[0050] The exemplary embodiments will be described in detail herein below with reference to the drawings. When the following description refers to the drawings, identical numbers on different drawings represent the same or similar elements unless otherwise indicated. The following exemplary embodiments described in the exemplary embodiments are not representative of embodiments consistent with the present application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present application as detailed in the appended claims and not all embodiments. Other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative work are within the scope of protection of the present application.

[0051] First, the terms involved in the present application are explained:

[0052] Mesh network: also known as "multi-hop network", refers to a way of transmitting data and control instructions between network nodes through dynamic routing. This network can keep the connection between each node complete, when a node in the network topology fails or cannot serve, this architecture allows the use of "hopping" to form a new route to deliver messages to the transmission destination. Each node in the Mesh network must be configured after networking to ensure the security of the entire Mesh network.

[0053] MAC address: also known as LAN address, MAC address, Ethernet address or physical address, it is an address used to identify the location of network equipment. Each Bluetooth Mesh device corresponds to an address.

[0054] Mesh gateway: a network device with both Bluetooth communication capability and networking capability, which assists Bluetooth Mesh terminal devices in networking. The instructions issued by the cloud server will be issued to Bluetooth Mesh devices through the Mesh gateway, and the status of Bluetooth Mesh devices can also be reported to the cloud server through the Mesh gateway.

[0055] Bluetooth Mesh device: a terminal device that can access the Mesh network, has Bluetooth connection function, but does not have configuration function itself, and needs other devices with configuration function to start configuration, such as spotlight, downlight and other lighting devices.

[0056] Node: a connection point, representing a redistribution point or a communication endpoint (some terminal devices). The definition of node depends on the network and protocol layer mentioned. A physical network node is an active electronic device connected to the network, which can send, receive or forward information through communication channels.

[0057] Unicast address: used to identify a single interface, datagrams sent to a unicast address are delivered to the interface identified by the address. It is a necessary parameter of Bluetooth Mesh network, and has a unique interface address in Mesh network, which can identify an element in the node. The node is assigned when it accesses the network. A Mesh network can have 32767 unicast addresses.

[0058] Network ID: refers to the sign information of a machine in a network. For a specific machine, the IP address and MAC address of the machine are the signs in the network. Different layers have different signs in the network. The sign of the data link layer is the MAC address, the sign of the network layer is the IP address, and the sign of the transport layer is the port number of UDP or TCP.

[0059] IV index: refers to a 32-bit value shared by all nodes in the network. The purpose is to provide entropy (randomness) in the calculation of message random values.

[0060] Network Key: refers to the key used in the network.

[0061] application Key: that is, the attribute key commonly used, which can open a shortcut menu by pressing it.

[0062] Advertising Data (ADV): that is, the advertising data packet, which is the data transmitted to each node in the network communication by broadcasting. Broadcast information will cause a heavy burden to the network, because they require every host on the network to serve them, so the ability to send broadcast data packets is limited to those sockets explicitly marked as allowing broadcast. Since a datagram socket must be bound before broadcast can be used, all received broadcast messages have the sender's address and port.

[0063] Scan Response (SCAN_RSP): that is, the scan response after Bluetooth broadcast.

[0064] Universal Unique Identifier (UUID): a software construction standard composed of a group of 32-bit hexadecimal numbers. The purpose is to let all elements in the distributed system have unique identification information without the need for a central control terminal to specify the identification information.

[0065] PB-GATT: general attribute configuration bearer layer, usually used for server devices that do not support PB-ADV (devices that do not start configuration are added to the Mesh network through ADV, usually used for devices carrying the Mesh protocol stack), which uses proxy server and proxy client to exchange proxy PDU (Proxy PDU) to realize connection configuration.

[0066] Figure 1 The application scenario diagram of the method for accessing the Mesh network provided by the embodiments of the present application is shown in FIG. 1. Figure 1As shown, the user newly purchases a batch of Bluetooth Mesh devices 101 supporting Mesh networking, for example, spotlights. After the spotlights are installed on the wall, in order to facilitate subsequent remote intelligent control of each spotlight, it is necessary to configure the networking of the spotlights. Therefore, the first step is to configure the start of the spotlight. The start configuration is a secure process. After the start configuration, the device that has not been started will have a series of encryption keys, which can ensure the security and control accuracy of the information transmission process. The existing start configuration process usually triggers the spotlight on the same line to enter the configuration mode at the same time through continuous multiple on-off, but after entering, it still needs to be identified by the start configuration terminal 102, such as a tablet computer or a smart phone, to select and start the configuration of each spotlight. The specific Mesh network information is obtained from the cloud server 103 or the hardware server 104. The steps are complicated and the configuration time is long.

[0067] The method for accessing a Mesh network provided in the present application aims to solve the above technical problems of the prior art.

[0068] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific examples.

[0069] Figure 2 The method for accessing a Mesh network provided in the present application aims to solve the above technical problems of the prior art. Figure 2 As shown, a method for accessing a Mesh network comprises the following steps.

[0070] S201, receiving a broadcast message sent by a Bluetooth Mesh device, the broadcast message being used to indicate that the Bluetooth Mesh device is to be accessed to a Mesh network, and the broadcast message containing a MAC address of the Bluetooth Mesh device, the MAC address having a corresponding relationship with the Bluetooth Mesh device;

[0071] Specifically, the Bluetooth Mesh device sends a broadcast message to the surrounding devices through Bluetooth broadcast, indicating that the Bluetooth Mesh device is currently in a networking state, and at the same time, the identification information required for networking of the Bluetooth Mesh device, i.e. the MAC address, is broadcasted, so as to facilitate the start configuration terminal to perform networking configuration operation at the same time of receiving the broadcast message.

[0072] S202, obtaining a unicast address list according to the MAC address, the unicast address list storing the corresponding relationship between the MAC address of the Bluetooth Mesh device and the unicast address;

[0073] Specifically, after receiving the broadcast message, the Mesh gateway acquires the MAC address in the broadcast message according to the configuration state to be networked, and then judges the networking state of the Mesh gateway. When the Mesh gateway is connected with the cloud server, the unicast address list pre-stored in the cloud server is acquired, the unicast address list stores the correspondence between the MAC address and the unicast address, the corresponding unicast address is found according to the MAC address, if the corresponding relationship between the MAC address and the unicast address is not found in the cloud server, the cloud server allocates a unicast address according to the MAC address, and records the allocated unicast address and the MAC address in the unicast address list. When the Mesh gateway is not connected with the cloud server, that is, in the single-machine mode, the Mesh gateway allocates a unicast address according to the MAC address, and then records the allocated unicast address and the MAC address in the unicast address list.

[0074] S203, the unicast address list and the preset Mesh network parameter are sent to the Bluetooth Mesh device to be accessed to the Mesh network through Bluetooth broadcast.

[0075] Specifically, after the unicast address list is acquired, the preset Mesh network parameter and the unicast address list are packaged, and then broadcasted to all Bluetooth Mesh devices through Bluetooth broadcast. After the Bluetooth Mesh device receives the preset Mesh network parameter and the unicast address list, the unicast address corresponding to the MAC address of the Bluetooth Mesh device is found from the unicast address list, and then the Bluetooth Mesh device accesses the Mesh network according to the unicast address and the preset Mesh network parameter.

[0076] The method provided in the embodiment receives the broadcast message sent by the Bluetooth Mesh device, the broadcast message is used to indicate that the Bluetooth Mesh device is to be accessed to the Mesh network, the broadcast message contains the MAC address of the Bluetooth Mesh device, the MAC address has a corresponding relationship with the Bluetooth Mesh device, the unicast address list is obtained according to the MAC address, the unicast address list stores the corresponding relationship between the MAC address of the Bluetooth Mesh device and the unicast address, and the unicast address list and the preset Mesh network parameter are sent to the Bluetooth Mesh device to be accessed to the Mesh network through Bluetooth broadcast. The method reduces the network configuration step of manual operation of the user, is simple and convenient, improves the network configuration speed, improves the user experience, has high network configuration stability, and realizes the automatic configuration function of multiple Mesh nodes.

[0077] The method for accessing the Mesh network according to the present application will be described in detail in combination with a specific embodiment.

[0078] Figure 3 The method for accessing the Mesh network provided in Embodiment Two of the present application is shown in a flowchart. As shown in the figure, the method comprises the following steps. Figure 3 ​

[0079] S301, receiving a broadcast message sent by a Bluetooth Mesh device, the broadcast message being used to indicate that the Bluetooth Mesh device is to be accessed into a Mesh network, the broadcast message containing a MAC address of the Bluetooth Mesh device, the MAC address being in a corresponding relationship with the Bluetooth Mesh device;

[0080] The implementation manner of S301 is similar to the implementation manner of S201, and details are not described herein.

[0081] S302, configuring a unicast address according to each MAC address;

[0082] S303, if the Mesh gateway has connected a cloud server, obtaining a unicast address allocated by the cloud server from the cloud server;

[0083] S304, if the Mesh gateway has not connected the cloud server, the Mesh gateway directly allocates a unicast address;

[0084] S305, obtaining a unicast address list according to the MAC address and the corresponding unicast address;

[0085] Specifically, since one Mesh network can have 32767 unicast addresses, the unicast address range corresponding to the cloud server and the unicast address range corresponding to the Mesh gateway are pre-allocated, so as to avoid the repetition phenomenon of the two when the unicast addresses are specified. Since the cloud server can carry more configuration devices and can share network information, in the case of connecting the cloud server, the unicast address corresponding to the cloud server is preferentially selected, and the unicast address matched with the MAC address is first obtained from the correspondence table of the MAC address and the unicast address pre-stored in the cloud server. If the MAC address does not correspond to the allocated unicast address, the cloud server allocates a new unicast address according to the MAC address, and stores the correspondence between the unicast address and the MAC address in the correspondence table. When there is no connection to the cloud server, the Mesh gateway allocates a unicast address for the node, which is also uniquely allocated based on the MAC address, and records the correspondence between the unicast address and the MAC address. The correspondence between the unicast address and the MAC address of the Bluetooth Mesh device to be configured in the network obtained by allocation or direct acquisition is integrated to obtain a unicast address list.

[0086] S306, sending the unicast address list and preset Mesh network parameters to the Bluetooth Mesh device to be accessed into the Mesh network through Bluetooth broadcast.

[0087] Specifically, the preset Mesh network parameters include Network ID, IV index, Network Key, application Key and other Mesh network parameters, the unicast address list and the preset Mesh network parameters jointly constitute Mesh configuration information, after the Mesh gateway acquires the Mesh configuration information, needs to send a Bluetooth broadcast at an agreed UUID, and needs to broadcast the encrypted Mesh configuration information, the encryption method adopts RC4 or AES-128 algorithm, the encryption Key is generated according to the MAC address, the Mesh configuration information is respectively contained in the broadcast packet (Advertising Data) and the response packet (Scan Response), when the length of the encrypted Network ID, IV index, Network Key, application Key, MAC, Unicast Address and other Mesh network parameters is too long, the Data length of the broadcast packet (Advertising Data) and the response packet (Scan Response) is not enough, the multiple broadcast packets can be sent in turn, then the packet header must contain the field length, the packet number, to facilitate subsequent packet grouping.

[0088] The format of the broadcast packet and the response packet is as follows:

[0089]

[0090] In the table, Service UUID: custom UUID, for example 0xFF01.

[0091] CID (Company Identifiers): company identifier, for example 0x0123.

[0092] The Service Header is defined as follows:

[0093]

[0094] In the table, message ID: configuration message length, one configuration information can be sent in N packets, each time a complete configuration information is sent as a round, the message ID of each broadcast packet in a round remains unique.

[0095] Data encryption indication: determines whether the sent Service Data is encrypted, 1: encrypted; 0: not encrypted.

[0096] Version information: a value between 0-7.

[0097] Service Header Byte 1: frame number and frame sequence number, as follows:

[0098]

[0099] Frame Number: If one configuration information is split into multiple frames, the Service Data following one ADV or SCAN_RSP is one frame.

[0100] Total unpacked frame number: If one configuration information is split into 4 frames, 2 groups of different ADV and SCAN_RSP need to be broadcasted.

[0101] Service Header Byte 2: Total length of frame data. Length is 0-250.

[0102] Total length of frame data: that is, the total length of configuration message.

[0103] The format of Mesh network configuration information carried in Service Data is as follows:

[0104]

[0105]

[0106] The structure of NetworkKey is as follows:

[0107] 1 NETWORK_INDEX Short 2 Network Key Index 2 NETWORK_KEY Char 16 Network Key

[0108] The structure of ApplicationKey is as follows:

[0109] 1 APPLICATION_KEY_INDEX Short 2 Application Key Index 2 NETWORK_INDEX Short 2 Network Key Index 3 APPLICATION_KEY_KEY Char 16 Application Key

[0110] ElementAddress structure, each scanned device is allocated a Unicast address, as follows:

[0111]

[0112] The method provided by the embodiment receives a broadcast message sent by a Bluetooth Mesh device, the broadcast message is used to indicate that the Bluetooth Mesh device is to be accessed to a Mesh network, the broadcast message contains a MAC address of the Bluetooth Mesh device, the MAC address has a corresponding relationship with the Bluetooth Mesh device, a unicast address is configured according to each MAC address, if a Mesh gateway has connected a cloud server, a unicast address allocated by the cloud server is obtained from the cloud server, if the Mesh gateway has not connected the cloud server, the Mesh gateway directly allocates a unicast address, a unicast address list is obtained according to the MAC address and the corresponding unicast address, and the unicast address list and preset Mesh network parameters are sent to the Bluetooth Mesh device to be accessed to the Mesh network through Bluetooth broadcast, so that the process that the network device controls the Bluetooth Mesh device to access to the Mesh network is realized, manual intervention is not needed during the process, tedious operation of a user is avoided, and user experience is improved.

[0113] Figure 4 The method flowchart for accessing to a Mesh network provided by the third embodiment of the application is shown in FIG. 3. Figure 4 The method includes the following steps.

[0114] S401, if no configuration information sent by a start configuration terminal is obtained within a preset time range, a broadcast message is sent to a Mesh gateway;

[0115] Specifically, after the Bluetooth Mesh device sends the broadcast message to be connected to a network, the Bluetooth Mesh device waits for a start configuration terminal to identify the network configuration within a preset broadcast configuration time range, for example, the PB-GATT configuration message of a mobile phone is obtained within 30 seconds of broadcast, if the PB-GATT configuration message of the mobile phone is not obtained within 30 seconds, the Bluetooth Mesh device enters a broadcast scanning stage, sends a broadcast message to a Mesh gateway, and waits for scanning configuration information broadcast by the Mesh gateway.

[0116] S402, a broadcast message is sent to a Mesh gateway, the broadcast message is used to indicate that a Bluetooth Mesh device is to be accessed to a Mesh network, the broadcast message contains a MAC address of the Bluetooth Mesh device, and the MAC address has a corresponding relationship with the Bluetooth Mesh device;

[0117] Specifically, the Bluetooth Mesh device sends a broadcast message to a Mesh gateway through Bluetooth broadcast, broadcasts the identification information required for the Bluetooth Mesh device to be connected to a network, that is, a MAC address, so that a start configuration terminal can execute a network connection configuration operation at the same time when the broadcast message is received.

[0118] S403, preset Mesh network parameters and a unicast address list sent by the Mesh gateway are obtained;

[0119] Specifically, the correspondence between the MAC address and the unicast address is stored in the unicast address list, each unicast address is allocated by the Mesh gateway or obtained from the cloud server by the Mesh gateway, and the unicast address corresponds to the Bluetooth Mesh device uniquely, thereby ensuring the implementation of the networking transmission function.

[0120] S404, according to the preset Mesh network parameter and the unicast address list, join the Mesh network, the unicast address list stores the correspondence between the MAC address of the Bluetooth Mesh device and the unicast address;

[0121] Specifically, since the Mesh gateway sends the Mesh configuration information in a broadcast manner, all devices can obtain it, and the Mesh gateway needs to send it in an encrypted manner to ensure the security of the information, therefore, after the Bluetooth Mesh device scans the broadcast, it is found that the UUID configuration broadcast format is agreed, the broadcast information is received, the agreed packet protocol is packaged, and all encrypted Mesh configuration information is obtained. The Mesh Dev Key is generated according to the device itself MAC according to the encryption algorithm, such as: the first 16 bytes of SHA256 of the device MAC, after the Mesh configuration information is decrypted, the Bluetooth Mesh device first finds the unicast address corresponding to the device itself MAC address in the unicast address list, then combines the found unicast address and the preset Mesh network parameter to obtain the Mesh configuration information for networking, and joins the network according to the Mesh configuration information. If the Bluetooth Mesh device cannot scan the broadcast and also cannot obtain the PB-GATT configuration message of the mobile phone, after exceeding the preset scanning broadcast time threshold, the Bluetooth Mesh device exits the configuration mode. Further, if the Bluetooth Mesh device fails to decrypt successfully or fails to access the network, it returns to the initial scanning broadcast state to perform the scanning operation again, the number of returns can be preset, and after exceeding the number of returns, the configuration mode is exited, the normal working state is executed, and after the normal working state reaches the preset working time threshold, the historical return number is cleared, and the broadcast configuration can be started again, thereby avoiding the unauthorized device from joining the Mesh network.

[0122] S405, if the configuration information sent by the start configuration terminal is obtained within a preset time range, then access the Mesh network according to the configuration information sent by the start configuration terminal;

[0123] Specifically, after the Bluetooth Mesh device sends the broadcast message to be networked, it waits for the start configuration terminal to identify the network configuration within the preset broadcast configuration time range, for example, acquires the PB-GATT configuration message of the mobile phone within 30 seconds of broadcasting, and the PB-GATT configuration message of the mobile phone contains the Mesh configuration information required by the Bluetooth Mesh device for networking, such as Network ID, Unicast Address, IVindex, Network Key, application Key, MAC, Unicast Address, etc., and the Bluetooth Mesh device joins the Mesh network according to the Mesh configuration information.

[0124] S406, broadcast state information in the Mesh network, the state information being used to indicate that the Bluetooth Mesh device successfully accesses the Mesh network.

[0125] Specifically, after the Bluetooth Mesh device successfully joins the Mesh network, it exits the configuration mode and broadcasts the state information that it has successfully networked in the Mesh network to all nodes, thereby improving the integrity and stability of the Mesh network.

[0126] The method provided in the embodiment, if no configuration information sent by the start configuration terminal is acquired within the preset time range, a broadcast message is sent to the Mesh gateway; the broadcast message is used to indicate that the Bluetooth Mesh device is to access the Mesh network, and the broadcast message contains the MAC address of the Bluetooth Mesh device, the MAC address and the Bluetooth Mesh device have a corresponding relationship; preset Mesh network parameters and a unicast address list sent by the Mesh gateway are acquired; the Bluetooth Mesh device joins the Mesh network according to the preset Mesh network parameters and the unicast address list, the unicast address list stores the corresponding relationship between the MAC address of the Bluetooth Mesh device and the unicast address; if the configuration information sent by the start configuration terminal is acquired within the preset time range, the Bluetooth Mesh device accesses the Mesh network according to the configuration information sent by the start configuration terminal; state information is broadcast in the Mesh network, the state information is used to indicate that the Bluetooth Mesh device successfully accesses the Mesh network, the process of automatically accessing the Mesh network by the terminal device is realized, the data information transmission process is encrypted, unauthorized devices are prevented from mistakenly entering the network, batch configuration networking is realized by broadcasting, Bluetooth transmission ensures the stability of networking, and the convenience and speed of network configuration are improved.
