FIG. 1 is a flow chart of the present invention.
Detailed Description
The invention is further described below by means of specific embodiments.
Referring to fig. 1, a BLE MESH-based intelligent device network distribution method is used for adding a device to a network, where the device may be a bulb, a gateway, a switch, a sensor, a remote controller, or the like, and the intelligent device has a communication module, and the communication module is a bluetooth module, and may be a WIFI module, a ZigBee module, or other common communication modules as needed. The distribution network (provision) of the invention can be an intelligent terminal or a monitoring terminal, and the like, and also has a communication module, for example, the intelligent terminal is a mobile phone, an IPAD, and the like.
The method of the invention comprises the following steps:
1) the device sends out a beacon without a network distribution. Specifically, when the device is powered on, and is in the non-distribution network mode, a non-distribution network beacon (beacon) is sent out, where the non-distribution network beacon includes basic information of the device, such as, but not limited to, a UUID, a device name, and a mac address.
2) The network distribution person scans the beacon of the device without the network distribution through the Bluetooth, and the user selects the device to carry out network distribution.
3) And the distribution network user sets the node role of the equipment, sends the first network key and the request DCD data to the equipment, restarts the equipment if the return value is wrong, returns to the step 2), and enters the step 4) if the return value is correct.
Specifically, the node role includes, but is not limited to, a light bulb, a gateway, a switch, a sensor, a remote controller, and the like. The distribution network person sends a first network key (netkey) to the device by means of the GATT, and the first network key is used for encrypting the network. The distribution network operator also requests the DCD data from the device to obtain a model list, which is a list of functions of the device, such as, but not limited to, dimming, switching, etc.
The distribution network user also receives a return value after sending the information, and if the return value is wrong, such as a timeout error, an analysis error or a verification error, the distribution network user sends a restart instruction to the equipment through the GATT so as to restart the equipment, and then, the step 2) is returned. And if the return value is correct, entering the next step. The restart instruction of the present invention may be a custom restart instruction, but is not limited thereto.
4) And the network distributor sends a second network key to the equipment, binds the second network key with the acquired DCD data, restarts the equipment if the return value is wrong, and returns to the step 2), wherein the equipment can store the reason of the failure of the distribution network. And when the return value is correct, entering the step 5).
Specifically, the network distributor may send a second network KEY (proxy KEY) to the device by way of GATT, where the second network KEY is also used to encrypt the network, which is used as a second layer encryption of the network. The first network key and the second network key of the present invention may be two keys defined by sig mesh protocol, which are both a series of ciphertext keys used for encrypting different layers, but are not limited thereto. The distribution network further binds the second network key to the obtained model list. In this step, after the distribution network user sends the information, the distribution network user also receives a return value, and if the return value is wrong, such as a timeout error, an analysis error, a verification error, or the like, but not limited thereto, the distribution network user sends a restart instruction to the device through the GATT to restart the device, and returns to step 2), and the device stores the reason for the distribution network failure. And if the return value is correct, entering the next step.
5) And the distribution network user sets the subscription address and the release address of the node role and sends the subscription address and the release address to the equipment. The subscription address and the distribution address are the message publishing address, the message receiving address and the like.
6) And when the distribution network is successful, the equipment receives information including a first network key, a second network key, a subscription address, a release address and the like, namely successfully joins the network, and completes the distribution network.
By adopting the method, after the distribution network failure occurs in the distribution network process, the equipment of the distributed network does not need to be manually operated again, can automatically recover to the state of the distribution network, and can save complex operation. If a plurality of BLE equipment wait for when joining in marriage the net together, can accurate selection join in marriage net target, the operation is succinct, effectively improves and joins in marriage net success rate.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
