I am using the GSM-shield (+leonardo) for sending and recieving SMS messages.
The first SMS I send with my code works perfect, aufter that SMS my board does NOT send any SMS-Messages any more.
The return value of the endSMS-Function is always 0, which means that action is still working.
Can anyone give me a hint where's my bug?
void sendSMS(char nr, char msg)
Reveiving SMS messages is working without problem! :~
Thanks for a short advice!
