To ensure the compatibility for message exchange between different kinds of Bluetooth Mesh devices, Bluetooth Special Interest Group (Bluetooth SIG) defines a series of generic and standard models for Bluetooth Mesh applications, including Generics, Sensors, Time and Scenes, and Lighting, which enable Bluetooth Mesh devices to control a peer Bluetooth device or obtain the device information, facilitating Mesh applications in different scenarios.

This document elaborates on how to use standard models and develop applications with these models by taking the Light Lightness (LLN) Models in Lighting Models for example.
