I’m using the Q2682 for GPRS interfacing it with a 32 bit controller running Linux. I understand that the modem has an inbuilt TCP/IP stack and runs openAT OS. My question is , since i am able to achieve a connection (start the stack, connect to bearer,send data,disconnect etc) via the supported AT commands, is there someway i can create a socket from my host (ie micro-controller) and map it to the GPRS connection? The idea is to provide a socket interface to the higher layers without exposing the transfer of data (between the MCU and modem) via serial communication
Is ppp a way to achieve this? From what i understand from the man pages,ppp is the protocol used for establishing Internet links over dial-up modems.Now isn’t this ‘establishment’ already done using the AT commands mentioned earlier?
