That's interesting.
From the bluetooth joystick settings it tells me to:
1 turn on the controller
2 Enable Bluetooth on your mobile device
3 Open Tello app
4 Confirm the connection in the Bluetooth joystick settings.
I just assumed you'd see your new controller in that setting...argg
I've tried both the GameSir G3 and T1s and no luck.
I think that's because the Gamevice is not a Bluetooth controller. it hooks up via lightning port. I ordered a Moga Ace Power that works the same way. If it works I just spent the best $11 of my life.
I should also clarify I'm using an iPhone SE. Although the Moga is kind of old and originally for the 5 and 5S, I have read it works with the SE on a couple sites. Lastly, the Moga was the same price of the Gamevice when it came out.
