Arduino -> MAvPROXY -> RF LINK -> PIXHAWK - ARDUINO

[sigm...@gmail.com]

Hello ,

On my Quad copter , i have an arduino dedicaded to do some multiple task ( light management , camera control over visca protocol etc etc ) ,

on my GCS , i have a raspberry pi ( mav proxy ) , and a station with apm planner 2 , and finally and arduino to manage multiple button and light on the GCS


I've see that on the mavlink protocol , you an use ID for the subsystem .

So my question :

Does the pixhawk can't send custom command the the onboard arduino if the subsytem ID is not the one of the pixhawk ?

Thanks !
