For Electronic devices to communicate and perform work efficiently networking is important. Bluetooth mesh networking is best solution for building automation sensor networks and other IoT solutions.
The new mesh capability enables many-to-many (m:m) device communications and is optimised for creating large-scale device networks. It is ideally suited for building automation sensor networks and other IoT solutions where tens hundreds or thousands of devices need to reliably and securely communicate with one another.
Today Bluetooth is the leading low power wireless connectivity technology used to stream audio transfer data or broadcast information between devices. Now with the introduction of a mesh networking capability Bluetooth mesh networking is poised to further catalyse beacons robotics industrial automation energy management smart city applications and other industrial IoT and advanced manufacturing solutions.
Bluetooth mesh is optimized for creating large-scale device networks and is ideally suited for building automation, sensor network and asset tracking solutions. Only Bluetooth mesh networking brings the proven, global interoperability and mature, trusted ecosystem associated with Bluetooth technology to the creation of industrial-grade device networks.
For message security every Bluetooth mesh network message is secured using NetKeys and AppKeys to encrypt and authenticate messages. NetKeys are used for the network layer communication. Assuming a Bluetooth mesh network has no subnets, all communication within that mesh network uses the same network key.
