Mesh Your Smart Energy Devices over Bluetooth Low Energy

BlueNRG-Mesh from STMicroelectronics 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.

Applications include:

  • Smart home (lighting, HVAC, security and access control, healthcare)
  • Asset tracking
  • Assisted living
  • Smart meters
  • Smart city (street lighting, general purpose messaging)
