I powered on my SIM808 module. It showed me following output:
RDY +CFUN: 1 +CPIN: READY Call Ready SMS Ready
It supposed to show
GPS ready also.
I sent AT command and return ok.
AT+CGPSPWR=? returns error. All GPS command showed error.
I think GPS is not initialized at all as i didn't see GPS message when module powered on.
Why is the GPS not working?
