Embodiment 1

[0036] Whether the SIG MESH network is through PB-ADV or GATT, three keys must be set for a single node: device key, network key and application key. The device key is a unique key for each node that is different from other nodes, and can be used to set some important attributes. The network key is used to connect the mesh between nodes, and the application key is used to authenticate whether the command received by the node needs to be executed. If the authentication fails, the command cannot be executed. Therefore, for a node, there may only be one device key, and this device key is only known by the node itself and the initiating node for networking. But nodes can have multiple network keys and application keys. Nodes in the same mesh network share the same network key and application key. Each node can send and listen to broadcast beacon packets and mesh beacon packets.

[0043] image 3 It is a schematic diagram of node networking in the present invention. Such as image 3 As shown, switch to the slave node in the MESH network and start sending a point-to-point communication networking request packet to the initiating node. The networking request packet includes the mac address of the slave node itself and the current network address of the slave node. In addition, the networking The request packet is encrypted on the slave node side using the generated network key and application key.

[0044] After the initiating node receives the networking request packet, it uses the network key and application key to analyze the networking request packet. In addition, when communicating between nodes in the mesh network, the generated network key and application key will be used for encryption and decryption. The initiating node saves the parsed mac address of the slave node locally, and reassigns a new network address for the slave node. The initiatin...

[0048] Figure 4 A schematic diagram of a method for networking the initiating node of the present invention, such as Figure 4 As shown, firstly, the initiating node broadcasts its own mac address and network address by broadcasting beacon packets; secondly, the initiating node receives the networking request packet sent by the slave node, which includes the slave node’s own mac address and the current Network address; then, the initiating node saves the received mac address of the slave node locally, and at the same time, generates and saves the device key of the slave node according to the obtained mac address of the slave node according to the device key generation method of SIG MESH; Finally, the initiating node assigns a unique network address for the entire mesh network to the slave node, and sends the network address to the slave node. So far, the networking process on the initiating node side ends.

Abstract

The invention relates to a Bluetooth SIGMESH fast networking method, comprising the following steps: broadcasting its own mac address and network address through a broadcast beacon packet by an initiating node; after listening to the broadcast beacon packet from the node, parsing the broadcast beacon packet, saving the mac address and the network address in the broadcast beacon packet, and forwarding the broadcast beacon packet to the surrounding node. The slave node generates a common network key and application key according to SIG MESH standard network key and application key generation algorithm by using the mac of the originating node. Switch from a node to a mesh network where network key and application key communicate under control The rapid networking method of the invention shortens networking time, reduces networking time cost and improves networking efficiency.

Description

technical field [0001] The invention belongs to the field of networking, and in particular relates to the field of rapid networking of bluetooth devices. Background technique [0002] With the introduction of the Bluetooth SIG MESH standard protocol, a relatively large number of Bluetooth nodes in general applications will become a common phenomenon. But the networking experience of Bluetooth cluster nodes is very poor. The two networking methods of SIG MESH (GATT, PB-ADV) can only be operated node by node, which is very inefficient. [0003] Bluetooth networking methods are divided into two networking methods: PB-ADV or GATT, but no matter which one needs to communicate multiple times one by one, if there are many nodes, it will obviously take a lot of time. In addition, because SIG MESH has made a lot of regulations on security, the whole process of networking is cumbersome and a lot of efficiency is sacrificed. Contents of the invention [0004] The object of the pre...
