BLUE SDK MESH

Bluetooth® Mesh stack for IOT
Based on Blue SDK

A New Topology for Bluetooth

Scalable. Responsive. Secure.

Bluetooth Mesh is a Bluetooth technology designed to build secure and reliable networks with large numbers of connected devices. It introduces a many-to-many communication topology that allows devices to relay messages across the network, extending range and enabling scalable system architectures.

The technology is built for resilience and scale, supporting large device networks with robust security mechanisms and reliable message delivery. This makes Bluetooth Mesh well suited for complex IoT scenarios where multiple devices must communicate efficiently and consistently.

Technical Overview

Layered Architecture

Blue SDK Mesh consists of an independent Mesh stack operating alongside a modified Bluetooth Low Energy stack. The Blue SDK Stack provides core LE functionality including ATT, SMP, L2CAP, and the LE Connection Manager, while selected components are adapted to support interaction with Mesh communication mechanisms.

Mesh communication is implemented through dedicated layers, including network, transport, access, model, configuration, and provisioning layers. Message transport uses both the Advertising Bearer and an optional GATT Bearer, while the connection manager coordinates scanning and advertising to enable controlled data exchange between the LE and Mesh stacks.
