On the Phantom you did the horizontal 360 and got the green light, then the vertical 360 and if I remember correctly you got flashing greens. End of story. On the Inspire, I do the horizontal 360 and the amber turns green then the vertical 360 and the light remains green and nothing changes. The message on the app says "do you want to cancel compass calibration". So I'm not sure whether it's finished or not ? The Inspire flies fine so I guess the compass calibration must be fine and the value is about 1500.
