Just went to fly my Tello after some down time and it looks as though aTP will only connect via Bluetooth vs. USB. Does that mean I can no longer use my Gamesir T1s?
Would suggest you check your cable and adapters. Perhaps there was an update to the phone's OS that change some settings.
aTelloPilot was last updated March 12, 2019 and believe has ceased development. Try to message @bluejune (the developer) but does not seem to be active on this board lately.
