At what altitude?OBS.Avoidance is not available. After new firmware this is what I'm getting when I turn OBS on. every thing else is ok what is going on here anyone any Ideas.
I suspect that improbable readings from the ultrasonic sensors can also trigger this. I experienced this once when I powered up the Typhoon while sitting on a drivewau where the surface started sloping upwards at a steep angle just in front of the Typhoon.
On power-up the drone is likely doing a self-check or diagnostic, and if the sensor reports a object in close proximity, that could indicate a malfunctioning sensor. Tall grass might also trigger this.
