Mariusz Skamra ba61420504 Bluetooth: audio: ascs: Retry ASE state notifications on error This adds retry logic for ASE state notifications if failed due to insufficient number of buffers to send ATT PDU. The state transition is retried after connection interval delay. Fixes: #64574 Signed-off-by: Mariusz Skamra <mariusz.skamra@codecoup.pl>		2023-11-15 10:03:07 +01:00

Bluetooth: Unicast Audio Server
###############################

Overview
********

Application demonstrating the LE Audio unicast server functionality.
Starts advertising and awaits connection from a LE Audio unicast client.

This sample can be found under
:zephyr_file:`samples/bluetooth/unicast_audio_server` in the Zephyr tree.

Check the :ref:`bluetooth samples section <bluetooth-samples>` for general information.

Requirements
************

* BlueZ running on the host, or
* A board with Bluetooth Low Energy 5.2 support

Building and Running
********************

When building targeting an nrf52 series board with the Zephyr Bluetooth Controller,
use `-DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf` to enable the required ISO
feature support.

Building for an nrf52840dk
--------------------------

.. zephyr-app-commands::
:zephyr-app: samples/bluetooth/unicast_audio_server/
:board: nrf52840dk_nrf52840
:goals: build
:gen-args: -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf

Building for an nrf5340dk
-------------------------

You can build both the application core image and an appropriate controller image for the network
core with:

.. zephyr-app-commands::
:zephyr-app: samples/bluetooth/unicast_audio_server/
:board: nrf5340dk_nrf5340_cpuapp
:goals: build
:west-args: --sysbuild

If you prefer to only build the application core image, you can do so by doing instead:

.. zephyr-app-commands::
:zephyr-app: samples/bluetooth/unicast_audio_server/
:board: nrf5340dk_nrf5340_cpuapp
:goals: build

In that case you can pair this application core image with the
:ref:`hci_ipc sample <bluetooth-hci-ipc-sample>`
:zephyr_file:`samples/bluetooth/hci_ipc/nrf5340_cpunet_iso-bt_ll_sw_split.conf` configuration.

Building for a simulated nrf52_bsim
-----------------------------------

Similarly to how you would for real HW, you can do:

.. zephyr-app-commands::
:zephyr-app: samples/bluetooth/unicast_audio_server/
:board: nrf52_bsim
:goals: build
:gen-args: -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf

Note this will produce a Linux executable in `./build/zephyr/zephyr.exe`.
For more information, check :ref:`this board documentation <nrf52_bsim>`.

Building for a simulated nrf5340bsim
------------------------------------

.. zephyr-app-commands::
:zephyr-app: samples/bluetooth/unicast_audio_server/
:board: nrf5340bsim_nrf5340_cpuapp
:goals: build
:west-args: --sysbuild
