That's the thing. There's a difference between being paired and being connected. You can have a hundred headsets paired with your phone, but you can only use one headset at a time during an active call. My suspicion is that when the bluetooth headset takes over the audio gateway, the bracelet disconnects because to the phone it's basically just another headset device. Are you using the built-in bluetooth functionality for the bracelet or something like smartwatchm?
