To check if power has raised it is possible to monitor the PWRMON line, when this line goes high the module is powered on, but before it remains on the device needs other 900 ms for software startup. Hence check the PWRMON line and 900 ms after its transition to high it is possible to release the ON# pin.

GM862-QUAD / PY Software User Guide 1vv0300747 Rev. 3 - 10/07/07 2.5 Checking GSM device functionality After a proper power on the device is ready to receive AT commands on the serial port. Several things have to be checked in order to be sure that the device is ready to send and receive calls and SMS: 2.5.1 Autobauding At startup it is necessary to send an AT command to make the device set the right speed and character format of the serial port. When this is done the device responds with OK.
PAGE 15
GM862-QUAD / PY Software User Guide 1vv0300747 Rev. 3 - 10/07/07 2.5.2 SIM presence checking After autobauding the first thing to check is the SIM presence and PIN code insertion, this can be done with the following commands: 2.5.2.1 Enable the Extended error result codes • send command AT+CMEE=1 • wait for OK response or if you prefer the verbose format instead of the numerical format then: • send command AT+CMEE=2 • wait for OK response 2.5.2.
PAGE 16
GM862-QUAD / PY Software User Guide 1vv0300747 Rev. 3 - 10/07/07 2.5.2.3 Provide SIM PIN (only if required see point 2.5.2.2) • send command AT+CPIN=**** where **** stands for the SIM PIN code (e.g. 1234) • wait for response: Response OK ERROR Reason SIM PIN was correct the PIN code inserted is not correct Action Proceed ahead Retry from par. 2.5.2.
