I have a problem with my Matek405 Wing, I can t enter esc calibration. I tried with two different Hobbywing Skywalker 50A esc’s, they both do the same: just keep beeping oblivious to the throttle position.
I use the latest version of Ardupilot, I can see in Mission Planner the throttle servo channel working properly when I arm. All other servo channels work fine and I do get servo motions normally.
I have tried to reduce/increase the throttle servo channel min/max, still nothing. I tried arming while having GPS fix and no active error messages and arming through MP, still nothing. The esc starts beeping at a steady tone when I power it on with max throttle and armed
2manual mode, when I cut the throttle it just continues beeping. When I reboot everything, it starts beeping again even with throttle 0.
According to the ESC manual this beeping pattern suggests an irregular throttle signal. However, while reviewing the throttle channel and RC throttle bar, the signal has zero flickering.
I have set BRD_SAFETYOPTION=0 in case a safety switch did the trick, nothing.
It s the third night trying to solve this issue and it s getting a little frustrating. It s my first arduplane so be gentle with me! Any ideas please?
