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-eddystone-sample: Bluetooth: Eddystone #################### Overview ******** Application demonstrating `Eddystone Configuration Service`_ The Eddystone Configuration Service runs as a GATT service on the beacon while it is connectable and allows configuration of the advertised data, the broadcast power levels, and the advertising intervals. It also forms part of the definition of how Eddystone-EID beacons are configured and registered with a trusted resolver. Requirements ************ * BlueZ running on the host, or * A board with BLE support Building and Running ******************** This sample can be found under :zephyr_file:`samples/bluetooth/eddystone` in the Zephyr tree. See :ref:`bluetooth samples section <bluetooth-samples>` for details. .. _Eddystone Configuration Service: https://github.com/google/eddystone/tree/master/configuration-service
