The Generic Attributes (GATT) is the name of the interface used to connect to Bluetooth LE devices. The interface has one or more Bluetooth Services, identified by unique ids, that contain Bluetooth Characteristics also identified by ids. A 16-bit Universally Unique Identifier (UUID) may be allocated by the SIG for use with a custom GATT-based service defined by the member. UUIDs are used in Bluetooth® protocols and applications.

In the GATT settings, tick the Generic Attribute Service checkbox. In Bluetooth, attributes types, GATT service types, characteristic types and descriptor types, and other constants are identified through UUIDs. UUIDs are no more than identifiers, 128-bit identifiers. One given 128-bit value designates one given thing.

A Bluetooth profile is a specification regarding an aspect of Bluetooth-based wireless communication between devices. It resides on top of the Bluetooth Core Specification and (optionally) additional protocols.

The Bluetooth GATT SDK for Python helps you implementing and communicating with any Bluetooth Low Energy device that has a GATT profile.
