Bluetooth Low Energy Mesh Light Protocol

Last Updated on : 2022-11-24 09:20:04download

This topic describes how to configure standard fields and control methods for Bluetooth Low Energy (LE) mesh lights. After you complete the configuration, a provisioner, typically the app or gateway, can then provision a Bluetooth LE mesh light.

Note: The app in this topic can be Tuya Smart app, Smart Life app, Tuya OEM app, and the app you developed with Tuya App SDK.

Configure provisioning

For more information, see Bluetooth LE Mesh Protocol Specification.

Mesh category

The light is a standard device type and its product category value is 0x01. The specific product types are as follows:

Product	Mesh category
Cool white light ©	0x1011
Cool and warm white light (CW)	0x1012
Multi-color light (RGB)	0x1013
Cool white and multi-color light (RGBC)	0x1014
Cool and warm white and multi-color light (RGBCW)	0x1015

Element and model description

An element is an addressable entity within a device. This means that it is some part of a device that has at least one, independent state value that represents some condition of the element. All nodes must have at least one element. Some nodes will have multiple elements. A model defines a set of states, state transitions, state bindings, messages, and other associated behaviors. An element within a node must support one or more models and it is the model or models that define the functionality that an element has.

Element cnt: 1

model id	Model	Description
0x0000	Configuration Server model	Configure a device. For example, add or delete a group.
0x1000	Generic OnOff Server	Switch the device on/off and detect heartbeats.
0x1300	Light Lightness Server	Adjust light brightness.
0x1306	Light CTL Temperature Server	Adjust light color temperature.
0x1307	Light HSL Server	Adjust light colors.
0x000407d0	Tuya vendor model	Implement custom light control such as light mode, scene mode, and music light.

Common model opcode

Model	Opcode	Description
Generic OnOff Server	Generic OnOff Get	Query device on/off status.
Generic OnOff Server	Generic OnOff Set/Generic OnOff Set Unacknowledged	Switch the device on/off with or without acknowledgment.
Generic OnOff Server	Generic OnOff Status	Respond to device on/off status.
Light Lightness Server	Light Lightness Get	Query light brightness.
Light Lightness Server	Light Lightness Set/Light Lightness Set Unacknowledged	Adjust light brightness with or without acknowledgment.
Light Lightness Server	Light Lightness Status	Respond to light brightness.
Light CTL Temperature Server	Light CTL Temperature Get	Query light color temperature.

Light HSL Server	Light HSL Get	Query light colors.
Light HSL Server	Light HSL Set/Light HSL Set Unacknowledged	Adjust light colors with or without acknowledgment.
Light HSL Server	Light HSL Status	Respond to light colors.

Light data point (DP)

DP ID	DP function	Model	Remark
1	On/Off	OnOff Model	None
2	Mode	Vendor Model	Switch between white light and multi-color light.
3	Brightness	CTL Model Lightness	None
4	Color temperature	CTL Model Temperature	For Bluetooth LE mesh light, the value ranges from 800 to 20000.
5	Colors	HSL Model	The DP data is represented in the HSV model. The app or gateway will convert the DP data into the one in the HSL model and sends it to the light.
6	Scenes	Vendor model	Vendor’s pass-through data.
7	Countdown	Vendor model	Vendor’s pass-through data.
8	Music	Vendor model	Vendor’s pass-through data.

Note: For lights, DP 2, DP 6, and DP 8 are specially treated. The rest of the DPs using the vendor model and other custom DPs all conform to Vendor Model Pass-Through Specification.

Special vendor DPs

DP 2	Vendor model	If the data length is one, the model ID is sent directly.
