.. _bluetooth-hci-ipc-sample: Bluetooth: HCI IPC ################## Overview ******** This sample exposes :ref:`bluetooth_controller` support to another device or CPU using IPC subsystem. Requirements ************ * A board with IPC subsystem and Bluetooth LE support Building and Running ******************** This sample can be found under :zephyr_file:`samples/bluetooth/hci_ipc` in the Zephyr tree. To use this application, you need a board with a Bluetooth controller and IPC support. You can then build this application and flash it onto your board in the usual way. See :ref:`boards` for board-specific building and programming information. To test this sample, you need a separate device/CPU that acts as Bluetooth HCI IPC peer. This sample is compatible with the HCI IPC driver provided by Zephyr's Bluetooth :ref:`bt_hci_drivers` core. See the :kconfig:option:`CONFIG_BT_HCI_IPC` configuration option for more information. You might need to adjust the Kconfig configuration of this sample to make it compatible with the peer application. For example, :kconfig:option:`CONFIG_BT_MAX_CONN` must be equal to the maximum number of connections supported by the peer application. Refer to :ref:`bluetooth-samples` for general information about Bluetooth samples.
