Description

Technical Field

[0001] The present invention relates to the technical field of Bluetooth, and in particular to a method for intelligent Bluetooth pairing. Background Art

[0002] Bluetooth is an open global standard for wireless data and voice communications. It is a special short-range wireless technology connection based on low-cost short-range wireless connection to establish a communication environment for fixed and mobile devices.

[0003] The existing Bluetooth pairing methods on the market usually have the following disadvantages: Complex operation: It is usually necessary to manually search for available devices in the Bluetooth settings of the device, and then select the Bluetooth headset to be paired from the list. The steps are relatively cumbersome and may be confusing for users who are not familiar with the operation of electronic devices; Slow pairing: The search and connection process may take a long time, especially in an environment with many Bluetooth devices around. The devices need to be scanned and identified one by one, causing users to wait for a long time; Error-prone: When manually selecting a device, other Bluetooth devices may be mistakenly selected, or pairing errors may occur due to similar device names. The pairing operation needs to be performed again, affecting the user experience; Lack of status prompts: During the pairing process, the user may not be clear about the current status of the headset, such as whether it is searching or ready to pair, etc., resulting in the user being unable to accurately judge the next step.

[0004] Therefore, a method for intelligent Bluetooth pairing is urgently needed. Summary of the invention

[0005] The object of the present invention is to provide a smart Bluetooth pairing method to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a method for intelligent Bluetooth pairing, comprising the following steps: when the Bluetooth headset has no historical record of pairing with any device, open the charging box cover, the headset will automatically turn on and enter the Bluetooth pairing state for a preset time, and at the same time send out a BLE pop-up broadcast so that other devices can discover and connect to it. When the pairing is completed within the preset time, the headset enters standby mode. If the pairing is not successful within the time limit, it enters factory mode.

[0007] Preferably, when the Bluetooth headset has a historical pairing record, after taking it out of the charging box, press and hold any headset button for a preset time within a preset time, the headset will enter the Bluetooth pairing state for the preset time, and send out a BLE pop-up broadcast at the same time. If the pairing is completed within the preset time, the headset enters standby mode. If it is not completed, it enters an undiscoverable connectable state, but can be actively connected by a recorded device.

[0008] Preferably, when the Bluetooth headset has a pairing record and is in the charging box with the lid closed, when the charging box cover is opened, the headset will automatically reconnect and enter the Bluetooth pairing state for a preset time. After the preset time, a BLE pop-up broadcast will be issued. If a device is connected, the headset will enter standby mode. If not, it will enter an undiscoverable connectable state.

[0009] Preferably, when the Bluetooth headset is connected to a device, if it detects that Bluetooth is turned off or receives an active disconnection command, the headset will automatically enter a 90-second Bluetooth pairing state and send an Advertising Data Packet containing the device name and battery level through the BLE protocol, triggering a pop-up prompt on the target device; if pairing is not completed within 90 seconds, the headset switches to non-discoverable but connectable mode, and only allows historical paired devices to actively connect.

[0010] Preferably, after the headset enters the undiscoverable connectable state, it is shut down if there is no connection after a timeout of 30 minutes.

[0011] Preferably, the headset will display corresponding status prompt information while sending out the BLE pop-up broadcast.

[0012] Preferably, the content of the BLE pop-up broadcast is customized according to user preferences or device type, such as displaying the device name, battery information or special function prompts, to enhance the user experience.

[0013] Preferably, the system also includes a mobile application or software used in conjunction with the Bluetooth headset or charging box to provide a user interface, configuration options, status monitoring, and linkage functions with other smart devices.

[0014] Preferably, it includes a Bluetooth headset and a charging box. The Bluetooth headset has a built-in Bluetooth module and a processor for executing related operations in the pairing process. The charging box has a built-in power management module and a communication module for providing power support for the headset and communicating with the headset. The charging box communicates with the headset through the UART protocol to synchronize the power and status in real time.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: First, in the present invention, when a user purchases and uses a certain Bluetooth headset for the first time, the headset will automatically turn on and enter the Bluetooth pairing state for 90 seconds when the user's mobile phone or other Bluetooth device can search for the headset and display the BLE pop-up broadcast. The user clicks the pairing button in the pop-up window to complete the pairing operation. If the pairing is not completed within 90 seconds, the headset will enter the shipping state. mode, waiting for the next pairing operation; the user has paired the Bluetooth headset with mobile phone A and now wants to pair it with mobile phone B. The user takes the headset out of the charging box and presses any headset button for 5 seconds within 1 minute. At this time, the headset will enter the Bluetooth pairing state for 90 seconds and send out a BLE pop-up broadcast. The user searches for the headset in the Bluetooth settings of mobile phone B and clicks the pairing button to complete the pairing operation. If the pairing is not completed within 90 seconds, the headset will enter an undiscoverable and connectable state for 30 minutes, but can still be actively connected by mobile phone A during this period. If the pairing is still not successful after the timeout, the headset will shut down and end the process; the user has paired the Bluetooth headset with mobile phone A and used it. One day, the user puts mobile phone A and the headset in the bag. After a while, when the headset needs to be used again, it opens the cover of the charging box, and the headset will automatically connect back to mobile phone A (if the Bluetooth of mobile phone A is turned on and in a connectable state). At the same time, the headset will enter a 90-second mode. The Bluetooth pairing status of the headset is displayed, and a BLE pop-up broadcast is issued (if mobile phone A is not connected or is not within the connectible range). At this time, if the user has other devices (such as tablet B) that want to pair with the headset, he only needs to search for the headset in the Bluetooth settings of tablet B and click the pairing button to complete the pairing operation. If mobile phone A does not connect to the headset after 5 seconds, the headset will enter an undiscoverable connectable state for 20 minutes. After the timeout, if other devices complete the pairing, the headset will enter standby mode; otherwise, the headset will shut down and end the process. By introducing a variety of ways to automatically enter the pairing mode, such as automatically entering the pairing when opening the cover and reconnecting, and automatically entering the pairing when actively disconnected, the steps of manual search and selection by users in the device settings are reduced, making the pairing process more convenient and efficient. Through specific trigger mechanisms (such as opening the cover, pressing buttons, etc.), the headset can quickly enter the pairing state and complete the pairing in a shorter time (such as 90 seconds), which greatly shortens the waiting time compared to traditional methods.

[0016] Second, the present invention uses the specific field Manufacturer Specific Data transmission customized information, after being parsed by the device side, is displayed as a pop-up window. When the headset tries to establish a connection with a paired device (such as a smartphone, tablet computer, etc.), it will send a BLE pop-up window broadcast. At the same time as the BLE pop-up window broadcast is sent, the headset will also display the corresponding status prompt information through its own display screen (if available) or the device interface connected to it. This information helps users understand the current pairing status, headset power, special function prompts, etc. This broadcast method can quickly attract the user's attention and start the pairing process. There are clear status prompts at each process node, entering a connectable or unconnectable state for different lengths of time, etc., so that users can clearly understand the real-time status of the headset, which is convenient for users to make correct operational decisions and reduce incorrect operations caused by unclear status. The system can automatically adjust the display content of the BLE pop-up window based on the user's historical behavior, setting preferences and other information. For example, users may prefer a concise and clear device name display, or pay special attention to power information. Different types of paired devices may have different requirements for the content of the BLE pop-up window. For example, smartphone users may prefer to see the power information and special function prompts of the headset, while smart watch users may pay more attention to the compatibility information of the device.

[0017] Third, in the present invention, the user opens the mobile application or software, and the application automatically scans the nearby Bluetooth devices. When a Bluetooth headset or charging box is found, the application displays the device name and status. The user selects the target device, and the application tries to establish a Bluetooth connection. If the device is in the "non-discoverable but In the "connectable" mode, the application can be connected through a preset pairing code or a known device address. Users can set linkage rules with other smart devices in the application, such as automatically turning off the mobile phone speaker when the headset is connected, and automatically pausing music playback when the headset is disconnected. The application exchanges data and transmits commands with other smart devices through communication protocols such as Bluetooth or Wi-Fi. The application communicates with the Bluetooth headset or charging box through the Bluetooth protocol to realize functions such as device connection, data transmission and status monitoring. It supports BLE technology to reduce power consumption and improve connection stability. The linkage with the Bluetooth headset box is realized through the APP application. The user interface provides an intuitive and easy-to-use interface, allowing users to easily manage the pairing, connection, settings and other functions of the Bluetooth headset. The configuration options allow users to customize the settings of the Bluetooth headset according to their preferences and needs, such as volume, sound effects, touch operation, etc., and display the power, connection status and other information of the Bluetooth headset and charging box in real time to help users understand the device status at any time. The rich configuration options, status monitoring and linkage functions enable users to better understand and control their devices and improve usage satisfaction. At the same time, the hardware cannot be continuously updated, but the mobile application or software can be continuously updated to adapt to more types of smart devices and operating systems, and improve the compatibility and availability of the device. BRIEF DESCRIPTION OF THE DRAWINGS

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.

[0019] Embodiment 1 like Figure 1 As shown, the present invention provides a technical solution: a smart Bluetooth pairing method, comprising the following steps: when the Bluetooth headset has no historical record of pairing with any device, open the charging box cover, the headset will automatically turn on and enter the Bluetooth pairing state for a preset time, and at the same time send out a BLE pop-up broadcast so that other devices can discover and connect to it. The pairing is completed within the preset time, and the headset enters standby mode. If the pairing is not successful within the time limit, it enters factory mode.

[0020] Among them, BLE pop-up broadcast technology refers to using the broadcast function of the BLE device to send specific broadcast data packets to nearby receiving devices, thereby triggering pop-up prompts or interactive interfaces on the receiving devices. In the BLE protocol, broadcast data packets containing specific information are sent out periodically. These data include device name, service UUID, manufacturer-specific data, etc.

[0021] When the Bluetooth headset has a historical pairing record, after taking it out of the charging box, press and hold any headset button for a preset time within the preset time. The headset will enter the Bluetooth pairing state for the preset time and send out a BLE pop-up broadcast. If the pairing is completed within the preset time, the headset will enter standby mode. If it is not completed, it will enter an undiscoverable connectable state, but can be actively connected by a recorded device.

[0022] Among them, the non-discoverable but connectable state is the non-discoverable but connectable mode. According to the Bluetooth core specification, when the device is in this mode, it will not respond to normal or limited query requests from other devices, thereby remaining in an undiscoverable state. However, for known or paired devices, this device can still accept connection requests initiated by them to ensure that data transmission or communication can be carried out when needed.

[0023] When the Bluetooth headset has a pairing record and is in the charging box with the cover closed, open the charging box cover and the headset will automatically reconnect and enter the Bluetooth pairing state for the preset time. After the preset time, it will start to send BLE pop-up broadcasts. If a device is connected, the headset will enter standby mode. If not, it will enter the undiscoverable connectable state.

[0024] When the Bluetooth headset is connected to a device, if it detects that Bluetooth is turned off or receives an active disconnection command, the headset will automatically enter the Bluetooth pairing state for 90 seconds and send an AdvertisingData Packet containing the device name and battery level through the BLE protocol, triggering a pop-up prompt on the target device; if pairing is not completed within 90 seconds, the headset switches to non-discoverable but connectable mode, and only allows historical paired devices to actively connect.

[0025] After the headset enters the undiscoverable connectable state, it will shut down if there is no connection after 30 minutes.

[0026] Through the above technical solution, when a user purchases and uses a Bluetooth headset for the first time, the headset will automatically turn on and enter the Bluetooth pairing state for 90 seconds when the user opens the charging box cover. At this time, the user's mobile phone or other Bluetooth device can search for the headset and display the BLE pop-up broadcast. The user clicks the pairing button in the pop-up window to complete the pairing operation. If the pairing is not completed within 90 seconds, the headset will enter the shipping state. mode, waiting for the next pairing operation; the user has paired the Bluetooth headset with mobile phone A and now wants to pair it with mobile phone B. The user takes the headset out of the charging box and presses any headset button for 5 seconds within 1 minute. At this time, the headset will enter the Bluetooth pairing state for 90 seconds and send out a BLE pop-up broadcast. The user searches for the headset in the Bluetooth settings of mobile phone B and clicks the pairing button to complete the pairing operation. If the pairing is not completed within 90 seconds, the headset will enter an undiscoverable and connectable state for 30 minutes, but can still be actively connected by mobile phone A during this period. If the pairing is still not successful after the timeout, the headset will shut down and end the process; the user has paired the Bluetooth headset with mobile phone A and used it. One day, the user puts mobile phone A and the headset in the bag. After a while, when the headset needs to be used again, it opens the cover of the charging box, and the headset will automatically connect back to mobile phone A (if the Bluetooth of mobile phone A is turned on and in a connectable state). At the same time, the headset will enter a 90-second mode. The Bluetooth pairing status of the headset is displayed, and a BLE pop-up broadcast is issued (if mobile phone A is not connected or is not within the connectible range). At this time, if the user has other devices (such as tablet B) that want to pair with the headset, he only needs to search for the headset in the Bluetooth settings of tablet B and click the pairing button to complete the pairing operation. If mobile phone A does not connect to the headset after 5 seconds, the headset will enter an undiscoverable connectable state for 20 minutes. After the timeout, if other devices complete the pairing, the headset will enter standby mode; otherwise, the headset will shut down and end the process. By introducing a variety of ways to automatically enter the pairing mode, such as automatically entering the pairing when opening the cover and reconnecting, and automatically entering the pairing when actively disconnected, the steps of manual search and selection by users in the device settings are reduced, making the pairing process more convenient and efficient. Through specific trigger mechanisms (such as opening the cover, pressing buttons, etc.), the headset can quickly enter the pairing state and complete the pairing in a shorter time (such as 90 seconds), which greatly shortens the waiting time compared to traditional methods.
