| :name: Bluetooth |
| |
| These samples demonstrate the use of Bluetooth in Zephyr. |
| |
| To build any of the Bluetooth samples, follow the same steps as building |
| any other Zephyr application. Refer to :ref:`bluetooth-dev` for more information. |
| |
| Many Bluetooth samples can be run on QEMU or :zephyr:board:`native_sim <native_sim>` with support for |
| external Bluetooth Controllers. Refer to the :ref:`bluetooth-hw-setup` section |
| for further details. |
| |
| Several of the bluetooth samples will build a Zephyr-based Controller that can |
| then be used with any external Host (including Zephyr running natively or with |
| QEMU or ``native_sim``), those are named accordingly with an "HCI" prefix in the |
| documentation and are prefixed with :literal:`hci_` in their folder names. |
| |
| .. note:: |
| If you want to run any bluetooth sample on the nRF5340 device (build using |
| ``-DBOARD=nrf5340dk/nrf5340/cpuapp`` or |
| ``-DBOARD=nrf5340dk/nrf5340/cpuapp/ns``) you must also build |
| and program the corresponding sample for the nRF5340 network core |
| :zephyr:code-sample:`bluetooth_hci_ipc` which implements the Bluetooth |
| Low Energy controller. |
| |
| .. note:: |
| The mutually-shared encryption key created during host-device paring may get |
| old after many test iterations. If this happens, subsequent host-device |
| connections will fail. You can force a re-paring and new key to be created |
| by removing the device from the associated devices list on the host. |
