Bluetooth Mesh
Application Overview
Enabling the interconnection of all things

With the continuous advancement of technology, standalone device intelligence is rapidly evolving. In fields such as smart homes, industrial control, commercial lighting, and smart buildings, the demand for networked smart products has shown significant growth trend. As one of the most mature protocols in traditional short-range wireless communication technologies, Bluetooth is keeping pace with the times by introducing a brand-new networking technology—Bluetooth Mesh.

System Structure

The RTL8762 series Bluetooth Mesh solution supports the combination of advertising and GATT connections to build a mesh network, enabling the interconnection of all devices in smart home scenarios.

Application Structure

Practical Application Case

Application Cases

The Bluetooth Mesh 86 Box based on the RTL8762 series is a network management hub (Provisioner) with an integrated screen. It supports device provisioning, network status monitoring, and smart scenario control. Through touchscreen interaction and multi-protocol coordination capabilities, it delivers a visual, low-threshold user experience for whole-home smart systems.

1 Device Provisioning & Network Management
a. Visual onboarding guidance: One-click device discovery and addition via graphical interface.
b. Network security management: Multi-user permission control (admin/guest modes) to restrict device operation scopes.

2 Multi-mode Interaction & Control
a. Touchscreen interaction: Directly control lights and view device status via the screen.
b. Scenario quick-access: Customizable scenario panels for one-trigger multi-device coordination.

Application Cases

The Bluetooth Mesh smart lighting system based on the RTL8762 series can wirelessly receive control commands from switches, sensors, or gateways. It parses dimming instructions and responds to status queries through Lighting Models while also serving as a relay node to extend network coverage.

1. Support for Standardized & Custom Models
a. Standard Models: Supports SIG Mesh Lighting Models (on/off/brightness/color temperature control), Scene Model (scene storage), and compatibility with mainstream ecosystem commands.
b. Custom Models: Provides Vendor Model Samples to support private function definitions (e.g., special lighting effects, customized device status reporting formats).

2. Multi-mode Network Control
a. One-touch group control: Simultaneous response for 200+ lights with high consistency.
b. Group addressing: Light grouping by room/function, supporting independent or coordinated operations.

3. Smart Scenario Integration
a. Localized rules: Light sensors trigger automatic dimming (configurable thresholds).
b. Cloud integration: Implements “Sunrise Mode” gradual wake-up via weather API synchronization.

Application Scenario

Creating intelligent lighting environments for smart buildings
Application Scenario
Commercial Lighting

Users can easily control thousands of lights in a mall or parking lot through the Bluetooth Mesh network. By utilizing the multicast address feature of the Bluetooth Mesh network, users can also achieve zoned management of the lighting. This lighting system enables dynamic zonal dimming and energy consumption monitoring through the Bluetooth Mesh network, and it can also perform remote bulk firmware upgrades, thereby reducing wiring costs and operational complexity.

Empowering industrial automation and intelligent operations & maintenance
Application Scenario
Industrial Control

The relay mechanism of the Bluetooth Mesh network can cover complex factory environments and support networking with tens of thousands of nodes. This network can transmit device data to the control center in real-time, ensuring communication reliability through flooding and directed forwarding mechanisms, thereby enabling production line automation and predictive maintenance.

Enabling seamless interconnection for smart homes
Application Scenario
Smart Home

The Bluetooth Mesh network enables efficient device interaction in smart homes, enhancing the user experience. Through the Bluetooth Mesh network, users can operate devices and manage lighting, security systems, and environmental control devices in real-time using a smartphone or voice-controlled gateway.
