Allows you to send NMEA GPS data from your device to legacy devices. You can use a CH340G adapter with an OTG cable and connect anything that uses NMEA via serial with a standard baud-rate of 9600. Can also be used with Arduino. This app will keep running in the background until the service is stopped. So, you can lock your screen to save power. However, due to high GPS activity the app will drain the battery fairly quickly, so keep that in mind. This application uses location in the background in order to send your location in a NMEA string using UART to your devices even when the screen is off or the application is minimized. Your location is processed only on your device and is never sent to third parties.
