| .. zephyr:code-sample:: bluetooth_cap_initiator |
| :name: Common Audio Profile (CAP) Initiator |
| :relevant-api: bluetooth bt_bap bt_cap bt_conn |
| |
| Connect to CAP Acceptors and setup unicast audio streaming or broadcast audio streams. |
| |
| Overview |
| ******** |
| |
| Application demonstrating the CAP Initiator functionality. |
| Starts by either scanning for a CAP Acceptor and then connects to and sets up available unicast |
| audio streams, sets up a broadcast audio stream, or both. |
| |
| This sample can be found under :zephyr_file:`samples/bluetooth/cap_initiator` 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 ``-DEXTRA_CONF_FILE=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/cap_initiator/ |
| :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/cap_initiator/ |
| :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 nrf5340bsim |
| ------------------------------------ |
| |
| Similarly to how you would for real HW, you can do: |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/bluetooth/cap_initiator/ |
| :board: nrf5340bsim/nrf5340/cpuapp |
| :goals: build |
| :west-args: --sysbuild |
| |
| Note this will produce a Linux executable in :file:`./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/cap_initiator/ |
| :board: nrf52_bsim |
| :goals: build |
| :gen-args: -DEXTRA_CONF_FILE=overlay-bt_ll_sw_split.conf |
