Pixhawk 2.4.8 with FTDI


I have a problem connecting Pixhawk with FTDI (USB-UART FT232RL) to Companion Computer.

I am following these instructions, but without results: GitHub - mavlink/c_uart_interface_example: Simple MAVLink to UART interface example for *nix systems

What can be wrong?

Thank you!!!

I would recommend to use MAVSDK or something else instead. The c example is rather cumbersome and incomplete.

Is this jumper for logical voltage switching ? Have you changed it from 5V to to 3.3V?

Also how about this point, I see you are connecting your FTDI board to TELEM port:
