[0024] It should be noted that the executor of the method for establishing a Bluetooth connection in this embodiment may be a device for establishing a Bluetooth connection, which may be implemented by software and / or hardware, and which may be configured in an electronic device, which may include but is not limited to a terminal, a server, etc.

[0025] It should be noted that the process of obtaining, storing, using, and processing information in the disclosed technical solution complies with the relevant provisions of national laws and regulations and does not violate public order and good morals.

[0026] Figure 1 is a flow chart of a method for establishing a Bluetooth connection according to the first embodiment of the present disclosure, such as Figure 1 As shown, the method includes:

[0027] S101: Sending a Bluetooth pairing request to a second Bluetooth device to be connected.

[0028] The Bluetooth connection establishment method of the disclosed embodiment is executed by a first Bluetooth device. The first Bluetooth device can be any electronic device with Bluetooth communication function, such as a mobile phone, a tablet computer, or a computer. In order to facilitate the specific description of the Bluetooth connection establishment method of the disclosed embodiment, the disclosed embodiment will take the first Bluetooth device being a mobile phone as an example to specifically explain the disclosed embodiment without limiting this.

[0029] The method for establishing a Bluetooth connection described in the embodiment of the present disclosure can be used to establish a Bluetooth connection between a first Bluetooth device and a second Bluetooth device. The second Bluetooth device can be any electronic device with Bluetooth communication function, such as a Bluetooth headset, a Bluetooth speaker, etc. In order to facilitate the specific description of the method for establishing a Bluetooth connection in the embodiment of the present disclosure, the embodiment of the present disclosure will take the second Bluetooth device being a Bluetooth headset as an example to specifically explain the embodiment of the present disclosure, without limiting this.

[0030] When the first Bluetooth device attempts to perform Bluetooth pairing with the second Bluetooth device, the first Bluetooth device will generate and send a Bluetooth pairing request to the second Bluetooth device.

[0031] S102: Receive extended inquiry response EIR data returned by the second Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device.

[0032] Among them, Extended Inquiry Response (EIR) data refers to the data broadcast by a Bluetooth device when a pairing request is made. When a Bluetooth device is detectable or discoverable by other devices, it will periodically broadcast its EIR data so that other Bluetooth devices can detect it and pair or communicate with it.

[0033] In the disclosed embodiment, after receiving the Bluetooth pairing request sent by the first device, the second Bluetooth device may broadcast its own EIR data to the first device, so that the first Bluetooth device can obtain the EIR data broadcast by the second Bluetooth device.

[0034] Among them, the Service Discovery Protocol (SDP) is a protocol used to discover and describe services between Bluetooth devices. The EIR data includes the Service Discovery Protocol SDP version number supported by the second Bluetooth device. The first SDP version number can be used to identify the SDP version supported by the second Bluetooth device.

[0035] That is to say, in the embodiment of the present disclosure, the first Bluetooth device may receive the EIR data returned by the second device based on the Bluetooth pairing request, and then, may parse the EIR data to obtain the first SDP version number supported by the second Bluetooth device, and then, may trigger the execution of a subsequent Bluetooth connection establishment method based on the first SDP version number. For details, please refer to the subsequent embodiments and will not be repeated here.

[0036] S103: When it is determined that the second Bluetooth device is a preset device, a first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device is obtained from a preset file.

[0037] Among them, the Bluetooth device of a certain device type supported by the first Bluetooth device that is pre-configured in the first Bluetooth device, or the Bluetooth device can be called a preset device. The preset device can be a Bluetooth device that has previously established a Bluetooth connection with the first Bluetooth device, or can be a Bluetooth device that has not previously established a Bluetooth connection with the first Bluetooth device, and there is no restriction on this.

[0038] The file pre-configured in the first Bluetooth device and containing information such as the preset devices supported for connection and the different application specifications (profiles) supported by the first Bluetooth device is the preset file.

[0039] The identifier of the second Bluetooth device may be used to identify a unique Bluetooth device, and the identifier may be, for example, a device serial number, a device name, etc., which is not limited.

[0040] Among them, different Profiles cover Bluetooth protocols and features related to specific functions and specifications, such as phone calls, audio playback, etc. Different Bluetooth devices need to support corresponding profiles to establish a Bluetooth connection. When establishing a Bluetooth connection, Profile matching will be performed between Bluetooth devices to determine whether the Bluetooth devices can communicate and exchange data with each other.

[0041] That is to say, in the embodiment of the present disclosure, the first Bluetooth device can pre-configure a preset file containing a Bluetooth device of a certain device type that it supports connecting, or preset device information of the Bluetooth device, and information such as different application specification profiles, and then, when receiving the extended query response EIR data returned by the second Bluetooth device, the identifier of the second Bluetooth device can be determined. Then, when the preset file contains the identifier of the second Bluetooth device, the second Bluetooth device can be determined to be the preset device, and when it is determined that the second Bluetooth device is the preset device, the first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device can be queried from the preset file.

[0042] In an embodiment of the present disclosure, querying a first application specification profile associated with a first SDP version number and an identifier of a second Bluetooth device from a preset file may be querying a service universally unique identifier (Universally Unique Identifier, UUID) associated with a first SDP version number and an identifier of a second Bluetooth device from a preset file, and the service UUID may be used to identify the corresponding first profile.

[0043] It should be noted that SDP with different version numbers can support different profiles, so the corresponding Profile can be determined according to the SDP version number, thereby ensuring compatibility between Bluetooth devices during connection and communication, and being able to correctly understand and process each other's service functions and characteristics. Accordingly, different Bluetooth devices may have different functions and application scenarios, so the corresponding Profile can be determined according to the Bluetooth device identifier, ensuring that Bluetooth devices can know the functions supported by each other when establishing a Bluetooth connection, and select the appropriate specifications for communication.

[0044] Therefore, in the embodiment of the present disclosure, the profile corresponding to the first SDP version number can be queried from a preset file, and then, the first application specification profile corresponding to the identifier of the second Bluetooth device can be determined from the profile corresponding to the first SDP version number based on the identifier of the second Bluetooth device, thereby ensuring that the first Bluetooth device and the second Bluetooth device can communicate normally and securely and interact according to the expected functions.

[0045] S104: Establishing a Bluetooth connection with a second Bluetooth device based on the first profile.

[0046] In the embodiment of the present disclosure, after the first Bluetooth device obtains the first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device from a preset file, the first Bluetooth device can establish a Bluetooth connection with the second Bluetooth device based on the first profile, so that the first Bluetooth device and the second Bluetooth device can communicate with each other and exchange data based on the commonly supported first profile.

[0047] In the disclosed embodiment, the first Bluetooth device sends a Bluetooth pairing request to the second Bluetooth device to be connected, and receives an extended query response EIR data returned by the second Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device. When it is determined that the second Bluetooth device is a preset device, a first application specification profile associated with the first SDP version number and an identifier of the second Bluetooth device is obtained from a preset file, and a Bluetooth connection is established with the second Bluetooth device based on the first profile, so that information for establishing a Bluetooth connection with the second Bluetooth device can be more conveniently obtained based on the preset file, thereby simplifying the operation of establishing a Bluetooth connection and effectively improving the efficiency of establishing a Bluetooth connection.

[0048] Figure 2 is a flow chart of a method for establishing a Bluetooth connection according to a second embodiment of the present disclosure, such as Figure 2 As shown, the method includes:

[0049] S201: Sending a Bluetooth pairing request to a second Bluetooth device to be connected.

[0050] S202: Receive extended inquiry response EIR data returned by the second Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device.

[0051] The specific description of S201 - S202 can be found in the above embodiment, which will not be repeated here.

[0052] S203: Determine whether the second Bluetooth device supports the SDP-free search function based on the first information in the EIR data.

[0053] The SDP-free search function refers to a function in which the second Bluetooth device can search and obtain service information provided by the Bluetooth device without using SDP when establishing a Bluetooth connection.

[0054] Among them, the first information refers to part of the information in the EIR data used to describe whether the second Bluetooth device supports the SDP-free search function. The first information can be, for example, the device specifications, device manuals, developer documents, etc. of the second Bluetooth device, and there is no limitation on this.

[0055] That is to say, in the embodiment of the present disclosure, after receiving the EIR data returned by the second Bluetooth device, the first Bluetooth device may determine the first information in the EIR data, and determine whether the second Bluetooth device supports the SDP-free search function based on the recorded content in the first information.

[0056] S204: When the second Bluetooth device supports the SDP-free search function, determine whether the identifier of the second Bluetooth device matches any device identifier in the preset list.

[0057] The preset list of the first Bluetooth device may include multiple Bluetooth devices, and the multiple Bluetooth devices in the preset list may be preset Bluetooth devices that support establishing a Bluetooth connection with the first Bluetooth device.

[0058] Each Bluetooth device may have a corresponding unique device identifier, and the device identifier may specifically be, for example, a device serial number, a device name, etc., without limitation.

[0059] That is to say, in the embodiment of the present disclosure, when it is determined that the second Bluetooth device supports the SDP-free search function, the identifier of the second Bluetooth device may be compared with each device identifier in the preset list in turn, and when it is determined that the identifier of the second Bluetooth device is the same as any device identifier in the preset list, it is determined that the identifier of the second Bluetooth device matches the device identifier, and when the identifier of the second Bluetooth device is different from each device identifier, it is determined that the identifier of the second Bluetooth device does not match any device identifier.

[0060] S205: When the identifier of the second Bluetooth device matches any device identifier, determine that the second Bluetooth device is a preset device.

[0061] The embodiment of the present disclosure can determine that the second Bluetooth device is a preset device when it is determined that the identifier of the second Bluetooth device matches any device identifier, so that the first Bluetooth device can accurately determine whether the second Bluetooth device is a preset device based on the matching result between the device identifier of the second Bluetooth device and the device identifier.

[0062] S206: When it is determined that the second Bluetooth device is a preset device, obtain a first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device from a preset file.

[0063] The specific description of S206 can be found in the above embodiment, which will not be repeated here.

[0064] S207: Load the identifier of the second Bluetooth device, the first SDP version number, and the first profile to the specified path.

[0065] Among them, all the information required to establish a Bluetooth connection will be written into a file. Then, the first Bluetooth device can obtain all the information required to establish a Bluetooth connection based on the file. The file can record the information required by multiple Bluetooth devices to establish a Bluetooth connection. In order to facilitate the Bluetooth devices to accurately call their corresponding information, the information required by each Bluetooth device to establish a Bluetooth connection can be stored in the file under a specified path corresponding to the Bluetooth device.

[0066] Therefore, in the embodiment of the present disclosure, the corresponding Bluetooth device may store the identification, first SDP version number and first profile of the second Bluetooth device in a file under a designated path corresponding to the second Bluetooth device after determining the identification, first SDP version number and first profile of the second Bluetooth device. Thus, the first Bluetooth device can conveniently read the information used to establish a Bluetooth connection with the second Bluetooth device.

[0067] S208: Establishing a Bluetooth connection with a second Bluetooth device based on the first profile.

[0068] The specific description of S208 can be found in the above embodiment, which will not be repeated here.

[0069] S209: When the second Bluetooth device does not support the SDP-free search function, or when the identifier of the second Bluetooth device does not match each identifier in the preset list, obtain the second SDP version number and the second profile supported by the second Bluetooth device through the SDP search service.

[0070] In the disclosed embodiment, the identifier of the second Bluetooth device may be compared with each device identifier in a preset list in turn, and when the identifier of the second Bluetooth device is different from each device identifier, it is determined that the identifier of the second Bluetooth device does not match any device identifier.

[0071] That is to say, in the embodiment of the present disclosure, the first Bluetooth device may determine the first information in the EIR data after receiving the EIR data returned by the second Bluetooth device, and determine whether the second Bluetooth device supports the SDP-free search function based on the recorded content in the first information, and when the second Bluetooth device does not support the SDP-free search function, or when the identifier of the second Bluetooth device does not match each identifier in the preset list, obtain the second SDP version number and second profile supported by the second Bluetooth device through the SDP search service.

[0072] Specifically, the first Bluetooth device may enable the Bluetooth SDP search function and perform an SDP search, which causes the first Bluetooth device to send an SDP query request to the second Bluetooth device, so that the second Bluetooth device returns an SDP response, and the first Bluetooth device may extract the required information (the second SDP version number and the second profile) from the SDP response.

[0073] S210: Receive a profile update instruction, where the profile update instruction includes a third profile, a third SDP version number, and a device identifier.

[0074] The profile update instruction may be an instruction sent by the cloud for the first Bluetooth device to update the previously acquired Bluetooth device, and the SDP version number and profile of the Bluetooth device.

[0075] The profile included in the Bluetooth update instruction is the third profile, and the SDP version number is the third SDP version number.

[0076] S211: Based on the device identification and the third SDP version number, traverse the preset files.

[0077] In the disclosed embodiment, after receiving the profile update instruction, the first Bluetooth device may traverse the preset files to see whether the same device identifier and third SDP version number are stored based on the third SDP version number and device identifier in the profile update instruction.

[0078] S212: When the preset file does not include the device identifier and the third SDP version number, the device identifier, the third SDP version number and the third profile are associated and stored in the preset file.

[0079] In the embodiment of the present disclosure, when it is determined that the preset file does not contain the device identification and the third SDP version number, the device identification, the third SDP version number and the third profile can be associated and stored in the preset file, and then the first Bluetooth device can be able to directly read the third SDP version number and the third profile of the Bluetooth device corresponding to the device identification from the preset file, thereby facilitating the first Bluetooth device to quickly establish a Bluetooth connection with the Bluetooth device corresponding to the device identification.

[0080] S213: When the preset file includes the device identifier and the third SDP version number, the fourth profile associated with the device identifier and the third SDP version number in the preset file is replaced with the third profile.

[0081] The profile included in the preset file is the fourth profile, and the fourth profile is the same as or different from the first profile.

[0082] In the embodiment of the present disclosure, when it is determined that the preset file contains the device identification and the third SDP version number, the fourth profile associated with the device identification and the third SDP version number can be determined from the preset file, and then the fourth profile can be updated to the third profile. Thus, the fourth profile associated with the device identification and the third SDP version number in the preset file can be updated in time, so that new functions and features can be introduced. By updating the profile in time, a better user experience and more function options can be obtained when establishing a Bluetooth connection.

[0083] In the embodiment of the present disclosure, the first Bluetooth device sends a Bluetooth pairing request to the second Bluetooth device to be connected, and receives an extended query response EIR data returned by the second Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device, and then determines whether the second Bluetooth device supports the SDP-free search function based on the first information in the EIR data, and if the second Bluetooth device supports the SDP-free search function, determines whether the identifier of the second Bluetooth device matches any device identifier in a preset list, and if the identifier of the second Bluetooth device matches any device identifier, determines that the second Bluetooth device is a preset device, so that the first Bluetooth device can accurately determine whether the second Bluetooth device is a preset device based on the matching result between the device identifier and the device identifier of the second Bluetooth device, and then, if it is determined that the second Bluetooth device is a preset device, obtains a first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device from a preset file, and loads the identifier of the second Bluetooth device, the first SDP version number and the first profile to a specified path, thereby, ... obtains a first application specification profile associated with the first SDP version number and the identifier of the second Bluetooth device from a preset file, and loads the identifier of the second Bluetooth device, the first SDP version number and the first profile to a specified path, thereby, A Bluetooth device can conveniently read information used to establish a Bluetooth connection with a second Bluetooth device, and then establish a Bluetooth connection with the second Bluetooth device based on a first profile, thereby simplifying the operation of establishing a Bluetooth connection and effectively improving the efficiency of establishing a Bluetooth connection, and then receive a profile update instruction, wherein the profile update instruction includes a third profile, a third SDP version number and a device identifier, and based on the device identifier and the third SDP version number, traverse a preset file, and then, if the preset file does not contain the device identifier and the third SDP version number, the device identifier, the third SDP version number and the third profile are associated and stored in the preset file, thereby facilitating the first Bluetooth device to subsequently quickly establish a Bluetooth connection with the Bluetooth device corresponding to the device identifier, and then, if the preset file contains the device identifier and the third SDP version number, the third profile is used to replace the fourth profile associated with the device identifier and the third SDP version number in the preset file. By timely updating the profile, a better user experience and more functional options can be obtained when establishing a Bluetooth connection.

[0084] Figure 3 is a flow chart of a method for establishing a Bluetooth connection according to a third embodiment of the present disclosure, such as Figure 3 As shown, the method includes:

[0085] S301: Receive a Bluetooth pairing request sent by a first Bluetooth device.

[0086] The Bluetooth connection establishment method of the disclosed embodiment is executed by a second Bluetooth device. The second Bluetooth device can be any electronic device with Bluetooth communication function, such as a mobile phone, a tablet computer, or a computer. In order to facilitate the specific description of the Bluetooth connection establishment method of the disclosed embodiment, the disclosed embodiment will take the second Bluetooth device as a Bluetooth headset as an example to specifically explain the disclosed embodiment without limiting this.

[0087] The method for establishing a Bluetooth connection described in the embodiment of the present disclosure can be used to establish a Bluetooth connection between a first Bluetooth device and a second Bluetooth device. The first Bluetooth device can be any electronic device with Bluetooth communication function, such as a Bluetooth headset, a Bluetooth speaker, etc. In order to facilitate the specific description of the method for establishing a Bluetooth connection in the embodiment of the present disclosure, the embodiment of the present disclosure will take the first Bluetooth device as a mobile phone as an example to specifically explain the embodiment of the present disclosure, without limiting this.

[0088] When the first Bluetooth device attempts to perform Bluetooth pairing with the second Bluetooth device, the second Bluetooth device can receive the Bluetooth pairing request sent by the first Bluetooth device.

[0089] S302: Sending extended inquiry response EIR data to the first Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device.

[0090] Among them, Extended Inquiry Response (EIR) data refers to the data broadcast by a Bluetooth device when a pairing request is made. When a Bluetooth device is detectable or discoverable by other devices, it will periodically broadcast its EIR data so that other Bluetooth devices can detect it and pair or communicate with it.

[0091] In the embodiment of the present disclosure, after receiving the Bluetooth pairing request sent by the first device, the second Bluetooth device can broadcast its own EIR data to send the extended query response EIR data to the first Bluetooth device.

[0092] Among them, the Service Discovery Protocol (SDP) is a protocol used to discover and describe services between Bluetooth devices. The EIR data includes the Service Discovery Protocol SDP version number supported by the second Bluetooth device. The first SDP version number can be used to identify the SDP version supported by the second Bluetooth device.

[0093] S303: When the SDP search request sent by the first Bluetooth device is not received, a Bluetooth connection is established with the first Bluetooth device based on the first application specification profile associated with the first SDP version number.

[0094] The SDP search request is made by the first Bluetooth device and is a request for using the SDP to search for and obtain service information provided by the second Bluetooth device.

[0095] Among them, different Profiles cover Bluetooth protocols and features related to specific functions and specifications, such as phone calls, audio playback, etc. Different Bluetooth devices need to support corresponding profiles to establish a Bluetooth connection. When establishing a Bluetooth connection, Profile matching will be performed between Bluetooth devices to determine whether the Bluetooth devices can communicate and exchange data with each other.

[0096] The Profile supported by the second Bluetooth device is the first profile.

[0097] In the embodiment of the present disclosure, when the second Bluetooth device does not receive the SDP search request sent by the first Bluetooth device, it means that the first Bluetooth device can directly obtain the first application specification profile associated with the first SDP version number based on its preset file, so that the second Bluetooth device does not need to perform SDP interaction with the first Bluetooth device, that is, it can directly establish a Bluetooth connection with the first Bluetooth device based on the first application specification profile associated with the first SDP version number.

[0098] In the disclosed embodiment, the second Bluetooth device receives a Bluetooth pairing request sent by the first Bluetooth device, and then sends an extended query response EIR data to the first Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device, and establishes a Bluetooth connection with the first Bluetooth device based on the first application specification profile associated with the first SDP version number without receiving an SDP search request sent by the first Bluetooth device. Thus, a Bluetooth connection can be established with the first Bluetooth device without responding to the SDP search request, thereby simplifying the operation of establishing the Bluetooth connection and effectively improving the efficiency of establishing the Bluetooth connection.

[0108] The profile included in the Bluetooth update instruction is the second profile, and the SDP version number is the second SDP version number.

[0109] S406: Use the second profile and the second SDP version number to replace the first profile and the first SDP version number.

[0110] In the embodiment of the present disclosure, after receiving the profile update instruction, the second Bluetooth device can replace the first profile and the first SDP version number based on the second profile and the second SDP version number in the profile update instruction. By timely updating the profile, a better user experience and more functional options can be obtained when establishing a Bluetooth connection.

[0111] In the disclosed embodiment of the present invention, the second Bluetooth device receives a Bluetooth pairing request sent by the first Bluetooth device, and then sends an extended query response EIR data to the first Bluetooth device, wherein the EIR data includes a first service discovery protocol SDP version number supported by the second Bluetooth device, and establishes a Bluetooth connection with the first Bluetooth device based on a first application specification profile associated with the first SDP version number without receiving an SDP search request sent by the first Bluetooth device.
