Hi everybody, I recently purchased a GSM/GPRS shield identical to the one used in the example posted by Erel and uploaded the GSM_Example code. Unfortunately it doesn't work. More specifically, I noticed that in GSM Module, the "busy" variable remains setted to TRUE after the Sub SendCommand is executed, therefore I cannot send any SMS.
I also forced the execution of the sub by commenting the line
but, anyway, it doesn't send any SMS.
I tried uploading the source code via the .ino sketch attached and it works properly.
I also tried to substitute the original code in the Sub EnableSMSEvents with the "AT+CMGF=1" command, and to add the slashes (\) to the phone number, but I failed.
Has anyone an idea of what I've done wrong?
Thanks in advance
Maurizio
