I am super frustrated getting the tello to respond to a GameSir Gamepad T1. I get the controller to sych to bluetooth on my I phone at least the light indicates it is then when I open the app for the tello making sure it is connected to wifi I then hit "connect"it always takes me to the permissions screen and the only way out is to go back to the app which takes me to the permission screen over and over. I have flown it before with the app and phone control, but really wanted to use the controller. I have read the documentation numerous times and can't find the secret, what am I missing? I find forums such as this to be goldmines of information as usually others have experienced the problem or known of it, thanks for any help to get me launched.
