BLE profiles and applications

A service collects a set of characteristics and exposes the behavior of these characteristics

(what the device does, but not how a device uses them). A service does not define

characteristic use cases. Use cases determine which services are required (how to use

services on a device). This is done through a profile which defines which services are

required for a specific use case:

•

Profile clients implement use cases

•

Profile servers implement services

A profile may implement single or multiple services (available and specified at

http://developer.bluetooth.org).

Standard profiles or proprietary profiles can be used. When using a non-standard profile, a

128 bit UUID is required and must be generated randomly.

Currently, any standard Bluetooth SIG profile (services, and characteristics) uses 16-bit

UUIDs. Services & characteristics specification & UUID assignation can be downloaded

from the following SIG web pages:
