I have a MOD-GSM olimex board incorporating Sim340DZ GSM module.
I am interfacing it with my PIC32 MAXI WEB Olimex controller board.
The strategy is I have defined a receiver interrupt to receive responses from GSM Modem.
And I send the commands to the GSM modem via simple transmission
via polling till all data is sent on the UART Port.
I am able to send the dial command and dial any number and end a call but
I am not getting any responses on the receiver interrupt of the microcontroller
from the MOD-GSM board. Moreover I am also unable to connect to GPRS
while issuing commands only as I cannot see responses of the commands,
as are they OK or ERROR. So my requirement is GPRS connectivity of
my module and sending the string to the server with a specific IP and Port number.
Please inform me your previous work related to the GPRS project.
