Call Control Profile (CCP) Call Control Server
Overview
Application demonstrating the CCP Call Control Server functionality. Starts by advertising for CCP Call Control Clients to connect and set up calls.
The profile works for both GAP Central and GAP Peripheral devices, but this sample only assumes the GAP Peripheral role.
This sample can be found under samples/bluetooth/ccp_call_control_server in the Zephyr tree.
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 -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf to enable the required 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/ccp_call_control_server/
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/ccp_call_control_server/
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/ccp_call_control_server/
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/ccp_call_control_server/ -- -DOVERLAY_CONFIG=overlay-bt_ll_sw_split.conf
