Question: I would develop an application that may communicate two devices using Rs232. I will connect them to a GPRS modem. I found a service that offers IP non dynamic, I will use what they call a corpotarive APN that may allow me to get an IP that will not change.
My question is this: I start my application sending AT commands to get the modem connected to GPRS, but after that how would I use the IP to connect to the other modem, would it be using AT commands. I got confuse because I do not get the idea on how to develop an application that use IP if the connection to the network is done by a modem.
I would appreciate any comment
