Featured Bluetooth Mesh Applications

Mesh networking is a new topology available for Bluetooth Low Energy (LE) devices that enables many-to-many (m:m) communications. It's optimized for creating large-scale node networks and is ideally suited for building automation, sensor networks, and asset tracking solutions.

Home/Building Automation

Beaconing

Commercial Lighting

What is Bluetooth Mesh?

Bluetooth mesh enables Bluetooth devices to be used as a true mesh networking topology. It allows moving away from the typical personal area network which Bluetooth is known for, and extending both the range and number of devices a Bluetooth network can have. A smart home is a great example and use case for Bluetooth mesh as it can easily have 30-50 devices that are not necessarily in the direct range of each other. With Bluetooth mesh, you can connect all these devices into a single Bluetooth network that covers the entire home. Bluetooth mesh nodes can still support the existing Bluetooth LE topologies and use cases like point-to-point connectivity and Bluetooth beaconing. This allows smart phones to be connected to the Bluetooth mesh networks to control and monitor the Bluetooth mesh nodes as well other use cases such as indoor positioning and asset tracking. 

Key Features of Bluetooth mesh

Feature   Benefit
Mesh Node types   All the node types specified for Bluetooth mesh are supported on Silicon Labs stack: Relay, Proxy, Friend, and Low Power Node (LPN).
Provisioning Protocols   For new nodes on mesh network, the provisioner and provisioned node can communicate over either PB-ADV or PB-GATT bearers, ensuring compatibility for smartphones with Bluetooth LE and GATT support.
GATT Services   Both GATT services are supported in Silicon Labs Bluetooth mesh – Proxy and Provisioning.
Wi-Fi Coexistence   Allows the Bluetooth mesh device to coordinate transmitting and receiving with the collocated Wi-Fi device with reduced interference, and increased reliability.
Certificate Based Provisioning (CBP)   Use certificates to authenticate devices before provisioning, thus saving cost and time. Also, prevents counterfeit devices from being provisioned into the network.
Remote Provisioning (RPR)   Easy way to provision even when the nodes are not in direct radio range of the provisioner, thereby reducing installation cost and time.
Private Beacons   Does not allow for static information in beacons to be shared outside of the network.
Proprietary Extension   Allows extended advertising on all 40 channels - increasing throughput by 10x.
Simultaneous DFU Upgrade   Standardize way to do simultaneous DFU for homogeneous devices, reducing cost and time.
