GPS Connector

If you activate the mock location feature on your smarthone you can use NMEA data like location, speed and accuracy in any other app. (e.g. Google Maps)
Activate mock location

• switch on "Set Mock Location" in the GPS-Connector app settings and
  optionally set the desired "mock height" to orthometric or ellipsoidal
• Select the "mock location app" in the Android developer options as well
  Android12::Settings > System > Developer options > scroll down to "mock location app"
  >> now select the "GPS Connector" app
  >> or simply tap on "Developer options" on the settings screen
• if you don't see the developer options on your smartphone, just activate them:
  it depends on the Android OS version of your phone how to activate the developer options, e.g.:
  Android V11/V12: Settings > About phone > Build number (click 7 times on the "Build number" text)

To check if the mock-location feature works just set "Simulation" as "GNSS Input" in settings and switch to Google Maps.
The location should jump now between different cities, like Munich, Berlin, Paris, etc.
