![]() Mesh networks dynamically self-organize and self-configure, which can reduce installation overhead. This lack of dependency on one node allows for every node to participate in the relay of information. bridges, switches and other infrastructure devices) connect directly, dynamically and non-hierarchically to as many other nodes as possible and cooperate with one another to efficiently route data from/to clients. Figure 1: BLE topologiesįrom Wikipedia’s page on mesh networking:Ī mesh network is a local network topology in which the infrastructure nodes (i.e. ![]() Devices can now operate in a many-to-many topology, or what’s called mesh, where devices can set up connections with multiple other devices within the network. With Bluetooth mesh, a new topology is introduced for BLE. One-to-many: when BLE devices operate exclusively in the Broadcast state, such as Beacons.One-to-one: when two BLE devices are connected.The Bluetooth mesh specification was released in July of 2017 with the goal of increasing the range of Bluetooth networks and adding support for more industrial applications that utilize BLE.Įarlier versions of Bluetooth supported two different topologies: The maximum hops a message can travel within a Bluetooth mesh network (defined in version 1.0 of the specification) is 127 hops.The maximum number of nodes within a Bluetooth mesh network (defined in version 1.0 of the specification) is 32,767 nodes. ![]()
