supersonic sensors not working

What is this message referring to and what does it effect? I get this message when I get the connection between the camera and the ST-16s. Then the next question is how do you fix this?

I think you are refering to the ultrasonic (not supersonic) sensors. Make sure that nothing is blocking them and they are clean.

Obstacle Avoidance messages are common when the aircraft is sitting on the ground. Don't turn on OA until you are at least 10' above the ground.

Good one We all wish our drones where supersonic, but ultrasonic sounds faster??
