I'm trying to fly my exa in autotune flight mode, unfortunately during my indoor test I can't invoke it.
As you can see in the attached imagery once I switch on flight mode 3 pixhawk refuses to accept this mode and keeps the previous one.
As you can see the PWM signal is between the treshold, but somehow it will be rejected by pixhawk.
If I use a different flight mode 3 (anyone) it will be accepted, see image below.
As last thing I have thought that perhaps I couldn't set it as a flight mode so i tried to use channel 7, which I normally use for RTL mode, but eventually even in this case Autotune flight mode will be rejected.
is there anyone who can help?
