INTERFACING ARM WITH WAVECOM MODEM

Wavecom modems may be programmed themselves for required functionality .
Yet if needed an external interface then they can be controlled through serial port i.e. interface your micros (ARM) serial port to the serial port of WAVECOM modem and control it through AT commands. The commands can be found in wavecoms document.

(Some) Wavecom modems have some general-purpose IO (GPIO) pins in addition to the serial port - so that's also an option for communicating with another processor (I2C is supported).

The Wavecom modem cotnains a powerful ARM CPU, so any processing can be done within the modem; the external microcontroller would just need to be a simple IO controller - probably no need for another ARM there!
