Not recieving COMMAND_ACK or MISSION_ACK for some commands in PyMavLink
I am trying to control a drone using PyMavLink. The drone has a pixhawk board running arducopter software. V4.5.5 (Newest).
I also have the newest pymavlink version. V2.4.41
For some commands, I recieve an ACK, however for others I dont. I dont know if this is because my code is incorrect, or for other reasons.
I can arm the drone, change modes, but I cannot liftoff and move around, even without any console errors.
