FruityMesh is the reference implementation of the BlueRange initiative. It is the first open source implementation of a mesh network that is based on standard Bluetooth Low Energy 4.1 connections. In contrast to meshes that use advertising and scanning, this allows for a network run with battery powered devices. FruityMesh works with the Nordic nRF51 and nRF52 chipsets in combination with the S130/S132 SoftDevices and enables tons of devices to connect to each other with its auto-meshing capabilities.
