Good to know, although I never turned it off while flying.

Thanks for sharing! Wish you have a great time!

If using OTG i shut it off to prevent interference good thing im staying on IOS 10 with JB

I've never turned off BT or WiFi while flying my spark and haven't had any issues.

I did have some problems. Perhaps due to my apple watch. Just turned bluetooth off.

But now we have to have it on from what we know if we want to keep are warranties since "OTG isn't recommended". Thanks DJI
