Hi to all!!. I made a GPRS/GSM application thanks to your help, so once more im really thanksfull to all of you.
Now, my aplicattion is ready and function, sendig small packets to a server and recieving small responses from it and it works just fine for the first 45 minutes, then it just freezes. The CPU dont send any traces to the M2M so i dont know whats happening but response tho the AT commands that i send in the Shell. There is some kind of watchdog timer or something that is blocking my CPU??. Please note that i`ve tried this twice with different packet sizes but it takes the same time to freeze!.
Once more time, thanks.
