hello,i encountered the same problem on my rover when it is in guided mode. Have you solved it?

I’m facing the same trouble. Did you find a solution by any chance?

Have you tried DO_SET_REVERSE?

Thank you for helping, but I didn’t find it between the parameters I can manage from my gcs for Rover firmware…
