Hello,
I used all obvious uart ports on my Pixhawk 4 and I am now trying to figure out how to use the “hidden” ones.
I can see 7 serial on the arducopter config for the board, but I guess there is only a few I can use easily.
I know there is Rx/Tx on the Fmu debug port so I guess it is probably serial 5 ?
If any one knows how I can use this Fmu debug port or any other uart/serial on the Pixhawk 4, it would help me a lot.
Thanks,
