I´m developing and app. (hardware) that is supposed to transmitt data using GPRS to a PC connected to the internet.
1) I know that I have to stablish a PPP connection to my server, but after that how do I send my data (a bunch of numbers from a database)? Should I go for TCP/IP? What´s the recommend protocol in this case?
2) I know that I can access another hardware that is also connected using GPRS (same ISP let´s say). Is it possible to transmitt data between then without TCP/IP?
