I am using EC200U-CN development module. I installed the drivers and QNavigator . But when I try to access the GNSS, it is showing no ports available. I also looked the device manager, there
You can just use the Uart tool to open the NMEA port.
You should send the AT command
AT+QGPS=1
first.
Not all the EC200U support GNSS.
After sending the AT+QGPS=1 command, it repeatedly receives,
[2024-11-12 15:30:27:085_R:] $GNRMC,V,N,V37
[2024-11-12 15:30:27:092_R:] $GNGGA,0,00,99.99,56
[2024-11-12 15:30:27:101_R:] $GNGSA,A,1,99.99,99.99,99.99,133
[2024-11-12 15:30:27:107_R:] $GNGSA,A,1,99.99,99.99,99.99,436
[2024-11-12 15:30:27:112_R:] $GPGSV,1,1,00,065
[2024-11-12 15:30:27:112_R:] $GNVTG,N2E
OK.
That is the NMEA port.
You should send the AT command
AT+QGPSPOWER=1
If you still cannot see the location from the nmea log, please check the GPS antenna.
