.. _bluetooth_unicast_audio_client: Bluetooth: Unicast Audio Client ############################### Overview ******** Application demonstrating the LE Audio unicast client functionality. Scans for and connects to a LE Audio unicast server and establishes an audio stream. This sample can be found under :zephyr_file:`samples/bluetooth/unicast_audio_client` in the Zephyr tree. Check the :ref:`bluetooth samples section ` 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_client/ :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_client/ :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 ` :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_client/ :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 `. Building for a simulated nrf5340bsim ------------------------------------ .. zephyr-app-commands:: :zephyr-app: samples/bluetooth/unicast_audio_client/ :board: nrf5340bsim_nrf5340_cpuapp :goals: build :west-args: --sysbuild
