Detailed Description
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Firstly, it should be noted that, the networking method of the bluetooth low energy Mesh network provided by the embodiment of the present application is used to add a device to be networked into an existing Mesh network, and the existing Mesh network includes a network management device and at least two node devices (in this embodiment, the node devices refer to managed devices in the Mesh network in particular). The network management device may be an intelligent terminal with bluetooth function, such as a mobile phone, a tablet computer, a notebook computer, a cat fairy, a jail box, etc., and the managed device and the device to be network-connected may be bluetooth devices, such as an intelligent desk lamp, a sweeping robot, etc., which is not limited in this embodiment.
Referring to fig. 2, in an embodiment of the present application, a networking method of a bluetooth low energy Mesh network is provided, and the method is applied to a network management device, and specifically includes the following steps S201 to S204.
In step S201, the network management device sends a networking instruction to at least two node devices in the Mesh network, where the networking instruction is used to instruct the node device to add a device to be networked to the Mesh network.
In the step, after receiving the device adding instruction sent by the user, the network management device can send a networking instruction in a broadcast mode, so that all node devices in the Mesh network receive the networking instruction and enter a networking state. In addition, the network management device can also send a networking instruction to at least two node devices in the network through the Mesh network, so that the node devices enter a networking state. Of course, the networking instruction may also be sent to all node devices in the Mesh network, which is not limited in this embodiment.
For example, the networking instruction may be an ep_start_status (TRUE) message, which is used to instruct each node device that receives the instruction to set its state to ep_start_status=true, enter the networking state, and add the device to be networked to the Mesh network.
In step S202, the network management device receives the address checking message broadcast by the network access device.
Firstly, it should be noted that the address carried by the address checking message is the address of the device to be accessed in the Mesh network. In this embodiment, since the address is generated by the device to be network-connected, which may be the same as the addresses of other node devices in the Mesh network, there is a problem of address collision, and therefore, verification of the address is required. Thus, the device to be networked, after joining the Mesh network, broadcasts an address check message to determine if it conflicts with an existing address.
It should be noted that, in the process of broadcasting the address check message by the device to be accessed, since the network management device may not be in the radio frequency range, the address check message may need to be retransmitted through other node devices in the Mesh network, so that the network management device receives the address check message. In one example, each node device in the Mesh network, after receiving the address check message of the device to be accessed to the network, rebroadcasts the address check message, so that the network management device receives the address check message.
In one example, the address check message may be an ep_complete message, including status=ep_success message and Device UUID (Unique Universal Identification ) of the Device to be networked. The Device UUID is configured to uniquely indicate a corresponding Device to be network-connected, and carry an address to be checked. The status=ep_success message is used to indicate the successful network access of the corresponding device to be network-accessed.
If the network management device receives the address check message broadcast by the network access device within the first preset time, step S203 is executed, and timing is restarted.
Specifically, after sending the networking instruction, the network management device may locally set a timer with a duration of a first preset time, where the first preset time may be 3s, 5s, 10s, and so on, and specifically is determined according to a preset configuration. If the network management device receives the address verification message broadcast by the device to be accessed to the network within the first preset time, the network management device indicates that the device is accessing to the network, and at the moment, the network management device controls the timer to restart timing and executes the next step.
If the network management equipment does not receive the address verification message broadcast by any one of the devices to be accessed in the first preset time, all the devices to be accessed are considered to be accessed in the network, and at the moment, the network management equipment sends an ending instruction to the node equipment in the networking state so as to instruct the node equipment to stop adding the devices to be accessed in the Mesh network.
For example, the end instruction may be an ep_start_status (FALSE) message, and the end instruction is used to instruct the node device to set its Status to ep_start_status=false, and end networking. The sending modes of the ending instruction and the networking instruction are the same, and both include broadcast sending and direct sending through the Mesh network, specifically refer to the above, and the embodiment is not described herein.
In step S203, if the current node list of the network management device does not include the address of the device to be accessed, the address is added to the node list.
As an administrator of the Mesh network, the network management device typically maintains a node list, where characteristic information of each node device in the Mesh network is recorded, where the characteristic information includes an address of the node device. After receiving the address checking message broadcast by the network access equipment, the network management equipment can judge whether the current node list of the network management equipment comprises the address, if the current node list of the network management equipment does not comprise the address of the network access equipment, the network management equipment indicates that the address is unoccupied, and the address is added to the node list.
Step S204, if the current node list of the network management device includes the address of the device to be accessed, broadcasting an address conflict message of the device to be accessed.
If the current node list of the network management device comprises the address of the device to be accessed to the network, the address generated by the device to be accessed to the network is in conflict with the address of a certain node device in the Mesh network, and at the moment, the network management device broadcasts the address conflict message of the device to be accessed to the network. The ADDRESS collision message may be, for example, a status=ep_address_connect message.
And for the equipment to be accessed to the network, if the equipment to be accessed to the network does not receive the matched address conflict message within a third preset time, such as 1s, the address verification is successful. If the network equipment to be accessed receives the matched address conflict message within the third preset time, an address is regenerated, and the updated address check message is broadcast. The updated ADDRESS check message may be status=ep_address_read, for example.
It should be noted that, the address check message broadcast by the network access device carries a transaction code, and the transaction code value of the address check message broadcast later is greater than the transaction code value of the address check message broadcast earlier. For the address check message broadcast by the same device to be accessed to the network, the node device selects the address check message with the largest transaction code as the latest address check message after receiving the address check message, so as to avoid misoperation in the networking process.
Referring to fig. 3, the networking method of the bluetooth low energy Mesh network provided by the embodiment of the application is applied to at least two node devices in the Mesh network, and the networking method of each node device comprises the following steps S301-S303.
In step S301, the node device receives a networking instruction sent by the network management device.
The node device enters a group mesh state after receiving the group mesh state instruction. For example, the node apparatus sets its own state to ep_start_status=true after receiving the ep_start_status (TRUE) message, and starts scanning surrounding broadcast messages.
In addition, when the network management device sends the networking command in the form of broadcasting, since broadcasting generally has a certain radio frequency range, only the node devices in the radio frequency range can receive the networking command directly sent by the network management device. Therefore, after receiving the networking instruction, the node device needs to rebroadcast the networking instruction, so that all node devices in the Mesh network can receive the networking instruction.
For example, in the Mesh network shown in fig. 4, only node device a is set in the radio frequency range of the network management device, and node device B and node device C are set in the radio frequency range of the node device a. After receiving the networking instruction directly broadcast by the network management device, the node device A rebroadcasts the networking instruction, so that the node device B and the node device C can also receive the networking instruction.
When the network management device sends a networking instruction through the Mesh network, each node device in the at least two node devices can directly receive the networking instruction without forwarding.
Step S302, the node equipment adds the to-be-network-accessed equipment to the Mesh network.
Step S303, the node equipment receives an ending instruction sent by the network management equipment and stops adding the equipment to be accessed to the Mesh network.
The ending instruction is used for indicating the node equipment to stop adding the to-be-network-accessed equipment to the Mesh network. For example, when the node device receives an ep_start_status (FALSE) message, the state of itself is set to ep_start_status=false, and the addition of the device to be network-connected to the Mesh network is stopped.
Referring to fig. 5, in this embodiment, a method for adding a device to be network-connected to a Mesh network by a node device specifically includes the following steps S501-S504.
In step S501, the node device receives a non-network-access device beacon broadcast by the network-access device, where the non-network-access device beacon includes a unique device identifier of the network-access device.
During networking, the device to be networked will continuously broadcast unprovisioned device beacon, i.e., the non-networked device beacon, to inform surrounding node devices that it is ready to be networked. The beacon of the non-network-connected device comprises a unique device identifier of the device to be network-connected and is used for uniquely indicating the device to be network-connected. For example, the unique Device identification may be a Device UUID of the Device to be networked.
When a plurality of devices to be networked are prepared to be networked at the same time, the node device may receive beacons of non-networked devices broadcast by different devices to be networked. At this time, the node device can only select one non-network-access device beacon as a beacon to be processed, for example, one non-network-access device beacon received earliest in the current scanning process.
In step S502, the node device broadcasts a network access invitation message, where the network access invitation message includes a network identifier and a unique device identifier of the device to be accessed.
The node equipment analyzes the to-be-processed non-network-access equipment beacon, and obtains the unique equipment identifier carried by the non-network-access equipment beacon so as to determine the object to be invited to access the network. Then, the node device broadcasts a network access invitation message carrying the networking identifier and the unique device identifier, so as to invite the network access device corresponding to the unique device identifier to access the network.
The networking identifier is used for uniquely indicating a networking process between one node device and one device to be networked so as to ensure that the networking process is not interfered by other devices and keeps independence. The networking identification may be a 32bit random number, for example. The node device, after generating the networking identity, will store it locally and delete it after adding a successful or failed one to-be-networked device.
The device waiting to access the network can continuously scan surrounding broadcast messages in the process of waiting to access the network. In this embodiment, since there may be multiple devices to be logged in simultaneously, and at least two node devices add the devices to be logged in to the Mesh network simultaneously, the devices to be logged in may scan for the network access invitation messages broadcast by different node devices for inviting the same or different devices to be logged in. Therefore, after receiving each network access invitation message, the network access equipment needs to compare the unique equipment identifier carried by the network access invitation message with the unique equipment identifier of the network access equipment, and if the unique equipment identifier and the unique equipment identifier are the same, the invitation object of the network access invitation message is the network access equipment.
When there are a plurality of network access invitation messages of the network access equipment, the network access equipment can only select one of the network access invitation messages to process, such as the one of the network access invitation messages received earliest. Specifically, the device to be networked stores the networking identifier in the networking invitation information locally until the device to be networked is successfully added to the Mesh network or deleted after the addition fails. And broadcasting a network access response message carrying the networking identification to indicate that the network access is authorized.
In step S503, the node device receives a network access response message broadcasted by the network access device, where the network access response message includes a network identifier.
In order to avoid that the node device spends a long time waiting for the response of the device to be accessed to the network, and improve the networking efficiency, in one possible implementation manner, the node device needs to receive the network access response message broadcasted by the device to be accessed to the network within a second preset time, where the second preset time may be 300ms, 500ms, 800ms, and the like, and is specifically determined according to a preset configuration, and this embodiment is not limited. If the waiting time is out, the process goes to step S501 to re-receive the beacon of the non-network-connected device.
During the networking process, the node device may receive the network access response messages broadcast by different devices to be network accessed. Therefore, after receiving each network access response message, the node device needs to compare the network access identifier carried in the network access response message with the local network access identifier, and when the network access identifier and the local network access identifier are the same, the node device determines that the network access response message is a matched network access response message.
In step S504, the node device broadcasts a network access parameter, where the network access parameter carries a networking identifier.
After receiving the matched network access response message, the node equipment broadcasts network access parameters such as Net key carrying a networking identifier. After receiving the network access parameters, the network access equipment sets the network access parameters to the local and generates an address in the Mesh network so as to join the Mesh network.
It should be noted that, in the embodiment of the present application, the network management device, the node device and the device to be networked are all preset with the same application key and encryption and decryption rules, so as to encrypt and decrypt the information in the past, ensure the communication security in the networking process, and avoid information leakage.
According to the networking method of the low-power consumption Bluetooth Mesh network, when a plurality of to-be-networked devices are prepared to be networked at the same time, the network management device can control at least two node devices in the Mesh network to add the to-be-networked devices to the Mesh network at the same time, and the network management device only needs to check and manage addresses, so that networking efficiency of the low-power consumption Bluetooth Mesh network is remarkably improved.
