My wife has a BellaBeat Leaf fitness tracker. One of the features is mediation. During a meditation playback it's supposed to have an active connection to the tracker. But the connection seems to drop out after less than a minute. I've tried this on a Samsung Galaxy S3 (running Android 4.4.2) and an LG G4 (running Android 6.0). Both of those phones work fine.
You can google more information about this particular tracker. This tracker uses Low Energy BT (not sure if that's relevant) .Connecting to our bluetooth speaker appears fine.
Any ideas, we're still within the return policy for the phone. So if we dont' get this working soon then I guess we'll be moving to something else.
