ST Microelectronics – STSW-BNRG-Mesh
Mesh over Bluetooth Low Energy 
BlueNRG-Mesh is a solution for connecting multiple BLE (Bluetooth low energy) devices in Mesh networks for IoT (Internet of Things) solutions.
It enables the Bluetooth-enabled devices in powerful, integrated, range-extending Mesh networks with true two-way communication.
The solution contains the core functionality required to form a secure communication network and provides developers the flexibility they need to build applications.
The solution is compatible with the ST BlueNRG product family range.
