I think I may have an solution for anyone experiencing constant "compass redundancy switch / compass error" errors during flight. You need to do a firmware restore.
Downgrade to V01.02.0900, make sure to restart the aircraft afterwards. Then upgrade to V01.03.0200. Restart the aircraft again. Go outside and do an IMU calibration as well as a compass calibration, being at least 10 metres away from any metal or steel structures. Also make sure to have no mobile on you or other device with cellular or wifi connection. When doing the compass calibration, make sure to point the Mavic downwards during the second part of the calibration.
Once you've done that, restart the aircraft and do a test-flight. Errors shouldn't be coming up at all, or at least be coming up a lot less. At least that's how things went down for me a little while ago this morning.
If your compass details look like mine here in HealthyDrones, everything is fine.
Here's the flight-log of my latest flight if anyone's interested.
I went out at least 1260 metres in distance and at an altitude of around 300 metres with no signal interference issues. I didn't get any compass redundancy switch errors, only the occassional compass error, possibly due to fog being present in the area but no constant compass errors, so that tells me that both compasses are working fine, which I'm really glad about. Flight conditions were terrible with loads of fog, and an temperature of around 4 degrees. Can't see anything when above 100 metres. Mostly flight above clouds. Aircraft came back with quite a few wet spots, but still fully working. |
