This is the documentation for the latest (master) development branch of Zephyr. If you are looking for the documentation of previous releases, use the drop-down menu on the left and select the desired version.

Bluetooth samples

To build any of the Bluetooth samples, follow the same steps as building any other Zephyr application. Refer to Developing Bluetooth Applications for more information.

Many Bluetooth samples can be run on QEMU or Native POSIX with support for external Bluetooth Controllers. Refer to the Hardware 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 POSIX), those are named accordingly with an “HCI” prefix in the documentation and are prefixed with hci_ in their folder names.

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.
