""As of 6/30/2015, DJI has only enabled the ground station features on the Inspire 1 firmware. The Inspire 1's public firmware is fully functional with our app. There is a known bug in the DJI SDK which causes video lag, but there is a good workaround and we expect that this issue will be solved soon. The public Phantom 3 Professional firmware doesn't support any ground station functionality and will not work with this app until DJI releases public firmware that contains that support."
Ground station enabled on the Inspire...!?!!?
