This app will not update to new firmware. It will say networking issue. The calibrating is totally messed up! After calibrating the T1D remote, the tello drone will work for 5 mins then it will drift all over the place causing the drone to crash.
I can’t play games or anything I wish this application established connection so u could do so
If you can help that would be great
Is this only for one kind of controller or can this work with other controllers like a ps4 controller?
