GATT Specifications | Bluetooth Technology Website

Bluetooth Generic Attributes

Generic Attribute Profile (GATT) is built on top of the Attribute Protocol (ATT) and establishes common operations and a framework for the data transported and stored by the Attribute Protocol.  For more information on GATT, please refer to Volume 0, Section 6 of the Bluetooth Core Specification.

The documents in the “Informative document showing changes” column are provided as a courtesy to help readers identify changes between two versions of a Bluetooth specification. When implementing specifications, use the adopted versions in the “Adopted Version” column.
