Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the appended claims, and not all embodiments. Other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without any creative effort, shall fall within the protection scope of the present invention.
First, terms related to the present application are explained:
mesh network: also known as a "multihop network," refers to a network in which data and control commands are transmitted between network nodes by dynamic routing. The network can keep the connection between each node complete, when a certain node in the network topology fails or cannot serve, the architecture allows a new route to be formed by using a 'jumping' mode and then the message is sent to a transmission destination, and each node in the Mesh network needs to be configured and then networked, so that the overall safety of the Mesh network is ensured.
MAC address: namely a Media Access Control Address (MAC Address), also called local area network Address (LAN Address), MAC Address, ethernet Address or Physical Address, which is an Address used to identify the location of the network device, one Address for each bluetooth Mesh device.
And (4) Mesh gateway: the Bluetooth Mesh terminal device has the Bluetooth communication capacity and the networking capacity, assists a network device networked by the Bluetooth Mesh terminal device, a command issued by the cloud server can be issued to the Bluetooth Mesh device through the Mesh gateway, and the state of the Bluetooth Mesh device can be reported to the cloud server through the Mesh gateway.
Bluetooth Mesh equipment: the terminal device capable of accessing the Mesh network has a bluetooth connection function, but does not have a configuration function, and needs other devices having the configuration function to start and configure the terminal device, such as a spotlight, a down lamp and other lighting devices.
Node (node): is a connection point, representing a redistribution point (redistribution point) or a communication end point (some end devices). The definition of the nodes depends on the mentioned network and protocol layers. A physical network node is an active electronic device connected to a network and capable of sending, receiving or forwarding information over a communication channel.
Unicast Address (Unicast Address): for identifying a single interface, datagrams sent to a unicast address are delivered to the interface identified by the address. Is a necessary parameter of the bluetooth Mesh network, and has a unique interface address in the Mesh network, which can identify an element in a node, and the node is allocated to obtain when accessing the network. A Mesh network may have 32767 unicast addresses.
Network identification (Network ID): the identifier is the identifier information of a machine in a network, for a specific machine, the IP address and the MAC address of the machine are identified in the network, different layers in the network have different identifiers, the identifier of a data link layer is the MAC address, the identifier of a network layer is the IP address, and the identifier of a transmission layer is the port number of UDP or TCP.
Initialization vector index (IV index): refers to a 32-bit value that is shared by all nodes in the network. The purpose of this is to provide entropy (randomness) in the computation of message random values.
Network Key (Network Key): refers to a key used in the network.
Application Key (application Key): i.e. the usual attribute key, which can be pressed to open a shortcut menu.
Broadcast packet (ADV): namely, broadcast packets, are data transmitted to each node in a broadcast manner in network communication. Broadcast messages can be extremely burdensome on the network because they require every host on the network to service them, so the ability to send broadcast packets is limited to those sockets that are explicitly labeled as being allowed to be broadcast, and since one datagram socket must be bundled before broadcast is used, all broadcast messages received carry the sender's address and port.
Response packet (Scan Response, scan _ RSP): i.e. a scan response after a bluetooth broadcast.
Universal Unique Identifier (UUID): is a standard for software construction, consisting of a set of 32-bit 16-ary digits. The aim is to make all elements in the distributed system have unique identification information without the need of specifying the identification information through a central control end.
PB-GATT: the generic attribute configuration bearer layer is generally used for a server device that does not support PB-ADV (devices that do not start configuration are added to a Mesh network and are mostly used for devices carrying a Mesh protocol stack in an ADV bearer manner), and connection configuration is implemented by exchanging Proxy configuration protocol data units (Proxy PDUs) between a Proxy server and a Proxy client.

specifically, since the Mesh gateway is the Mesh configuration information sent in a broadcast manner, all devices can acquire the Mesh configuration information, and the Mesh gateway needs to send the information in an encrypted manner to ensure the security of the information, after the bluetooth Mesh device scans the broadcast, the bluetooth Mesh device receives the broadcast information and obtains all encrypted Mesh configuration information according to an agreed packet protocol packet. The Mesh Dev Key is generated by the device according to the MAC and the encryption algorithm, such as: the device MAC is the first 16 bytes of SHA256, after the Mesh configuration information is decrypted, the Bluetooth Mesh device firstly finds a unicast address corresponding to the device MAC address from a unicast address list, then combines the found unicast address with the preset Mesh network parameters to obtain the Mesh configuration information for networking, and joins the network according to the Mesh configuration information. If the Bluetooth Mesh equipment cannot scan the broadcast and does not acquire the PB-GATT configuration message of the mobile phone, the Bluetooth Mesh equipment exits the configuration mode after the preset scanning broadcast duration threshold value is exceeded.
