Just figured DroneDeploy may want to add in the walk though to do a cold start IMU calibration after upgrading to DJI SDK, and checking values prior to a flight. This is a good habit to get in on any firmware upgrade, and takes a little bit of the burden off of DD if there is an issue later by having a bad IMU reading. Fresh start up on a level surfaces/calibrate IMU. Just a thought.
When I upgraded to the DJI beta it gave me an IMU calibration error. Not sure if it was just me or just a coincidence.
Most likely it was because the IMU was too warm already. I would try again from a fresh, cold start. That’s the only time I have heard of the IMU calibrations failing.
