hi,
I built an Raspberry pi 4 and navio2 drone and I connected 4 lidar sensors via USB adapter, but I only see first 3 rangefinders, I don’t see the fourth one.
it says
rangefinder1
rangefinder2
rangefinder3
but no rangefinder 4 so how do I add the fourth rangefinder/lidar sensor to mission planner/ ArduPilot?
