I'm having problems with IMU calibration.

[ED_0405]

I link my iPhone to the bird, start the calibration and after the 2nd position the connection to the iPhone drops and the bird shuts down. I've restarted many time with the same result. any ideas?

Could be overheating
Try to blow on the bottom vents or go to a cold room while calibrating

I had the same problem. I tried to recalibrate after changing a motor, but it was failing with Error 29 (or something like that). You have to close the settings overlay to see the error message, which is really bad app design.

I've restarted the drone a couple of time and the calibration worked again.
