I have a challenge on my hand now; am doing a project that involves me displaying the communications processes between the MS and the BTS during (1) MS powering up (2) Voice call (3) Sending text messages. I am using Maestro 20 GSM modem and i have been able to operate it (send text, make voice call) using AT commands via hyperterminal. My challenge now is how to code and integrate a NXP LPC 1768 MBED microcontroller with the GSM modem with the aim of displaying the communicating protocols/signals between the MS and BTS on the MBED screen or a larger screen. Presently , i have been able to create a virtual serial port for the LPC 1768 MBED that i am using (since it connects via USB) by installing serialPC driver and it works better with TeraTerm. My challenge now is how to send AT commands (as a code) to the modem through the MBED and also get the normal modem response from the modem unto my MBED. If anyone has an idea of how i can pull this through, i will much appreciate your contribution.
I hope i have been explicit enough and i will appreciate greatly a pointer in the direction to go.
Thanks all
