Has anyone used the GSM GPRS module to create an always on network connection, where the module is constantly connected to the Internet without making a phone call? How easy would it be to have a PIC send and receive data over a connection like this?
I have played with the GPRS a bit. I am lost on the socket connection. What do I do to my computer to open a socket? What program can I run? Terminal maybe? Not sure. I will let you know as soon as we can get data moving back and forth to a PIC.
www.gm862.com is probably the place to ask. The US/GPRS section is very good source.

I get the gm862 to connect and run gprs continually until I shut it down, but the pic is having a hard time talking to it I see the serial passed from the pic into hyperterm but the gm862 does not recognize the text coming in as command information. I think I need to high and low the pins correctly. but the key is to give the at command a good amount of time before issuing another one.
does anybody tried sending data thru GPRS using PIC to the server/IP/Socket…if so help me in doing so.
