Thanks Mr. Cube for the reply. Actually I have some 500 pcs of TC35i and I got them from a tracking device (mature product). The device was sending GPRS data to some server. Now I am interested in using these modules in one of my application which also demands GPRS access. All I need to do is to send a packet of data to a server.
Although I have bit experience of designing electronics and providing solutions but unfortunately I am not familiar with the PPP protocols or the scheme that I need to implement to have it working.
Another point that I request you to notice is that I am using TC35i. TC35 was GSM modem while TC35i also supports GPRS according to documents.
It will be very helpful if you can provide bit details about your experience with using GPRS on TC35i modems.
Any document or application note can solve the problem, I think!
Regards
