  • BlueNRG-Mesh is a software solution for connecting multiple BLE (Bluetooth low energy) devices in Mesh networks for Internet of Things (IoT) solutions. It enables true two-way communication between Bluetooth-enabled devices in powerful, secure, integrated and range-extending Mesh networks.

    The solution is compatible with the ST BlueNRG product family range.

    Key Features

    • Mesh network with Bluetooth low energy (BLE) nodes enabling communication between a BLE device and a Smartphone
    • Control and monitor applications involving short packets
    • Advertising packets used for data communication using managed flooding method
    • Multi-hop data transmission up to 126 hops
    • Network node support up to 32,767 nodes
    • Multiple communication scenario
      • Smartphone to node communication with unicast addressing
      • Smartphone to node communication with multicast (Group) addressing
      • Smartphone to node communication with broadcast addressing
      • Node to node communication
    • Secure communication
      • Devices added to a network are provisioned using proven security algorithms using 256-bit elliptic curves
      • All messages in the network are encrypted with AES-128 CCM mode
      • Privacy through obfuscation
      • Protected against security attacks like Brute-force, Bit-Flipping, Eaves Dropping, Replay, Trashcan, Man in the middle and physical insecure device attacks
    • Supported features
      • Publish-subscribe paradigm (up to 10 groups)
