Mesh Networking

Bluetooth mesh network communication

The mesh networking capabilities of Bluetooth® Toolbox enable you to create a Bluetooth mesh network and realize mesh packet communication.

Use the features and reference examples to:

  • Simulate and visualize a Bluetooth mesh network over an advertising bearer, consisting of relay, low power, and friend nodes with varying multiple source and destination nodes.

  • Analyze mesh packet communication and compute energy consumption of nodes in the transmission, listen, sleep, and idle states.

  • Simulate managed flooding and visualize the flow of packets.
