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).
- Select the GPS interface:
root@iot-gate-imx8:~# sed -i "/^DEVICES=.*/c\DEVICES=\"/dev/ttyUSB1\"" /etc/default/gpsd
- Enable the GPS with the following AT commands:
root@iot-gate-imx8:~# echo AT+CGPS=0,1 | socat - /dev/ttyUSB3,crnl root@iot-gate-imx8:~# echo AT+CGPS=1,1 | socat - /dev/ttyUSB3,crnl
- Start the cgps client to display GPS information.
The synchronization process might take a few minutes.
