It was with Copilot. As I have the test result having no issues without copilot, I now only test with copilot attached how to improve the situation here.Is this with Copilot or without? I assume you also used a BT controller?
And yes, by default I always have a Gamesir T1d attached as this is my default way of flying the Tello. Therefore I also cannot switch off BT as it was suggested here by someone (ok for a test of course yes, but it cannot be the solution). For myself as a Workaround I potentially could change to a controller that doesn't need BT because it can be connected to the phone via USB (means additional invest as I currently don't own one).
But especcially for the approach I'd like to use the Copilot - using two Gamesirs via BT so that master and student both can have a real controller, the USB controller solution is again out (I don't want to have meters of cable between my phone and the student's controller).
I will give this a try in the evening and let you know.Please try to reduce the Video thread priorities (drainer, handler, receiver) to 3 or 4.
If that does not work, can you confirm that it works OK in the 1.3c version (see attached).?
1.3c is an older version than the one I received from Play Store?
