Suddenly yesterday morning the blue LED kept flashing as if a bluetooth connection was active. Even with bluetooth turn off. Bright light is quite bright and bothersome.
Battery pull will rest light if done with bluetooth turned off, but first time bluetooth is used it is back on to stay. Battery pull with bluetooth turned on results in light returning as soon as battery is put back in. When the turn power icon is used for a flight, the light stays on, just blinks much slower.
