[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0042] In the prior art, to reduce power consumption, a longer broadcast period is set for Bluetooth devices to reduce the broadcast packet sending frequency, thereby extending the battery life. However, this will result in a longer device discovery and Bluetooth connection time. Users may need to wait for several seconds to complete the Bluetooth connection, reducing the user experience. To overcome the above technical problems, this application proposes a Bluetooth connection method.

[0043] An embodiment of this application discloses a Bluetooth connection method. Refer to Figure 1 As shown, the method may include the following steps:

[0044] Step S11: Receive a wireless signal sent by a mobile device through the NFC module, and send a trigger signal to the Bluetooth module of the Bluetooth device according to the wireless signal.

[0045] In this embodiment, the Bluetooth module in the Bluetooth device is in the off mode by default; or in the low-power mode to reduce power consumption. At this time, the Bluetooth broadcast period is long (such as 1.28 seconds), and it takes a long time to establish a Bluetooth connection. To improve the Bluetooth connection speed between the user's mobile device and the Bluetooth device in this embodiment, the Bluetooth device is first notified to increase the broadcast frequency through NFC (Near Field Communication). Specifically, after the NFC module of the Bluetooth device receives the wireless signal sent by the NFC module of the mobile device, the NFC module of the Bluetooth device sends a trigger signal to the Bluetooth module of the Bluetooth device according to the wireless signal to notify the Bluetooth module that the broadcast period needs to be adjusted. The NFC module of the Bluetooth device is the passive party and does not require power supply from the Bluetooth device.

[0046] In some embodiments, sending the trigger signal to the Bluetooth module of the Bluetooth device according to the wireless signal may include: the NFC module sending Bluetooth trigger information to the control unit of the Bluetooth device according to the wireless signal; the control unit sending a trigger signal to the Bluetooth module according to the Bluetooth trigger information. That is, the trigger of the Bluetooth module is specifically implemented through the control unit. The NFC module first sends Bluetooth trigger information to the control unit of the Bluetooth device to notify the control unit to execute the control of the Bluetooth module, and the control unit sends a trigger signal to the Bluetooth module according to the Bluetooth trigger information.

[0047] The control unit sending the trigger signal to the Bluetooth module according to the Bluetooth trigger information may include: the control unit determining the current mode of the Bluetooth module; if the current mode is the off mode, starting the Bluetooth module, and after the Bluetooth module is started, sending the trigger signal to the Bluetooth module according to the Bluetooth trigger information; that is, the Bluetooth module needs to be started first, and then the Bluetooth module is controlled to adjust the broadcast period. If the current mode is the low-power mode, directly sending the trigger signal to the Bluetooth module according to the Bluetooth trigger information.

[0048] In some embodiments, the control unit is connected to the Bluetooth module through input / output pins; the control unit sending the trigger signal to the Bluetooth module according to the Bluetooth trigger information includes: the control unit sending the trigger signal to the Bluetooth module by adjusting the level of the pin corresponding to the Bluetooth module. The pin of the control unit is connected to the pin of the Bluetooth module, and the trigger is achieved by changing the level of the pin, such as raising the level from low to high.

[0049] Step S12: The Bluetooth module shortens the broadcast period of the Bluetooth signal according to the trigger signal, so that the mobile device can establish a Bluetooth connection with the Bluetooth device through the Bluetooth signal.

[0050] After the Bluetooth module receives the trigger signal, it shortens its own advertising cycle, that is, increases the advertising frequency, so that the user can discover and connect more quickly. For example, after the Bluetooth module receives the trigger signal, it switches to the fast advertising mode, and the advertising cycle is adjusted to a shorter value (such as 20 milliseconds) to facilitate the mobile phone to quickly discover the device.

[0051] In some embodiments, the Bluetooth module shortens the advertising cycle of the Bluetooth signal according to the trigger signal, so that the mobile device establishes a Bluetooth connection with the Bluetooth device through the Bluetooth signal, including: the Bluetooth module adjusts the advertising cycle of the Bluetooth signal to be below the target duration according to the trigger signal, so that the mobile device quickly establishes a Bluetooth connection with the Bluetooth device through the Bluetooth signal; the advertising cycle duration of the Bluetooth module in the low power consumption mode is greater than the target duration. That is, the target duration (such as 30 milliseconds) can be set in advance. After the Bluetooth module receives the trigger signal, it adjusts the Bluetooth advertising cycle to at least the target duration and below. By defining the target duration, it is ensured that when the mobile device needs to connect, the Bluetooth device broadcasts at a high frequency so as to be discovered by the mobile device in time.

[0052] Specifically, the above-mentioned Bluetooth module shortening the advertising cycle of the Bluetooth signal according to the trigger signal may include: obtaining the current remaining power of the Bluetooth device; querying the pre-created power partition table to determine the target power range corresponding to the current remaining power; querying the mapping relationship between the power partition and the advertising cycle duration pre-created to determine the advertising cycle duration corresponding to the target power range as the target duration; the more the remaining power, the shorter the advertising cycle duration. Of course, the function relationship between the remaining power and the advertising cycle duration can also be directly constructed in advance, and in the function relationship, the more the remaining power, the shorter the advertising cycle duration. That is, when the remaining power is sufficient, a higher frequency can be used for Bluetooth advertising so as to be discovered by the mobile device more quickly. When the remaining power is not sufficient, a slightly higher frequency can be used for Bluetooth advertising to improve the connection speed as much as possible on the basis of avoiding excessive power consumption.

[0053] Step S13: Obtain the operation instruction sent by the mobile device through the Bluetooth connection, and restore the Bluetooth module to the default mode after completing the execution of the operation instruction; the default mode is the off mode or the low power consumption mode.

[0054] After Bluetooth is established, receive the operation instructions sent by the mobile device via Bluetooth connection, so that the device can perform corresponding operations according to the operations; after the operations are completed, restore the Bluetooth mode of the device to the default mode to avoid power consumption in the high-frequency broadcast mode for a long time. Specifically, restoring the Bluetooth module to the default mode includes: obtaining the current remaining power of the Bluetooth device; if the current remaining power is greater than or equal to the preset power threshold, adjust the Bluetooth module to the low-power mode; if the current remaining power is less than the preset power threshold, adjust the Bluetooth module to the off mode. This can avoid potential security risks caused by the Bluetooth being in the broadcast mode for a long time and being maliciously scanned or attempted to be connected.

[0055] The above mobile device can be a mobile device using the IOS system. It can be understood that in many scenarios, the IOS system only supports reading NFC data exchange format tags, rather than direct data transmission between devices. For example, IOS devices can read the information in NFC tags, but do not support file transfer or data sharing between devices via NFC like Android devices. This results in the IOS system being unable to interact with other devices using NFC. For example, an IOS device cannot use NFC to unlock a smart door lock because it cannot transmit the door lock unlocking data. Instead, in this embodiment, NFC is first used to trigger Bluetooth only, and then the device is unlocked via Bluetooth after the Bluetooth connection is established.

[0056] Among them, the above Bluetooth connection method further includes: establishing a Bluetooth connection with a Bluetooth gateway through the Bluetooth module; after the operation instructions are executed, sending the corresponding operation event to the Bluetooth gateway, and using the Bluetooth gateway to report the operation event to the server, so that the client can obtain the operation event through the server. The Bluetooth gateway can be installed on other devices that are not Bluetooth devices but can be connected to Bluetooth devices via Bluetooth. By reporting the occurred operation events to the server through the Bluetooth gateway, the server can notify the user in a timely manner through the client application, and it is also convenient for the user to view the occurred operation events in real time through the client application at any time. In addition, the connection between the Bluetooth module and the Bluetooth gateway can be established in the low-power mode or after the Bluetooth module is started. The Bluetooth module continuously sends broadcast packets to enable the Bluetooth gateway to discover and establish a connection.

[0057] In a specific embodiment, the above Bluetooth device is a smart door lock; the operation instruction is an unlocking instruction. The Bluetooth connection system includes: a smart door lock main body and a client application (App). The smart door lock main body includes a lock body mechanical part, a control unit, a Bluetooth module, an NFC module, and a power supply. The Bluetooth module is a chip that supports Bluetooth Low Energy (BLE) communication and is used for broadcasting, connection, and unlocking command processing; the NFC module is used to receive the approaching signal from the mobile phone and notify the Bluetooth module; the power supply module is powered by a battery to ensure low-power operation; the mobile phone application (App) is used to discover Bluetooth devices, initiate connections, and send unlocking instructions. When the user's mobile phone approaches the door lock, the NFC module built into the mobile phone communicates with the NFC module on the door lock. After the NFC module of the Bluetooth device senses the mobile phone signal passively, it sends a trigger signal to the Bluetooth module. The NFC module does not require external power supply for the door lock, reducing the overall power consumption. Correspondingly, obtaining the operation instruction sent by the mobile device through the Bluetooth connection includes: obtaining the unlocking instruction sent by the mobile device through the Bluetooth connection and authenticating the unlocking instruction; if the mobile device passes the authentication, the door lock is controlled to unlock according to the unlocking instruction. That is, after the mobile phone scans the Bluetooth broadcast signal of the door lock through the App, it initiates a connection request. The Bluetooth module of the door lock completes the pairing connection with the mobile phone through the handshake protocol. The mobile phone sends an unlocking instruction through Bluetooth, and the door lock verifies the identity of the mobile phone. After the verification is passed, the door lock executes the unlocking action and sends a feedback signal to the Bluetooth module. After the unlocking operation is completed, the Bluetooth module returns to the low-power broadcast mode to reduce the standby power consumption.

[0058] For example Figure 2 The figure shows a flowchart of a specific battery-powered smart door lock Bluetooth connection method. The low-power Bluetooth module establishes a connection with the Bluetooth gateway in the low-power mode. When the mobile device approaches, the NFC of the Bluetooth device responds and sends trigger information to the control unit (such as an MCU (Microcontroller Unit)), and the control unit notifies the Bluetooth module. The Bluetooth module shortens the broadcast period, establishes a Bluetooth connection with the mobile device, receives the unlocking request sent by the mobile device through the Bluetooth connection, forwards the unlocking request to the control unit. After the control unit passes the verification, it executes the unlocking operation and sends the unlocking success message to the Bluetooth module. The Bluetooth module feeds back the unlocking success message to the client application of the mobile device so that the user can disconnect the Bluetooth. Finally, the Bluetooth module reports the unlocking event to the server through the Bluetooth gateway.

[0059] The intelligent control method triggered by combining Bluetooth Low Energy communication and Near Field Communication (NFC) is used to optimize the connection speed and power consumption performance of Bluetooth devices. It is applicable to the application scenarios of smart door locks and other Bluetooth devices that require low-power operation and fast connection response, such as battery-powered sensors.

[0060] As can be seen from the above, in this embodiment, the NFC module receives the wireless signal sent by the mobile device, and sends a trigger signal to the Bluetooth module of the Bluetooth device according to the wireless signal; the Bluetooth module shortens the broadcast period of the Bluetooth signal according to the trigger signal, so that the mobile device can establish a Bluetooth connection with the Bluetooth device through the Bluetooth signal; the operation instruction sent by the mobile device is obtained through the Bluetooth connection, and the Bluetooth module is restored to the default mode after the operation instruction is executed; the default mode is the off mode or the low-power mode. It can be seen that when it is necessary to establish a Bluetooth connection with the Bluetooth device, the Bluetooth device is notified to shorten the broadcast period of the Bluetooth signal, that is, to increase the broadcast packet sending frequency, which is convenient for the mobile device to quickly discover the device, so that the connection with the Bluetooth device can be quickly established. After the instruction is executed, the Bluetooth module is restored to the default mode. In the default mode, the Bluetooth does not consume power or consumes low power, so as to reduce the standby power consumption; moreover, the NFC trigger mechanism is used to dynamically adjust the Bluetooth broadcast frequency, so that the Bluetooth device enters the fast broadcast mode when needed, and is restored to the default mode after the instruction is executed. The NFC module in the Bluetooth device does not need to be powered as a passive party, further reducing the overall power consumption.
