(A better tablet might be a reasonable approach. Beware that every vehicle is different and that coatings on windows matter.) There are two approaches: direct support in the program, and mocking. This assumes you are using Android. Direct support means the program can connect over bluetooth SPP, perhaps BLE, and perhaps serial port and get an NMEA stream and use it directly. QField can do this. I am not aware of osmand having direct external GPS receiver support. Mocking means enabling developer mode, and having a program that implements direct support, and then injects the position data (NMEA?) via a developer API so that everything else on the tablet sees the injected data. That is intended for testing/debugging, but it is widely used for external support. An example program is https://apt.izzysoft.de/ftp/repo/fdroid/index/apk/com.clearevo.bluetooth_gnss and that does bluetooth but not clearly serial (USB is surely serial over USB). However, if you find a program you like you can then buy an external GNSS unit that works with it. Note that with mocking, you may want to figure out if the tablet is still running the internal receiver, but if it is plugged in to power from the train, you may not care. -- You received this message because you are subscribed to the Google Groups "OsmAnd" group.
