Detailed Description

In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

Among them, in the bluetooth Protocol stack, a Service Discovery Protocol (SDP), also called bluetooth SDP, is used to provide specific meanings of applications in the bluetooth environment, and is used to discover which services are available and to determine the features of the available services. SDP defines a method by which an electronic device discovers available bluetooth server services and features. Wherein the PDU of each SDP includes a PDU Header (Header) and a PDU specific Parameter (Parameter); the PDU header includes three fields: PDU identifier (PDU ID), Transaction identifier (Transaction ID), and Parameter Length (Parameter Length).

Currently, electronic devices can be connected by means of bluetooth. However, in the process of performing bluetooth connection with another electronic device each time, an SDP procedure needs to be performed on each designated connection (connection based on profile) to discover some service attribute values of the profile corresponding to the designated connection by the other electronic device, which results in a long time consuming process of bluetooth connection. The inventor finds that, each time when the bluetooth connection is established, the upper layer profile based on the bluetooth link needs to perform the SDP procedure first and then perform the connection of the profile layer, so that if a plurality of profiles are run on a certain electronic device and another electronic device, the SDP procedure may be executed for a plurality of times, and further, the time consumption of the bluetooth connection may be increased.

In view of the above problems, the inventors have found through long-term research and propose a device connection method, an apparatus, an electronic device, and a storage medium provided in the embodiments of the present application, and simplify a subsequent process in a connection process based on a specific configuration file by locally storing SDP data of the specific configuration file, thereby increasing a speed of bluetooth connection. Specific device connection methods are described in detail in the following embodiments.

The following description is directed to an application environment that can be used in the device connection method provided in the embodiments of the present application.

As shown in fig. 1, the first electronic device 100 may be a user terminal (e.g., may be a smart phone), the second electronic device 200 may be a smart home device, and the smart home device may include an electronic device such as a smart television, an air conditioner, a curtain, and the like, and when the first electronic device 100 is close to the second electronic device 200 and the first electronic device 100 and the second electronic device 200 are within a certain distance range, the first electronic device 100 and the second electronic device 200 may perform a bluetooth connection. Wherein, if the first electronic device 100 and the second electronic device 200 have been bluetooth connected before, the first electronic device 100 and the second electronic device 200 may be connected back. The loopback refers to that the first electronic device 100 sends a page packet to the second electronic device 200 to request to establish a communication connection with the second electronic device 200, where the page is usually called connection (paging), and the operation of connecting/activating the second electronic device 200 is called page, specifically, the page refers to that the device (the first electronic device) initiating the connection knows the address of the device (the second electronic device) to be connected, so that the page can be directly paged.

As shown in fig. 2, the first electronic device 100 may be a user terminal (e.g., may be a smart phone), the second electronic device 200 may be a true wireless bluetooth headset (TWS) device, and when the second electronic device 200 is close to the first electronic device 100 and the second electronic device 200 are within a certain distance range, the first electronic device 100 and the second electronic device 200 may perform bluetooth connection. In an embodiment of the present application, the TWS bluetooth headset apparatus may include a headset 220 and a headset case (charging apparatus) 210, and the headset case 210 may accommodate the headset 220, in an embodiment of the present application, an inner wall of the case of the headset case 210 forms an accommodating cavity, and the headset 220 may be accommodated in the accommodating cavity of the headset case 210. In addition, the earphone box 210 may not only provide an accommodating cavity for accommodating the earphone 220, but also communicate with the earphone 220, so as to obtain information such as an electric quantity, a name, or a network parameter of the earphone 220, so that the first electronic device can be successfully paired with the earphone 220 through the earphone box 210 and realize communication connection. In one embodiment, the earphone box 210 is also used to charge the earphone 220. In an embodiment of the application, when the earphone box 210 is opened, the earphone 220 may be triggered to transmit a Bluetooth Low Energy (BLE) broadcast, and after receiving the BLE broadcast, the first electronic device 100, for example, a smart phone, may establish a bluetooth connection with the earphone 220 based on the BLE broadcast.

As shown in fig. 3, the first electronic device 100 may be a user terminal (e.g., may be a smart phone), and the second electronic device 200 may be a headset in a true wireless bluetooth headset apparatus. When the user terminal 100 is connected to the headset 200, the user terminal 100 and the headset 200 may perform audio data transmission. For example, the user terminal 100 may transmit voice data of a call counterpart to the headset 200, the headset 200 may transmit voice data of a call counterpart to the user terminal 100, and the like, which are not limited herein.

Referring to fig. 4, fig. 4 is a flowchart illustrating a device connection method according to an embodiment of the present disclosure. The device connection method is used for locally storing the SDP data of the specified configuration file, simplifying the flow in the subsequent connection process based on the specified configuration file and improving the speed of Bluetooth connection. In a specific embodiment, the device connection method is applied to the device connection apparatus 300 shown in fig. 11 and the electronic device (first electronic device) 100 (fig. 12) provided with the device connection apparatus 300. The specific process of this embodiment will be described below by taking an electronic device as an example, and it is understood that the electronic device applied in this embodiment may include a smart phone, a tablet computer, a wearable electronic device, a bluetooth headset, and other devices having a bluetooth connection function. As will be described in detail with respect to the flow shown in fig. 4, the device connection method may specifically include the following steps:

step S110: the method comprises the steps that when a first electronic device initiates a specified connection to a second electronic device, SDP data of a specified configuration file is obtained from the local part of the first electronic device, wherein the specified connection is a device connection based on the specified configuration file.

When two electronic devices establish a bluetooth connection (e.g., the first electronic device and the second electronic device in this embodiment are establishing a bluetooth connection), they acquire the protocol provided by the other device. Only devices using the same protocol can exchange data as if two people had a meaningful conversation using the same language. Where the bluetooth specification establishes commands and functions that the electronic device performing the bluetooth connection can exchange using bluetooth technology, as the bluetooth protocol defines the physical wireless connection between the two electronic devices.

In some embodiments, the first electronic device and the second electronic device may establish a profile-based connection when performing a bluetooth connection. The Profile may include (cell phone specification, Head-Set-Profile, HSP), Hands-Free specification (hand-Free-Profile, HFP), Advanced Audio Distribution Profile (A2 DP), Audio/Video Remote Control specification (Audio/Video Remote Control Profile, AVRCP), and the like, which are not limited herein. Among them, the HSP and HFP bluetooth specifications are those required for typical monaural bluetooth electronic device operation, and A2DP and AVRCP are important for stereo bluetooth electronic devices.

The HSP is a configuration which is commonly used in Bluetooth connection, and provides basic functions required by communication between the smart phone and the Bluetooth headset for current popular support such as use of the Bluetooth headset and the smart phone. After connection and configuration, the bluetooth headset may be used as an audio input and output interface for the remote device.

Among them, HFP adds some extended functions on the basis of HSP, and is often used to allow, for example, a vehicle-mounted hands-free device to control a smartphone. It uses continuous variable slope delta modulation or pulse code log-one or mu-method quantization audio channel modulation. It is described how the gateway device is used for placing and receiving calls for hands-free devices. Typical configurations such as automobiles use a smartphone as the gateway device. In a car, a stereo system is used for telephone audio, while a microphone mounted in the car is used for transmitting output audio during a call. HFP can also be used in the case of personal computers as smartphone speakers in the home or office environment.

Among other things, A2DP allows for the transmission of stereo audio signals (better quality than mono encryption for HSP and HFP). A2DP enables two electronic devices that also support bluetooth sound transmission to be connected to each other and to output music such as CD sound (16bits, 44.1 kHz). If one party does not support A2DP, then the sound effect can only output Handsfree Profile (8bits, 8 kHz).

Among other things, AVRCP is used to send commands (e.g., skip ahead, pause, and play) from a second electronic device (e.g., stereo headphones) to a first electronic device (e.g., a MediaPlayer-equipped computer). AVRCP is designed to provide a standard interface for controlling TV, Hi-Fi devices, etc. This specification is used to permit a single remote control device (or other device) to control all a/V devices that a user may access. It can be used with A2DP or VDP.

In this embodiment, the first electronic device may initiate the designated connection to the second electronic device. The designated connection may be a device connection based on a designated profile, wherein the designated profile may be one or a combination of HSP, HFP, A2DP, and AVRCP. For example, a designated connection may be an HSP-based device connection initiated by a first electronic device to a second electronic device; the designated connection may be, without limitation, a device connection based on A2DP initiated by the first electronic device to the second electronic device, and so on.

After the pairing is completed and before the connection is performed, the first electronic device and the second electronic device both need to perform service search, where a flow of the service search is SDP, that is, the first electronic device needs to execute an SDP flow to obtain SDP data of the second electronic device in the connection. In this embodiment, when initiating the specified connection to the second electronic device, the first electronic device may obtain SDP data of the specified configuration file (hereinafter referred to as profile) from a local location of the first electronic device, so that an SDP procedure is not performed any more, and an obtaining speed of the SDP data is increased.

As a mode, before initiating the specified connection to the second electronic device this time, the first electronic device has already made the specified connection with the second electronic device, and has already obtained the SDP data of the specified profile when making the specified connection before, so the first electronic device may locally store the SDP data of the specified profile obtained when making the specified connection before, so that when making the specified connection subsequently, the SDP data of the specified profile may be directly obtained from the local, and thus, the obtaining speed of the SDP data may be effectively increased.

Step S120: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

In some embodiments, after the first electronic device obtains the SDP data of the specified profile from the local, the first electronic device may perform specified connection with the second electronic device based on the SDP data of the specified profile, so that the speed of specified connection may be increased.

According to the device connection method provided by the embodiment of the application, when the first electronic device initiates the designated connection to the second electronic device, the first electronic device locally acquires the SDP data of the designated configuration file, wherein the designated connection is based on the designated configuration file, and the SDP data of the designated configuration file is in designated connection with the second electronic device, so that the SDP data of the designated configuration file is locally stored, the flow in the subsequent connection process based on the designated configuration file is simplified, and the speed of Bluetooth connection is improved.

Referring to fig. 5, fig. 5 is a flowchart illustrating a device connection method according to an embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 5, where the device connection method may specifically include the following steps:

step S210: the method comprises the steps that when a first electronic device initiates a specified connection to a second electronic device, SDP data of a specified configuration file is obtained from the local part of the first electronic device, wherein the specified connection is a device connection based on the specified configuration file.

Step S220: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For the detailed description of steps S210 to S220, refer to steps S110 to S120, which are not described herein again.

Step S230: and when the SDP data of the specified configuration file is not stored locally in the first electronic equipment, performing service search to the second electronic equipment based on the specified configuration file.

In some embodiments, when initiating a specified connection to a second electronic device, a first electronic device may determine whether SDP data specifying a profile is stored locally on the first electronic device. As one mode, the first electronic device may preset a storage area corresponding to SDP data of a profile, and therefore, when the first electronic device initiates a specified connection to the second electronic device, it may be determined whether the storage area of the first electronic device includes the SDP data of the specified profile, so that the data volume of the query may be reduced.

When the judgment result represents that the first electronic device locally stores the SDP data of the specified profile, the SDP data of the specified profile can be locally acquired, and the first electronic device is in specified connection with the second electronic device based on the SDP data of the specified profile.

When the judgment result indicates that the SDP data of the specified profile is not locally stored in the first electronic device, service search may be performed on the second electronic device based on the specified profile, that is, when the judgment result indicates that the SDP data of the specified profile is not locally stored in the first electronic device, an SDP service discovery procedure may be performed on the second electronic device based on the specified profile.

Step S240: and when the service search is completed, acquiring SDP data of the specified configuration file from the second electronic equipment.

In some embodiments, when the first electronic device completes service search to the second electronic device based on the specified profile, that is, when the first electronic device completes an SDP service discovery procedure to the second electronic device based on the specified profile, the SDP data of the specified profile may be acquired from the second electronic device.

Step S250: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

In some embodiments, after acquiring the SDP data of the specified profile from the second electronic device, the first electronic device may perform specified connection with the second electronic device based on the SDP data of the specified profile, so as to ensure a success rate of specified connection.

Compared with the device connection method shown in fig. 4, in the device connection method provided in an embodiment of the present application, when the SDP data of the specified configuration file is not stored locally in the first electronic device, the SDP data of the specified configuration file is obtained in a service search manner from the second electronic device to perform specified connection with the second electronic device, so as to ensure a success rate of bluetooth connection.

Referring to fig. 6, fig. 6 is a schematic flowchart illustrating a device connection method according to an embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with reference to the flow shown in fig. 6, where the device connection method may specifically include the following steps:

step S310: the method comprises the steps that when a first electronic device initiates a specified connection to a second electronic device, SDP data of a specified configuration file is obtained from the local part of the first electronic device, wherein the specified connection is a device connection based on the specified configuration file.

Step S320: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For the detailed description of steps S310 to S320, please refer to steps S110 to S120, which are not described herein again.

Step S330: and when the SDP data of the specified configuration file is not stored locally in the first electronic equipment, performing service search to the second electronic equipment based on the specified configuration file.

Step S340: and when the service search is completed, acquiring SDP data of the specified configuration file from the second electronic equipment.

Step S350: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For detailed description of steps S330 to S350, please refer to steps S230 to S250, which are not described herein again.

Step S360: storing SDP data of the specified configuration file locally at the first electronic device.

In some embodiments, after the first electronic device acquires the SDP data of the specified profile from the second electronic device, the SDP data of the specified profile may be stored locally in the first electronic device, so that the SDP data of the specified profile may be directly acquired locally when a specified connection is performed subsequently, and thus, the acquisition speed of subsequent SDP data may be effectively increased.

As one way, the first electronic device may not set the storage time limit. Based on this, after the first electronic device stores the profile-specified SDP data locally at the first electronic device, the profile-specified SDP data may be always stored locally at the first electronic device.

Alternatively, the first electronic device may set a storage time limit. Based on this, after the first electronic device stores the profile-specified SDP data locally in the first electronic device, the profile-specified SDP data may be automatically deleted after being stored in the set storage time limit. For example, the first electronic device may set the storage time limit to be half a year, and when the time after the first electronic device stores the SDP data of the specified profile locally in the first electronic device reaches half a year, the SDP data of the specified profile may be automatically deleted locally in the first electronic device.

As still another way, the first electronic device may set a storage time limit. Based on this, after the first electronic device stores the profile-specified SDP data locally in the first electronic device, the profile-specified SDP data may be stored to the set storage time limit, and then the selection information may be output. The selection information is used for the user to select to delete the SDP data of the specified profile or to reserve the SDP data of the specified profile. In some embodiments, if a deletion instruction that a user selects to delete SDP data of a specified profile is received, the SDP data of the specified profile may be deleted locally at the first electronic device in response to the deletion instruction. In some embodiments, if a reservation instruction is received that the user selects to reserve SDP data specifying a profile, the SDP data specifying the profile may be kept stored locally at the first electronic device in response to the reservation instruction. As an implementable manner, if a reservation instruction for reserving SDP data of a specified profile selected by a user is received, an information input box may be displayed, where the information input box is used for the user to input a duration for continuously storing SDP data of the specified profile, and when a target duration input based on the information input box is received, the SDP data of the specified profile may be continuously stored in the local of the first electronic device for the target duration.

Compared with the device connection method shown in fig. 4, in the device connection method provided in an embodiment of the present application, when the SDP data of the specified configuration file is not stored locally in the first electronic device, the SDP data of the specified configuration file is obtained in a service search manner from the second electronic device to perform specified connection with the second electronic device, so as to ensure a success rate of bluetooth connection. In addition, the SDP data of the specified configuration file is acquired and then stored locally, so that the speed of subsequent Bluetooth connection is improved.

Referring to fig. 7, fig. 7 is a flowchart illustrating a device connection method according to an embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 7, where the device connection method may specifically include the following steps:

step S410: the method comprises the steps that when a first electronic device initiates a specified connection to a second electronic device, SDP data of a specified configuration file is obtained from the local part of the first electronic device, wherein the specified connection is a device connection based on the specified configuration file.

Step S420: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For the detailed description of steps S410 to S420, refer to steps S110 to S120, which are not described herein again.

Step S430: and when the SDP data of the specified configuration file is not stored locally in the first electronic equipment, performing service search to the second electronic equipment based on the specified configuration file.

Step S440: and when the service search is completed, acquiring SDP data of the specified configuration file from the second electronic equipment.

Step S450: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For detailed description of steps S430 to S450, please refer to steps S230 to S250, which are not described herein again.

Step S460: and extracting key data from SDP data of the specified configuration file, wherein the key data is used for carrying out the specified connection with the second electronic equipment.

In some embodiments, after the first electronic device obtains the profile-specified SDP data from the second electronic device, the first electronic device may extract key data from the profile-specified SDP data. Wherein the key data is used for making a designated connection with the second electronic device. As one mode, after acquiring the SDP data of the specified profile from the second electronic device, the first electronic device may acquire key data defined by a profile protocol of the specified profile, and extract the key data from the SDP data of the specified profile according to the key data defined by the profile protocol.

For example, when all the SDP data in the profile-specified SDP data are key data, all the data in the profile-specified SDP data may be directly extracted. For another example, when part of the SDP data in the profile-designated SDP data is key data, part of the SDP data (key data) in the profile-designated SDP data may be extracted.

Step S470: storing the critical data locally to the first electronic device.

In some embodiments, after extracting the critical data from the profile-specific SDP data, the critical data may be stored locally at the first electronic device, while non-critical data in the profile-specific SDP data may not be stored. Based on this, not only can guarantee follow-up bluetooth connection's speed and success rate. The storage volume pressure may also be reduced.

Compared with the device connection method shown in fig. 4, in the device connection method provided in an embodiment of the present application, when the SDP data of the specified configuration file is not stored locally in the first electronic device, the SDP data of the specified configuration file is obtained in a service search manner from the second electronic device to perform specified connection with the second electronic device, so as to ensure a success rate of bluetooth connection. In addition, key data are stored locally after SDP data of a specified configuration file is acquired, so that the speed of subsequent Bluetooth connection is increased and the storage pressure is reduced.

Referring to fig. 8, fig. 8 is a flowchart illustrating a device connection method according to an embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 8, where the device connection method may specifically include the following steps:

step S510: the method comprises the steps that when a first electronic device initiates a specified connection to a second electronic device, SDP data of a specified configuration file is obtained from the local part of the first electronic device, wherein the specified connection is a device connection based on the specified configuration file.

Step S520: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For the detailed description of steps S510 to S520, refer to steps S110 to S120, which are not described herein again.

Step S530: and when the SDP data of the specified configuration file is not stored locally in the first electronic equipment, performing service search to the second electronic equipment based on the specified configuration file.

Step S540: and when the service search is completed, acquiring SDP data of the specified configuration file from the second electronic equipment.

Step S550: and performing the specified connection with the second electronic equipment based on the SDP data of the specified configuration file.

For detailed description of steps S530 to S540, please refer to steps S230 to S250, which are not described herein again.

Step S560: and acquiring the change condition of the SDP data of the specified configuration file based on the configuration protocol in the specified configuration file.

In some embodiments, after the first electronic device acquires the SDP data of the specified profile from the second electronic device, the first electronic device may acquire a change condition of the SDP data of the specified profile based on a configuration protocol in the specified profile. As one mode, after acquiring the SDP data of the specified profile from the second electronic device, the first electronic device may acquire the profile protocol of the specified profile, where the profile protocol defines whether the SDP data of the specified profile is fixed or dynamically changed, that is, defines a change condition of the SDP data of the specified profile, and therefore, after acquiring the profile protocol of the specified profile, the change condition of the SDP data of the specified profile may be acquired based on the profile protocol.

Step S570: and when the change condition represents that the SDP data of the specified configuration file is fixed data, storing the SDP data of the specified configuration file in the local of the first electronic equipment.

In this embodiment, when it is determined that the change condition of the SDP data of the specified profile indicates that the SDP data of the specified profile is fixed data, it may be determined that the SDP data of the specified profile does not change in the subsequent specified connection process between the first electronic device and the second electronic device, that is, the first electronic device may also be based on the SDP data of the specified profile when the subsequent specified connection process between the first electronic device and the second electronic device is performed. Therefore, the SDP data of the specified profile can be stored locally in the first electronic device, so that the SDP data of the specified profile can be directly acquired locally when a specified connection is performed subsequently, and the acquisition speed of the subsequent SDP data can be effectively increased.

Step S580: and when the change condition represents that the SDP data of the specified configuration file is dynamic change data, not storing the SDP data of the specified configuration file in the local of the first electronic equipment.

In this embodiment, when it is determined that the change condition of the SDP data of the specified profile indicates that the SDP data of the specified profile is dynamically changed data, it may be determined that the SDP data of the specified profile is dynamically changed in the subsequent specified connection process between the first electronic device and the second electronic device, that is, the first electronic device cannot be based on the SDP data of the specified profile any more when the first electronic device is in the subsequent specified connection with the second electronic device. Therefore, the profile-specified SDP data may not be stored locally at the first electronic device to reduce the storage pressure of the first electronic device.

Compared with the device connection method shown in fig. 4, in the device connection method provided in an embodiment of the present application, when the SDP data of the specified configuration file is not stored locally in the first electronic device, the SDP data of the specified configuration file is obtained in a service search manner from the second electronic device to perform specified connection with the second electronic device, so as to ensure a success rate of bluetooth connection. In addition, when the SDP data of the specified configuration file is fixed data, the SDP data of the specified configuration file is stored locally so as to improve the success rate of Bluetooth connection.

Referring to fig. 9, fig. 9 is a schematic flowchart illustrating a device connection method according to an embodiment of the present disclosure. The method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 9, where the device connection method may specifically include the following steps:

For detailed description of steps S630 to S650, refer to steps S230 to S250, which are not described herein again.

Step S660: and when the second electronic equipment meets the preset equipment condition, storing the SDP data of the specified configuration file in the local of the first electronic equipment.

In some embodiments, the first electronic device may preset and store a preset device condition, where the preset device condition is used as a criterion of the second electronic device. Therefore, in this embodiment, after the SDP data of the specified profile is acquired from the second electronic device, the second electronic device may be compared with the preset device condition to determine whether the second electronic device meets the preset device condition.

When the judgment result indicates that the second electronic device meets the preset device condition, the second electronic device can be considered to meet the condition that the SDP data of the specified profile of the second electronic device is stored in the local of the first electronic device. Thus, SDP data specifying a profile may be stored locally at the first electronic device.

As one way, the preset device condition may include that a connection frequency with the first electronic device is greater than a preset connection frequency. In some embodiments, after the first electronic device acquires the SDP data specifying the profile from the second electronic device, the connection frequency between the first electronic device and the second electronic device may be acquired, and the acquired connection frequency between the first electronic device and the second electronic device is compared with a preset connection frequency to determine whether the connection frequency is greater than the preset connection frequency. When the connection frequency is determined to be greater than the preset connection frequency, it may be determined that the second electronic device is a commonly-used electronic device, and SDP data of the specified profile may be stored locally in the first electronic device, so as to increase the specified connection speed of the first electronic device and the second electronic device. When the connection frequency is determined to be not greater than the preset connection frequency, it may be determined that the second electronic device is an unusual electronic device, and SDP data specifying a profile may not be stored locally in the first electronic device, so as to reduce storage pressure of the first electronic device. The connection frequency may be a connection frequency of the first electronic device and the second electronic device within a preset time period. The preset time period may be in months, weeks, years, etc.

As one way, the preset device condition may include that the number of connections with the first electronic device is greater than a preset number of connections. In some embodiments, after the first electronic device acquires the SDP data specifying the profile from the second electronic device, the connection times of the first electronic device and the second electronic device may be acquired, and the acquired connection times of the first electronic device and the second electronic device are compared with the preset connection times to determine whether the connection times are greater than the preset connection times. When the connection times are determined to be greater than the preset connection times, it can be determined that the second electronic device is a commonly-used electronic device, and SDP data of the specified profile can be stored locally in the first electronic device, so that the specified connection speed of the first electronic device and the second electronic device is increased. When the connection times are determined not to be larger than the preset connection times, the second electronic device can be determined to be an unusual electronic device, and the SDP data of the specified profile may not be stored locally in the first electronic device, so as to reduce the storage pressure of the first electronic device. The connection frequency may be the connection frequency of the first electronic device and the second electronic device within a preset time period. The preset time period may be in months, weeks, years, etc.

As one way, the preset device condition may include an electronic device to which the first electronic device is first connected. In some embodiments, after the first electronic device obtains the SDP data specifying the profile from the second electronic device, it may be determined whether the second electronic device is the electronic device to which the first electronic device is connected for the first time. When it is determined that the second electronic device is the electronic device to which the first electronic device is connected for the first time, the first electronic device and the second electronic device can be considered to have a higher probability of belonging to the same user, and SDP data specifying profile can be stored locally in the first electronic device, so that the specified connection speed of the first electronic device and the second electronic device can be increased. When it is determined that the second electronic device is not the electronic device to which the first electronic device is first connected, it may be considered that the first electronic device and the second electronic device have a greater probability of belonging to one user, and SDP data specifying profile may not be stored locally in the first electronic device, so as to reduce the storage pressure of the first electronic device. In some embodiments, the first electronic device may store a bluetooth connection record, and determine whether the second electronic device is the first electronic device connected to the first electronic device based on the bluetooth connection record.

As one way, the preset device condition may include that the logged-in account is consistent with or associated with the logged-in account of the first electronic device. In some embodiments, after the first electronic device acquires SDP data specifying a profile from the second electronic device, an account registered by the first electronic device and an account registered by the second electronic device may be acquired, and whether the account registered by the first electronic device and the account registered by the second electronic device are consistent or associated is determined. When the account number logged in by the first electronic device is determined to be consistent with or associated with the account number logged in by the second electronic device, the first electronic device and the second electronic device can be considered to have a higher probability of belonging to the same user, and SDP data of the specified profile can be stored in the local of the first electronic device, so that the specified connection speed of the first electronic device and the second electronic device is increased. When it is determined that the account registered by the first electronic device is inconsistent and not associated with the account registered by the second electronic device, the first electronic device and the second electronic device may be considered to belong to one user with a higher probability of different, and SDP data specifying profile may not be stored locally in the first electronic device, so as to reduce storage pressure of the first electronic device.

Step S670: and when the second electronic equipment does not meet the preset equipment condition, acquiring the search frequency for performing service search on the second electronic equipment based on the specified configuration file.

In some embodiments, when the determination result indicates that the second electronic device does not satisfy the preset device condition, it may be determined that the second electronic device does not satisfy the condition that the SDP data of the specified profile of the second electronic device is stored in the local of the first electronic device. Thus, the SDP data specifying the profile may not be stored locally at the first electronic device.

In some embodiments, when the determination result indicates that the second electronic device does not satisfy the preset device condition, it may be determined that the second electronic device is suspected to not satisfy a condition that SDP data of a specified profile of the second electronic device is stored in the local of the first electronic device, and then a search frequency of the first electronic device for performing service search on the second electronic device based on the specified profile may be obtained. That is, the frequency at which the first electronic device performs the SDP procedure to the second electronic device based on the specified profile may be obtained as the search frequency.

Step S680: and when the search frequency is greater than the preset search frequency, storing the SDP data of the specified configuration file in the local of the first electronic equipment.

In some embodiments, the first electronic device may preset and store a preset search frequency, where the preset search frequency is used as a criterion for the first electronic device to perform a service search to the second electronic device based on the specified profile. Therefore, in this embodiment, after the search frequency is obtained, the search frequency may be compared with a preset search frequency to determine whether the search frequency is greater than the preset search frequency.

When the search frequency is greater than the preset search frequency, the probability that the first electronic device and the second electronic device are connected in an appointed mode is considered to be high, and the SDP data of the appointed profile can be stored in the local of the first electronic device, so that the success rate of the appointed connection of the first electronic device and the second electronic device is improved.

When the search frequency is not greater than the preset search frequency, the probability that the first electronic device and the second electronic device are connected in the designated manner is considered to be low, and the SDP data of the designated profile may not be stored locally in the first electronic device, so that the storage pressure of the first electronic device is reduced.

Compared with the device connection method shown in fig. 4, in the device connection method provided in an embodiment of the present application, when the SDP data of the specified configuration file is not stored locally in the first electronic device, the SDP data of the specified configuration file is obtained in a service search manner from the second electronic device to perform specified connection with the second electronic device, so as to ensure a success rate of bluetooth connection. In addition, when the second electronic device meets the preset device condition, or when the second electronic device does not meet the preset device condition and the search frequency of service search to the second electronic device based on the specified configuration file is greater than the preset search frequency, the SDP of the specified configuration file is stored locally, so that the reasonability of the stored SDP is improved.

In this embodiment, the first electronic device locally stores target SDP data of a plurality of configuration files, and the device connection method specifically includes the following steps:

step S710: and when the first electronic equipment initiates a specified connection to the second electronic equipment, determining a configuration file corresponding to the specified configuration file from the plurality of configuration files.

In some embodiments, the target SDP data for each of the plurality of configuration files may be stored locally on the first electronic device. For example, when the plurality of profiles include HSP, HFP, A2DP, and AVRCP, then SDP data of HSP, SDP data of HFP, SDP data of A2DP, and SDP data of AVRCP may be stored locally at the first electronic device.

In this embodiment, when the first electronic device initiates the designated connection to the second electronic device, the profile corresponding to the designated profile may be determined from a plurality of profiles stored locally. For example, assuming that the plurality of profiles include HSP, HFP, A2DP, and AVRCP, if a profile is designated as HSP, HSP corresponding to the designated profile may be determined from among HSP, HFP, A2DP, and AVRCP.

Step S720: and acquiring the SDP data of the configuration file corresponding to the specified configuration file from the local part of the first electronic equipment as the SDP data of the specified configuration file.

In some embodiments, after determining the profile corresponding to the specified profile, the SDP data of the profile corresponding to the specified profile may be acquired from the local of the first electronic device as the SDP data of the specified profile. For example, when it is determined that the profile corresponding to the specified profile is the HSP, the SDP data of the HSP may be acquired from the local of the first electronic device as the SDP data of the specified profile.
