| Bluetooth: Broadcast Audio Sink |
| |
| Overview |
| ******** |
| |
| Application demonstrating the LE Audio broadcast sink functionality. |
| Starts by scanning for LE Audio broadcast sources and then synchronizes to |
| the first found and listens to it until the source is (potentially) stopped. |
| |
| This sample can be found under |
| :zephyr_file:`samples/bluetooth/broadcast_audio_sink` in the Zephyr tree. |
| |
| Check the :ref:`bluetooth samples section <bluetooth-samples>` for general information. |
| |
| Use `CONFIG_TARGET_BROADCAST_NAME` Kconfig to specify the name (CONFIG_BT_DEVICE_NAME) |
| of a broadcast source to listen to. With default value (empty string), sink |
| device will listen to all available broadcast sources. |
| |
| 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 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/broadcast_audio_sink/ |
| :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/broadcast_audio_sink/ |
| :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 nrf5340bsim |
| ------------------------------------ |
| |
| Similarly to how you would for real HW, you can do: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/bluetooth/broadcast_audio_sink/ |
| :board: nrf5340bsim/nrf5340/cpuapp |
| :goals: build |
| :west-args: --sysbuild |
| |
| Note this will produce a Linux executable in `./build/zephyr/zephyr.exe`. |
| For more information, check :ref:`this board documentation <nrf5340bsim>`. |
| |
| Building for a simulated nrf52_bsim |
| ----------------------------------- |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/bluetooth/broadcast_audio_sink/ |
| :board: nrf52_bsim |
| :goals: build |
| :gen-args: -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf |
