Co to jest Bluetooth Mesh Networking?

Bluetooth Mesh is a network topology defined by Bluetooth Special Interest Group (SIG) that enables many- to-many (m: m) communicaton among Bluetooth Lowergy (BLE) devices. Unlike traditional Bluetooth point - to -point (p2p) connections, where one device talks directly to another, a mesh network allows any device with in range te relay messages to devices, for ming a sel- heating, scale web nof nodes.

Advantages Over Traditional Wireless Networks

Commercial buildings today use a variety of wireless protocles: Wi-Fi, Zigbee, Z-Wave, Thread, and publicary sub-GHz solutions. Bluetooth Mesh offers distinct providents that make it a strong candidate for large-scale IoT.

Setting up a Bluetooth Mesh network requires no central coordinator or gateway infrastructure. Devices are provisioned using a smartphone app or commissioning tool that scans QR codes on the nodes. The network self-organises as devices are added. This plug-and-play approach dramatically reduces installation labor, especially in retrofit where where running new cables is coprisive.
