Problems to read motors

Hi everyone! I’ve been working for a few weeks in a rover, i bought the autopilot apm 2.8 but at the moment when i connect everything and tried to test the motors with the mission planer it tells me ''command was denied by autopilot". I don’t know what else to do, i did everything.

APM 2.8 is a waste of money, to be honest. It does not run Ardurover 3.5. The last version that runs on it is 2.5, if I remember correctly. Most of the settings/features shown in Missionplanner will not work. Use the full parameter list to set it up.


It is a real waste of money… Thank you!
