Sorry Roshan, I do not have access to any sim300 firmware at all. Simcom removed it all earlier this year and I have none downloaded

Hi All,
I managed to get a few programs running in the SIM900 using the Embedded AT (EAT) functionality and the API provided. One inconvenience in using EAT is the unavailability of new firmware versions which support EAT functionality. Currently the only firmware version I have that supports EAT is "1137B07SIM900M64_ST.cla". This one actually came with the SimDev IDE which Chipseller (kindly) provided.

I've tried uploading newer firmware versions like "1137B08SIM900M64_ST" and "1137B09SIM900M64_ST" but EAT doesn't function with those. Anyone with a more recent version of the EAT supported firmware? If you have, I'd appreciate a lot if you can share it.

That aside, writing a program to work with EAT turned out to be much trickier than I expected. It's a unique environment, and IMHO SIMCOM guys haven't really thought about user-friendliness when the designed the whole thing. On top of that, their example applications are unnecessarily complicated and documentation is sparse. Any how, after days of tinkering, think I finally got the hang of it. If anyone wants some help in the programming side of EAT, let me know.

Hi thedinuka,
thank you for this offer. I would appreciate some help. I want to start a development with the SIM900 using the EAT and API.
Some time ago I programmed a MotorolaG24 GSM modem, which has a JAVA api inside. So I am not a newbie in this area. But I know how complicated things can get or sometime how simple the answers can be. I would like to exchange some experience with you, if this is ok for you.
My first question is, where do I get the RVCT2.2 2_2b616 compiler?
My application is that I need to talk to a system (let say an external device, connected to the serial port of the SIM900) via RS232. Periodically the SIM900 need to send some commands to the device and receive a status message. If there is an error in the device status, the SIM900 has to establish a connection to a server and send this status message to that server via tcp. Thats the task. Is this kind of application possible with the EAT?
Thanks for your help
 
Hello guys, anyone has any idea about SIM908-C flash update, also can anyone help me out with getting SIMCom NMEA GPS DEMO Tool?
 

Hi chipseller,

I am using the SIM900B module. But i am having problem with the Email AT Command, all it give is the Error response.
Can you confirm that Revision:1137B09SIM900B32_ST is the latest firmware for SIM900B?
If it is not can you give me the latest version.

Best Regards,
Chew
