Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

The Bluetooth connection method provided by the embodiment of the application can be applied to electronic equipment. The electronic device may be wirelessly connected to one or more external devices (or wireless external devices) via a wireless communication technology.

The electronic device may be a terminal. The terminal is, for example, a mobile phone, a media player (e.g., MP3, MP4, etc.), a tablet computer, a notebook computer, an ultra-mobile personal computer (UMPC), a Personal Digital Assistant (PDA), a television, a smart watch, or other devices. The embodiment of the present application does not specifically limit the type of the electronic device.

The external devices can be wireless earphones, wireless sound boxes, wireless bracelets, wireless vehicles, wireless intelligent glasses, wireless watches, augmented Reality (AR)/Virtual Reality (VR) devices and the like. The embodiment of the present application does not specifically limit the type of the external device.

The wireless communication technology may be Bluetooth (BT), which may be conventional bluetooth or low-power BLE bluetooth, wireless Local Area Network (WLAN) (e.g., wireless fidelity (Wi-Fi) network), zigbee, frequency Modulation (FM), short-range wireless communication (NFC), infrared (infrared, IR), or universal 2.4G/5G band wireless communication technology, etc. The wireless connection is a connection established using the wireless communication technology. The embodiment of the present application does not specifically limit the type of the wireless communication technology.

It should be understood that the embodiments of the present application are described with respect to bluetooth connections, but may also be applicable to other wireless communication technologies.

In the embodiments of the present application, a wireless headset is used as an example of an external device. The wireless headset may be of various types, such as ear-bud, in-ear, head-mounted, earmuff, or in-ear wireless headsets. The wireless headset may include first and second portions to be worn on the user's left and right ears, respectively, and may be connected by a connecting wire, such as a neck strap wireless headset; or may be two parts independent of each other, such as a True Wireless Stereo (TWS) headset. Illustratively, when the wireless headset is a TWS headset, the first and second portions of the wireless headset may be left and right earplugs.

Fig. 1 shows an exemplary diagram of an application scenario of an embodiment of the present application. Taking the example that the electronic device is a mobile phone and the external device is an earphone, the earphone 11 is the device to which the mobile phone 10 is connected last time. After the bluetooth function is turned on, the mobile phone 10 will automatically connect back to the earphone 11 that was connected last time. The headset 11 is no longer currently within communication range of the handset 10 (e.g., the headset 11 is off or not near the handset 10).

As shown in (1) in fig. 1, a bluetooth management interface of the mobile phone 10 is displayed in the interface. When the bluetooth function of the handset 10 is turned on, the "bluetooth is currently discoverable by nearby bluetooth devices" option is on. With this option in the open state, the handset 10 may perform bluetooth related functions such as search, pairing, connecting devices, etc.

As shown in fig. 1 (1), a "paired devices" column is included in the interface. The paired device column is used to display the devices that have been paired with the handset 10. The "paired device" shows that the headset 11 is connected.

In addition, during the automatic connection back of the headset 11, the mobile phone 10 can also scan synchronously to find other available devices. For example, as shown in (1) in fig. 1, the scanned headphones 12 are displayed in the available device column. In the connection process of the earphone 11, if the user actively clicks to connect the earphone 12, the connection of the earphone 12 can be performed after the automatic reconnection of the earphone 11 is over time. After waiting for a period of time, the headset 11 fails to connect and the handset 10 interface is shown as (2) in fig. 1.

As shown in (2) of fig. 1, the earphone 11 is automatically lost, and the interface of the mobile phone 10 pops up a window 13, and the window 13 is used for prompting the user that the earphone 11 is failed to connect.

Illustratively, the reason for the connection failure may be displayed in the window 13: the device bluetooth is off, or not within communication range (10 meters). Window 14 may also be included in window 13. "known" is displayed in the window 14. After the user reads the content prompted by the window 13, the window 14 may be clicked. After clicking on window 14, window 13 may be closed.

Optionally, as shown in (1) in fig. 1 or (2) in fig. 1, an option of "device name" may also be displayed in the interface, for example, the current device name is "glory", that is, the name of the mobile phone 10 is glory.

Optionally, as shown in (1) in fig. 1 or (2) in fig. 1, an option of "received file" may also be displayed in the interface. The "received files" option refers to files sent by other devices that the handset 10 receives via bluetooth.

It should be understood that the interface shown in fig. 1 is only an exemplary description, and the embodiments of the present application are not limited thereto. In fact, more or fewer options or controls may be included in the interface described above.

It should be further understood that fig. 1 illustrates an example where both the external devices are earphones, and the embodiments of the present application are not limited thereto. For example, the above-mentioned headset 11 and/or headset 12 may be replaced by other bluetooth peripherals, etc. For another example, the paired device bar or the available device bar of the mobile phone 10 may include a greater number of external devices.

It should also be understood that the scenario in fig. 1 is only a schematic illustration of an application scenario of the present application, which does not limit the embodiments of the present application, and the present application is not limited thereto.

It should also be understood that, the embodiment of the present application does not specifically limit how to enter the bluetooth management interface. For example, the user may click on a setup application and then click on a bluetooth option in the setup application to enter a bluetooth management interface, such as the bluetooth management interface shown in (1) of fig. 1.

Typically, an external device (e.g., the headset 11) will attempt to make two connections. The connection timeout resulting from these two connections is an appointment lasting several seconds (e.g., 16 seconds). During this period, if the user actively connects another external device (such as the headset 12), the user needs to wait until the connection back process of the headset 11 is finished, and then the connection between the other external device (such as the headset 12) and the electronic device (such as the mobile phone 10) can not be established, which results in that the connection speed of the headset 12 is very slow, and the user experience is seriously affected.

In view of this, the embodiment of the present application provides a bluetooth connection method, in a connection process of a second external device (for example, an earphone 11), if an electronic device detects an operation request for a user to connect to a first external device (for example, an earphone 12), the connection of the second external device is cancelled, and a connection between the electronic device and the first external device is established, so that the connection of the first external device can be accelerated. For the situation that the second external device needs to wait for connection timeout due to the fact that the second external device is not in the communication range, the timeout time does not need to be waited for any more, the connection speed of the first external device is remarkably improved, and user experience is improved.

Fig. 2 is a view showing one configuration example of the earphone. As shown in fig. 2, the wireless headset 100 includes at least one processor 101, at least one memory 102, a wireless communication module 103, an audio module 104, a power supply module 105, an input/output interface 106, and the like.

For example, when the bluetooth headset receives the connection request information of the electronic device, the bluetooth headset may establish a physical connection with the electronic device.

The processor 101 may include one or more processing units, and different processing units may be independent devices or may be integrated in one or more of the processors 101. The processor 101 may be specifically an integrated control chip, or may be composed of a circuit including various active and/or passive components, and the circuit is configured to execute the functions belonging to the processor 101 described in the embodiments of the present application.

The wireless communication module 103 may be configured to support data exchange between the wireless headset 100 and other electronic devices or headset cases, including BT, WLAN (e.g., wi-Fi), zigbee, FM, NFC, IR, or general 2.4G/5G wireless communication technologies.

In some embodiments, the wireless communication module 103 may be a bluetooth chip. The wireless headset 100 can be paired with bluetooth chips of other electronic devices through the bluetooth chip and establish a wireless connection, so as to implement wireless communication and service processing between the wireless headset 100 and the other electronic devices through the wireless connection. The wireless connection may be a physical connection or a virtual connection. Generally, a bluetooth chip may support Basic Rate (BR)/enhanced rate (EDR) bluetooth and BLE, for example, paging (page) information may be received/transmitted, BLE broadcast messages may be received/transmitted, and the like.

In addition, the wireless communication module 103 may further include an antenna, and the wireless communication module 103 may receive an electromagnetic wave via the antenna, frequency-modulate and filter an electromagnetic wave signal, and transmit the processed signal to the processor 101. The wireless communication module 103 may also receive a signal to be transmitted from the processor 101, perform frequency modulation and amplification on the signal, and convert the signal into electromagnetic waves through an antenna to radiate the electromagnetic waves.

The audio module 104 may be used to manage audio data and enable the wireless headset 100 to input and output audio signals. For example, the audio module 104 may obtain an audio signal from the wireless communication module 103 or transmit the audio signal to the wireless communication module 103, so as to implement functions of making and receiving calls through a bluetooth headset, playing music, activating/deactivating a voice assistant of an electronic device connected to the headset, receiving/transmitting voice data of a user, and the like. The audio module 104 may include a speaker (or called an earphone or a receiver) component for outputting an audio signal, a microphone (or called a microphone or a microphone), a microphone receiving circuit matched with the microphone, and the like. The speaker can be used to convert the audio electrical signal into a sound signal and play the sound signal. The microphone may be used to convert sound signals into electrical audio signals.

The power module 105 may be configured to provide a system power for the wireless headset 100 to supply power to each module of the wireless headset 100; the wireless headset 100 is supported to receive a charging input, etc. The power module 105 may include a Power Management Unit (PMU) and a battery. The power management unit can receive external charging input; the electric signal input by the charging circuit is provided for the battery to charge after being transformed, and the electric signal provided by the battery can be provided for other modules such as the audio module 104, the wireless communication module 103 and the like after being transformed; and to prevent overcharging, overdischarging, short-circuiting, overcurrent, etc. of the battery. In some embodiments, the power module 105 may also include a wireless charging coil for wirelessly charging the wireless headset 100. In addition, the power management unit can also be used for monitoring parameters such as battery capacity, battery cycle number, battery health state (leakage, impedance) and the like.

A plurality of input/output interfaces 106 may be used to provide a wired connection for charging or communication between the wireless headset 100 and a headset case. In some embodiments, the input/output interface may be a USB interface. In other embodiments, the input/output interface 106 may be a headset electrical connector through which the wireless headset 100 may establish electrical connection with an electrical connector in a headset case when the wireless headset 100 is placed in the headset case, thereby charging a battery in the wireless headset 100. In other embodiments, after the electrical connection is established, the wireless headset 100 may also be in data communication with a headset box, for example, may receive a pairing instruction from the headset box.

In addition, the wireless headset 100 may also include a sensor 107. For example, the sensor 107 may be a distance sensor or a proximity light sensor that may be used to determine whether the wireless headset 100 is worn by a user. For example, the wireless headset 100 may determine whether the wireless headset 100 is worn by the user by using a distance sensor to detect whether an object is near the wireless headset 100. Upon determining that the wireless headset 100 is worn, the wireless headset 100 may turn on the speaker. As another example, the sensor 107 may also include a bone conduction sensor, incorporated into a bone conduction headset. By using the bone conduction sensor, the wireless earphone 100 can acquire the vibration signal of the vibration bone mass of the human body vocal part, analyze the voice signal, realize the voice function, and thus receive the voice command of the user. The wireless headset 100 may also perform voice authentication according to the user voice signal acquired by the bone conduction headset, so as to authenticate the user identity in a service scenario such as payment transaction. For another example, the sensor 107 may further include: a touch sensor for detecting a touch operation of a user; the fingerprint sensor is used for detecting the fingerprint of the user, identifying the identity of the user and the like; the ambient light sensor can adaptively adjust some parameters (such as volume) according to the perceived brightness of the ambient light; and other sensors.

In some embodiments, the touch sensor may detect a single click, a double click, multiple clicks, a long press, a heavy press, and other touch operations of the user, and may perform user fingerprint recognition to authenticate the user identity in a service scenario such as a payment transaction.

The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then passes the demodulated low frequency baseband signal to a baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. The application processor outputs sound signals through an audio device (not limited to the speaker 370A, the receiver 370B, etc.) or displays images or video through the display 394. In some embodiments, the modem processor may be a stand-alone device. In other embodiments, the modem processor may be separate from the processor 310, and may be disposed in the same device as the mobile communication module 350 or other functional modules.

The wireless communication module 360 may provide a solution for wireless communication applied to the electronic device 300, including WLAN (e.g., wi-Fi), BT, global Navigation Satellite System (GNSS), FM, NFC, IR, or universal 2.4G/5G wireless communication technologies. The wireless communication module 360 may be one or more devices integrating at least one communication processing module. The wireless communication module 360 receives electromagnetic waves via the antenna 2, performs frequency modulation and filtering processing on electromagnetic wave signals, and transmits the processed signals to the processor 310. The wireless communication module 360 may also receive a signal to be transmitted from the processor 310, frequency-modulate and amplify the signal, and convert the signal into electromagnetic waves via the antenna 2 to radiate the electromagnetic waves.

In some embodiments, the wireless communication module 360 may be a bluetooth chip. The electronic device 300 may pair with a bluetooth chip of an electronic device such as a wireless headset through the bluetooth chip and establish a wireless connection, so as to implement wireless communication and service processing between the electronic device 300 and other electronic devices through the wireless connection. The wireless connection may be a physical connection or a virtual connection. The Bluetooth chip can generally support BR/EDR Bluetooth and BLE.

The electronic device 300 may implement display functionality through the GPU, the display screen 194, and the application processor. The GPU is a microprocessor for image processing, connected to the display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. The processor 310 may include one or more GPUs that execute program instructions to generate or alter display information.

The display screen 394 may be used to display images or video. The display screen 394 includes a display panel. The display panel may adopt a Liquid Crystal Display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a Mini light-emitting diode (Mini LED), a Micro light-emitting diode (Micro LED), a Micro OLED (Micro OLED), or a quantum dot light-emitting diode (QLED). In some embodiments, the electronic device 300 may include 1 or N display screens 394, N being a positive integer greater than 1.

Electronic device 300 may implement the camera functions through the ISP, camera 393, video codec, GPU, display 394, application processor, etc.

The ISP is used to process the data fed back by the camera 393. For example, when a user takes a picture, the shutter is opened, light is transmitted to the camera photosensitive element through the lens, an optical signal is converted into an electric signal, and the camera photosensitive element transmits the electric signal to the ISP for processing and converting into an image visible to the naked eye. The ISP can perform algorithm optimization on the noise, brightness and color of the image, and can also optimize parameters such as exposure, color temperature and the like of a shooting scene. In some embodiments, the ISP may be located in camera 393.

The camera 393 is used to capture still images or video. The object generates an optical image through the lens and projects the optical image to the photosensitive element. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into a standard Red Green Blue (RGB), YUV, or the like format image signal. In some embodiments, electronic device 300 may include 1 or N cameras 193, N being a positive integer greater than 1.

The digital signal processor is used for processing digital signals, and can process digital image signals and other digital signals. For example, when the electronic device 300 selects a frequency bin, the digital signal processor is used to perform fourier transform or the like on the frequency bin energy.

The electronic device 300 may implement audio functions, such as music playing and recording, through the audio module 370, the speaker 370A, the receiver 370B, the microphone 370C, the earphone interface 370D, and the application processor.

The audio module 370 is used to convert digital audio information into an analog audio signal for output, and may also be used to convert an analog audio input into a digital audio signal. The audio module 370 may also be used to encode and decode audio signals. In some embodiments, the audio module 370 or some functional modules of the audio module 370 may be disposed in the processor 310.

The speaker 370A, also called a horn, converts an audio electric signal into a sound signal. The electronic device 300 can listen to music or a handsfree call through the speaker 370A.

The receiver 370B, also called an earpiece, is used to convert the electrical audio signal into a sound signal. When a user answers a call or voice information using electronic device 300, voice can be answered by placing receiver 370B close to the ear.

The microphone 370C, also referred to as a microphone or microphone, is used to convert sound signals into electrical signals. When a user places a call or sends a voice message, a voice signal may be input into the microphone 370C by sounding near the microphone 370C.

The earphone interface 370D is used to connect a wired earphone. The headset interface 370D may be the USB interface 330, or may be an Open Mobile Terminal Platform (OMTP) standard interface of 3.5mm, a cellular telecommunications industry association (cellular telecommunications industry association) standard interface of the USA.

Keys 390 include a power-on key and a volume key. The keys 390 may be mechanical keys or touch keys. The electronic device 300 can receive the key input signal and implement the function related to the case input signal.

The motor 391 may generate vibrations. The motor 391 may be used for incoming call alerting, as well as for touch feedback. The motor 391 may generate different vibration feedback effects on touch operations applied to different applications. The motor 391 may also produce different vibration feedback effects for touch operations that are applied to different areas of the display screen 394. Different application scenarios (e.g., time reminders, received information, alarms, and games) may correspond to different vibration feedback effects. The touch vibration feedback effect may also support customization.

The connection relationship between the modules shown in fig. 3 is only for illustrative purposes and does not limit the connection relationship between the modules of the electronic apparatus 300. Alternatively, the modules of the electronic device 300 may also adopt a combination of multiple connection manners in the above embodiments.

The hardware system of the electronic device 300 is described above in detail, and the software system of the electronic device 300 is described below. The software system may adopt a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture or a cloud architecture, and the embodiment of the present application takes the layered architecture as an example to exemplarily describe the software system of the electronic device 300.

Fig. 4 is a schematic diagram of a software system suitable for use in the electronic device of the present application. As shown in fig. 4, the software system adopting the layered architecture is divided into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the software system may be divided into four layers, which are an application layer, an application framework layer, a native service layer, a Hardware Abstraction Layer (HAL), and a physical layer from top to bottom.

Wherein the application layer may include a series of application packages. The setup application and bluetooth application are shown in fig. 4. For example, the application layer may further include applications such as a camera, a gallery, a calendar, a call, a map, navigation, WLAN, music, video, and a short message.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer may include some predefined functions. As shown in fig. 4, the application framework layer includes a bluetooth service.

Optionally, the application framework layer may also include a window manager, a content provider, a view system, a phone manager, a resource manager, and a notification manager.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen and judge whether a status bar, a lock screen and a capture screen exist.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and answered, browsing history and bookmarks, and phone books.

The view system includes visual controls such as controls to display text and controls to display pictures. The view system may be used to build applications. The display interface may be composed of one or more views, for example, a display interface including a short message notification icon, and may include a view displaying text and a view displaying pictures.

The phone manager is used to provide communication functions of the electronic device 300, such as management of call status (on or off).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, and video files.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as notification managers, are used for download completion notifications and message reminders. The notification manager may also manage notifications that appear in a chart or scrollbar text form in a status bar at the top of the system, such as notifications for applications running in the background. The notification manager may also manage notifications that appear on the screen in dialog windows, such as prompting for text messages in a status bar, sounding a prompt tone, vibrating the electronic device, and flashing an indicator light.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system.

The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. The virtual machine executes java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform the functions of object lifecycle management, stack management, thread management, security and exception management, and garbage collection.

And a Native layer can improve some local services, link libraries and the like. Wherein, the Native layer may comprise a bluetooth protocol stack. In other embodiments, the bluetooth connection method provided in the embodiments of the present application may also be implemented by adaptively modifying a bluetooth protocol stack in a Native layer. In some embodiments, the bluetooth protocol stack may include a queue module. A node (node) generated based on the bluetooth connection request may be included in the queue module. For example, when the electronic device 300 automatically connects back to the second external device, the node 1 and the node 2 are generated in the queue. The node 1 is used for processing a call connection request of the second external device, and the node 2 is used for processing a media (such as music) connection request of the second external device. For example, the queues are sorted according to the order of node 1 and node 2.

In the embodiment of the present application, if, in the automatic reconnection process of the second external device, the electronic device receives a connection request of the first external device, where the first external device is a preferential connection device, and the connection request of the first external device is processed by the node 3, in a queue, the node 3 is arranged in front of the node 1 and the node 2, and the request of the node 3 is preferentially processed, that is, the first external device is preferentially connected. For example, the queues are sorted according to the order of node 3, node 1, and node 2. In addition, after the connection of the first external device is completed, the second external device can be continuously connected, that is, after the processing of the node 3 is completed, the node 1 and the node 2 are continuously processed.

It should be understood that node 1, node 2, and node 3 are only described here as examples, and the embodiments of the present application are not limited thereto. In fact, more nodes may be included in the queue.

The HAL layer is an interface layer between the operating system kernel and the hardware circuitry, which abstracts the hardware. The physical layer provides the underlying hardware driver interface.

The kernel layer is a layer between hardware and software. The kernel layer can comprise driving modules such as a display driver, a camera driver, an audio driver and a sensor driver.

It is understood that the electronic device 300 may also be other operating systems, and the embodiments of the present application are not limited thereto. In other operating systems, the framework layer and the Native layer may be configured as one layer. Therefore, in other embodiments, the bluetooth connection method provided in the embodiment of the present application may also be implemented by performing a corresponding modification on the existing bluetooth protocol in this layer.

It should be noted that, the above only illustrates the structure of the electronic device with reference to fig. 3, and the software architecture of the electronic device with reference to fig. 4, which is not specifically limited in this embodiment of the present application.

The bluetooth Service in the framework layer will be described as an example. In the bluetooth protocol based on the embodiment of the present application, when determining that the bluetooth Service in the electronic device framework layer is paired with a bluetooth headset and receiving a BLE broadcast message sent by the bluetooth headset, the bluetooth Service reports that the bluetooth Service is connected to the bluetooth headset to an upper layer bluetooth application (e.g., a bluetooth setting application). For example, the bluetooth Service in the framework layer may specifically notify the bluetooth setting application that the bluetooth headset is connected to the bluetooth Service application through an android broadcast message mechanism. The upper layer bluetooth application displays relevant information of the connected bluetooth headset on a relevant interface (for example, in a status bar of a display interface, or in a notification bar, or on a bluetooth management interface, or on a minus 1 screen, etc.), such as connected information of power, wearing status, service status, connection status, device name, device model, device icon, connection identifier, etc. The BLE broadcast message may include one of the device name, the device type, the device model, the battery level, the wearing state, the connection state, the traffic state, and other operating state information of the bluetooth headset. Wherein the connection state information may indicate whether a physical connection has been established with the electronic device. The service status information may indicate whether the bluetooth headset is currently in an idle state or not, or an audio service being processed by the bluetooth headset. Moreover, the BLE broadcast message is sent periodically, and the bluetooth application may update the related information of the connected bluetooth headset displayed on the related interface in real time according to the state information of the bluetooth headset in the BLE broadcast message acquired in real time.

The method of bluetooth connection according to the embodiment of the present application is described in detail below with reference to fig. 5 to 9. The embodiment of the application is described by taking the example that the electronic equipment and the external equipment comprise the Bluetooth module and the electronic equipment and the external equipment are in wireless connection through Bluetooth.

Referring to fig. 5, fig. 5 is a diagram illustrating an example of a method 500 for determining a priority connection device according to an embodiment of the present application. It is to be understood that the method of fig. 5 may be applied to an electronic device. For example, in the scenario shown in fig. 1. The method 500 in fig. 5 includes the following steps:

step 501, the electronic device turns on bluetooth.

The embodiment of the application does not specifically limit the entrance for the electronic device to open the bluetooth. For example, the user may slide down the notification bar (or status bar) and then click a bluetooth control in the notification bar to activate the bluetooth function. For another example, the user may enter a bluetooth function switch option in a setting application or a bluetooth application of the electronic device, and select to start the bluetooth function.

Step 502, the electronic device performs automatic loopback and simultaneously starts scanning.

Illustratively, the electronic device actively attempts to connect to the recently connected device (or the last connected device) after the bluetooth function is turned on. The embodiment of the application names the equipment which is connected recently as the second external equipment. The second external device is, for example, the earphone 11 shown in fig. 1.

The electronic device may also initiate a scan synchronously while performing an automatic reconnect to discover other connectable external devices. For example, the electronic device scans to the first external device. Scanning may also be understood as the process of searching for or discovering new devices.

Step 503, the electronic device discovers the first external device.

For example, the first external device may be the headset 12 shown in FIG. 1.

The embodiment of the present application does not specifically limit how the electronic device discovers the first external device. The electronic device can discover the first external device in a BR scanning mode and also can discover the first external device in a BLE broadcasting mode.

Optionally, as an implementation manner, the electronic device discovers the first external device in a BLE broadcast manner, which is specifically as follows:

the method comprises the steps that a first external device broadcasts a Bluetooth Low Energy (BLE) broadcast message of an electronic device, wherein the BLE broadcast message comprises a Bluetooth address; accordingly, after receiving the BLE broadcast message, the electronic device obtains the Bluetooth address by analyzing the BLE broadcast message.

Optionally, the BLE broadcast message may be periodically transmitted by the first peripheral device.

It should be understood that other information may also be included in the BLE broadcast message, and this embodiment of the present application is not limited in this respect.

Optionally, as an implementation manner, the discovering, by the electronic device, the first external device through BR scanning includes:

the electronic equipment sends a query (inquiry) request to the first external equipment;

and the first external equipment replies response request information to the electronic equipment, wherein the response request information comprises a basic rate BR address.

After the electronic device receives the response request information, it can know that the first external device is scanned.

It should be understood that the two ways of discovering the first peripheral device shown above are only exemplary descriptions, and the embodiments of the present application are not limited thereto. In fact, the electronic device may also discover the first external device in other reasonable manners.

After the first external device is scanned, the electronic device may perform a matching operation with the first external device based on the analyzed bluetooth address.

Illustratively, after receiving the BLE broadcast message, the electronic device parses the BLE broadcast message to obtain a bluetooth address, and pairs (or matches) with the first external device based on the bluetooth address and the pairing list device.

Pairing refers to sharing a link key (link key) between the electronic device and the first external device. The link key may be used to mutually authenticate the bluetooth devices and encrypt the exchanged data. For example, the pairing mode of the bluetooth device may include PIN code pairing (PIN code pairing) and Secure Simple Pairing (SSP).

When the electronic device is successfully paired with the first external device, the first external device can be considered to be in a paired state. Meanwhile, whether the first external equipment can be connected or not can be judged. The connectable state may be understood as a state in which the first external device is capable of being connected.

Step 504, determining whether the first external device is in a connectable and paired state.

Exemplarily, the paired state may be understood as: the first external equipment can be searched by the electronic equipment, and the electronic equipment and the first external equipment are successfully paired.

In some possible implementations, the connectable state may be determined based on a maximum number of devices that the first add-on device supports connections. For example, the first external device supports at most 2 devices, and if the first external device is connected to one device, which indicates that the first external device can be further connected, the first external device is in a connectable state.

If the first external device is in a connectable and paired state, step 504 is performed. If the first external device is not in a connectable state or a paired state, step 504 is not performed.

Optionally, after the first external device is discovered, the electronic device may further display a first window (or a first pop-up window) to prompt the user that the first external device is connectable.

Optionally, the method 500 further comprises:

After the first external device is in a connectable and paired state, the user may be prompted through the first window that the first external device is connectable. The first interface may be an interface as shown in (1) in fig. 8 later, and the first window may be the window 801 in (1) in fig. 8.

Optionally, the first window may further include an option or a control for connecting the first external device. And when the user clicks the option for connecting the first external equipment in the first window, the connection of the first external equipment can be initiated. An example of the first window will be described as an example of the interface in fig. 8, which follows.

Step 505, the electronic device sets the first external device as a priority connection device.

In the embodiment of the application, the electronic device marks the first external device as a device preferentially connected. The preferentially connected devices are: the connection order is better than the device to which the electronic device is currently connected (e.g., the device that is automatically reconnecting).

It should be understood that the embodiment of the present application does not limit the specific marking manner of the device for marking the preferential connection.

For example, in a case that the first external device is successfully paired, identification information may be added to the pairing information of the first external device, where the identification information is used to identify that the first external device is a device that allows preferential connection.

For example, in a case that the first external device is not paired, the first external device may be set as a priority connection device in a process of connecting the first external device based on a BLE result temporarily cached locally by the electronic device.

According to the embodiment of the application, the first external equipment is set as the priority connection equipment, so that a user can conveniently realize the quick connection of the first external equipment. The connection process of the first external device is described below with reference to fig. 6.

Referring to fig. 6, fig. 6 shows a schematic flow chart of a method 600 for bluetooth connection in an embodiment of the present application. It is to be understood that the method of fig. 6 may be applied to an electronic device. For example, in the scenario shown in fig. 1. It should also be understood that the method in fig. 6 may be implemented in combination with the method in fig. 5, or may be implemented independently, which is not particularly limited. Illustratively, when the method of fig. 5 is implemented in combination with the method of fig. 6, the method of fig. 5 may be performed first, and then the method of fig. 6 may be performed.

As shown in fig. 6, the method 600 includes the steps of:

step 601, detecting a first operation of a user, where the first operation is used to instruct to initiate bluetooth connection of a first external device.

The first operation may be an operation of connecting the first external device, which is manually initiated by a user. The embodiment of the present application does not limit the specific form of the first operation.

The first operation may be initiated at the electronic device side, or may be initiated at the first external device, which is not particularly limited.

In one implementation, a user may click on a first external device in an electronic device. For example, the above description of step 504 in fig. 5 refers to "when the user clicks the option of connecting to the first external device in the first popup, the connection to the first external device may be initiated", that is, the first operation may be that the user clicks the option of connecting to the first external device in the first popup. For example, the first operation may be an operation of clicking on the "yes" option in window 801 in FIG. 8.

In another implementation manner, the user may initiate bluetooth connection by touching the touch operation area of the first external device. The embodiments of the present application do not limit this.

The embodiment of the present application does not specifically limit how the electronic device discovers the first external device.

Step 602, determining whether a second external device is currently connected.

Optionally, the second external device is an automatic back-connection device of the electronic device.

The reconnection refers to an operation in which the electronic device is attempting to perform reconnection with a previously paired and connected second external device by means of paging. In some embodiments, the back-joining comprises: the electronic device sends a paging (page) packet to the second external device to request establishment of a communication connection with the second external device.

Or, optionally, the second external device is a device that the user selects to connect before initiating the first operation, and the second external device cannot establish a connection with the electronic device currently. Illustratively, before detecting the first operation of the user, the electronic device further detects a second operation, and the second operation is used for indicating that a second external device is connected.

Illustratively, the second external device is unable to establish a connection with the electronic device, including one or more of: the second external equipment is in a power-off state and cannot be connected with the electronic equipment; the second external device is far away from the electronic device, is not in the communication range of the electronic device and cannot receive data sent by the electronic device; the second external device establishes connection with other devices, and exceeds the maximum connection quantity, so that connection with the electronic device can not be established.

It should be understood that the above description about the case where the second external device cannot establish connection with the electronic device is only an exemplary description, and the embodiments of the present application are not limited thereto.

If the electronic device is being connected to the second external device, step 603 is executed to determine whether the first external device is a preferred connection device. It is described herein that the first operation by the user is detected in a case where the electronic apparatus is being connected to the second external apparatus. Of course, if the electronic device is not connected to the second external device, the electronic device may directly initiate connection to the first external device after detecting the first operation of the user.

Step 603, in a case that the second external device is being connected, determining whether the first external device is a priority connection device.

A preferentially connected device refers to a device (such as a second external device) that is connected in a better order than the device to which the electronic device is currently connected.

The preferred connection device may be set as described above with reference to step 504 of fig. 5. For brevity, no further description is provided herein.

For example, when the first external device is set as the preferred external device in step 504 in fig. 5, it can be determined that the first external device is the preferred connection device, that is, the connection of the first external device is better than the connection of the second external device.

Step 604, in response to the first operation, when it is determined that the first external device is the priority connection device, canceling the connection of the second external device, and establishing a bluetooth connection between the electronic device and the first external device.

For example, the cancellation of the connection of the second external device may be understood as: and for the second external equipment which is connected, canceling or terminating the physical link connection of the second external equipment.

Optionally, after the connection between the first external device and the electronic device is completed, if the connection of the second external device needs to be restored, the connection of the second external device may be continuously attempted.

In the embodiment of the application, after a first operation of a user is detected, whether a second external device which is being connected exists is judged; judging whether the first external equipment is priority connection equipment or not under the condition that the second external equipment is connected; under the condition that the first external equipment is the preferential connection equipment, the second external equipment is cancelled and the Bluetooth connection with the first external equipment is established, so that the connection speed and the connection power of the first external equipment can be obviously improved. Under the condition that the second external device cannot be successfully connected, the connection speed of the first external device can be obviously increased on the premise of keeping the automatic reconnection function.

Of course, if the first external device is not the preferential connection device, the connection request of the first external device may be added into the queue, and connection may be performed in sequence according to the queue order, for example, after the connection of the second external device is overtime or finished, the first external device is connected.

The following is described by way of example in connection with the flow in fig. 7. It should be understood that some of the features, terms, or concepts referred to in FIG. 7 may be referred to in the foregoing description and will not be described in detail below. Taking the first external device as a example and the second external device as a device B as an example, as shown in fig. 7, the method includes the following steps:

in step 701, a user requests to connect to device a.

In step 702, the electronic device determines whether another device (e.g., device B) is currently connected.

If device B is connecting, then step 703 is performed; if no other devices are connecting, step 704 is performed.

In step 703, the electronic device determines whether device a is a priority connection device.

If device a is a priority connection device, step 705 is performed. If device a is not a priority connection device, step 707 is performed.

In step 704, the electronic device directly initiates the connection of device a.

Step 705, the electronic device cancels the connection of device B and establishes the connection of device a.

For example, when it is determined that the device a is a device to which connection is prioritized, the connection of the device B is cancelled, and the connection of the device a is immediately initiated.

Optionally, after step 705 is performed, step 706 may also be performed, i.e. continue to connect device B.

In step 707, the electronic device enqueues the connection request of device a in the queue and performs the connection of device B.

In step 708, after the connection time out or end of the device B, the connection of the device a is executed.

It should be understood that the flow of fig. 7 is only an exemplary description, and the embodiments of the present application are not limited thereto. In fact, the above-described flow can be implemented by more steps or fewer steps on the basis of fig. 7 by those skilled in the art.

Optionally, after the bluetooth connection between the electronic device and the first external device is established, the method 600 further includes:

That is to say, after the first external device is successfully connected with the electronic device, the user can be prompted on the interface that the first external device is successfully connected, so that the user can intuitively know that the first external device is successfully connected.

It can be understood that other information may also be displayed in the second interface, and this is not particularly limited in this embodiment of the application.

The following is described in connection with the interface examples in fig. 8 and 9.

Referring to fig. 8, fig. 8 illustrates an example diagram of an interface according to an embodiment of the present application. As shown in (1) in fig. 8, a bluetooth management interface of the mobile phone 10 is displayed in the interface. The interface shown in (1) in fig. 8 is similar to the interface shown in (1) in fig. 1, and details of the interface are not repeated here.

After the method of bluetooth connection according to the embodiment of the present application is adopted, as shown in (1) in fig. 8, when the headset 11 is automatically connected back, if the headset 12 is successfully paired with the mobile phone 10, a window 801 (corresponding to the foregoing first window) may pop up in the interface of the mobile phone 10. The window 801 includes options of "yes" and "no". The window 801 is used to prompt the user to scan whether the headset 12 is connectable or not connected. If the user clicks the "Yes" option in window 801, the interface displays an interface as shown in (2) of FIG. 8. In contrast to fig. 1 shown above, the headset 12 in fig. 8 does not need to wait for the headset 11 to be connected for a time-out before establishing a connection with the handset 10. Therefore, the interface of (2) in fig. 8 does not show the connection failure window 13 shown in (2) in fig. 1.

It should be understood that the options included in the window 801, the position of the window 801 in the interface, and the size of the window 801 are only exemplary descriptions, and the embodiment of the present application is not limited thereto.

Illustratively, the first operation of the foregoing step 601 may be that the user clicks the "yes" option in the window 801.

As shown in the interface (2) in fig. 8, the headphone 12 shows that it is being connected, and the headphone 11 is located below the headphone 12. That is, the handset 10 cancels the connection of the earphone 11 and initiates the connection of the earphone 12 after detecting the connection request of the user for the earphone 12, so as to meet the requirement of the user to connect the earphone 12.

When the headset 12 and the mobile phone 10 are connected, the interface of the mobile phone 10 may display an interface (corresponding to the second interface) as shown in (3) in fig. 8. As shown in fig. 8 (3), in the paired device bar, the headphones 12 display the connected (corresponding to the prompt information in the second interface). In addition, a control 901 may be further included in the bluetooth interface of the mobile phone 10. Controls 901 are used to access the management interface of the headset 12. Similarly, corresponding controls may also be provided for the headset 11.

In some embodiments, the bluetooth application or setup application may also display information such as the name of bluetooth, the device type, the device model, the power level of the device, etc. on the interface of the electronic device.

As shown in (1) in fig. 9, the user can click on a control 901 to set the headset 12. After the cell phone 10 detects that the user clicks the control 901, the interface is as shown in (2) in fig. 9. As shown in (2) in fig. 9, detailed information of the bluetooth headset 12 may be displayed in the interface of the mobile phone 10. The detailed information may include: a rename option, a call audio switch option, a media audio switch option, a bluetooth automatic connect switch option, power information (including left and right earphones), a ring tone synchronization switch option, a unpairing window, etc.

The rename option is used to modify the name of the headset 12. When the user clicks on the rename option, the name of the headset 12 may be edited or modified.

The call audio switch option is used to select whether the call audio of the handset 10 is played through the bluetooth headset. For example, when the user opens the call audio option, the call audio of the mobile phone 10 can be played through the earphone 12; when the user closes the call audio option, the call audio of the mobile phone 10 is not played through the earphone 12.

The media audio switch option is used to select whether the media audio of the handset 10 is played through the bluetooth headset. For example, when the user opens the media audio option, the media audio of the mobile phone 10 can be played through the earphone 12; when the user closes the media audio option, the media audio of the handset 10 is not played through the headphones 12.

The bluetooth automatic connect switch option is used to select whether to automatically connect the bluetooth headset. For example, when the user turns on the bluetooth automatic connection switch option, if the headset 12 is found, the mobile phone 10 automatically connects the headset 12.

The ring tone synchronization switch option is used to select whether the headset 12 automatically plays the ring tone of the phone when an incoming call is made.

The unpairing window is used to select whether or not to unpair the current headset 12.

It should be understood that the interfaces shown in fig. 8 and 9 are only exemplary descriptions, and the embodiments of the present application are not limited to this scenario.

Optionally, after the headset 12 establishes a connection with the handset 10, status information of the connected bluetooth headset may also be displayed on the handset. In one implementation, the bluetooth application or setup application may display status information of the connected bluetooth headset on the interface of the handset 10. For example, in the bluetooth management interface shown in (3) in fig. 8 or the bluetooth management interface shown in (1) in fig. 9, the connected information of the headset 12 is displayed below the paired device bar. For another example, a connection icon and a power identifier of the headset 12 may be displayed in a status bar of the mobile phone. The embodiment of the present application is not particularly limited to this.
