 * The GATT module is responsible for providing an API for all attribute related operations.
 * It is responsible for all the service framework activities using the Attribute protocol
 * for discovering services and for reading and writing characteristic values on a peer device.
 * To achieve this, the GATT interfaces with @ref ATTM "ATTM", @ref ATTC "ATTC" and the
 * @ref ATTS "ATTS".
