Feasycom BLE Mesh is a communication capability used for establishing multi-to-multi (m:m) device transmission, network coverage, and for Bluetooth Low Energy (BLE). It utilizes a tree topology network with nodes that possess various SIG-MESH functions. It does not require a central node and uses the publish/subscribe model for communication to deploy nodes in a one-to-many or multi-to-many manner. Based on this network topology, it can be expanded to tens of thousands of nodes, allowing devices to transmit in a reliable and secure environment as an Internet of Things (IoT) solution.
