AT#GPRS is part of the module’s internal TCP/IP stack handling procedures (it activates GPRS session) – so is not using Linux TCP/IP stack.
The second method with ATD*99***1# and PPP is to use Linux networking; I suppose the problem in your case is flow control mismatch, you can disable it in GSM module with AT&K0 or, better of course, enable it in PPP (I think options file, crtscts) and of course make required hardware lines connected.
ahhh ok, I get it now….GSM tcp stack and linux tcp stack….cheers for that!!!
At this stage it
Cosmin youre a genius, thank you!!!!
I tested minicom with the AT&K0 and bingo I received the “CONNECT” string.
