I disable some pre arm check feature (GPS and RC).Because I dont have

I take a error

Can you help me

Hi @earas48,

Sorry for the delayed response.

Could you please explain how did you disable them?

Do I take it right that the issue is in altitude measurements?
Could you please check what’d be the output if you run the barometer example?

Hello ,
Firstly I use ARMING_CHECK=0 command.I see that current altitude values from screen.When I measure the output pin voltage that enter esc,I can not see any voltage,Do you think Can I perform system without rc controller,esc … .At the moment I dont have any equipments.I have only navio 2,I have to see voltage on the output pin so
I want to disable all of pre arm check

Hi @earas48,

Have you provided servo rail with the power supply? Can I see the output of the ADC example so I can check it out?

Hi I use servo rail utilizing raspberry pi 5v pin and I also measured output servo rail pins.These are 5v and I used example.Servo motor runs properly.

Hi @earas48,

Could you please clarify if I understand correctly that you want to measure the signal output on servo rail?
