I tried unsuccessfully to help a friend sync her Inspire 1 using the ipad air. She has been flying the Phantom 3 Professional and the app has worked flawlessly. When trying to get the app to sync to the inspire, it does not ask to register the quad...the only thing it shows is the tab that shows the steps to connect. I tried my ipad and it worked perfectly. After going through the registration process and flying it with my ipad, I tried, unsuccessfully again, to connect using her ipad. Does anyone out there have any idea why it won't connect to her inspire, even though it works with her phantom 3?
