I have a couple P3 Pros. On one of my birds, I have been getting an "Ultrasound Error - Land as soon as possible." This error usually occurs about 5 - 8 minutes into a flight. There are no other problems. Flying with latest software. Using iPad mini 3. I have done IMU calibration and gimbal calibration to no avail. I do a compass calibration before each flight.
When I land on autopilot, the bird comes down pretty fast. When ultrasound actually works, it slows down a few feet before touchdown.
Any thoughts regarding cause and solutions? Thanks!
