Switching off GPIO2
at#gpio=2,0,1
These LEDs can be controlled e.g. by an external microcontroller via at-commands
issued to the terminal via the serial RS232 interface. They can be used for signalling
any useful status of the external application such as:
- error indication
- status of communication (GPRS, SMS, CSD, etc.)
- status of GSM-network (to simulate GSM LED)
- quality of service
