The Bluetooth MESH network is a low-power Bluetooth network topology used to establish many-to-many device communication, and the devices can transmit information and data to each other. In the Bluetooth MESH network, the devices that have not joined the Bluetooth MESH network are usually called unprovisioned network devices, and the unprovisioned network devices are called nodes after joining the Bluetooth MESH network.

The nodes in the Mesh network can be classified into various applications such as sensors, lamps, gateways, and repeaters according to their application functions. It is in a long-term dormant state, and needs to establish a friendship relationship with the always-on equipment and process network information regularly, so it cannot monitor adv packets for a long time. In the present invention, the node adopts a constant electric node, that is, a non-low power consumption node.

A passive wireless switch control method based on a Bluetooth MESH network of the present invention at least includes network access binding and control distribution, specifically as follows:

Network access binding: select at least one node of the Bluetooth MESH network as the monitoring node, the monitoring node listens to the adv packet broadcast by the passive wireless switch, analyzes and stores it, and the monitoring node also stores configuration information.

Specifically, the so-called network access binding in the present invention refers to setting one or more nodes in the Bluetooth Mesh network to listen to the adv packets broadcast by the passive wireless switch. The adv package is usually a type of non-connectable custom adv package, and the following types of information can be obtained after parsing: MAC address, device identification type code, manufacturer identification code, key code and other information. The listening node stores configuration information matched with the adv package, wherein the configuration information is that the configuration information associated with the passive wireless switch and the actual control operation is a translation rule, which may include an operation identification code (that is, each button of the passive wireless switch corresponding adv), response target range (such as a single device or multiple devices or a logical group), response actions (such as turning on the light or adjusting to 60% brightness) and additional operations of the response (such as delayed response time, response operation fade time wait). When the monitoring node listens to the ADV packet of the passive wireless switch, it analyzes it. If the parsed MAC address, device identification type code, manufacturer identification code, and key code match the stored configuration information, the rules for subsequent translation steps.

The number of buttons of a passive wireless switch is determined according to its physical structure, and there may be one or more. The specific functions of the buttons are configured through configuration information and can be customized. When the passive wireless switch joins the Bluetooth MESH network for the first time, the configuration information stored by the monitoring node is the default configuration information, and the button function is the default function.

When network access binding is required, the selected listening node needs an operation to trigger the binding. The triggering binding operation includes but is not limited to: triggering the physical button on the listening node, the operation button on the App, or power-on, etc. After the monitoring node triggers the binding operation, the monitoring node will perform a search operation within a preset time period to monitor the passive wireless switch. At this time, the passive wireless switch performs a network access operation. The network access operation can be to press at least one designated button of the passive wireless switch (for example, press two designated buttons at the same time to avoid accidental touch), then the passive wireless switch will send out adv package. The listening node receives the adv packet for parsing and storage. The monitoring node can also remind the user that the network access binding is completed by flashing lights, reporting to the App for pop-up windows, changing brightness or color, etc.

Control distribution: the listening node receives and analyzes the adv packet broadcast by the passive wireless switch, translates the stored configuration information to obtain the Bluetooth MESH data packet, and forwards the Bluetooth MESH data packet in the Bluetooth MESH network, and the non-target device receives the Bluetooth MESH data After the packet is forwarded, the target device responds to the action after receiving the Bluetooth MESH packet.

Control distribution refers to how the target device receives and responds when the passive wireless switch is pressed. In the control distribution, the listening node also listens to the adv packet broadcast by the control operation of the passive wireless switch. The control operation may be pressing a certain button on the passive wireless switch. The adv packet broadcast by the passive wireless switch in the control distribution and the adv packet broadcast in the network access binding may contain the same data type, but the specific content may be different.

Specifically, when the user presses a button of the passive wireless switch that has been bound to the network, the passive wireless switch will send an adv packet, and the monitoring node will receive and successfully parse the adv packet, and translate it according to the stored configuration information Get the Bluetooth MESH packet and forward it in the Bluetooth Mesh network. The format of the forwarded Bluetooth MESH packet is completely in the Bluetooth Mesh format, including the general SIG Model and the customized Vendor model. Relying on the complete security and reliability of the Bluetooth Mesh network, the target device can stably receive and respond to corresponding actions. The target device can be a single device or multiple devices or a logical group. Logical groups usually refer to nodes that are in the same location or need to be controlled together. All the spotlights in the corridor can also be set to a logical group, and the same light (node) can be in multiple groups at the same time. Refer to FIG. 1 , which is a schematic diagram of a data path for a user to control the controlled devices of the first logic group through a passive wireless switch.

In the present invention, for the listening node, under different trigger modes, the response after receiving the adv packet broadcast by the passive wireless switch is different. In the network access binding, the monitoring adv packet is for discovering and identifying the specified passive panel, and save its characteristic values in the monitoring node for subsequent user configuration; and in the distribution control stage, when the adv package is monitored, corresponding operations such as translation and forwarding must be performed according to the stored configuration information.

If the configuration information stored in the monitoring node is the default configuration information, the default translation rules set by the device factory will be used, such as short press to switch lights, long press to dim, etc. In practical applications, the configuration information can be modified, that is, the translation rules can be customized. When the user needs to change the function of the button, or needs to select the number and range of the controlled equipment, such as configuring a button to control the lights in the corridor, and a button to control the lights in the restaurant, it is necessary to modify the configuration.

Therefore, the present invention also includes modifying the configuration: reading and modifying the configuration information stored on the listening node through the Bluetooth MESH network, transmitting the modified configuration information to the listening node and overwriting the configuration information before modification.

The modified configuration of the present invention is the function of configuring the passive wireless switch, so the configuration information can be transmitted through the Bluetooth Mesh network, making the configuration process very convenient. The configuration can be modified through the node. The node can choose a mobile terminal with a display screen and Bluetooth function, including but not limited to mobile phones, PADs, computers, and various mobile devices with Bluetooth functions. Application software (App) for configuration , the App can read (using the Vendor model) the configuration information stored on the listening node through the Bluetooth Mesh network. The mobile terminal can open a visual interface for users to configure according to the capabilities of the passive wireless switch. The modified configuration content includes but is not limited to 1. Response target range: single device, multi-device, logical group, broadcast, 2. Response action: switch , Dimming, Scene, Timing, etc.; 3. Combined action response: double-click operation function selection, long-press operation function selection, etc. For example, if the user needs to configure the No. 2 button on the passive wireless switch to control the switch of the corridor light, the information recorded in the corresponding configuration information 1, the adv corresponding to the button, 2, the logical group where the corridor light is located 3, the switch operation, 4. No additional actions.

After the user setting is completed, the mobile terminal transmits the modified configuration information to the monitoring node through the Bluetooth Mesh network Vendor model, and the monitoring node receives the modified configuration information and saves it locally. The modified configuration information will overwrite the configuration before modification information. Afterwards, when the listening node receives the adv packet broadcast by the corresponding passive wireless switch, it will translate the modified configuration information into a Bluetooth Mesh data packet and send it out through the Bluetooth Mesh network.

The present invention also proposes a passive wireless switch control system based on Bluetooth MESH network, including

Passive wireless switch with bluetooth communication function, used to broadcast adv packet according to trigger action, multiple buttons can be set on it, and the function of each button can be defined according to needs.

The Bluetooth MESH network has several nodes, at least one node is selected as the monitoring node, and several nodes are set as the controlled devices; the monitoring node receives the adv packet broadcast by the passive wireless switch for analysis, and translates it according to the stored configuration information to obtain the Bluetooth MESH data packet, and forward the Bluetooth MESH data packet in the Bluetooth MESH network; the non-target device in the controlled device receives the Bluetooth MESH data packet and forwards it, and the target device in the controlled device receives the Bluetooth MESH data packet and responds.

The system of the present invention adopts the above-mentioned passive wireless switch control method based on the bluetooth MESH network to realize the control of the controlled device.

The above is only a specific embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any non-substantial changes made to the present invention by using this concept should be an act of violating the protection scope of the present invention.
