That all looks correct.

Have you checked whether any bytes are arriving? E.g. using screen? If not, it would be some electrical issue. Make sure Tx and Rx are crossed over (so tx goes to rx and vice versa), and make sure GND is also connected.

You are using an old version of MAVSDK (and PX4). Is that on purpose?
