There are two probs with that:
- The RIL does not expose that function
- You may send AT^moni command to GSM modem but this may disturb or corrupt the RIL. The RIL is sending and parsing all commands to control the modem. Think of the RIL being the wrapper around all modem communication.
- You need a comm port to send (inject) AT commands to the modem. That may be implemented or not by the RIL driver.
- If the modem does not support AT^moni you are lost. The Siemens MC75 supports cell monitoring via:
AT^SMONC Cell Monitoring The AT^SMONC execute command delivers cell information containing 9 values from a maximum of 7 base stations. The first base station is the serving cell.
AFAIK Sierra Modems do support AT^moni too. Qualcomm? Don't know.
