Note: The GPS antenna must be placed outside before it can obtain a stable GPS location data output.
Send AT + CGSN PWR = 1 command (Open the GPS power)
Send AT + CGNSTST = 1 command (Receive GPS data from the serial port)
If the GPS antenna has been placed outside, you should get the right data soon.
When you want to pause GPS data output, you can sent AT + CGNSTST = 0 command to pause GPS data output.
When you want to turn off GPS function, you can send AT + CGNSPWR = 0 command to turn off the GPS power. Send AT + CPOWD = 1 to shut down the
