When developing Bluetooth applications, you typically run into some errors. If you are an experienced Bluetooth developer, you would typically know how to translate the error codes into string representations. Others might not. This commit to adds string printing of error codes for all samples to make them more user-friendly. Several formatting alternatives were considered. The chosen alternative balances code readability and FLASH size (with and without string printing). Example output from the peripheral_hids sample when the peer rejects pairing: ``` Bluetooth initialized Bluetooth authentication callbacks registered.

.. _bluetooth_direction_finding_central: Bluetooth: Direction Finding Central #################################### Overview ******** A simple application demonstrating the BLE Direction Finding CTE reception in connected mode by requesting transmission of a packet containing Constant Tone Extension by connected peer device. Requirements ************ * Nordic nRF SoC based board with Direction Finding support (example boards: :ref:`nrf52833dk_nrf52833`, :ref:`nrf52833dk_nrf52820`, :ref:`nrf5340dk_nrf5340`) * Antenna matrix for AoA (optional) Check your SoC's product specification for Direction Finding support if you are unsure. Building and Running ******************** By default the application supports Angle of Arrival and Angle of Departure mode. To use Angle of Departure mode only, build this application as follows, changing ``nrf52833dk/nrf52833`` as needed for your board: .. zephyr-app-commands:: :zephyr-app: samples/bluetooth/direction_finding_central :host-os: unix :board: nrf52833dk/nrf52833 :gen-args: -DEXTRA_CONF_FILE=overlay-aod.conf :goals: build flash :compact: To run the application on nRF5340DK, a Bluetooth controller application must also run on the network core. The :ref:`bluetooth-hci-ipc-sample` sample application may be used. To build this sample with direction finding support enabled: * Copy :zephyr_file:`samples/bluetooth/direction_finding_central/boards/nrf52833dk_nrf52833.overlay` to a new file, :file:`samples/bluetooth/hci_ipc/boards/nrf5340dk_nrf5340_cpunet.overlay`. * Make sure the same GPIO pins are assigned to Direction Finding Extension in file :zephyr_file:`samples/bluetooth/direction_finding_central/boards/nrf5340dk_nrf5340_cpuapp.overlay`. as those in the created file :file:`samples/bluetooth/hci_ipc/boards/nrf5340dk_nrf5340_cpunet.overlay`. * Copy :zephyr_file:`samples/bluetooth/direction_finding_central/boards/nrf52833dk_nrf52833.conf` to a new file, :file:`samples/bluetooth/hci_ipc/boards/nrf5340dk_nrf5340_cpunet.conf`. Antenna matrix configuration **************************** To use this sample with Angle of Arrival enabled on Nordic SoCs, additional configuration must be provided via :ref:`devicetree <dt-guide>` to enable control of the antenna array. An example devicetree overlay is in :zephyr_file:`samples/bluetooth/direction_finding_central/boards/nrf52833dk_nrf52833.overlay`. You can customize this overlay when building for the same board, or create your own board-specific overlay in the same directory for a different board. See :dtcompatible:`nordic,nrf-radio` for documentation on the properties used in this overlay. See :ref:`set-devicetree-overlays` for information on setting up and using overlays. Note that antenna matrix configuration for the nRF5340 SoC is part of the network core application. When :ref:`bluetooth-hci-ipc-sample` is used as the network core application, the antenna matrix configuration should be stored in the file :file:`samples/bluetooth/hci_ipc/boards/nrf5340dk_nrf5340_cpunet.overlay` instead.
