Compass redundancy switch warning (never seen it before)

[xblackxopsxsecretsx]

Hi I flew a bunch of times on my s7 but when I first tried my Ipad air 2 while flying in sports mode a error popped up saying "Warning: compass redundancy switch" so I landed DJI chat said to re calibrate IMU and compass. Any idea what happened? I was flying in my backyard open field area like always. i'm on the last firmware and app is updated...

I got the same message today on my iPhone - second flight since the update.
Found that it was not as stable as normal, and started to drift a bit on the first flight, but no message. Today also not as stable as normal and the message appeared.

well even after imu and compass recalibrated it did it again after 5 seconds on sports mode -_-

I am getting this message since .400. I read here that it may be early Mavs with a wire too close to the motor wires and that DJI was RMA'ing those Mavs. So far when it happens to me and I look at the compass, both seem fine...not sure why it's switching and if it's a concern. It behaves fine and doesn't seem to impact anything in my case.

But granted when I stopped and looked at the compass, I wasn't flying fast. Supposedly, that is what causes the motor RFI to affect the compass causing the switch to compass 2, or 1 if it was already on 2. It happens to me both in Sport Mode and regular makes no difference. I see this on just about every flight.

There is a DIY fix for this here.
