hi everyone,
I keep getting  a notice saying blue tooth interference on the app. this happens in the middle of nowhere the only thing i can think off is that its my watch. has anyone else had this problem?

Yes, bluetooth devices like smartwatches, fitness trackers, or your smartphone can cause interference because they're using the same channels as the spark/RC, which is why it is suggested to turn off bluetooth on any devices near you while flying.

Hi there, agree with the post 2#, it is recommended to disable the Bluetooth on all of the devices near you when you fly the drone.
