We have an issue where when we are connecting to the Pixhawk PX4 through UAVcast and an error shows up saying - a serial link port is dead. Wondering if anyone else has run into this issue?
Have you connected your PX4 with USB cable?
Some cables wont work, and i guess that is due to the voltage drop in the cabel itself.
Try using another usb cable.
You should se valid serial link found
Sinamics That was the issue. After trying a couple more usb cables and moving the port to a different port on the RPI we were able to get a connection consistently. Thank you very much!
