Not sure this is possible, but would be nice if you could somehow scrape the GPS coordinates off a Garmin smart watch such as Garmin Instinct or Garmin Fenix. These have bluetooth but connect to Garmin's free app. You would somehow need to analyse the bluetooth comms to see if it's possible. This would enable many more users to use your app, since there are a lot of these devices out there and Garmin watches have pretty accurate GPS's. One use case would be for more accurate GPS and to save battery consumption on the android phone.
