BLE Mesh is designed for networks supporting large-scale node communication. It can support more nodes communicating over longer message transmission distances (relay nodes), lower power consumption IoT nodes (low power nodes), and reliable message transmission (secure encryption). For instance, BLE Mesh nodes can be deployed in scenarios like parking lots, building automation, and indoor supermarkets, achieving secure and reliable data interaction through the inherent characteristics of Mesh.
The goal of BLE Mesh is a trusted and secure network with full interoperability, a mature ecosystem, and the ability to meet industrial-grade applications while supporting large-scale node networking.
