Description

[0001] The present invention relates to the technical field of Bluetooth Mesh communication control, and in particular to a connection method and device for a proxy device, a storage medium, and an electronic device. Background Art

[0002] In scenarios such as smart homes, commercial building automation, and industrial IoT, BLE Mesh networks, or Bluetooth low energy mesh networks, are particularly suitable. They have the characteristics of high reliability, scalability, and low power consumption, making them an ideal choice for IoT device interconnection. Devices in a BLE Mesh network communicate via Bluetooth broadcasts. When a terminal device (such as a mobile phone) wants to communicate with a device in a BLE Mesh network in order to control it, it needs to directly connect (GATT) to a proxy device (that is, a device that supports proxy), which forwards the message to the corresponding device that needs to be controlled.

[0003] In the prior art, a terminal device directly connects to the first proxy device scanned in the BLE Mesh network. After the connection is successful, the terminal device will continue to use the proxy device until the connection is disconnected and then connect to a new proxy device.

[0004] The first proxy device scanned in the prior art has the problem of connection timeout due to unstable signal, and when the terminal device moves, the signal of the connected proxy device may become worse, and the communication stability is not guaranteed at this time.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0053] like Figure 1 FIG. 1 is a flow chart of a connection method for a proxy device disclosed in an embodiment of the present invention, and the method is applied to a terminal device. It should be noted that the terminal device is a terminal device supporting Bluetooth, such as a mobile phone.

[0054] The connection method of the proxy device mainly includes the following steps:

[0055] Step S101: Use Bluetooth to scan in real time the broadcast information sent by each device to be connected in the BLE Mesh network.

[0056] It should be noted that BLE Mesh network, namely Bluetooth Low Energy Mesh Network, is a wireless communication technology that is based on Bluetooth technology but has been extended to support multi-hop communication and more complex network topologies. Compared with traditional Bluetooth technology, the advantage of BLE Mesh is that it can support more devices to connect at the same time, and through multi-hop communication, the signal can be relayed through multiple intermediate devices, thereby expanding the coverage of the signal and reducing the problem of signal attenuation.

[0057] In step S101, in the BLE Mesh network, devices that support proxy are devices to be connected. When the signal strength of these devices meets the requirements, they can be connected to the terminal device as proxy devices.

[0058] It should be noted that the proxy device is used to receive messages from the terminal device and forward them to other devices in the BLE Mesh network, or receive messages from other devices in the BLE Mesh network and forward them to the terminal device.

[0059] In one embodiment, the broadcast information obtained by Bluetooth scanning needs to be subjected to multiple layers of verification to verify whether the broadcast information comes from the device to be connected in the BLE Mesh network.

[0060] Specifically, it first verifies whether the specified content in the proxy broadcast is consistent with the data encrypted by the networkkey of the BLE Mesh network. Then it compares the mac address in the broadcast information with the mac address of the device (node) in the BLE Mesh network information.

[0061] Step S102: extracting the corresponding signal strength for each broadcast information sent by the device to be connected.

[0062] In step S102, the device to be connected will send out a proxy broadcast (service uuid is 1828), so that after the terminal device obtains the Bluetooth scan, the terminal device can know the signal strength of the device to be connected according to the scanned broadcast.

[0063] Step S103: If the signal strength of the device to be connected is greater than the preset backup signal strength threshold, determine whether the terminal device is connected to the backup device; if not, execute step S104.

[0064] It can be understood that if the signal strength of the device to be connected is less than or equal to the preset standby signal strength threshold, it can be determined that the connection requirement is not met and subsequent connection will not be performed.

[0065] The preset standby signal strength threshold may be 75 dBm.

[0066] In step S103, both the backup device and the proxy device are connected to the terminal device, and the two cooperate with each other. When the proxy device signal deteriorates, the current proxy device is disconnected and the backup device is switched to the proxy device, so as to realize the senseless switching of the proxy device and avoid the situation of signal disconnection. The backup device can also take on the sending of some messages for the proxy device.

[0067] It is understandable that when a terminal device has a backup device connected to it, there must also be a proxy device connected to it. Therefore, it is possible to determine whether the terminal device is connected to a backup device by the number of devices currently connected to the terminal device. The details are as follows:

[0068] Get the number of devices connected to the terminal device in the BLE Mesh network. If the number of devices is less than 2, it is determined that the terminal device is not connected to the backup device.

[0069] That is, when the number of devices is less than 2, the terminal device can only be connected to a proxy device, or there is no connected device.

[0070] Step S104: Determine that the device to be connected is a target device, and connect to the target device.

[0071] In step S104, if the target device is not successfully connected within a preset time (eg, two seconds), the target device is determined to be a problematic device, and the connection with the target device is stopped.

[0072] Step S105: Determine whether the terminal device is equipped with a corresponding proxy device; if not, execute step S106; if so, execute step S107.

[0073] In the specific implementation process of step S105, the number of devices in the BLE Mesh network to which the terminal device is currently connected is obtained. If the number of devices is equal to 1, it is determined that the terminal device is connected and a corresponding proxy device is set.

[0074] Step S106: Setting the target device as a proxy device.

[0075] Step S107: Determine whether the signal strength of the proxy device is greater than a preset proxy signal strength threshold; if so, execute step S108; if not, execute step S109.

[0076] In step S107, the devices in the BLE Mesh network that have established a connection with the terminal device can directly read the Bluetooth signal strength.

[0077] The proxy signal strength threshold needs to be greater than or equal to the standby signal strength threshold. For example, if the standby signal strength threshold is 75 dBm, the proxy signal strength threshold may be 80 dBm.

[0078] Step S108: setting the target device as a standby device and monitoring the signal strength of the proxy device; when the signal strength of the proxy device is less than or equal to the proxy signal strength threshold, disconnecting the proxy device and switching the standby device to the proxy device.

[0079] In step S108, the signal strength of the proxy device may be detected once at a preset time interval (eg, 5 seconds).

[0080] It should be noted that disconnecting the original proxy device with poor signal and switching the standby device to the new proxy device are performed simultaneously to achieve seamless switching and prevent signal interruption.

[0081] In one embodiment, after the target device is set as a standby device, the signal strength of the standby device is monitored; when the signal strength of the standby device is less than or equal to a standby signal strength threshold, the connection with the standby device is disconnected.

[0082] It is understandable that as long as there is a corresponding backup device for the terminal device, the signal strength of the backup device will be monitored. When the signal strength of the backup device signal is less than or equal to the backup signal strength threshold, it is determined that it does not meet the conditions to serve as a proxy device and the connection is disconnected in time.

[0083] Specifically, the signal strength of the backup device may be detected once at a preset time interval (eg, 5 seconds).

[0084] In another embodiment, since the connection will be disconnected when the signal strength of the backup device is less than or equal to the backup signal strength threshold, there is a situation where the terminal device has been disconnected from the backup device before detecting that the signal strength of the proxy device is less than or equal to the proxy signal strength threshold. At this time, the operation of switching from the backup device to the proxy device cannot be completed. At this time, the connection with the proxy device is still maintained until the proxy device update is completed through steps S101 to S106.

[0085] Step S109: disconnecting the proxy device and setting the target device as the proxy device.

[0086] In step S109, since the current proxy device signal strength is relatively poor, the target device is directly set as a proxy device without setting the target device as a backup device first.

[0087] In one embodiment, the terminal device may be provided with multiple backup devices. When the proxy device signal strength is less than or equal to the proxy signal strength threshold, a backup device is randomly selected and switched to the proxy device and the original proxy device is disconnected.

[0088] It should be noted that due to the limitations of the Bluetooth performance of terminal devices and the number of connections, it is not recommended to connect too many devices as backup devices. If Bluetooth performance is the highest priority, only one backup device is required.

[0089] Based on the connection method of a proxy device disclosed in the above embodiment of the present invention, in this scheme, when the signal strength of the device to be connected meets the requirements, it is set as a proxy device or a backup device. When the signal strength of the proxy device deteriorates, the backup device is switched to the proxy device, thereby achieving the purpose of improving the success rate of connecting with the proxy device and improving the stability of communication during the movement of the terminal device.

[0090] Based on the above embodiment of the present invention, a connection method of a proxy device is disclosed, such as Figure 2 As shown, it is a flowchart of another connection method of a proxy device disclosed in an embodiment of the present invention, which is applied to a terminal device that pre-sets the maximum number of devices that can be connected to the BLE Mesh network at the same time as 1, and includes the following steps:

[0091] Step S201: Use Bluetooth to scan in real time the broadcast information sent by each device to be connected in the BLE Mesh network.

[0092] Step S202: extracting the corresponding signal strength for each broadcast information sent by the device to be connected.

[0093] It should be noted that the specific implementation process of steps S201 to S202 can be found in the above-mentioned embodiment of the present invention, which will not be described again here.

[0094] Step S203: updating the device queue in real time based on the signal strength corresponding to each device to be connected.

[0095] It should be noted that if the terminal device has just turned on Bluetooth, it is necessary to wait for the device queue to be updated (for example, wait for 3 seconds) so that there are enough devices to be connected and their corresponding signal strengths in the device queue before executing the subsequent connection process.

[0096] Preferably, it is determined whether the signal strength of the scanned device to be connected is greater than the proxy signal strength threshold (e.g., 80dBm). If so, the device queue is updated based on the device to be connected and its corresponding signal strength, thereby ensuring that the device to be connected in the device queue at least meets normal communication requirements.

[0097] Step S204: query the device queue for the device to be connected with the greatest signal strength and determine it as the preferred device.

[0098] Step S205: Initiate a connection process with the preferred device and determine whether the connection with the preferred device is successful within a preset time. If yes, execute step S206; if no, execute step S207.

[0099] Step S206: Setting the preferred device as a proxy device.

[0100] Preferably, after the preferred device is set as the proxy device, the signal strength of the proxy device is monitored, and if the signal strength of the proxy device is less than or equal to a preset proxy signal strength threshold (eg, 80 dBm), the process returns to step S204.

[0101] When the connection with the preferred device is successful, the connection with the current proxy device is disconnected and the preferred device is set as the new proxy device, and the signal strength of the proxy device is returned to be monitored continuously.

[0102] Step S207: Determine that the preferred device is the problem device, query the device queue for a device to be connected with the greatest signal strength other than the problem device, and determine it as the new preferred device, and return to execute step S205.

[0103] Based on the connection method of a proxy device disclosed in the above-mentioned embodiment of the present invention, in this scheme, a device with the largest signal strength is selected from a real-time updated device queue as a proxy device, and when the signal strength of the proxy device deteriorates, it returns to reselect the device with the largest signal strength as the proxy device, thereby achieving the purpose of improving the success rate of connecting with the proxy device and improving the stability of communication during the movement of the terminal device.

[0106] The first judgment unit 302 is used to judge whether the terminal device is connected to the backup device if the signal strength of the device to be connected is greater than a preset backup signal strength threshold; if not, determine that the device to be connected is the target device and connect to the target device.
