This app utilizes the GPS available on an Android device to supply information to a gpsd server.
The app supports blindly relaying whatever NMEA sentences it reveives from the underlying OS location mechanisms, as well as generating it's own NMEA sentences using the location data, provided by the OS.
For this to work, the device needs to have a GPS fix available and the gpsd server has to be reachable by the device via IP.
or get it from the Releases section.
The main tab has a button that starts the relay server.
The settings tab contains all the available preferences.
