Is it possible to connect a wired and bluetooth headset at the same time?

Question

Android

There is a smartphone Lenovo A859. In the car, I connect it via a 3.5 jack connector to an FM modulator (i.e., as if to a headset to listen to music) The
question is - if you also connect a bluetooth headset to this circuit (for talking exclusively) - will everything work correctly? Those. if they call me and I answer the call, will the call go to the bluetooth headset, and not to the car speakers? And after the end, respectively, the music should return to the wire. In general, is it possible to configure this behavior?

Answer 1

In theory, you can, in the settings of the Blutooth device there are checkboxes - media sound transmission and speech transmission. Disable unnecessary. It is more difficult to pick up forced forwarding on the wire

Answer 2

Something like this
