Hi o_o,
Is it necessary to re-calibrate the BNO055 each time the device is powered off and on again? Every time it is placed in a new operating environment?
As this is something that isn't very feasible, would an alternative mode such as IMU be acceptable as we are only monitoring relative changes in angles?
Hi o_o,
So we are looking at staying within 20 degrees (all axes) over a 12 hour period. And after various hours of runtime the magnetic calibration is seen to drop from 3 to 0 with no noticeable changes to the device's surroundings (it is left in a lab overnight).
Would we notice any changes in the gyro's calibration status after some time running in IMU mode? Would it be possible to monitor this bit and treat data accordingly?
We do have access to GPS however the device remains fixed in a stationary position and so I don't believe it would be a usable alternative.
