Mesh is a network topology used for establishing many-to-many (m:m) device communications. The mesh topology available on Bluetooth LE enables the creation of large-scale device networks and is ideally suited for control, monitoring, and automation systems where tens, hundreds, or thousands of devices need to reliably and securely communicate with one another.
Bluetooth Mesh was developed on the basis of low power consumption. It has five advantages over other protocols.
When Bluetooth mesh was designed, reliability and support for multicast operations involving groups of devices operating in harmony were top of the list of requirements (alongside others, such as security).
Bluetooth Mesh Lighting Features Bluetooth mesh is a full stack solution, spanning radio communications at the bottom of the stack and application-specific behaviors at the top. Lighting is regarded as an application in the world of Bluetooth mesh. By including features specifically for lighting systems, as well as other applications, Bluetooth meshis far more than just a wireless data communications system. It supports common lighting requirements “out of the box” and ensures interoperability across products from different vendors.
All mesh application behaviors are implemented using software modules known as models. A series of standard models have been defined by the Bluetooth SIG, and these are selected from to meet a product’s distinct requirements. This makes it easy for lighting products to include other non-lighting features, such as support for sensors, and for those features to work directly with the light’s primary features in a fully integrated manner, without the need for external controllers.
