Public Broadcast Profile (PBP) Public Broadcast Source
Overview
Application demonstrating the PBP Public Broadcast Source functionality. Will start advertising extended advertising and includes a Broadcast Audio Announcement. The advertised broadcast audio stream quality will cycle between high and standard quality every 15 seconds.
Check the 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:
# From the root of the zephyr repository
west build -b nrf5340dk/nrf5340/cpuapp --sysbuild samples/bluetooth/pbp_public_broadcast_source/
If you prefer to only build the application core image, you can do so by doing instead:
# From the root of the zephyr repository
west build -b nrf5340dk/nrf5340/cpuapp samples/bluetooth/pbp_public_broadcast_source/
In that case you can pair this application core image with the HCI IPC sample 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:
# From the root of the zephyr repository
west build -b nrf5340bsim/nrf5340/cpuapp --sysbuild samples/bluetooth/pbp_public_broadcast_source/
Note this will produce a Linux executable in ./build/zephyr/zephyr.exe.
For more information, check this board documentation.
Building for a simulated nrf52_bsim
# From the root of the zephyr repository
west build -b nrf52_bsim samples/bluetooth/pbp_public_broadcast_source/ -- -DEXTRA_CONF_FILE=overlay-bt_ll_sw_split.conf
