Hello As my first serious ardiuno project, i am trying to make the arduino uno send me a sms when someone enters a certain room. I have setup the arduino and installed the SIM900 GPRS Shield without any problems. I am using a unlocked FreeMobile sim card (France). When I power on the shield the green LED blinks every three seconds.
By following this wiki I have gotten to step 4 of Fun With AT commands > Step 1: Test Setup http://www.seeedstudio.com/wiki/GPRS_Shield_V2.0
However I am unable to communicate with the shield through sscom32e (the recommended serial tool). I have chosen the correct com number (the one i successfully used to upload the basic blink example to the arduino) and I have set it to operate at 19200 8-N-1.
When following the next steps, i get this result :
AT+IPR=19200 OK AT+CMGF=1 ERROR
I have tried getting a more detailled error without success
And i have tried to see if text mode is supported again without success
Thank you in advance for the help Blabby
