Bluetooth Mesh Networking
Bluetooth Mesh is a computer mesh networking standard based on Bluetooth Low Energy that allows for many-to-many communication over Bluetooth radio. The Bluetooth Mesh specifications were defined in the Mesh Profile and Mesh Model specifications by the Bluetooth Special Interest Group (Bluetooth SIG). Bluetooth Mesh was conceived in 2014 and adopted on . Overview Bluetooth Mesh is a mesh networking standard that operates on a flood network principle. It's based on the nodes relaying the messages: every relay node that receives a network packet that authenticates against a known network key that is not in message cache, that has a TTL ≥ 2 can be retransmitted with TTL = TTL - 1. Message caching is used to prevent relaying messages recently seen. Communication is carried in the messages that may be up to 384 bytes long, when using Segmentation and Reassembly (SAR) mechanism, but most of the messages fit in one segment, that is 11 bytes. Each message starts with an opcode, ...

Bluetooth Special Interest Group
The Bluetooth Special Interest Group (Bluetooth SIG) is the standards organization that oversees the development of Bluetooth standards and the licensing of the Bluetooth technologies and trademarks to manufacturers. The SIG is a not-for-profit, non-stock corporation founded in September 1998. The SIG is headquartered in Kirkland, Washington. The SIG does not make, manufacture or sell Bluetooth-enabled products. Introduction ''Bluetooth'' technology provides a way to exchange information between wireless devices such as PDAs, laptops, computers, printers and digital cameras via a secure, low-cost, globally available short-range radio frequency band. Originally developed by Ericsson, ''Bluetooth'' technology is now used in many different products by many different manufacturers. These manufacturers must be either Associate or Promoter members of(see below) the Bluetooth SIG before they are granted early access to the ''Bluetooth'' specifications, but published ''Blueto ...
