I have and use a Huawei Mate 10 pro when flying the Tello. I have bluetooth and everything when connecting to the Tello without problem. Does your mate find the wifi from tello at all or is it not connecting to the wifi?
It is a pleasure to welcome you to the Tello Pilots forum.
I hope that you will be able to use the forum for the exchange of innovative ideas and as a resource for current developments in Tello quadcopters.
