"and/or", describes an association relationship of an association object, and indicates that there may be three relationships, for example, a and/or B, and may indicate: a exists alone, A and B exist together, and B exists alone. The character "/" generally indicates that the context-dependent object is an "or" relationship. The information such as the broadcast data packet, the equipment identifier and the like related to the application can be information authorized by a user or fully authorized by each party.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an implementation environment related to a bluetooth-based device connection method according to an exemplary embodiment of the present application. Referring to fig. 1, the implementation environment includes a plurality of first electronic devices and at least one second electronic device. Taking a first electronic device and a second electronic device as an example, the first electronic device can establish bluetooth connection with the second electronic device within a preset range. The first electronic device is a dual-mode Bluetooth device, and the second electronic device is a dual-mode Bluetooth device or a single-mode Bluetooth device.
The dual-mode Bluetooth device refers to an electronic device comprising Bluetooth modules in different modes. For example, the different modes of bluetooth modules are Basic Rate/enhanced Rate (Basic Rate/ENHANCED DATA RATE, BR/EDR) bluetooth module and bluetooth low energy (Bluetooh Low Energy, BLE) module. The single-mode Bluetooth device refers to an electronic device comprising a Bluetooth module, for example, the Bluetooth module is a BR/EDR Bluetooth module; or the bluetooth module is a BLE module.
The BLE module and the BR/EDR Bluetooth module of the first electronic device can be connected with the Bluetooth module in the second electronic device in a Bluetooth mode, and identity authentication is needed in the Bluetooth connection process of the BLE module and the BR/EDR Bluetooth module with the second electronic device. The BLE module establishes a bluetooth connection with a bluetooth module of the second electronic device by broadcasting the broadcast data packet. Correspondingly, after receiving the broadcast data packet of the BLE module of the first electronic device, the second electronic device initiates Bluetooth connection to the BLE Bluetooth module based on the default authentication mode of the BLE module. And the BR/EDR Bluetooth module establishes Bluetooth connection with the Bluetooth module of the second electronic device by receiving a Bluetooth search request sent by the second electronic device. Correspondingly, the second electronic equipment sends a Bluetooth search request, the first electronic equipment sends a scanning response message to the second electronic equipment after receiving the Bluetooth search request, the second electronic equipment obtains an authentication mode of the BR/EDR Bluetooth module of the first electronic equipment after receiving the scanning response message, and Bluetooth connection is initiated to the BR/EDR Bluetooth module based on the authentication mode.
It should be noted that the second electronic device is an electronic device within a preset range of the first electronic device. The preset range is set according to the range of the bluetooth module broadcast message in the first electronic device and the second electronic device, and in the embodiment of the present application, the preset range is not specifically limited.
The first electronic device and the second electronic device are both electronic devices with Bluetooth modules. For example, each of the first electronic device and the second electronic device may be at least one of a mobile phone, a tablet computer, a PC (Personal Computer, a personal computer), or a wearable device, etc. mounted with a bluetooth module. It should be noted that the first electronic device and the second electronic device are the same type of electronic device or different types of electronic devices. For example, the first electronic device is a bluetooth headset, and the second electronic device is a mobile phone or the like.
Referring to fig. 2, a flowchart of a bluetooth-based device connection method according to an exemplary embodiment of the present application is shown. The execution main body in the embodiment of the application is the first electronic device, and can also be a Bluetooth module of the first electronic device, a processor of the first electronic device, an operating system of the first electronic device, or the like. The method comprises the following steps:
Step S21: the first electronic device generates a first broadcast data packet based on an authentication mode of the first Bluetooth module.
The first Bluetooth module is a BR/EDR Bluetooth module. The first broadcast packet includes a target field indicating an authentication mode of the first bluetooth module.
In this step, the first electronic device determines an authentication method of the first bluetooth module, determines the target field based on the first authentication method, and adds the target field to the second broadcast packet to obtain the first broadcast packet. Referring to fig. 3, the process is implemented by the following steps S21-1 to S21-2, including:
Step S21-1: the first electronic device determines a target field based on the authentication mode, the target field representing the authentication mode of the first bluetooth module.
The authentication mode of the first Bluetooth module is used for carrying out identity authentication on the second electronic equipment based on the authentication mode in the Bluetooth pairing stage, so that whether pairing is successful or not is determined, and Bluetooth connection is established when pairing is successful. The number and type of authentication methods are set as needed, and for example, the authentication methods include a Secure simple pairing (Secure SIMPLE PAIRING, SSP) authentication method and a personal identification number (Personal Identification Number, PIN) code authentication method.
In this step, the first electronic device determines the value of the target field according to the authentication mode of the first bluetooth module. For example, in the case where the authentication method is a secure simple pairing SSP authentication method, the target field is set to a first value; in the case where the authentication method is a personal identification number PIN authentication method, the target field is set to a second value.
The first value and the second value are different, and the first value and the second value are set according to needs, and in the embodiment of the present disclosure, the first value and the second value are not specifically limited. For example, the first value is 1 and the second value is 0.
For example, referring to fig. 4, the first electronic device determines whether the first bluetooth module supports the SSP authentication method, if the first bluetooth module supports the SSP authentication method, the value of the target field is set to a first value, and if the first bluetooth module does not support the SSP authentication method, the value of the target field is set to a second value. And adding the target field with the set value into the second broadcast data packet to obtain a first broadcast data packet so as to be capable of broadcasting the first broadcast data packet.
It should be noted that, the first electronic device determines the target fields corresponding to different authentication modes according to the correspondence between the target fields and the authentication modes. Correspondingly, the first electronic device stores the corresponding relation between the authentication mode and the target field in advance, so that the first electronic device can determine the target field corresponding to the authentication mode of the first Bluetooth module from the corresponding relation between the authentication mode and the target field based on the authentication mode of the first Bluetooth module. For example, in the case that the authentication method is an SSP authentication method, the first electronic device determines that the target field is a first numerical value based on a correspondence between the authentication method and the target field; and under the condition that the authentication mode is a PIN authentication mode, the first electronic device determines that the target field is a second numerical value based on the corresponding relation between the authentication mode and the target field.
In the implementation manner, the authentication mode of the first Bluetooth module is represented by different values of the target field, so that the process of determining the authentication mode of the first Bluetooth module is simplified, and the efficiency of establishing Bluetooth connection is improved.
The second electronic device may store the correspondence between the target field and the authentication mode in advance, or the second electronic device may call the correspondence between the target field stored in the server and the authentication mode from other electronic devices, so that the second electronic device may determine the authentication mode of the first bluetooth module from the correspondence between the target field and the authentication mode according to the target field. For example, in the case that the target field is the first value, the other electronic device determines that the authentication mode is an SSP authentication mode based on the correspondence between the target field and the authentication mode; and under the condition that the target field is the second value, other electronic equipment determines that the authentication mode is a PIN authentication mode based on the corresponding relation between the target field and the authentication mode. The principle of the preset correspondence relation or the setting mode of the correspondence relation called from other electronic devices is the same, and will not be described herein.
Step S21-2: the first electronic device adds the target field to the target field position of the second broadcast data packet to obtain the first broadcast data packet.
In this step, a target field position is determined in the second broadcast data packet, and a target field is added to the target field position to obtain the first broadcast data packet.
In the implementation manner, the target field is added in the second broadcast data packet to obtain the first broadcast data packet capable of indicating the authentication mode of the first Bluetooth module, so that the second electronic device can acquire the authentication mode of the first Bluetooth module through the first broadcast data packet, and further, when the second electronic device establishes Bluetooth connection with the first Bluetooth module of the first electronic device, the process of determining the authentication mode of the first Bluetooth module is not required to be initiated in the Bluetooth pairing process, the step of establishing Bluetooth connection is simplified, and the speed of Bluetooth connection is further improved.
Before this step, the first electronic device determines an authentication mode of the first bluetooth module, and the process includes: the first electronic equipment acquires attribute information of the first Bluetooth module; the first electronic equipment analyzes the attribute information to obtain an authentication mode of the first Bluetooth module.
It should be noted that, the first electronic device executes the step of determining the authentication mode of the first bluetooth module after the bluetooth function is started, caches the authentication mode of the first bluetooth module locally, and deletes the cached authentication mode of the first bluetooth module after the bluetooth function is closed. Or the first electronic equipment obtains the authentication mode of the first Bluetooth module once when leaving the factory, the authentication mode is stored locally, and when the Bluetooth function is started, the authentication mode of the first Bluetooth module is obtained from the local storage. The process of the first electronic device obtaining the authentication mode of the first bluetooth module is the same as the principle of the first electronic device obtaining the authentication mode of the first bluetooth module based on the attribute information, which is not described herein again.
In the implementation mode, the authentication mode of the first Bluetooth module is acquired through the attribute information of the first Bluetooth module, so that the accuracy of the acquired authentication mode of the first Bluetooth module is ensured.
Step S22: the first electronic device broadcasts a first broadcast data packet through the second Bluetooth module, the first Bluetooth module and the second Bluetooth module adopt different Bluetooth modes, and the first broadcast data packet indicates to initiate Bluetooth connection based on an authentication mode.
The second Bluetooth module is a BLE Bluetooth module, wherein the second Bluetooth module periodically broadcasts and broadcasts the first broadcast data packet. The broadcasting period is set as required, and in the embodiment of the present application, the broadcasting period is not particularly limited. For example, the broadcasting period is 1s, 3s, 5s, or the like.
In the implementation manner, the first broadcast data packet is broadcast through the autonomous broadcast function of the BLE Bluetooth module, and the target field representing the authentication mode of the first Bluetooth module is added in the first broadcast data packet, so that the authentication mode of the first Bluetooth module is broadcast to the second electronic equipment, and when the second electronic equipment establishes Bluetooth connection with the first Bluetooth module, the authentication mode of the first Bluetooth module is not required to be acquired again in the pairing process, and the efficiency of establishing Bluetooth connection is improved.
The first broadcast data packet indicates an authentication mode of the first bluetooth module. The second electronic device scans the broadcasted first broadcast data packet, analyzes the scanned first broadcast data packet to obtain a plurality of fields of the first broadcast data packet, determines a target field from the plurality of fields, determines an authentication mode of the first Bluetooth module based on the target field, and sends a pairing request to the first electronic device based on the authentication mode of the first Bluetooth module, wherein the pairing request is used for requesting the first Bluetooth module of the first electronic device to perform Bluetooth pairing.
It should be noted that, in the process of broadcasting the first broadcast data through the second bluetooth module, the first electronic device may broadcast the first broadcast data packet on one channel, or may broadcast the first data packet on a plurality of channels respectively. Therefore, the first data packet is broadcast through a plurality of channels, so that the first electronic equipment can scan the first data packet, and the success rate of Bluetooth connection between the first Bluetooth module and the second electronic equipment is improved.
Step S23: and responding to a Bluetooth connection request sent by the second electronic equipment based on the authentication mode, and establishing Bluetooth connection between the first electronic equipment and the second electronic equipment.
Referring to fig. 5, the second electronic device transmits a bluetooth connection request to the first electronic device based on the first broadcast packet. Correspondingly, in the step, the first electronic equipment receives a Bluetooth connection request sent by the second electronic equipment, performs identity authentication on the first electronic equipment based on the Bluetooth connection request, and establishes Bluetooth connection with the second electronic equipment under the condition that authentication is passed. The process is realized by the following steps S23-1 to S23-2, including:
S23-1: and responding to the Bluetooth connection request sent by the second electronic equipment, and authenticating the second electronic equipment by the first electronic equipment based on the authentication mode.
In response to a bluetooth connection operation with a first bluetooth module of the first electronic device, the second electronic device establishes a bluetooth connection with the first bluetooth module of the first electronic device based on an authentication manner of the first bluetooth module.
The Bluetooth connection operation is based on the operation triggered by the second electronic device and is used for requesting to establish Bluetooth connection with the first Bluetooth module of the first electronic device. In some embodiments, the second electronic device displays device identifiers of the plurality of first electronic devices, and in response to detecting a trigger operation on the device identifiers of the first electronic devices, the second electronic device sends a bluetooth connection request to the first electronic devices. The triggering operation may be a clicking operation of a device identifier of the first electronic device, or the like.
In this step, when the second electronic device establishes bluetooth connection with the first bluetooth module of the first electronic device, the second electronic device invokes a target field in the first broadcast packet, determines an authentication mode of the first bluetooth module through the target field, sends a pairing request to the first electronic device based on the authentication mode, and authenticates the second electronic device based on the authentication mode of the first bluetooth module.
Under the condition that the second electronic device stores the corresponding relation between the first electronic device and the target field, the second electronic device determines the corresponding authentication mode of the first electronic device from the corresponding relation between the device identifier and the authentication mode according to the device identifier of the first electronic device corresponding to the Bluetooth connection operation. The process is as follows: the second electronic equipment determines a target field corresponding to the first electronic equipment from a plurality of stored target fields based on the corresponding relation between the equipment identification and the target field according to the equipment identification of the first electronic equipment.
In the implementation manner, the target field corresponding to the first electronic device is determined based on the corresponding relation between the device identifier and the target field through the device identifier of the first electronic device, so that the authentication mode corresponding to the first Bluetooth module corresponding to the Bluetooth connection can be rapidly and accurately determined under the condition that a plurality of target fields are stored in the second electronic device, and the efficiency of establishing the Bluetooth connection is improved.
S23-2: and the first electronic equipment establishes Bluetooth connection with the second electronic equipment under the condition that the identity authentication of the second electronic equipment is passed.
With continued reference to fig. 5, after the authentication is passed, the first electronic device sends a pairing success notification to the second electronic device, the second electronic device sends a connection request to the first electronic device based on the pairing success notification, the first electronic device receives the connection request, and a bluetooth connection is established with the second electronic device based on the connection request.
In the implementation manner, in the process of establishing the Bluetooth connection with the first Bluetooth module of the first electronic device, the authentication mode of the first Bluetooth module is determined through the target field, so that the Bluetooth connection with the first Bluetooth module can be established based on the authentication at the time, and the efficiency of establishing the Bluetooth connection is improved.
The second electronic device deletes the authentication mode of the first bluetooth module scanned this time from the local after establishing bluetooth connection with the first electronic device, and redetermines the authentication mode of the first bluetooth module when scanning next time. Or the second electronic device reserves the authentication mode corresponding to the first electronic device in the scanning, and the authentication mode of the existing first Bluetooth module is not determined again in the next scanning.
Another point to be described is that, with continued reference to fig. 6, in a process of establishing a bluetooth connection between a second electronic device and a first bluetooth module of a first electronic device for the second electronic device that does not store a target field, the second electronic device sends a device name acquisition request to the first electronic device, and determines an authentication manner of the first bluetooth module of the first electronic device based on the device name acquisition request, where the process is implemented by the following steps (1) - (6), including:
(1) In response to a bluetooth connection operation with the first electronic device, the second electronic device transmits a device name acquisition request to the first electronic device without storing a target field corresponding to the first bluetooth module of the first electronic device.
And after the second electronic device scans the first broadcast data packet, when the first broadcast data packet does not comprise the target field, responding to Bluetooth connection operation with the first electronic device, and sending a device name acquisition request to the first electronic device by the second electronic device.
The device name acquisition request (RNR, remote Name Request) is used to acquire the device name of the first electronic device.
(2) And the first electronic equipment receives the equipment name acquisition request sent by the second electronic equipment.
The device name acquisition request is sent by the electronic device without determining an authentication mode from the first broadcast data packet.
In this step, a temporary bluetooth connection is established between the second electronic device and the first electronic device, the temporary bluetooth connection being used by the second electronic device to obtain the device name of the first electronic device. The first electronic device receives a name acquisition request sent by the first electronic device through the temporary Bluetooth connection.
(3) The first electronic device generates a request response message based on the authentication mode of the first Bluetooth module.
The response message carries device information of the first electronic device, where the device information indicates an authentication mode of the first bluetooth module.
When the first electronic device generates a request response message, feature information (feature) to be exchanged with the second electronic device is added to the request response message, wherein the feature comprises device information of the first electronic device, and the device information is used for indicating an authentication mode of a first Bluetooth module of the first electronic device. For example, the device information includes protocol version information of a bluetooth connection protocol of the first bluetooth module, where different version information corresponds to different authentication modes, and in this step, the first electronic device adds the protocol version of the bluetooth connection protocol used by the first bluetooth module to the request response message.
(4) The first electronic device sends the request response message to the second electronic device.
The first electronic device sends the request reply message to the second electronic device via the temporary bluetooth connection.
(5) The second electronic device receives the request response message sent by the first electronic device.
The second electronic device receives the request response message sent by the first electronic device through the temporary Bluetooth connection.
(6) The second electronic device determines an authentication mode of a first Bluetooth module in the first electronic device from the corresponding relation between the device information and the authentication mode based on the device information of the first electronic device carried in the request response message.
In this step, after receiving the request response message, the second electronic device analyzes the request response message to obtain device information carried in the request response message, and determines an authentication mode of the first bluetooth module in the first electronic device based on a correspondence between the device information and the authentication mode.
For example, the device information includes protocol version information of a bluetooth connection protocol of the first bluetooth module, where different version information corresponds to different authentication modes, and in this step, the second electronic device determines, based on the request response message, a protocol version of the bluetooth connection protocol used by the first bluetooth module, and determines an authentication mode of the first bluetooth module from a correspondence between the protocol version and the authentication mode.
In the implementation manner, under the condition that the second electronic device does not determine the authentication manner of the first Bluetooth module from the first broadcast data packet, the second electronic device obtains the authentication manner of the first Bluetooth module by sending a device name obtaining request to the first electronic device, so that under the condition that the second electronic device does not determine the authentication manner of the first Bluetooth module from the first broadcast data packet, the authentication manner of the first Bluetooth module can also be obtained, thereby ensuring that the second electronic device and the first electronic device establish Bluetooth connection, and improving the success rate of Bluetooth connection.
In the embodiment of the application, the first broadcast data packet added with the target field of the authentication mode of the first Bluetooth module is broadcast through the second Bluetooth module, so that the second electronic device can acquire the authentication mode of the first Bluetooth module through the first broadcast data packet, and the second electronic device does not need to initiate the process of determining the authentication mode of the first Bluetooth module in the process of Bluetooth pairing when establishing Bluetooth connection with the first Bluetooth module of the first electronic device, thereby simplifying the step of establishing Bluetooth connection and further improving the speed of Bluetooth connection.
