The COM port / serial device should be specfied via the QT_NMEA_SERIAL_PORT environment variable before SDRangel is started. +(E.g. on Linux: export QT_NMEA_SERIAL_PORT=/dev/ttyACM0 or /dev/ttyUSB0 on Windows: Set QT_NMEA_SERIAL_PORT=COM5 via Control Panel) +This requires the Qt serialnmea plugin, which is not available in the libqt5positioning5-plugins package on Debian / Ubuntu. +It can be downloaded for Ubuntu/x64 from http://sdrangel.org/downloads/libqtposition_serialnmea.so and should be installed in usr/lib/x86_64-linux-gnu/qt5/plugins/position/. +This custom build of the pluging also allows setting the baud rate via the QT_NMEA_SERIAL_BAUD_RATE option (which is not supported on Windows nor Mac). On Android, GPS setup should be automatic. GPS position updates may stop on Android when the screen is off. To keep the screen on, press the View > Keep Screen On menu.
