ESC - Pixhawk configuration problem

I’m building my first ever rov and while testing the first motor have encountered a problem with configuring them so that these respond in any way to the controller or motor tests after arming.

I’ve tested calibration and motor tests via BlueOS, QGC, and Mission Planner. The min/max pwm values are set on defalut. The BHEli_S ESC+motor being tested is connected alike a servo to the pixhawk AUX outputs - as according to the pixhawk documentation. I’ve checked the hardware with a servotester and everything worked perfectly fine so it seems like it’s missing some parameter settings in the Pixhawk, and that’s why I’m are unable to get any movement.

Could anyone describe how such calibrations looked in your setups? (which parameters were changed, maybe anything that’s easy to overlook)?

Hardware:
PC, Raspberry Pi, Pixhawk 2.4.8, BHeli_S ESC, A2212 motor, 12V battery

Hi @KEFiR-reytan -

Welcome to the forums!

Are you sure your ESC is bidirectional? It may be failing to initialize with the 1500 microsecond servo style pwm signal it is receiving from the ArduSub autopilot…

Can you share a picture showing your connections to the pixhawk? What frame are you using? The connections should be made like this.
