Hi,
I only know a few controllers that work via Android Bluetooth with the original
Tello app (
GameSir T1d,
GameSir T1S work).
However, your Xbox controller may work with the ideal
Tello app “
Tello FPV”, please try the trial version first. Activate the location on your smartphone beforehand.
And if you manage to connect your Xbox controller to the smartphone via OTG cable, you will have a better, more stable image transmission and a longer range.
I wish you success
