Pixhawk - ESC calibration

ArduCopter Copter 3.2
1

First post and my first quadcopter build - and I have an ESC calibration problem.

Config:
Afro20 ESC with SimonK connected to Pixhawk with signal and ground
Pixhawk powered from power module
UBEC powering Pixhawk servo rail
X8R receiver SBUS connected to PC on Pixhawk and RSSI out connected to SB on Pixhawk
some servos and relay switches are powered (no signal wire) from the servo rail

Following the procedure I enter to calibration mode with Pixhawk and hear beep from ESC but moving the throtle minimum no confirmation signal from ESC. ESC/Motor does not react to throtle movement.

I researched the internet and forums but no conclusive suggestion; I tried with (and also without) pushing the arming button.

ESC’s user guide refers my to the flight controller’s calibration process.

Any suggestion please?

Have you tried just manually programming the esc’s? Disconnect them from the pixhawk and plug each one into your ch3 port on your rx. Follow the programming from your manufacture, usually plugging in the multi’s power with the throttle stick at full, wait for a particular set of beeps and lower the throttle to min.

Thanks, after manual calibration I tried again and I could complete without problem.
