Bluetooth : Maintaining connections simultaneously with multiple devices.

[By_design]

Interesting situation, but I was using one smartphone as a mp3 player, and the other was my always-on-phone. I missed calls completely while listening to the mp3. How can you know that everything is connected? A phone call has to get received by both the headset and the smartwatch simultaneously. It us usually much easier to control volume on the headset, rather trying to find the controls on the watch, but I am sure there will be new developments that require good Bluetooth control between the watch and the headset. Does each additional connection add hardware requirements of each device?

Am I right in assuming you were listening to music from the non-phone device on a BT headset that you also use to connect to a phone?

If so then you won't be able to hear both simultaneously. BT headset audio is one to one, you can't connect to two devices at the same time. The phone call never gets "received by the headset", it gets received by the phone, but of course you won't hear it if the headset is not connected because it's being used to listen to music from another device.

Think of a BT headset as much the same as a corded headset but without the cord; it then becomes clearer why you can't hear the phone when you're "plugged into" a separate MP3 player.
