Hi, I’m using pixhawk 2.4.8 in MP. I’m trying to calibrate ESC. It gives the expected beeps to confirm calibration but when I try to rise throttle a bit, the motor does not turn. When the throttle is at halfway (middle point), it starts to run. Why isn’t it responding between %0-%50 throttle range? RC calibration is true by the way. Also, it works normally when i try it just by connecting motor to third channel of the RC receiver (disconnecting RC receiver-pixhawk connection). It gives 0%-100% range as it should be. It also works when I use pixhawk orange cube as controller. What might be the problem on pixhawk 2.4.8?
Try the semi-automatic ESC calibration
