Hello

Im having problems with my bluetooth telemetry which is connected to UART0 on my board. The BT module is configured to the baudrate 115200 and it works as long as usb is connected to my computer. I read in this thread http://diydrones.com/forum/topics/apm-2-6-schematic that the APM changes state when it's connected via USB or powered by lipo. When it's powered with a lipo (airborne mode) then UART0 is configured to use baudrate 57600. I've tried changing the bluetooth module to baudrate 57600 aswell but then it doesn't work neither in USB or in "lipo" mode.

I hope that there is a solution to this.

    For a good idea of how the board is config.

    Why not connect the Bluetooth on the telemetry port?
    • I've tried connecting it to the telemetry port aswell but that doesn't work either. Tried both 57600 and 115200 baudrate on the BT module. When I connect to it in Driodplanner I just see "unknown" as flightmode and no parameters/position cant be loaded. 

      I've also tried connecting with USB to a tablet but that doesn't work either.
