    Any reason why the vision app ask for a compass calibration if a good one were done 2 days ago. I did a good compass calibration in an open space in a soccer field two days ago, and today when trying to take off from a third floor in the terrace of my apt, were I usually fly and less than a mile from the calibration site, the app don't let me take off only after a compass calibration. And did it, although not the best place to do it.

    Thanks Geert. Maybe the altitude difference was the reason. Have read that the last firmware take care to diminish the fly away problem, so maybe this is why it ask for the calibration more often.
