If GPS over Wi-Fi (NMEA) is on, launch the GPS-enabled app on the computer then configure it to utilize a NMEA port or GPS receiver.
Refer to the app's help menu or contact the app developer for assistance.
Once the app has found the NMEA port / GPS receiver, it should report "Waiting for your location" or similar until a GPS fix is obtained. After that, it uses or displays the current GPS location.
