nRF5 SDK for Mesh

Software Development Kit for Bluetooth mesh solutions using nRF51 Series and nRF52 Series
Active
Overview

Description

Nordic offers a complete solution for the Bluetooth mesh specification with the nRF5 SDK for Mesh and the nRF51 and nRF52 Series SoCs. It provides a powerful solution for product developers to take advantage of the new capabilities introduced by Bluetooth mesh. The nRF5 SDK for Mesh is intended to be used as a foundation for any Bluetooth mesh product development.

The addition of mesh networking capabilities to Bluetooth Low Energy enables extended range, increases the number of nodes and a many-to-many (m:m) communication topology. In a Bluetooth mesh network every received packet is broadcasted by relays, until the packet is received by the destination node (a so called managed flooding mesh.) A simple, but effective way of spreading information across the mesh network with no single point of failure. The mesh functionality is a significant update and enables new applications for Bluetooth in smart home, lighting, beaconing and asset tracking applications.
