I just installed the DJI E310 propulsion system and I getting the ESC accusing throttle not at lower position (yellow led blinking fast) even though it is at the lowest position. I've tried throttle cut that takes it to a even lower value but nothing changed.
I used the ESC assistant software to check every esc/motor and all results were good. The assistant didn't indicate the necessity to upgrade firmware but I did it anyway in one ESC and the throttle high position persisted.
The controller is an APM 2.5.
Does anyone know what could be happening and what I could do to solve this issue?
Solution:
Somehow the ESC read the PWM value set for the throttle channel (1130, in my case) as not the lowest.
So I changed the APM setting for the minimum value as 1000 and the alert from ESC despaired.
