4. GNSS Debugging
4.1. General AT commands
Commands
Description
Return
AT+CGNSPWR
GNSS Power Control:
AT+CGNSPWR =1:Turn on
AT+CGNSPWR =0:Turn off
OK
AT+CGNSTST
AT+CGNSTST=1:Send data received to AT Port
AT+CGNSTST=0: Stop sending data received to AT Port
OK
AT+CGNSINF
GNSS navigation information parsed from NMEA sentences
+CGNSINF:
OK
4.2. GPS Debugging
1) Connecting the GPS antenna, and place the receiver on open area outdoor
2) AT+CGNSPWR=1 //Turn on power of GPS
3) AT+CGNSTST=1 // Start to sending data received to AT Port
Open u-center and set the Port and Baudrate(AT Port, COM25).
Of course, you can use another port(NMEA Port,COM27)
4) AT+CGNSTST=0 // Stop sending data received to UART
5) AT+CGNSINF // Print the GPS information
6) AT+CGNSPWR=0 //Turn off power of GPS
