.. zephyr:code-sample:: bluetooth_bap_unicast_server
:name: Basic Audio Profile (BAP) Unicast Audio Server
:relevant-api: bluetooth bt_audio bt_bap bt_pacs
Use BAP Unicast Server functionality.
Overview
********
Application demonstrating the BAP Unicast Server functionality.
Starts advertising and awaits connection from a BAP Unicast Client.
This sample can be found under
:zephyr_file:`samples/bluetooth/bap_unicast_server` in the Zephyr tree.
Check the :zephyr:code-sample-category:`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/bap_unicast_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/bap_unicast_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/bap_unicast_server/
:board: nrf5340dk/nrf5340/cpuapp
:goals: build
In that case you can pair this application core image with the
:zephyr:code-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/bap_unicast_server/
:board: nrf52_bsim
:goals: build
:gen-args: -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf
Note this will produce a Linux executable in :file:`./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/bap_unicast_server/
:board: nrf5340bsim/nrf5340/cpuapp
:goals: build
:west-args: --sysbuild
