I use a Gamesir T1s and Tello FPV. Up to today I would plug in my OTG cable, the 'A' for Android light would come on steady, and I was in business. Now, all the "mode indicator" lights flash on and off and I have no connection. I tried connecting with the Tello App and it will only connect via Bluetooth. Using Tello FPV I can't connect at all. Any thoughts on how to rectify this problem?
