This adds support to set different permissions to CCCD so security can be checked when enabling notification which conforms to: BLUETOOTH CORE SPECIFICATION Version 5.1 | Vol 3, Part G page 2360: '3.3.3.3 Client Characteristic Configuration Authentication and authorization may be required by the server to write the configuration descriptor.' In addition to that also ensure that notification are not re-enabled until the proper security level is reached to conform to the following statement: '10.3.1.1 Handling of GATT indications and notifications A client “requests” a server to send indications and notifications by appropriately configuring the server via a Client Characteristic Configuration Descriptor. Since the configuration is persistent across a disconnection and reconnection, security requirements must be checked against the configuration upon a reconnection before sending indications or notifications. When a server reconnects to a client to send an indication or notification for which security is required, the server shall initiate or request encryption with the client prior to sending an indication or notification. If the client does not have an LTK indicating that the client has lost the bond, enabling encryption will fail.' Fixes #17983 Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com> |

.. _peripheral_esp: Bluetooth: Peripheral ESP ######################### Overview ******** Similar to the :ref:`Peripheral <ble_peripheral>` sample, except that this application specifically exposes the ESP (Environmental Sensing Profile) GATT Service. 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/peripheral_esp` in the Zephyr tree. See :ref:`bluetooth samples section <bluetooth-samples>` for details.
