Problems solved by technology
[0002] The Bluetooth Mesh network is a network topology with a mesh structure. Each node performs multi-hop transmission through forwarding. The network uses Netkey to isolate each network. The number of nodes supported in theory reaches 32,767, but in In actual use, it is found that with the increase of the number of nodes, the degree of network congestion rises sharply, resulting in increased network delay and poor user experience

Embodiment 1
[0028] The embodiment of the present invention provides a Bluetooth MESH different network data transmission method, the method is: build a bridging node in the Bluetooth MESH network, when the node where the network information originator accesses the network and the target node where the information receiver is located are not in the same When connecting to a network, the information is forwarded through the bridging node that bridges the two networks.
[0029] In this embodiment, a new node role is proposed, that is, a bridge node, which has the following characteristics:
[0030] a) Support multiple NETKEY and APPKEY;
[0031] b) Support APPKEY binding to multiple NETKEYs;
[0032] c) have specific identification characteristics, such as OOB characteristics or special UUID;
[0033] d) Support data transmission in the network of the self-defined private format data in this embodiment, that is, Vendor Models.
[0034] The provisioning process of bridge nodes is roughly t...

The invention relates to a method for transmitting data in different networks of Bluetooth MESH, which includes: constructing a bridging node in the Bluetooth MESH network, when the node where the network information originator accesses the network and the target node where the information receiver is located are not in the same network , to forward information by bridging the bridging nodes of the two networks. The present invention realizes the communication between subnets through bridging. By dividing a large network into multiple networks, the communication in each subnet does not interfere with each other. At the same time, cross-network communication can be realized, which greatly reduces the network load. Improve the network response speed and solve the problems of high network load and serious delay caused by the excessive number of nodes in the traditional Bluetooth Mesh network. Moreover, due to the existence of bridging nodes, the fusion control of multiple different networks and the broadcast control become very convenient.
Description
technical field [0001] The invention relates to the field of bluetooth network communication, in particular to a data transmission method of different bluetooth MESH networks. Background technique [0002] The Bluetooth Mesh network is a network topology with a mesh structure. Its nodes perform multi-hop transmission through forwarding. Netkey is used in the network to isolate each network. The number of nodes it supports theoretically reaches 32,767, but in In practical application, it is found that as the number of nodes increases, the degree of network congestion increases sharply, resulting in increased network delay and poor user experience. Contents of the invention [0003] In order to solve the above problems, the present invention proposes a data transmission method of Bluetooth MESH in different networks. [0004] The specific plan is as follows: [0005] A Bluetooth MESH different network data transmission method, comprising: constructing a bridging node in th...
