-Setup the iWave device like described in the [iwave-g26-tutorial](iwave-g26-tutorial.md) To enable
-the GPS output, open the file `/etc/ppp/chat/gprs` and add the following (for example above the
-AT+CPIN line):
-
-```
-# Enable GPS
-AT+QGPS=1

-To apply the changes you can use `systemctl restart lte`. After that you should see NMEA formatted
-ASCII data if you do `cat < /dev/ttyUSB1`
