In order to use Bluetooth technology, a device must be compatible with the subset of Bluetooth profiles necessary to use the desired services. 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
Profiles are definitions of possible applications and specify general behaviors that Bluetooth enabled devices use to communicate with other Bluetooth devices. Profiles build on the Bluetooth standard to more clearly define what kind of data a Bluetooth module is transmitting. The device’s application determines which profiles it must support, from hands-free capabilities to heart rate sensors to alerts and more
The Generic Attributes (GATT) define a hierarchical data structure that is exposed to connected Bluetooth LE devices
