Update the Module is not registering on the network.
What do you think is the problem, because earlier it would automatically register on power On.
Thanks
does the NET-Light led blink fast?
I am having the same issue…. yes network led is blinking at fast rate.
Hi,
I used 1137B03SIM900M64_ST_ENHA…CE (1).cla, I also tied the pwrkey to gnd.
But this version of firmware is not getting loaded.
The loaded always ends with
Err 070 – Error during acknowledgmetn waiting
Err 070 – Error during download application in flash
I am using Windows XP and have tried other firmware available on internet for sim900.

Hi,
I am using a SIM900 with arduino Uno and I have a problem. Each time I turn the GSM module off, all settings are lost and thus I must first use AT commands for setup and only after that I can use the GSM function with arduino (but sometimes it does not work…). Any solution to use the GSM sketch “easily” ? Every time I start, the CSTT is CMNET and not the one I configured.
Best regards,
Raph
you need to enter the GPRS settings each time if you use
AT+CSTTcommand. Try usingAT+SAPBRand related commands to save the GPRS profilesHi,
I have sim900a module with airtel sim. i have been trying relentlessly to connect to https://thingspeak to update my channel but no luck. i have gone through the HTTPS document for Sim900A and am following the instructions. it keeps on throwing 601(Network error). but if i disable HTTPS(at+httpsssl=0) and try updating my channel through the regular url it works just fine. could you please point me to the right direction to get HTTPS working.
secondly as the document states, the procedure to initiate the HTTPS con, i see that setting the CID doesn’t work till i pass AT+HTTPINIT which i think is command from HTTP and not HTTPS. so if i mix and match both commands, the module responds to https but no update on my channel, 601 error.
thanks bhaijaan.
Hi, Can you please share your workout if you have got a success? I am working on similar project. Your help will be appreciable.
Hi, I’m very new to this , actually I have just modified my first pcb, the one I’m using is for a IDS alarm system called the XSMS for IDS alarm, I had to make some mods for it to work without the interface of the alarm but all is working, I want to know how do I know what is the newest firmware for my unit my firmware is SIMCOM_Ltd SIMCOM_SIM900 Revision:1137B11SIM900M64_ST when AT+GSV is used, which one can I use, also does this units only support GPRS or does it support EDGE and 3G, how do I check. thank you in advance for your replays.
1137B11SIM900M64_ST is an older one , but should work fine.. newer ones come with
ENHANCEtag. There is no public official source to get the latest firmware.Sim900 will support GPRS and EDGE but not 3G.
Hello Muhammad,
I found your website when I was searching for my problem with Sim900 CIT 03 .I ‘ve wondered totally with your site.
I have bought a SIM900 CIT 03 from china for upgrading SIM900. It dose upgrade, but I can not connect to it via hyper terminal to check module.
i dont understand the problem. I ‘ve connected CIT through main port via a USB to serial converter to my PC (it is known as COM3)
In hyper terminal I select COM3 and set baud to 115200 , when I try to connect to module on CIT I just see IIII when I turn on the module but when I type AT nothing happen.Can you guide me, please ?
thanks
make sure you enter
ATcommand in CAPS with\ra few times.HELLO
I’ve done so , but it dosen’t type nothing.also I have sim900 EVB it work properly with hyper terminal.
Hi, After you upgrade the firmware SIM900 is set to auto baud mode,
Can you please make a call to the modem and see what you receive on the terminal?
Hi, I have already change the firmware in a lot of SIM900A (64BIT) with 1137B01SIM900M64_ST_ENHANCE and after that works very well here in Italy.
Now I have others sim900a buyed in China with this strange firmware: 1137B03SIM900A128_32_SPANSION_TTS and the simcom firmware program flasher don’t flash them, I have tried also this: 1137B09SIM900B32_ST but the program says that is impossible flash that firmware on that chip.
Do you now why?
Thank’s a lot
TTSis for Text to speech, apart from this I am unaware of what this firmware has.Try to contact the seller or Simcom Support. liujun@sim.com or xiujuan.yu@sim.com
EDIT
I just came across this table, it shows that the term
SPANSIONrefres to the type of MEMORY.Here is the document
Thank’s a lot, now maybe I understand, this is a new TTS version then with 128 Mb of memory.
I think I try to load the TTS firmware for sim900, do you know where I could find it?
I looked on the internet but I did not find it …
Try to contact simcom directly

Hello, do you have any news about EAT on sim808?
At the moment, No.
I will try to get and post it soon!
Hello!
I’m a beginner with the SIM808 and I look forward to test the EAT. I found today this http://microchip.ua/simcom/ which gives all the information and the tools to download software to the SIM808. I haven’t tried this yet but it’s the only information I found about the EAT on SIM808.
I can try to run the demos and the download tool on the SIM808 and let you know how it went.

Dear Dost:
I just updated the firmware of my SIM900 module (1137B01SIM900M64_ST_DTMF_JD_MMS_FOTA.cla) Everything happened well, but after that:
1) I get no response to any AT command (tried ATr at several baud rates, 9600 and 115200 included)
2) The intermitent LED to signal the connection status, is completely OFF, not flasshing at all.
I am out of ideas at this point. What do you think I shuld try now?
Try re flashing the firmware or any other firmware.
The NET_LED should blink once you switched on the modem using PWRKEY (by providing a pulse, or connecting to GND).
Hi:
I recently purchased the next module:
“New SIM900A V4.0 Extension Kit Wireless GSM GPRS Module Board.”
The problem is that not detected network.
to enter: AT + CREG? Responds + CREG: 0.0
I tried to load different firmware but I still not detect network.
Can anyone tell me the firmware of Europe Spain to SIM900A V4.0?
thanks
Sm900A is intended for China and some asian countries only so it is carrier locked. There are ways to unlock it … please check this reply http://dmsherazi.com/sim900-firmware-update-tutorials-appnotes/#comment-209
Thanks Muhammad Shah
I loaded the firmware indicated (1137b03sim900m64_st_enhance), but my sim900a can not connect to the network.

Hi , can you please tell me how to interface GSM modem to DTMF IC .
my application is it if i make a call to modem and press any key in my mobile it will detect my the GSM+DTMF module. please help me
Which Modem are you using? depending on modem you are using, you may not even need an external IC for DTMF. SIM900 and other modems have built in support for DTMF decoding!
Hello Dost, Thanks for your reply.
I am using SIM 900 modem. How can we decode the DTMF tone using SIM900 modem. We have any digital pin for SIM900 like MT8870. Or else we have to use any commands to decode the DTMF Tones. My application like IVRS system, 1st we have to make a call to SIM900 modem from any mobile phone, depending on key press, 3 phase motor will control .
You need to have a firmware that supports DTMF. To check if your firmware supports
DTMF Send AT+DDET=1If your receiveOKyour firmware supports DTMF.Now if you are in a call and the other party presses any key you would receive
+DTMF:xwhere x is the key pressed.CHECK THIS DOCUMENT AS WELL
Hello Dost,
Thanks for your reply.
I will check this once. I read the PDF, its seam very easy, we need not to add any DTMF decoder.
Yes. I have been using the feature since a few years now.
Hello Dost,
as per your reply, I checked it in my GSM Modem(sim 900).

please do the needful.
I have SIM900A gsm modem, working perfectly for call and SMS. I wanted to use DTMF from it. But to enable dtmf, when i sent command “AT+DDTE=1” , then the modem sends the reply as “error”, So i thought to update the firmware.My firmware version was 1137B12SIM900A64_ST.rar . So i updated the latest firmware as 1137B03SIM900A64_ST_ENHANCE. And flashed it successfully, and made 9600 baudrate back and all. The tried sending “AT+DDTE=1” and it sent reply as “1”. Means DTMF was enabled, Then i tested sending and receiving DTMF tones, it was completely working.
But when today morning i set back to work, it doesnt work. It again shows the same reply “error” when i tried to enable dtmf. I checked the current firmware, it is still the latest one i flashed.
Anyone can help me? please? i stuck very badly. I already made program also for DTMF, but now just unable to just enable dtmf. 🙁 And it was working yesterday but now from today. whats the solution.
You need to send
AT+DDET=1, the reply should beOKAre other functions working correctly even now?
try reflashing the firmware … that might help ?

Sim900 Supports 1.8V and 3V simcards. Please check the product specifications
Hi guys, nice blog, i have questions how i can find sim800h firmware and EAT sum documentation
Your best bet is to contact SIMCOM agent or supplier.
I have a few firmwares on github
Can you please provide any SIM900 32 bit firmware, i dont find any 32bit firmware in the list you have shared.
This is really very helpful post Dost shah, i was working with the china sim900a module “http://fr.aliexpress.com/item/Free-shipping-GSM-module-SIM900A-whole-network-smallest-GPRS-phone-communications-IPEX-message-board-seat/2026788175.html” and destroying one module i figured its firmware number 1137B05SIM900A32_ST, i managed to change baud rate to 19200, not it is responding to AT commands, but when is use at+cmgs, it enters into msg mode and never comes out without showing error when i use 0x1a, i have tried to send msg using arduino but still no out, can u plz help me in solving this issue why is it showing error while geting out of msg,
also i have tried later 32bit firmware, these updates leaves this module into restarting loop every 2 seconds.
Thanx in advance
Once you flash a firmware, send
ATra few times it should reply OK.This Link might help
It send ERROR when i send ATr
One more thing the ATD comand returns
NO CARRIER, and , CFUN: 1CPIN: READY
and when i wanted to send the msg, the msg never send because its not detecting
ctrl+z, or1Amy AT+CPIN? returns , CPIN: PH-NET PIN
AT+CREG? returns, +CREG: 0,0
what does that means? and what should i do ?
Hi,
Where are you using this module?
The SIM900A model is for the Chinese market and some other Asian countries…From documentation of sim900A
There are people who used Sim900A in other regions by Flashing SIM900 (not SIM900A) firmware.. Try it!
So AVOID the SIM900A model unless you are in one of these countries !
I juts found this blog post where the author manages to upload Sim900A firmware and it starts working.
Here is the link for 1137B11SIM900A32_ST.rar
What is the lastest firmware version of SIM900? Thanks (:
The latest one i guess is 1137b04sim900m64_st_enhance, I have the 1137b03sim900m64_st_enhance http://dmsherazi.com/latest-enhance-firmware-for-simcom-sim900-module-1137b03sim900m64_st_enhance/
Hi Dost shah,
I am using a sim900a to connect it to the GSM network. I have put the nodule on a board with required supply voltage and connections to sim card holder. I have also connected LEDs through resistors for status and net.
After powering ON , and pulling the powerkey to gnd the net led continuously blinks and status led is off.
Can you please help me with a solution?
Does this require a firmware update. I am not sure about the current firmware version as tx RX are not connected.
Thanks in advance
It would be easier for me If you share your schematic. Any how the net led should blink, if it blinks that means your modem has switched on.
If it is able to register to the network it will blink slowly. If its not registered it will blink fast.
The status led circuit may be wrong if it still is off
Hello, im working on sim900A, & i want to send mms , can u plz tell me, do i need to upgrade firmware?
My current version is 1137B10SIM900A64_ST
Reply ASAP
Hi , i guess you need to upgrade to enhance version for that.
One last problem I am facing is that AT+CMMSINIT is giving error.
Googling even doen’t provided the satisfactory answer. I fear if anybody would have successfully sent the MMS through SIM900A module.
I am executing following set of commands….
Waiting for your reply !!
Sorry but AT+CMMSSEND is giving the error not the command AT+CMMSINIT as I mistakenly written in my previous post
I have SIM900A GSM module. Currently it has 1137B12SIM900A64_ST firmware and I want to upgrade it to
1137B13SIM900A64_ST_DL. Right now I am using arduino duemilanove. Rx (GSM)–> Rx(arduino) and Tx–>Tx. I have also removed Atmega328 chip.
But I am getting :error during baud rate change
Check Target setting…
Please advice who so ever have done it successfully..
Rx should connect to tx of module and vice verca
I already tried it but then, it doesn’t even download the flash in the RAM. The screen shows “Please power up the target”.
But if I connect Tx–>Tx, then it downloads the flash in RAM but then gives error of baud rate change !!
Please help
Some tips.
Use default baud rate
Keep the pwrkey pin low during the process.
I have tried all the baud rates.
In my GSM module pwrkey pin is permanently grounded…
great, It worked Thanks a lot your blog and prompt replies…
I personally recommand not to use any arduino board but use FT232 breakout boards. I used this board http://www.nex-robotics.com/products/wireless-devices/xbee-usb-wireless-module.html
Connect pin2 (Rx) — > (Tx) GSM Module and pin 3 to Rx of GSM Module.
It worked flawlessly for me. I successfully uploded “1137B13SIM900A64_ST_DL” firmware
But still AT+CMMSINIT command is not working ??
Is their any firmware which supports email or mms for SIM900A as it is available for SIM900.
Waiting for your reply sir !!
Good to know that you got it done.
Use enhanced firmwares.
I am trying to program SIM900 using SIM900DEVIDE. I am using RVCT COmpiler. I am facing trouble in compiling sample Programs given by SIMCOM.. Some programs get compiled and make the .CLA File.. But programs which use sprintf function I am getting Error in loading ARM Libraries…
Has anyone used the Embedded programs in SIM900.. My application is : On getting RING the Modem should Pick up i.e. give ATA command. Then it should Play a file “WELCOME.AMR”.After that It should wait for DTMF Digits o be dialled.. If It gets # ( “DTMF:#”) then the SIM900 should give 1 to GPIO12. Again it should go on expecting a DTMF Tone..If It gets * ( “DTMF:*”) then the SIM900 should give 0 to GPIO12.
I have used a Microcontroller and programmed for this application using AT Commands they work fine.. But I understand the SIM900 has sufficient power to execute a program like this internally.. Can anyone who has worked on this.. Help…
Thanks
I havent used embedded AT.
Hi. I am working on a project to send data to the server using SIM900D. I am trying to initiate HTTP GET request to send the data. The problem I am facing is with the response of the GET request. When I use AT+HTTPREAD, the code hangs there and reading the response never ends and it stays in the while loop that is reading the response, and thats why I am unable to initiate second GET request. I am wondering whether the problem is from the server side? Is it sending the correct response after receiving a GET request? How to check that? Why am I unable to read the response? I need help. Thanks
It appears to be because of the huge code of the page that is returned
That might be a reason. Is there any way that we can ignore the response broadcast? I tried to skip reading it and exluded AT+HTTPREAD command, but still was unable to send second GET request. I think the module gets busy with the response even if we don’t read it. I am stuck here.
If you don’t read the response it should be ok.
Even if I dont read the response, it doesn’t send the second GET request. SIM900D replies with +HTTPACTION:0,200 but the request is not received on the server. Only the first request is received
I have read the Document SIM900 Embedded AT Application Note in which they have given the API’s and detailed Description. I also Got RVCT_EAT Compiler and SIm900DEVIDE program which is required for SIM900 embedded AT Compiling. I have made a New Project and copied Files from the SAMPLEs and tried to Compile but it is giving me Errors regarding >MAP file Empty Execution region description for region HEEP_RAM_DATA ( besides several Warnings. Presently I am not bothering about Warnings. ). Because of the Error the .CLA file is not created…
Has anyone worked on the Embedded AT.. Why this error is coming..
Please Help.
Could you please point me out the links to the RVCT_EAT Compiler and SIm900DEVIDE program, all I am finding is user manuals. I am looking to work on embedded AT as well.
Could you please point me out the links to the RVCT_EAT Compiler and SimDEVIDE program, all I am finding is user manuals. I am looking to work on embedded AT as well. And a quick question will the SimDevIDE program works for other modes as well ? e.g. SIM868, SIM808 etc.
You can find them in the firmware with EAT. Some of the zip files will have all the files. Check 800H_EAT or 800EAT files.
Hi Dost Shah
I have problems flashing my SIM900A. I have this board http://www.uctronics.com/download/SIM900A_Pinout_diagram.jpg. I am using Linux with Wine and flash loader V1.01. I’ve tried to use both reguar TXD/RXD and also DBG_RXD and DBG_TXD. I am using FDTI232 cable.
Flash loader fails after erasing flash memory. Last messages are:
…
Any advice?
Thanks in advance!
Hi, try keeping the powerkey pin low during the process.
Thanks, but it hasn’t helped. I’ve connected pin 0 to GND and got the same results. I’ll appreciate any other hints.
I’ve succeeded with WindowsXP running in VirtualBox. FT232 must be mapped as USB device, not as serial port.
Can you try windows compatibility options and let us know the results.
Thanks for sharing
Firstly, all the information you have put is really useful. Thanks.
I wanted to know, what is the difference between 1137B02SIM900M64_ST_ENHANCE and 1137B02SIM900M64_ST_ENHANCE-EAT? Also, where can I find SIM900 AT command set v 1.08?
Which is the latest firmware for SIM900 which has even the GPS related commands?
Eat versions support adding your code to run on sim900 processor. There is no Gps on sim900. Although you can use data from towers to triangulate position which isn’t accurate. All enhance firmwares support this feature
http://www.mt-system.ru/sites/default/files/sim900_embedded_at_application_note_v1.01.pdf
Furt of all, all the informatio you have put is really useful. Thanks.

Hello,
I am working in a project that uses a SIM900 module to control a system with commands sent via DTMF. I am having a problem with the DTMF decoding. When I use an android mobile phone to control the system it “almost” works. The problem is that some of the DTMF tones are not detected (30 to 40 percent of the tones are not detected). If I use a fixed phone all the DTMF codes are detected and decoded correctly.
Any idea about how to fix the problem?
Thank you in advance and best regards,
Antonio.
Which firmware are you using?
Sorry, I have it at home. I’ll let you know this afternoon.
Hello again,
The firmware I am using is: 1137B03SIM900M64_ST_ENHANCE
It should work fine. Can you connect it to pc and check on hyper-terminal or any other terminal console
Hello,
I have been testing with hyperterminal and I think that the problem is related to the tone length because if I use longer clicks on the keyboard it seems to work. Do you know if there is a length of limit for the tones to be correctly decoded?
Thank you and best regards
Antonio.
Did you try with other operators??
Yes, I have tried with another operator with the same result
hmm, I am not sure why it happens for you, I am not aware of any way to set any parameter regarding the length of tones. try to contact simcom support!
I will try to contact them. Thank you very much.
I am new here. I would like to know if we can program the SIM900 to program for Picking up the Phone after Two Rings ( Keep on looking at the Input and after 2 Rings give “ATA”)and then Play a File ( Give command AT+CPAMR=”welcome.amr”,0 ) and then keep on looking for DTMF Input and depending on the DTMF Input give the Output GPIO..
Can the program be stored in SIM900 so i dont have to use external Microcontroller..
I have used the Microcontroller and made the Program using RS232 and interfaced RS232 of the SIM900 to Microcontroller.. It works OK.. But I feel SIM900 has sufficient power to store the Program.. How to make the Program.. How to compile …And how to upload it in SIM900
Yes you can do that by embedded AT. Try searching for Sim900 embedded At
I have read the Document SIM900 Embedded AT Application Note in which they have given the API’s and detailed Description.

I havent worked on embedded AT until now! maybe some one on the comments thread have worked on , or try asking at any other forum like edaboard or stackoverflow.
Hi Antonio Yo´re in Mexico ? BR
Hi, i’ve downloaded the firwmare 1137B03SIM900M64_ST into the sim900 module,but after i downloaded the modem is not working..pls help me out
Does the modem switch on? and show registered when sim card is inserted?
If so you need to send AT command making sure AT is in CAPS just after powering up the modem.
Hi,i ‘ve dowloaded the firm ware into sim900 module at the baudarte 115200 bps,after the download complete..i tired to test the modem with AT commnads in hyprtrminal but its not working
When you flash new firmware , auto-baud is enabled which requires AT command to be sent in CAPS to recognize the baud rate. please check this Post GSM Modem/Module not responding to AT commands after firmware Upgrade??
I am new to the ham radio ‘mesh’ hobby, …but I am trying to learn it (and Linux too) !
When I try to run your software, almost ALL of it loads onto my new Banana Pi. (it does run.)
But I get one ‘failed’ message:
* Startpar failed to open vchiq *
How do I clear this ‘VCHIQ’ fail error?

Hi. please if you can help me, I built a electronic board with SIM900 and PIC microcontroller, 18F4520, to send and receive SMS, the electronic board operates well certain time (3 or 4 days) then the SIM900 Module dead, and the PIC microcontroller follows operating OK, doing others things, the communications between SIMM900 and PIC microcontroller is lost…..I have to reset the module to again operate the electronic board, but I have to go to the site and this is the problem…..I you have some Idea where is the problem…
thank you very much in advance.

I guess the problem is somewhere in the modem circuit. Any how you can implement a check in your pic firmware. Send AT and if you are not getting replies you may switch off modem using AT+CPOWD command and then switch it on. Also implement another check. I have found that when the modem loses signals sometimes it doesn’t register even when it gets back signals. For this you can keep checking registration after small intervals if it shows that sim card isn’t registered switch off modem and switch it on again.

Hello i would like to ask if anyone knows what’s the difference between modules that have
Regards Panagiotis
Enhance versions support all functions such as DTMF JD EMAIL etc
Hi, thanks for your post
But I’m a little bit confused that what is the difference between normal version and enhanced version of these firmware?
For ex: 1137B13SIM900M64_ST and 1137B03SIM900M64_ST_ENHANCED
Can they work together?
SIMCOM used to have firmwares that supported DTMF ,emails and other functions like Jamming detection and used to write those functions in the firmware version as sufix. ST for example had only standard features. Later on they integrated all these features and added suffix ENHANCED.
So, it means we can only install either standard or enhanced firmware version?
Thank you for your answer.
Yeah. And enhanced versions are the latest.
Yep, I get it. Thank you for your help.
Hello i am using a sim900A and it wont connect to the network all at commands work just it wont connect to the network. through research the firmware is to old or just wont connect to U.S. networks. Can i Flash firmware for the sim900 on sim900A?? or can i Flash the latest version of the sim900A and it work on U.S. networks?? any help would be greatly appreciated as i dont think im gonna be able to pull the sim900 i have on a shield off to put on my other pcb. Thank you also i can easily hook up rx and tx and gnd but what software do i need to use to actually flash the file onto the sim900A. Thanks!
Hi Robert,
Sim900A wont register to US networks as it is carrier locked to some Asian countries, It is a Dual band contrary to SIM900 which is Quad-band.
From documentation of sim900A
There are people who used Sim900A in other regions by Flashing SIM900 (not SIM900A) firmware.. Try it!
The software required is called sim900 flash tool.
Hi I am using sim900a GSM module. I tried to upgrade the firmware but the following errors occured.
Check target settings
Could you pls help me?
Frankly speaking I was never able to know what was the real problem with such errors , there is no proper documentation, which is common for Chinese.
Make sure you read the previous comments on this post.
Good news for me. Nice blog.
hi,
Anybody please tell how to use DTMF decoder inside the sim900. I have sent AT+DDET=1 and it response with OK. But when I make a call to tmy SIM900 and press some key on my the mobile phone, I received nothing. I have tried all the firmware for SIM900 module posted here, but nothing happened. Thanks you
I have faced similar problems as well. Sometimes some mobile networks will not send DTMF signals. Try with another network or from a land-line.
thanks admin for sharing such a cool post

What i have done wrong?
Greetings Ralf
After Powering ON send “ATr” a number of times. AT should be in CAPS.
Let me know if that worked.
Hello,
now it works fine without any problems.
I made the mistake to use low caps for first contact.
Thanks Ralf
Good. When you flash new firmware , auto-baud is enabled which requires AT command to be sent in CAPS to recognize the baud rate!

Where are you from? SIM900A is restricted to some countries, you may use to unlock it for other operators and countries.
INDIA
There might be some issues with your circuit etc. Sim900A will work india.
The SIM900A-model is locked to these regions:
China
India
Singapore
Malaysia
Thailand
Indonesia
Cambodia
Vietnam
Laos
Burma

I am not aware of that, did u tried the enhanced firmware
sir,
I'm trying to send an image to a phone using MMS. I am able to get to the point where my serial monitor says “CONNECT”. From my understanding of the SIM900 MMS manual, that means that the module is now ready to receive data. I am not sure about how to get the module read the data. I am trying to get an image from the SD card to the module.
Right now, I'm using this to read from the SD card and send it to the SIM900 module:
File dataFile = SD.open(“datalog.txt”);
// if the file is available, write to it:
if (dataFile) {
while (dataFile.available()) {
Serial.write(dataFile.read());
}
dataFile.close();
}
It's not working. Eventually, the module waits there for the time specified in the AT command and prints “ERROR” on the serial monitor.
If anybody could offer some help, it would be GREATLY APPRECIATED!!
thanks

If you're planning on using an Arduino Duemilanove to update the firmware:
1. remove the Arduino's ATMEGA chip (we're flashing with the smd FTDI chip and this'll only interfere with the process)
2. connect the SIM900 RX to D0 (RX) and the SIM900 TX to D1 (TX)
If you don't remove the ATMEGA prior to trying to flash the chip you might receive the following error(s):

Thank you.
Hello
We are working on a project having sim900A as the GSM/GPRS module .The PCB board designed and fabricated is as per the reference design shown in one of your technical document.The board works fine with most of the service providers(In India service providers are Vodafone ,Tatadocomo etc),but this module fails with the sim provided by India's largest Service provider Airtel.
When we start the system it works fine with the airtel sim but when we start loading it(Sending sms ) ,it starts giving this error- “+CPIN Not ready” and then we are not able to access the SIM900A module.
Can you please provide any help on this.
Poison also stated that he was facing problem with airtel- contact simcom
Hello Naren,
I was facing problem with Vodafone(India) but i got rid of that problem using long wired antenna..
You may try it..

Hello! I have a SIM900 board from elecfreaks ( http://dx.com/p/efcom-pro-wireless-850-900-1800-1… ). Came with firmware 1137B06SIM900M64_ST. Update to 1137B11SIM900M64_ST and 1137B12SIM900M64_ST. Updated with SIM900 Series download Tools Customer 1.6. No error. Now board boots up and seems to work judging by the led lights. But, cannot communicate with hyperterminal like before. Tried all baudrates and of course the default 19200 8-N-1. What can be wrong? Funny thing is that I could downgrade from B12 to B11 using the same serial interface.
What can be wrong? Did I brick my module?
Thank you!!
Bruno
hello friend,
i need help regarding firmware update of sim900 gprs shield.
i have arduino mega 2560 which doesn't has FT232 chip. please tell me the procedure how to update firmware for sending MMS AT commands. I have downloaded this.
(1137B03SIM900M64_ST_MMS.zip 7.43 MB)
to upgrade u need to connect the TX and rx of the sheild to your PC and use the flash uploader program to upload the new firmware. Which sheild are you using?
Hi! I have put 1137B08SIM900A32_ST on my SIM900A module but after that it is not registered in network.
AT+CPIN? returns +CPIN: PH-NET PIN . what it mean? Thanks
Chinese are very bad with documentation. So i dont know what does that error code mean
There can be two problems. Either problem with the connection or board settings or with the module. Some times the module wont upgrade although it was working fine before upgrade process.
Which board are u using. Can u share a snapshot of ur setup?

Hi Dost,
See the messagens of the errors”Simcom – sim900 Customer flash loader V1.01″:
Regards
http://www.elecfreaks.com/3275.html. Check this page to see how would u connect ur sheild to pc
Ok!
Thank you
Did you solve the problem?
I am also getting this error while upgrading the firmware, but i don't have SIM900 shield. I have GSM module which connects through serial port.
Usually it happens but following measures might help you out
# keep the power_key pin low through out the update process.
# make sure you use the default baud rate of the loader software
# if the default baud rate fails again and again try using 115200 as baud rate
# retry !
Hi i have the same error. Could anyone Pls tell me what to do about it
Dear Dost!
When I use the “Simcom – sim900 Customer flash loader V1.01” with Arduino Uno/Atmega16U2 it doesn't work.
Do you have any tip how to use the Arduino Uno for change the firmware of the SIM900?
Could you help me?
Regards,
Arnaldo
Sorry but its not clear.. how are you using sim900 flasher with arduino UNO,? which sheild are you using??
Hi Dost!
No problem I'll try explain you of another way.
I've a Arduino UNO hardware and this shield: “http://www.elecfreaks.com/store/gprsgsm-shield-efcom-p-415.html”. I put inside of the Arduino this code for comunication with shield:
void setup() { // initialize D0 pin as an input: pinMode(0, INPUT); // initialize D1 pin as an input: pinMode(1, INPUT); } void loop(){ //none }When I used the “Simcom – sim900 Customer flash loader V1.01” the software stoped on the step 6 (Click the START button to download, you will see window like the one below).
Can I used Arduino for change the firmware (SIM900)?
Is there other hardware to comunicate with shield?
Thank you for your time!
