Transclusion: IOT-GATE-iMX8: GPS

Optional GPS interface is implemented with the cellular modem module.
The cgps client can be used to display the GPS information. The cgps client utility depends on the gpsd daemon (starts automatically).

• Connect to the modem configuration port with Minicom:

root@iot-gate-imx8:~# minicom -D /dev/ttyUSB3

• Enable the GPS with the following commands:

AT+CGPS=1,1

• Verify that the OK respond is generated.
• Exit minicom (CTL-a, x).
• Start the cgps client to display GPS information.

The synchronization process might take a few minutes.

root@iot-gate-imx8:~# cgps
