I have a phone and a tablet that I would like to connect via Bluetooth to an Amplifier in my car. I would like to be able to easily switch the audio between the two devices. eg, quickly switch from the tablet which is playing music to the phone in able to answer a phone call.
Is it possible to connect the 2 devices via Bluetooth to a Raspberry Pi and route the audio through to the amplifier? Can I have a switch on the Raspberry Pi that toggles between the phone and the tablet?
