Regarding the Ground Station functionality that's embedded into the DJI vision app, I know that the waypoints are uploaded to the phantom via the Wi-Fi, but can I also assume that control signals such as "pause" and "Return-To-Home" from the DJI vision app GUI are also sent via the Wi-Fi link? I think they must be since there's no interface between the app on the smart phone/tablet and the controller. Also, how do the limits compare between the DJI vision app and the "stand-alone" Ground Station app? Specifically, I'd like to know if the stand-alone app (with bluetooth data link) allows for a greater radius than the DJI vision app. DJI Vision App Ground Station Limits: Waypoints: 16 Height: 200 meters Radius: 500 meters Distance: 5000 meters Ground Station stand-alone app (with bluetooth data link) Limits: Waypoints: ? Height: ? Radius: ? Distance: ?
