Description

Bluetooth connection method and Bluetooth device

Technical Field

The present application relates to the field of short-distance communication technologies, and in particular, to a bluetooth connection method and a bluetooth device.

Background

With the development of random bluetooth headsets, true Wireless Stereo (TWS) headsets have been able to establish a wireless connection with two electronic devices (e.g., mobile phones, tablet computers, etc.) at the same time, which can handle audio services (e.g., playing music, making/receiving calls, etc.) of the two electronic devices.

TWS headsets during processing of audio traffic of one electronic device, the TWS headset may be disconnected from another electronic device for some reason. At this time, the TWS headset cannot handle the audio traffic of the other electronic device. If the user still needs to use the TWS headset to handle the audio traffic of the other electronic device, first, the user needs to perform the relevant operations on the other electronic device. The other electronic device then triggers the TWS headset to reconnect to the other electronic device to reestablish a connection with the other electronic device based on the operation.

However, the inventors found that at least the following problems exist in the prior art: after the related operation is required to be performed on the electronic device disconnected from the TWS headset, the TWS headset can be connected back to the electronic device, which results in a cumbersome connection back process and thus lower connection back efficiency.

Disclosure of Invention

In view of this, the present application provides a bluetooth connection method and a bluetooth device, which improve the backhaul efficiency.

In a first aspect, the present application provides a bluetooth connection method, which is applied to a bluetooth device that establishes bluetooth connections with a plurality of electronic devices; the Bluetooth device is an input/output device of the plurality of electronic devices, and is used for playing or acquiring audio corresponding to any one of the plurality of electronic devices; the method comprises the following steps:

the Bluetooth equipment interacts with first electronic equipment in the plurality of electronic equipment and processes audio service of the first electronic equipment; wherein the first electronic device is any one of the plurality of electronic devices;

in the process of processing the audio service of the first electronic device, if the Bluetooth connection between the Bluetooth device and the second electronic device is disconnected, the Bluetooth device automatically connects back to the second electronic device; the second electronic device is at least one of the plurality of electronic devices except the first electronic device.

In this embodiment of the application, in the process that the bluetooth device processes the audio service of the first electronic device, if the bluetooth connection between the bluetooth device and the second electronic device is disconnected, the bluetooth device may automatically reconnect the second electronic device once to reestablish the bluetooth connection with the second electronic device, thereby implementing active reconnection of the bluetooth device. The Bluetooth device can automatically connect back to the second electronic device without the need of the user to perform relevant operations. And in addition, the Bluetooth device only connects the second electronic device back once in the process of processing the audio service of the first electronic device, and does not connect the second electronic device back many times. Therefore, the time for the bluetooth device to connect back to the second electronic device to occupy the resource (such as an air interface resource) is short, so that the audio service of the first electronic device is not affected, and the audio service can be prevented from being blocked.

In a possible design, the bluetooth disconnection indicates a bluetooth disconnection overtime, and the bluetooth disconnection indicates that the bluetooth device or the second electronic device does not receive a data packet from the other party within a period of time.

In a possible design, after the automatic reconnection of the second electronic device fails, the bluetooth device stops automatically reconnecting the second electronic device, and determines whether the audio service of the first electronic device is finished;

and under the condition that the audio service of the first electronic equipment is determined to be finished, the Bluetooth equipment continues to automatically connect back to the second electronic equipment.

And the Bluetooth device continues to automatically reconnect the second electronic device, and the Bluetooth device can automatically reconnect the second electronic device every second preset time.

In this embodiment of the application, in the process of processing the audio service of the first electronic device by the bluetooth device, if the bluetooth connection between the bluetooth device and the second electronic device is disconnected, the bluetooth device may automatically connect back to the second electronic device once. If the second electronic device fails to be connected back, the Bluetooth device can stop automatically connecting back the second electronic device so as to prevent the audio service of the first electronic device from being blocked. Then, the bluetooth device may continue to automatically reconnect the second electronic device after the audio service of the first electronic device is ended, so as to improve the success rate of reconnecting the second electronic device on the basis of preventing the audio service of the first electronic device from being affected.

In a possible design, when the bluetooth device continues to automatically connect back to the second electronic device, the number of times of connection back corresponding to the second electronic device is counted. If the continuous reconnection fails, the Bluetooth device stops automatically reconnecting the second electronic device after the first reconnection times are equal to the preset reconnection times.

The first connection times are the total times of the Bluetooth device automatically connecting the second electronic device; or the first connection times are the times that the Bluetooth device automatically connects the second electronic device after the audio service of the first electronic device is finished.

In this embodiment of the present application, when the audio service of the first electronic device is ended, that is, the bluetooth device does not process the audio service of the first electronic device any more, it indicates that the bluetooth device is connected back to the second electronic device, and the audio service of the first electronic device is not affected. Therefore, the bluetooth device may continue to automatically connect back to the second electronic device, and count the number of times of connection back (i.e. the first number of times of connection back) corresponding to the second electronic device. And under the condition that the automatic reconnection of the second electronic equipment fails, the Bluetooth equipment judges whether the first reconnection time is equal to a preset reconnection time. If the first number of times of reconnection is equal to the preset number of times of reconnection, which indicates that although the bluetooth device has automatically reconnected the second electronic device a plurality of times, the second electronic device has no successful reconnection, an abnormality may occur in the second electronic device (for example, the second electronic device is too far away from the bluetooth device). Therefore, to avoid the reconnection causing a waste of resources, the bluetooth device stops automatically reconnecting the second electronic device. If the first reconnection time is less than the preset reconnection time, the Bluetooth device can continue to automatically reconnect the second electronic device and continue to update the reconnection time so as to judge whether to perform next automatic reconnection after the current reconnection fails by using the reconnection time.

In one possible design, the bluetooth device may be an earpiece of a TWS headset.

In one possible design, after the bluetooth device fails to connect back to the second electronic device, the bluetooth device stops automatically connecting back to the second electronic device;

after receiving the target trigger operation, the Bluetooth device responds to the target trigger operation and is connected back to the second electronic device; wherein the target triggering operation triggers the target earplug to be back-connected.

Wherein the target triggering operation comprises any one of: the earplugs are taken out of the box, the earplugs of the TWS earphone are uncovered, the earplugs are switched from an unworn state to a worn state, the two earplugs of the TWS earphone establish a Bluetooth connection, a user triggers the operation that the TWS earphone is connected back to the second electronic equipment on the second electronic equipment, and the user triggers the operation that the TWS earphone is connected with new electronic equipment.

In this embodiment of the application, in the process of processing the audio service of the first electronic device by the bluetooth device, if the bluetooth connection between the bluetooth device and the second electronic device is disconnected, the bluetooth device may automatically connect back to the second electronic device once. If the second electronic device fails to be connected back, the Bluetooth device can stop automatically connecting back the second electronic device so as to prevent the audio service of the first electronic device from being blocked. The bluetooth device may then continue to connect back to the second electronic device to establish a bluetooth connection with the second electronic device in dependence on the received other action, i.e. the target trigger operation, for the bluetooth device.

In a second aspect, the present application provides a bluetooth communication system comprising a plurality of electronic devices and a bluetooth device according to any one of the first aspect.

In a third aspect, the present application provides a bluetooth device comprising a memory, a wireless communication module, a receiver and microphone, and one or more processors; the memory, the wireless communication module, the headphones, and the microphone are coupled with the processor; wherein the wireless communication module is configured to wirelessly communicate with an electronic device, the memory having stored therein computer program code comprising computer instructions which, when executed by the processor, cause the bluetooth device to perform the bluetooth connection method according to any of the first aspect.

Detailed Description

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present embodiment, "a plurality" means two or more unless otherwise specified.

In some usage scenarios, as shown in fig. 1, a peripheral device 101 (e.g., a bluetooth device such as a TWS headset) may establish a bluetooth connection with multiple electronic devices 100 (e.g., mobile phones) simultaneously to perform audio data transmission with any of the multiple electronic devices 100, so that the electronic devices 100 may process audio traffic of the multiple electronic devices 100. The electronic device 100 may be referred to as a Master (Master, abbreviated as M), and the peripheral device may be referred to as a Slave (Slave, abbreviated as S).

During audio data transmission by the peripheral device 101 with one of the plurality of electronic devices 100, the bluetooth connection between the peripheral device 101 and the other electronic device may be disconnected. At this time, the user may input an operation of connecting the peripheral device 101 on the target interface of the other electronic device, and the other electronic device attempts to re-establish the bluetooth connection with the peripheral device 101 in response to the operation. On the one hand, this kind of loop connection is inefficient. On the other hand, if the user fails to find in time that the bluetooth connection between the peripheral device 101 and the other electronic device is disconnected, the user cannot trigger in time, so that the other electronic device cannot try to establish the bluetooth connection with the peripheral device in time, the peripheral device 101 is affected to process the audio service of the other electronic device, and user experience is poor.

On the other hand, if the user performs the relevant operation on the other electronic device, the peripheral device 101 is not yet connected back to the other electronic device. The user may continue to perform related operations on the other electronic device at this time, causing the peripheral device 101 to connect back to the other electronic device multiple times. However, since the air interface resource of the peripheral device 101 is limited, when the peripheral device 101 connects back to the other electronic device, a certain proportion of the air interface resource needs to be occupied, which results in that the air interface resource occupied by the peripheral device 101 when transmitting the audio data corresponding to the electronic device is reduced. When the peripheral device 101 repeatedly connects back to the other electronic devices, the air interface resource corresponding to the electronic device 100 is continuously affected, and thus the audio service processed by the peripheral device 101 is blocked.

It should be noted that although the peripheral device 101 can establish bluetooth connection with multiple electronic devices 100 at the same time, it cannot process audio services of multiple electronic devices 100 at the same time, and can only process audio services of one electronic device. Therefore, in the process that the peripheral device 101 processes the audio service of one electronic device, when another electronic device needs to perform the audio service by using the peripheral device 101, the peripheral device 101 needs to perform switching of the audio service, so that the peripheral device 101 can process the audio service of the other electronic device.

Therefore, in view of the above problems, the present application provides a bluetooth connection method, in which a peripheral device can be bluetooth connected to a plurality of electronic devices at the same time. In the process that the peripheral device processes the audio service of one electronic device in the plurality of electronic devices, if the Bluetooth connection between the peripheral device and the other electronic devices is disconnected due to connection overtime, the peripheral device can actively connect back to the other electronic devices once, so that the active connection back of the peripheral device is realized. The peripheral equipment can automatically connect back to other electronic equipment without related operation of a user, and the back connection efficiency is improved. And, because the peripheral equipment will not connect back to the other electronic equipment many times in the course of processing the audio service of this electronic equipment. Therefore, the time for the peripheral device to connect back to the other electronic device to occupy the air interface resource is short, so that the audio service of the electronic device (i.e., the audio service processed by the peripheral device) is not affected, and the audio service is prevented from being blocked.

The electronic device may be, for example, a mobile phone (e.g., the mobile phone 200 shown in fig. 5), a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a Personal Digital Assistant (PDA), an Augmented Reality (AR) \ Virtual Reality (VR) device, a media player, a television, or the like, and the embodiment of the present application is not particularly limited to the specific form of the device.

The peripheral equipment can be TWS earphones, bluetooth sound boxes, intelligent glasses and other equipment capable of carrying out Bluetooth communication. When the number of bodies included in the peripheral device is plural, one or all of the bodies of the peripheral device may establish a bluetooth connection with the electronic device 100. A description will be given below of a manner in which the peripheral device 101 establishes a bluetooth connection with one electronic device 100 when the peripheral device 101 includes a plurality of bodies, with reference to fig. 2 to 4, taking an example in which the peripheral device 101 includes two bodies, such as the device (S1) 101-1 and the device (S2).

In one example, one body of the peripheral device 101 establishes a bluetooth connection with the electronic device 100. As shown in fig. 2 or fig. 3, one principal of the peripheral device 101 (e.g., device 101-1) may take a primary role and another principal (e.g., device 101-2) may take a secondary role. For example, when the peripheral device 101 is a TWS headset, one earpiece (e.g., the left earpiece) of the TWS headset may serve a primary role as the primary earpiece; the other earplug (e.g., the right earplug) may serve a secondary role as a secondary earplug. Of course, the roles played by the two bodies of the peripheral device 101 may be exchanged. For example, the left earplug may serve as a secondary earplug, serving a secondary role; the right earplug may serve as the primary earplug, serving a primary role.

Wherein the electronic device 100 may establish a first bluetooth connection with a principal (e.g., device 101-1) that plays a primary role. A principal in a primary role, such as device 101-1, may establish a second bluetooth connection with a principal in a secondary role, such as device 101-2.

In some embodiments, as shown in FIG. 2, device 101-1 and device 101-2 may communicate audio data with electronic device 100 in a listening manner. In particular, the device 101-1 in the primary role may send the connection parameters of the first bluetooth connection to the device 101-2 in the secondary role via the second bluetooth connection. In this way, when the electronic device 100 transmits the audio data packet to the device 101-1 in the primary role through the first bluetooth connection, the device 101-2 in the secondary role can listen to the audio data packet transmitted by the electronic device 100 according to the connection parameters of the first bluetooth connection. In this way, both subjects of the peripheral device 101 can acquire the audio data packet from the electronic device 100.

In this embodiment, the peripheral device 101 establishes bluetooth connections with the electronic devices 100 respectively, which may be that the device 101-1 playing a main role establishes first bluetooth connections with the electronic devices respectively. Accordingly, when the bluetooth connection between the peripheral device 101 and the electronic device 100 is disconnected, it may be the first bluetooth connection between the device 101-1 taking the main role and the electronic device 100 is disconnected. That is, the device 101-1 having a main role may be a bluetooth device (such as a true wireless stereo headset shown in fig. 8 and 9) as described in the embodiments of the present application, and perform the method of the embodiments of the present application.

In other embodiments, as shown in FIG. 3, device 101-1 and device 101-2 may communicate audio data with electronic device 100 in a repeating manner. Specifically, when the electronic device 100 sends an audio packet to the device 101-1 in the primary role over the first bluetooth connection, the device 101-1 in the primary role may forward the audio packet to the device 101-2 in the secondary role. In this way, both bodies of the peripheral device 101 can also acquire the audio data packet from the electronic device 100.

In another example, as shown in fig. 4, two bodies of the peripheral device 101 respectively establish bluetooth connections with the electronic device 100. Specifically, the electronic device 100 supports the wireless connection with the devices 101-1 and 101-2 of the peripheral device 101 through bluetooth, respectively, to implement short-range data exchange. For example, the mobile phone supports the wireless connection with the left and right earplugs of the TWS headset through bluetooth respectively, so as to realize short-distance data exchange. Illustratively, device 101-1 and device 101-2 may communicate audio data with electronic device 100 based on the wireless connection described above. For example, the device 101-1 and the device 101-2 implement a call as audio input/output devices of the electronic device 100. As another example, device 101-1 and device 101-2 implement music playback, etc., as output devices for electronic device 100.

In this embodiment, the peripheral device 101 respectively establishing bluetooth connections with the plurality of electronic devices 100 may be the device 101-1 and/or the device 101-2 of the peripheral device 101 respectively establishing bluetooth connections with the plurality of electronic devices. Accordingly, when the Bluetooth connection between the peripheral device 101 and the electronic device 100 is disconnected, the Bluetooth connection between the device 101-1 and the electronic device 100 may be disconnected, and/or the Bluetooth connection between the device 101-2 and the electronic device 100 may be disconnected. For example, in a case where the device 101-1 of the peripheral device 101 establishes bluetooth connections with the plurality of electronic devices 100, respectively, the bluetooth disconnection between the peripheral device 101 and the electronic device 100 may refer to the bluetooth disconnection between the device 101-1 and the electronic device 100. For another example, in a case where the device 101-2 of the peripheral device 101 establishes bluetooth connections with the plurality of electronic devices 100, the bluetooth disconnection between the peripheral device 101 and the electronic device 100 may be bluetooth disconnection between the device 101-2 and the electronic device 100. For another example, in a case where the device 101-1 and the device 101-2 of the peripheral device 101 respectively establish bluetooth connections with the plurality of electronic devices 100, the bluetooth connection disconnection between the peripheral device 101 and the electronic device 100 may refer to bluetooth connection disconnection between the device 101-1 and/or the device 101-2 and the electronic device 100. That is, the device 101-1 and/or the device 101-2 of the peripheral device 101 may perform the method of the embodiments of the present application as a bluetooth device (e.g., a true wireless stereo headset as shown in fig. 8 and 9) as described in the embodiments of the present application.

In this embodiment, the establishing, by bluetooth, the wireless connection between the peripheral device 101 and the electronic device 100 may specifically include: the electronic apparatus 100 establishes wireless connections with the two main bodies of the peripheral apparatus 101 through bluetooth, respectively. Short-range data exchange between the electronic device 100 and the two bodies of the peripheral device 101 can be realized based on respective wireless connections.

In the embodiment of the present application, after the electronic device 100 establishes a wireless connection with a peripheral device by using a wireless communication technology, such as bluetooth, the electronic device 100 may store a bluetooth address of the peripheral device in the internal memory. In some embodiments, when the peripheral device is a device comprising two bodies, such as a TWS headset, and the left and right earpieces of the TWS headset have respective bluetooth addresses, the electronic device 100 may store the bluetooth address association of the left and right earpieces of the TWS headset in the internal memory 1.

It should be understood that fig. 2 to 4 describe a process of connecting the peripheral device 101 to one electronic device 100 of a plurality of electronic devices, and the way of establishing the bluetooth connection with the peripheral device 101 by other electronic devices than the electronic device 100 of the plurality of electronic devices is similar to the process, and of course, the other electronic devices may also establish the bluetooth connection with the peripheral device by other ways, which is not limited in this application.

It should be noted that the data transmitted between the electronic device 100 and the peripheral device 101 includes, but is not limited to, the audio data. For example, the data transmitted by the electronic device 100 and the peripheral device 101 may also be picture or video data. For example, the peripheral device 101 is smart glasses, and the electronic device 100 may transmit picture or video data to lenses of the smart glasses. In the embodiment of the present application, the method of the embodiment of the present application is described by taking the example that the electronic device 100 and the peripheral device 101 transmit audio data.

As an example, the peripheral device 101 may be at least one earphone of the TWS headset 201 shown in fig. 5, and the electronic device 100 may be the mobile phone 200 shown in fig. 5. Wherein the TWS headset 201 comprises two bodies, such as an earpiece 201-1 and an earpiece 201-2. Wherein, the earplug 201-1 can be a left earplug of the TWS earpiece 201, and the earplug 201-2 is a right earplug; alternatively, the earplug 201-1 may be a right earplug of the TWS earpiece 201 and the earplug 201-2 a left earplug. One of the earplugs (e.g., the earplug 201-1) of the TWS headset 201 may serve as a primary earplug of the TWS headset, and the other earplug (e.g., the earplug 201-2) may serve as a secondary earplug of the TWS headset. The primary and secondary roles of the left and right earplugs of the TWS headset may be interchanged. In the embodiment of the present application, the structures of the earplugs 201-1 and 201-2 of the TWS headset 201 are shown in FIG. 7, which will be described in detail in the following embodiments.

As shown in fig. 6, the TWS headset 201 may include: a left earplug 201-1, a right earplug 201-2 and an earplug box 201-3. The earplug case may be used to receive left and right earplugs of a TWS headset. Fig. 6 is a schematic diagram showing an example of a product form of the TWS headset by way of example only, and the product form of the peripheral device provided by the embodiment of the present application includes, but is not limited to, the TWS headset 201 shown in fig. 6.

Please refer to fig. 7, which is a schematic structural diagram of an earplug (a left earplug or a right earplug) of a TWS earphone according to an embodiment of the present application. As shown in fig. 7, the earplugs (e.g., the right earpiece 201-2) of the TWS headset 201 may include: a processor 210, a memory 220, a sensor 230, a wireless communication module 240, a receiver 250, a microphone 260, and a power supply 270.

The memory 220 may be used for storing application code, such as for establishing a wireless connection with another earpiece of the TWS headset 201, such as the right earpiece 201-2, and for enabling a pairing connection of the earpieces with the electronic device 100, such as the handset 200. The processor 210 may control execution of the above-mentioned application program code to implement the functionality of the earpieces of the TWS headset in the embodiments of the present application.

The memory 220 may also have stored therein a bluetooth address for uniquely identifying the earpiece and a bluetooth address of another earpiece of the TWS headset. In addition, the memory 220 may also store connection data with an electronic device that the earplug has been successfully paired with before. For example, the connection data may be a bluetooth address of the electronic device that was successfully paired with the earpiece. Based on the connection data, the ear bud can be automatically paired with the electronic device without having to configure a connection therewith, such as for legitimacy verification or the like. The bluetooth address may be a Media Access Control (MAC) address.

The sensor 230 may be a distance sensor or a proximity light sensor. The ear bud may determine whether it is being worn by the user via the sensor 230. For example, the earbud may utilize a proximity light sensor to detect whether an object is near the earbud to determine whether the earbud is being worn by a user. Upon determining that the earbud is worn, the earbud can open the receiver 250. In some embodiments, the earplug may further include a bone conduction sensor incorporated into a bone conduction earpiece. By utilizing the bone conduction sensor, the earplug can acquire the vibration signal of the sound part vibration bone block, analyze the voice signal and realize the voice function. In other embodiments, the ear bud may further include a touch sensor for detecting a touch operation of a user. In other embodiments, the ear bud may further include a fingerprint sensor for detecting a user's fingerprint, identifying the user's identity, and the like. In other embodiments, the earplug may further comprise an ambient light sensor that adaptively adjusts parameters, such as volume, based on the perceived brightness of the ambient light.

A wireless communication module 240 for supporting short-range data exchange between the earpieces of the TWS headset and various electronic devices, such as the electronic device 100 described above. In some embodiments, the wireless communication module 240 may be a bluetooth transceiver. The earplugs of the TWS headset can establish a wireless connection with the electronic device 100 through the bluetooth transceiver to realize short-distance data exchange between the two.

At least one receiver 250, which may also be referred to as a "headset," may be used to convert the electrical audio signals into sound signals and play them. For example, when the earpiece of the TWS headset serves as the audio output device of the electronic device 100, the receiver 250 may convert the received audio electrical signal into a sound signal and play the sound signal.

At least one microphone 260, which may also be referred to as a "microphone," is used to convert sound signals into electrical audio signals. For example, when the ear-piece of the TWS headset 201 is used as the audio input device of the electronic device 100, the microphone 260 may collect the voice signal of the user and convert the voice signal into an audio electrical signal during the process of speaking (such as talking or making voice message) by the user. The audio electrical signal is audio data in the embodiment of the present application.

A power supply 270 may be used to supply power to the various components contained in the earplugs of the TWS headset 201. In some embodiments, the power source 270 may be a battery, such as a rechargeable battery.

Typically, the TWS headset 201 will be equipped with an earbud cartridge (e.g., 201-3 shown in FIG. 6). The earplug case may be used to receive left and right earplugs of a TWS headset. As shown in FIG. 6, the earplug case 201-3 may be used to receive the left earplug 201-1 and the right earplug 201-2 of a TWS headset. In addition, the earpiece box may also charge the left and right earpieces of the TWS earpiece 201. Accordingly, in some embodiments, the above-described earplug may further comprise: an input/output interface 280. The input/output interface 280 may be used to provide any connection between earplugs of a TWS headset and an earpiece box, such as the earpiece box 201-3 described above.

In some embodiments, the input/output interface 280 may be an electrical connector. When the earplugs of the TWS headset 201 are disposed in the earbud box, the earplugs of the TWS headset 201 may be electrically connected to the earbud box (e.g., to an input/output interface of the earbud box) via the electrical connector. After this electrical connection is established, the earpiece box may charge the power supply 270 for the earpieces of the TWS headset. After this electrical connection is established, the earplugs of the TWS headset 201 may also be in data communication with the earpiece box. For example, the earplugs of the TWS headset 201 may receive pairing instructions from the earpiece box through the electrical connection. The pairing command is used to instruct the earpieces of the TWS headset 201 to turn on the wireless communication module 240 so that the earpieces of the TWS headset 201 can be paired with the electronic device 100 using a corresponding wireless communication protocol, such as bluetooth.

Of course, the earplugs of the TWS headset 201 described above may also not include the input/output interface 280. In this case, the ear buds may implement a charging or data communication function based on the wireless connection established with the ear bud case through the above-described wireless communication module 240.

Additionally, in some embodiments, an earbud cartridge (such as earbud cartridge 301 described above) may also include a processor, memory, and the like. The memory may be used to store application program code and be controlled for execution by the processor of the earplug cassette to implement the functions of the earplug cassette. For example. When the user opens the lid of the earplug case, the processor of the earplug case may send a pairing command or the like to the earplugs of the TWS headset in response to the user opening the lid by executing application code stored in the memory.

It is to be understood that the illustrated structure of the embodiments of the present application does not constitute a specific limitation to the earplugs of the TWS headset 201. It may have more or fewer components than shown in fig. 7, may combine two or more components, or may have a different configuration of components. For example, the earplug may further include an indicator light (which may indicate the status of the earplug, such as its power level), a dust screen (which may be used with the earpiece), and the like. The various components shown in fig. 7 may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing or application specific integrated circuits.

It should be noted that the left and right earplugs of the TWS headset 201 may be identical in structure. For example, the left and right earplugs of the TWS earpiece 201 may both include the components shown in FIG. 7. Alternatively, the structure of the left and right earplugs of the TWS headset 201 may also be different. For example, one earpiece (e.g., the right earpiece) of the TWS headset 201 may include the components shown in fig. 7, while the other earpiece (e.g., the left earpiece) may include other components in fig. 7 besides the microphone 260.

In the embodiment of the application, the peripheral device establishes Bluetooth connection with a plurality of electronic devices simultaneously. In the process that the peripheral device processes the audio service (such as playing music) of one electronic device in the plurality of electronic devices, if the bluetooth connection between the peripheral device and the other electronic device is disconnected, the peripheral device can be connected back to the other electronic device to reestablish the bluetooth connection with the other electronic device, so that the automatic connection back of the peripheral device is realized, the connection back efficiency is improved, and the audio service corresponding to the electronic device is not influenced. The following takes two electronic devices as an example, where the two electronic devices are both mobile phones (i.e., the mobile phone 1 and the mobile phone 2), and the peripheral device is a TWS headset, and the technical solution of the present application will be described with reference to a specific example.

The bluetooth connection method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings. As shown in fig. 8, the method comprises the steps of:

s301, bluetooth connection is established between the true wireless stereo headset and the mobile phone 1 and the mobile phone 2 respectively.

In an embodiment of the present application, the TWS headset may send a broadcast message to the outside. If the handset 1 has bluetooth enabled, the handset 1 may receive the broadcast message and the handset 1 may prompt the user that the associated bluetooth device (e.g., TWS headset) has been scanned. When a user selects the TWS headset as a connection device on the mobile phone 1, the mobile phone 1 can be connected with the TWS headset in a pairing manner, so that the TWS headset can establish a bluetooth connection with the mobile phone 1. Similarly, if the handset 2 has bluetooth enabled, the handset 2 may receive the broadcast message and the handset 1 may prompt the user that the associated bluetooth device (e.g., the TWS headset) has been scanned. When the user selects the TWS headset as the connection device on the mobile phone 2, the mobile phone 2 can be connected in a pairing manner with the TWS headset, so that the TWS headset can establish a bluetooth connection with the mobile phone 2.

In some embodiments, the TWS headset may first establish a bluetooth connection with the handset 1. Then, after the TWS headset has established a connection with the handset 1, the TWS headset may send a broadcast message to the outside again to establish a bluetooth connection with the handset 2 in response to a user-related operation (e.g., the user clicks the TWS headset a certain number of times, e.g., the user keeps holding down a switch key on an earpiece of the TWS headset to put the TWS headset into a bluetooth pairing state, etc.). Of course, the TWS headset may also establish a bluetooth connection with the handset 2 first, and then with the handset 1.

In some embodiments, the TWS headset establishes bluetooth connections with the mobile phone 1 and the mobile phone 2 respectively, and one earplug of the TWS headset may establish bluetooth connections with the mobile phone 1 and the mobile phone 2. For example, as shown in fig. 2 or fig. 3, the TWS headset may establish bluetooth connections with the mobile phone 1 and the mobile phone 2 respectively, that is, the main earpiece of the TWS headset establishes bluetooth connections with the mobile phone 1 and the mobile phone 2 respectively. For another example, as shown in fig. 4, both earplugs of the TWS headset can establish bluetooth connection with the host device, so that any one of the earplugs of the TWS headset can establish bluetooth connection with the mobile phone 1 and the mobile phone 2 respectively.

In other embodiments, the TWS headset establishes bluetooth connections with the mobile phone 1 and the mobile phone 2, and may be that two earplugs of the TWS headset respectively establish bluetooth connections with the mobile phone 1, and two earplugs of the TWS headset respectively establish bluetooth connections with the mobile phone 2. For example, as shown in fig. 4, both earplugs of the TWS headset can establish bluetooth connection with the host device, and thus, both earplugs of the TWS headset can respectively establish bluetooth connection with the mobile phone 1 and the mobile phone 2.

For example, the broadcast message may include at least one of a device name, a device type, a device model, a battery level, a wearing state, a connection state, or a service state of the TWS headset. Wherein the connection status information may indicate that the bluetooth connection has been established. The traffic status information may indicate whether the TWS headset is currently idle, i.e., indicating whether the TWS headset is processing audio traffic.

Accordingly, after the TWS headset is connected to the mobile phone 1 and/or the mobile phone 2, the related information of the TWS headset may also be displayed, for example, at least one of the device name, the device model, the power amount, the wearing status, the service status information, the connection status information, and the like of the TWS headset.

S302, the true wireless stereo headset interacts with the mobile phone 1, and the true wireless stereo headset processes the audio service of the mobile phone 1.

The TWS headset may receive the audio data packet sent by the mobile phone 1 based on the bluetooth connection between the TWS headset and the mobile phone 1, and process the related audio service (such as playing music) of the mobile phone 1.

In one case, if there is a bluetooth connection between the primary earpiece of the TWS headset and the handset 1, the handset 1 may send audio data packets to the primary earpiece. The secondary earplug of the TWS headset may retrieve the audio data packet based on a listening mode or a forwarding mode.

In another case, if there is a bluetooth connection between the two earpieces of the TWS headset and the mobile phone 1, respectively, the mobile phone 1 may send an audio data packet to each of the two earpieces based on the bluetooth connection between the two earpieces and the mobile phone 1, respectively. In another case, if there is a bluetooth connection between one earpiece of the TWS headset and the handset 1, the other earpiece being in an unused state (e.g. the other earpiece is still in the earpiece box), the handset 1 may send an audio data packet to the one earpiece based on the bluetooth connection between it and the one earpiece.

In some embodiments, the TWS headset may still maintain a bluetooth connection with the handset 2 during the processing of the audio traffic of the handset 1. The TWS headset may continuously send packets to the handset 2 (e.g., periodically send packets to the handset 2) while the TWS headset is in bluetooth connection with the handset 2. After receiving the data packet, the mobile phone 2 may return a response message to the TWS headset, where the response message indicates that the mobile phone 2 has received the data packet. The data packet may include information such as the amount of power of the TWS headset.

And S303, in the process of processing the audio service of the mobile phone 1, if the Bluetooth connection between the true wireless stereo headset and the mobile phone 2 is disconnected, the true wireless stereo headset automatically connects back to the mobile phone 2.

Wherein the loopback represents a process of reconnecting the host device after the peripheral device is disconnected from the host device. Specifically, the connection back may indicate a process that the TWS headset may send a paging (page) packet to the paired handset 2 after the connection between the TWS headset and the handset 2 is disconnected, so as to recover the connection.

In this embodiment, in the process of processing the audio service of the mobile phone 1, if the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected due to a connection timeout, which indicates that the TWS headset cannot process the audio service of the mobile phone 2, the TWS headset automatically sends a page data packet to the mobile phone 2, and the mobile phone 2 is reconnected once. If the TWS headset still does not successfully establish a bluetooth connection with the handset 2 beyond a first preset time (e.g., 5 seconds), the TWS headset may determine that this reconnection failed and stop automatically reconnecting the handset 2. If the TWS earphone is successfully connected with the mobile phone 2 within the first preset time, the connection of the TWS earphone and the mobile phone 2 is successfully established, and the connection is successfully completed.

The connection timeout indicates that the mobile phone 2 does not receive a data packet from the TWS headset within a period of time or the TWS headset does not receive response information from the mobile phone 2 within a period of time due to a reason that a distance between the mobile phone 2 and the TWS headset is greater than a certain value and a signal strength (RSSI) between the mobile phone 2 and the TWS headset is smaller than a preset threshold. In short, the connection timeout indicates that the mobile phone 2 or the TWS headset does not receive the information sent by the other party for a period of time.

In the embodiment of the present application, the TWS headset serves as an input/output device of the mobile phone 1 and the mobile phone 2, and the TWS headset establishes a bluetooth connection with the mobile phone 1 and the mobile phone 2, respectively. In the process of processing the audio service of the mobile phone 1, if the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected due to connection timeout, the TWS headset is connected back to the mobile phone 2 once, so that automatic connection of the TWS headset is realized, the connection process is simple, user operation is not needed, the connection efficiency can be effectively improved, and untimely connection caused by that the user does not find the TWS headset is disconnected from the mobile phone 2 in time can be avoided, so that the TWS headset can process the audio service of the mobile phone 2 in time after the connection success. Moreover, because the mobile phone 2 is connected back only once, the time that the TWS headset occupies air interface resources when the mobile phone 2 is connected back is short, so that the influence on the audio service of the mobile phone 1 is small, and the phenomenon of blocking when the TWS headset plays audio data of the mobile phone 1 is avoided. For example, when a user plays a game using the handset 1, the TWS headset plays the game sound effects of the handset 1. And during the playing process of the game sound effect of the mobile phone 1 by the TWS earphone, the Bluetooth connection between the TWS earphone and the mobile phone 2 is disconnected. In order to avoid influencing the playing effect of the game sound effect, the TWS earphone is only connected with the mobile phone 2 in a loop, and the mobile phone 2 is not connected in a loop any more no matter whether the connection is successful or not, so that the phenomenon of pause in the game sound effect of the mobile phone 1 can be avoided, the game sound effect of the mobile phone 1 can be ensured to be synchronous with the game picture, and the user experience is improved. For another example, in the process that the user uses the TWS headset to play the music of the mobile phone 1, the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected, and in order to avoid affecting the playing of the music of the mobile phone 1, the TWS headset is connected back to the mobile phone 2 only once, thereby ensuring that the TWS headset normally plays the music of the mobile phone 1.

In some embodiments, the TWS headset stops automatic reconnection after a failure to automatically reconnect the handset 2 once. The TWS headset may continue to reconnect the cell phone 2 after receiving the target trigger operation, i.e., the TWS headset may continue to reconnect the cell phone 2 in response to the target trigger operation if the target trigger operation is received after the TWS headset stops automatically reconnecting the cell phone 2. Wherein the target trigger operation may trigger the TWS headset to make N round trips. The N is a positive integer.

Illustratively, the above target triggering operation may be an operation in which the user turns on an ear plug box of the TWS headset. If the user wants the TWS headset to connect back to the handset 2, he may first put the TWS headset back into the ear-bud box after the service of the handset 1 is over. The user then opens the earpiece box again and the TWS headset may connect back the handset 2N times in response to this operation. If the number N is 7, correspondingly, if the TWS headset is not successfully reconnected after 7 times of reconnecting the handset 2, the TWS headset stops reconnecting the handset 2.

The above target triggering operation may be an operation in which the user takes out the TWS headset from the ear plug case. If the user wants the TWS headset to connect back to the handset 2, he may first put the TWS headset back into the ear-bud box after the service of the handset 1 is over. The user then reopens the earplug case and removes the TWS headset from the earplug case. The TWS headset may be connected back to the handset 2N times in response to a user's operation to remove the TWS headset from the earbud box. For example, the number of N times is 1 time. Accordingly, if the TWS headset is not successfully reconnected after being reconnected to the handset 2 for 1 time, the TWS headset stops reconnecting the handset 2.

The above target trigger operation may be an operation in which the user wears the TWS headset. If the user wants the TWS headset to connect back to the handset 2, he can re-wear the TWS headset. The TWS headset may be connected back to the handset 2N times in response to a user wearing the TWS headset. For example, the N times may be 1 time. Accordingly, if the TWS headset is not successfully reconnected after being reconnected to the handset 2 for 1 time, the TWS headset stops reconnecting the handset 2.

The target triggering operation may be an operation that the TWS headset is successfully paired with a new electronic device, that is, an operation that the user triggers the TWS headset to connect to the new electronic device. If the TWS headset is successfully paired with a new electronic device (e.g., a cell phone), the TWS headset will connect to the previously paired electronic device, and therefore the TWS headset will connect back to the cell phone 2N times if it is successfully configured with the new electronic device. For example, the number of N times is 1 time.

The above-mentioned target triggering operation may be a two-ear reconnection operation of the TWS headset. The two earplugs of a TWS headset are in a disconnected state for some reasons, such as too far distance between the two earplugs, one earplug outside the earplug case and the other earplug inside the earplug case, etc. At least one of the two earplugs can be connected back to the mobile phone 2N times if the two earplugs are re-connected. For example, the number of N times is 1 time. Thus, the user may perform a first operation (e.g., pulling the distance between the two earplugs away) and then perform a second operation (e.g., re-pulling the distance between the two earplugs closer) so that the TWS headset may perform a reconnect operation.

The target triggering operation may be an operation of the user to trigger the TWS headset to connect the mobile phone 2 back on the second electronic device, that is, the user inputs an operation of connecting the mobile phone 2 on the target interface of the mobile phone 2. The target interface indicates a configuration interface for the bluetooth connection. If the user wants the TWS headset to connect back to the handset 2, he can enter the relevant action on the target interface on the handset 2. The handset 2 receives the operation and sends a corresponding request to the TWS headset in response to the operation. The TWS headset receives the request and connects back to the handset 2N times in response to the request. For example, the N times may be 1 time.

It should be understood that the above target triggering operation may be performed in a case where the audio service of the handset 1 is ended. And the above listed target triggering operation is only an example, and the target triggering operation may also be other types of operations, for example, when the user clicks the TWS headset for a set number of times. The TWS headset connects back to the handset 2 in response to the click operation; for another example, when the TWS headset has an on-off key, the user may touch the on-off key. The TWS headset reconnects the handset 2 in response to the click operation.

It should be noted that the disconnection of the bluetooth connection between the TWS headset and the mobile phone 2 may be the disconnection of the bluetooth connection between one earplug (such as the above-mentioned main earplug) of the TWS headset and the mobile phone 2, or the disconnection of the bluetooth connection between the two earplugs of the TWS headset and the mobile phone 2.

In other embodiments, after the automatic reconnection of the mobile phone 2 once fails, the TWS headset may further continue to automatically reconnect the mobile phone 2 after the audio service of the mobile phone 1 is ended, thereby improving the success rate of the reconnection on the basis of avoiding affecting the audio service of the mobile phone 1. As shown in fig. 9, this process specifically includes:

s401, bluetooth connection is established between the true wireless stereo headset and the mobile phone 1 and the mobile phone 2 respectively.

S402, the true wireless stereo headset interacts with the mobile phone 1, and the true wireless stereo headset processes the audio service of the mobile phone 1.

S403, in the process of processing the audio service of the mobile phone 1, if the bluetooth connection between the wireless stereo headset and the mobile phone 2 is disconnected, the wireless stereo headset automatically connects back to the mobile phone 2.

The processes of S401 to S403 in this embodiment are similar to the processes of S301 to S303, and are not described herein again.

And S404, stopping automatically connecting the mobile phone 2 under the condition that the real wireless stereo headset fails to automatically connect the mobile phone 2.

S405, under the condition that the audio service of the mobile phone 1 is finished, the true wireless stereo headset automatically connects back the mobile phone 2 every second preset time, and the times of connection back are counted.

And S406, stopping automatic reconnection when the mobile phone 2 is reconnected successfully or the number of times of reconnection is equal to the preset number of times of reconnection.

In the embodiment of the present application, during the process of processing the audio service of the mobile phone 1, if the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected due to a timeout connection, the TWS headset may automatically connect back to the mobile phone 2 once. Then, after the automatic reconnection fails, it indicates that the TWS headset still does not successfully establish the bluetooth connection with the mobile phone 2, and the TWS headset can determine whether the audio service of the mobile phone 1 is finished, so as to continue to automatically reconnect the mobile phone 2 after the audio service of the mobile phone 1 is finished, thereby avoiding the influence on the audio service of the mobile phone 1 caused by the TWS headset repeatedly reconnecting the mobile phone 2.

In some embodiments, the TWS headset may determine whether the audio service of the handset 1 is over by determining whether the audio data packet sent by the handset 1 is received. For example, if the TWS headset does not receive the audio data packet sent by the handset 1 for a period of time, the TWS headset may consider the audio service of the handset 1 to be over.

The mobile phone 1 may stop sending the audio data packet to the TWS headset after the audio service 1 is ended, so that the TWS headset may not receive the audio data packet sent by the mobile phone 1 within a period of time. The TWS headset may not receive the audio data packet sent by the mobile phone 1, and may also be because the bluetooth between the TWS headset and the mobile phone 1 is disconnected, so that the mobile phone 1 cannot send the audio data packet to the mobile phone 1 again. Of course, the TWS headset may not receive the audio data packet sent by the handset 1 for some time due to other reasons, and the description of the reason is omitted here.

In some embodiments, in the process of processing the audio service of the mobile phone 1, if the automatic reconnection of the mobile phone 2 fails, the TWS headset stops automatically reconnecting the mobile phone 2, and records the reason information for stopping reconnecting the mobile phone 2.

The reason information includes at least one of an audio service due to the use of the TWS headset by the handset 1 (i.e., the TWS headset handles the audio service of the handset 1) and an abnormality of the handset 2.

For example, a handset 2 anomaly may indicate that the distance between the handset 2 and the TWS headset is too long, the signal strength between the handset 2 and the TWS headset is too low, or the handset 2 is malfunctioning, etc.

Of course, after the TWS headset fails to automatically reconnect to the handset 2, the TWS headset may also be deactivated to the handset 2 for other reasons, for example, the user triggers the TWS headset to deactivate the handset, etc.

In the embodiment of the present application, when the audio service of the mobile phone 1 is finished, that is, the TWS headset does not process the audio service of the mobile phone 1 any more, it indicates that the TWS headset reconnects to the mobile phone 2 without affecting the audio service of the mobile phone 1, so that the TWS headset can continue to automatically reconnect to the mobile phone 2, and count the number of times of reconnection corresponding to the mobile phone 2. In case of failure to automatically reconnect the handset 2 again, the TWS headset determines whether the number of reconnects is equal to a preset number of reconnects. If the number of times of the reconnection equals the preset number of times of reconnection, indicating that although the TWS headset has automatically reconnected the handset 2 a number of times, there is no success of the reconnection, an abnormality may occur in the handset 2 (for example, the handset 2 is too far away from the TWS headset). Thus, to reduce the waste of resources resulting from the reconnection, the TWS headset stops automatically reconnecting the handset 2.

If the number of times of the reconnection is less than the preset number of times of the reconnection, the TWS headset may continue to automatically reconnect the mobile phone 2, and continue to count the number of times of the reconnection, so as to determine whether to perform the next automatic reconnection after the current reconnection fails by using the number of times of the reconnection.

When the mobile phone 2 fails to be reconnected again, after a second preset time, the TWS headset may determine whether the number of reconnection times is equal to the preset number of reconnection times. And under the condition that the reconnection time is less than the preset reconnection time, the TWS earphone carries out the next automatic reconnection. Or, in case of failure of the mobile phone 2, the TWS headset determines whether the number of times of reconnection is equal to a preset number of times of reconnection. And when the reconnection time is less than the preset reconnection time, after a second preset time, the TWS earphone performs next automatic reconnection to realize periodic reconnection.

In some embodiments, the number of reconnections described above indicates the total number of times that the TWS headset automatically reconnects the handset 2 since the TWS headset was disconnected from the handset 2 due to a connection timeout. The initial value of the number of times of the reconnection is 0, and the number of times of the reconnection is increased by 1 every time the TWS headset automatically reconnects the headset 2.

Illustratively, the preset number of reconnection times is 60 times. In the process that the TWS headset processes the audio service of the mobile phone 1, if the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected, the TWS headset automatically reconnects the mobile phone 2 once, and the number of times of reconnection at this time becomes 1. If the TWS headset does not reconnect to the successful handset 2, then the automatic reconnection of the handset 2 is stopped. Then, after the audio service of the mobile phone 1 is finished, the TWS headset continues to automatically reconnect to the mobile phone 2 once, and the number of times of reconnection becomes 2. If the TWS earphone is not connected back to the successful mobile phone 2, the number of times of connection back is 2, and the number of times of connection back is smaller than the preset number of times of connection back, the TWS earphone still continues to automatically connect back to the mobile phone 2.

Then, if the continuous reconnection fails, the TWS headset continues to automatically reconnect the mobile phone 2 when the number of times of reconnection is less than the preset number of times of reconnection. In the case where the number of times of reconnection is 59 times, if the TWS headset has not been reconnected to the successful handset 2 yet, the TWS headset continues to automatically reconnect the handset 2 once. At this time, the number of times of reconnection became 60. If the mobile phone 2 still fails to be connected back, since the number of times of the back connection is already 60, which is equal to the preset number of times of the back connection, the TWS headset stops connecting back the mobile phone 2.

In other embodiments, the number of times of the above-mentioned reconnection indicates the total number of times that the TWS headset automatically reconnects the handset 2 after the audio service of the handset 1 is finished. The initial value of the number of times of this loop is 0 and the tws headset increments the number of times of this loop by 1 every time the headset is automatically looped back 2. For example, after the audio service of the handset 1 is finished, the TWS headset continues to automatically reconnect to the handset 2 once, and the number of times of reconnection becomes 1.

In an implementation manner, in the process of the TWS headset continuing to automatically reconnect to the mobile phone 2, if the TWS headset restarts processing the audio service of the mobile phone 1, that is, the TWS headset receives the audio data packet sent by the mobile phone 1 again, the TWS headset may stop automatically reconnecting to the mobile phone 2 again, or after the TWS headset automatically reconnects to the mobile phone 2 once, the TWS headset stops automatically reconnecting to the mobile phone 2, so as to avoid an influence (for example, a tone phenomenon occurs in the audio) on the audio service of the mobile phone 1 due to the TWS headset reconnecting to the mobile phone 2. And after waiting for the audio service of handset 1 to end again, the TWS headset may continue to connect back to handset 2 again.

It should be understood that, if the number of reconnection indicates the total number of times that the TWS headset automatically reconnects the mobile phone 2 since the TWS headset was disconnected from the mobile phone 2 due to a connection timeout, in the case that the mobile phone 2 continues to automatically reconnect the mobile phone 2 again, the number of reconnection corresponding to the mobile phone 2 at this time is the counted number of times that the TWS headset reconnects when the automatic reconnection of the mobile phone 2 was last stopped.

If the number of times of the reconnection indicates the total number of times that the TWS headset automatically reconnects the mobile phone 2 after the audio service of the mobile phone 1 is ended, the number of times of the reconnection corresponding to the mobile phone 2 is 0 when the mobile phone 2 automatically continues to reconnect the mobile phone 2 again.

In some embodiments, after the audio service of the handset 1 is finished, the TWS headset may determine whether to continue to automatically connect back to the handset 2 according to the recorded reason information for stopping connecting back to the handset 2. For example, if the reason information is target reason information (e.g. because the TWS headset is used by the handset 1 for audio service), then the handset 2 continues to be automatically connected back.

It was described above that a TWS headset can automatically reconnect to a handset 2 once during the course of handling the audio traffic of the handset 1 after the bluetooth connection between the TWS headset and the handset 2 has been disconnected. If the connection fails, the TWS headset may continue to automatically connect back to the mobile phone 2 multiple times after the audio service of the mobile phone 1 is finished. Another way of reconnecting will be described further below.

The TWS headset can automatically connect back to the mobile phone 2 directly after the audio service of the mobile phone 1 is finished, that is, under the condition that the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected, if the TWS headset is processing the audio service of the mobile phone 1, the TWS does not automatically connect back to the mobile phone 2, but the TWS headset starts to automatically connect back to the mobile phone only after the audio service of the mobile phone 1 is finished, thereby avoiding the influence on the audio service of the mobile phone 1.

When the TWS headset starts to automatically reconnect the mobile phone 2, the number of times of reconnection can be counted, so as to determine whether to perform next reconnection by using the number of times of reconnection.

In the embodiment of the present application, in the process that the TWS headset processes the audio service of the mobile phone 1, if the bluetooth connection between the TWS headset and the mobile phone 2 is disconnected due to connection timeout, the TWS headset automatically reconnects the mobile phone 2 once first, so as to implement timely reconnection of the mobile phone 2. And if the return is lost, the TWS headset stops automatically returning the handset 2 to avoid causing a jam of the audio traffic of the handset 1. Then, the TWS headset may continue to automatically reconnect the mobile phone 2 after the audio service of the mobile phone 1 is finished until the reconnection success or the reconnection number reaches a preset number, so as to improve the success rate of reconnecting the mobile phone 2 on the basis of avoiding affecting the audio service of the mobile phone 1.
