4in1 ESC Hobbywing

Hi

I have tried to connect a 4in1 ESC (Hobbywing) to my pixhawk mini. I have the RC signal on pixhawk mini, but when i try to calibrate the ESC it doesnt works. Is i required to configure something special that a 4in1 ESC is working with a pixhawk mini?

I am not an expert but maybe you should configure anf flashes your ESC
