Use bluetooth device as an input in 4a (4a-hal & 4a-softmixer)

Description

The use of a bluetooth device as an audio input in 4a must be implemented ASAP.

What is needed :

  • Development of a '4a-hal' controller plugin that will get the connected bluetooth device. It must register itself to AGL bluetooth network service (provide by connectivity) to stay informed of the connected bluetooth devices.

  • Provide the bluetooth hardware address to 4a-softmixer.

  • Creation of an input PCM using the received bluetooth hardware address in '4a-softmixer' (an example is available in 'bluealsa-aplay').

  • Use the previously created PCM to stream audio from the bluetooth device to speaker output.

Hi

https://git.automotivelinux.org/apps/agl-service-bluetooth-pbap/tree/binding/bluetooth-pbap-binding.c is an example of the PBAP service monitoring bluetooth devices via the Bluetooth service. There's also an example in the telephony binding which is part of the phone app.

Hi ,

As describe in the above JIRA ticket, we need to get (and to stayed informed of) the currently connected bluetooth device(s) to implement use of bluetooth in 4a.

Do you know if there is a way to register an application framework binder (4a in our case) to bluetooth service to stayed informed of the currently connected bluetooth devices ?

Thanks in advance for your response.

Regards.
