I just put together my first drone. The problem is that whenever I try to connect the FC to Betaflight via USB, It tells me that there was a failure to open serial port. I have checked all my wires over several times, tried multiple different cables, and tried to use the Speedybee app. The app detects the board but when i try to connect it tells me that I need to enable UART4 at baud rate 115200. I'd love to hear any suggestions...
