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 first electronic device 10 and at least one second electronic device 20 at a home terminal. Wherein, bluetooth modules are installed in the first electronic device 10 and the second electronic device 20. The first electronic device 10 is capable of establishing a bluetooth connection with a second electronic device 20 within a preset range.
The first electronic device 10 broadcasts a bluetooth search request to the network environment via the bluetooth module. After receiving the bluetooth search request, the second electronic device 20 in the network environment responds to the first electronic device 10 based on the bluetooth search request, that is, the second electronic device 20 generates a scan response message and sends the scan response message to the first electronic device 10, and the first electronic device 10 receives the scan response message and establishes a bluetooth connection with the second electronic device 20 that transmits the scan response message based on the scan response message.

The first electronic device 10 and the second electronic device 20 are both devices having bluetooth modules. For example, the first electronic device 10 and the second electronic device 20 may each be a cell phone, a tablet, a wearable device, or the like. It should be noted that the first electronic device 10 and the second electronic device 20 are the same type of electronic device or different types of electronic devices. For example, the first electronic device 10 is a mobile phone, and the second electronic device 20 is a bluetooth headset.
Referring to fig. 2, a flowchart illustrating a bluetooth-based device connection method according to an exemplary embodiment of the present application is shown. The execution subject in the embodiment of the present application is the first electronic device, and may also be a bluetooth module of the first electronic device, a processor of the first electronic device, or an operating system of the first electronic device. For the steps executed by the second electronic device, the execution subject is the second electronic device, a bluetooth module of the second electronic device, a processor of the second electronic device, or an operating system of the second electronic device. The present embodiment takes the first electronic device and the second electronic device as the execution main body as an example for explanation. The method comprises the following steps:
step S21: the first electronic equipment performs equipment scanning in a network environment and acquires a scanning response message of the scanned second electronic equipment.
The first electronic device initiates a second electronic device discovery procedure, based on which a second electronic device capable of establishing a bluetooth connection is determined. The first electronic equipment broadcasts a Bluetooth search request to a network environment; a scan reply message based on the bluetooth search request in the network environment is received. The first electronic equipment broadcasts a Bluetooth search request to a network environment; after receiving a bluetooth search request broadcast in a network environment, the second electronic device generates a scanning response message based on a bluetooth connection protocol of the second electronic device, feeds the scanning response message back to the first electronic device, and the first electronic device receives the scanning response message sent by the second electronic device.
The scanning response message is generated by the second electronic device based on a Bluetooth connection protocol used by the second electronic device. The bluetooth connection protocol includes multiple protocol versions, and the protocol versions used by different second electronic devices are the same or different, which is not specifically limited in this embodiment of the application.
Step S22: the first electronic device determines a reply mode used for scanning the reply message.
The response mode comprises an expanded query response and a non-expanded query response.
In this step, the response mode of the scanning response message is determined based on the message content of the scanning response message. As shown in fig. 3, the process is realized by the following steps S22-1 to S22-2, including:
step S22-1: and the first electronic equipment analyzes the scanning response message to obtain the message content of the scanning response message.
Wherein the message content of the scanning response message generated by the second electronic equipment supporting EIR is different from that of the second electronic equipment not supporting EIR.
In this step, the first electronic device parses the received scanning response message to obtain the message content of the scanning response message. After the first electronic device obtains the scanning response message, the information field carried by the scanning response message is determined, the information field is analyzed, and the information content carried by the information field is obtained, so that the information content of the scanning response message is obtained.
The scanning response message received by the first electronic device is a scanning response message fed back by at least one second electronic device in the current network environment. In some embodiments, the first electronic device determines a scan reply message to be parsed from the at least one scan reply message, and parses the scan reply message to be parsed. The first electronic device determines the earliest received scanning response message as the scanning response message to be analyzed based on the receiving time of the scanning response message. Or the first electronic device determines distance information between the second electronic device and the first electronic device, determines a scanning response message fed back by the second electronic device closest to the first electronic device from at least one scanning response message, and determines the scanning response message as a scanning response message to be analyzed.
In some real-time, the first electronic device parses the at least one scan reply message, respectively. And the first electronic equipment analyzes the at least one scanning response message according to a random sequence. Or the first electronic device analyzes the at least one scanning response message in sequence according to the receiving time of the at least one scanning response message. Or the first electronic device analyzes the at least one scanning response message in sequence according to the distance between the at least one second electronic device and the first electronic device. In the embodiment of the present application, the manner and the sequence of parsing the scan reply message are not particularly limited.
Step S22-2: the first electronic equipment determines a response mode used by the scanning response message based on the message content and the reference message content.
And the reference message content comprises message content corresponding to the expanded query result. In some embodiments, the message content corresponding to the expanded query result includes the message content corresponding to the unexpanded query result and the target message content. In some embodiments, the message content corresponding to the expanded query result includes the target message content. The target message content is the message content not included in the non-expanded query result. For example, the expanded query result includes a device name of the electronic device.
In this step, the message content based on the scan response message is compared with the reference message content, and the response mode used by the message response message is determined based on the comparison result. Referring to fig. 4, the process is realized by the following steps (1) - (3), including:
(1) the first electronic device compares the message content of the scan reply message with the reference message content.
In this step, the first electronic device compares the message content of the scan response message with the field corresponding to the reference message content to obtain a comparison result.
(2) And if the message content is matched with the reference message content, the first electronic equipment determines that the response mode is an expanded query response.
Wherein, the matching of the message content and the reference message content means that the fields included in the message content are the same as the fields included in the reference message content. Or, the matching of the message content and the reference message content means that the field corresponding to the message content includes the field corresponding to the reference message content.
In this step, if the message content matches the reference message content, it is determined that the message content includes the extended query result, i.e., the response mode used by the message content is an extended query response.
(3) And if the message content is not matched with the reference message content, the first electronic equipment determines that the response mode is the non-expanded query response.
In this step, if the message content does not match the reference message, it is determined that the message content does not include the extended query result, i.e., the message content and the used response mode are non-extended query responses.
Step S23: the first electronic equipment determines the version information of the Bluetooth connection protocol used by the electronic equipment based on the response mode, and stores the version information.
Wherein, the bluetooth connection protocol of different editions corresponds the scanning answer message of different answer modes.
In the embodiment of the present application, the protocol versions of the bluetooth connection protocol are divided into a version before the bluetooth connection protocol 2.0 and a version after the bluetooth connection protocol 2.0. Wherein, the version before the bluetooth connection protocol 2.0 does not support Extended Inquiry Results (EIR), that is, the scan response message corresponding to the version before the bluetooth connection protocol 2.0 is a non-Extended Inquiry response; the version after the bluetooth connection protocol 2.0 supports EIR, that is, the scanning response message corresponding to the version after the bluetooth connection protocol 2.0 is an extended inquiry response.
In this step, if the response mode is an extended query response, the first electronic device determines that the version information is the first version information.
In some embodiments, if the response mode is the non-extended query response, the first electronic device determines that the version information is the second version information.
In some embodiments, referring to fig. 5, if the response mode is a non-extended query response, the first electronic device further confirms the version information. Referring to FIG. 6, the process is implemented by the following steps S23-1 to S23-4, including:
step S23-1: and if the response mode is a non-extended query response, the first electronic equipment sends an equipment name acquisition request to the second electronic equipment.
The device name obtaining request is an RNR, and the device name obtaining request is used for obtaining a device name of the second electronic device. In this step, a temporary bluetooth connection is established between the first electronic device and the second electronic device, where the temporary bluetooth connection is used for the first electronic device to obtain the device name of the second electronic device. The first electronic device sends a name acquisition request to the second electronic device through the temporary bluetooth connection.
Step S23-2: the first electronic equipment receives a request response message sent by the second electronic equipment.
In the RNR procedure, the second electronic device using the bluetooth connection protocol corresponding to the second version information does not exchange feature information (feature) with the first electronic device, and the second electronic device using the bluetooth connection protocol corresponding to the first version information exchanges function information with the home device. Therefore, the version information of the bluetooth connection protocol used by the second electronic device can be determined based on whether the request response message carries the feature information of the second electronic device.
In this step, the second electronic device transmits the generated request response message to the first electronic device based on the temporary bluetooth connection.
Step S23-3: if the request response message includes the feature information of the electronic device, the first electronic device determines that the version information is the first version information.
If the request response message includes the feature information of the second electronic device, it is determined that the second electronic device can exchange the feature information in the RNR process, and it is determined that the protocol used by the second electronic device is the bluetooth connection protocol corresponding to the first version information. For example, if there is a "remote host supported features notification event" in the request response message, the first electronic device determines that the version information is the first version information.
Step S23-4: and if the request response message does not comprise the characteristic information of the electronic equipment, the first electronic equipment determines that the version information is the second version information.
If the request response message does not include the feature information of the second electronic device, the second electronic device is determined not to exchange the feature information in the RNR process, and the first electronic device determines that the version information is the second version information.
In this implementation manner, if the content of the scanning response message fed back by the second electronic device is not matched with the content of the reference message, the second electronic device reconfirms the version information of the bluetooth connection protocol used by the second electronic device through the request response message of the device name acquisition request of the second electronic device, thereby ensuring the accuracy of the acquired version information of the bluetooth connection protocol.
Step S24: in response to a bluetooth connection operation with the electronic device, the first electronic device establishes a bluetooth connection with the electronic device based on the stored version information.
When the first electronic device and the second electronic device establish Bluetooth connection, the first electronic device calls a Bluetooth connection protocol of the second electronic device, matches the first electronic device with the second electronic device based on version information of the Bluetooth connection protocol, and establishes Bluetooth connection with the second electronic device if matching is successful. Referring to fig. 7, the process is implemented by the following steps S24-1 to S24-2, including:
step S24-1: and the first electronic equipment determines the authentication mode of the Bluetooth connection protocol corresponding to the version information.
The bluetooth connection protocol corresponding to the first version information adopts a Secure Simple Pairing (SSP) authentication mode, and the bluetooth connection protocol corresponding to the second version information adopts a Personal Identification Number (PIN) code authentication mode.
In this step, the first electronic device determines, based on the version information, bluetooth connection information corresponding to the version information, and further determines an authentication method corresponding to the bluetooth connection protocol.
Before the step, the first electronic device locally stores the acquired version information of the second electronic device. Accordingly, in this step, the first electronic device determines the version information of the second electronic device based on the corresponding relationship between the second electronic device and the version information.
The process of the first electronic device for storing the corresponding relation between the version information and the second electronic device is as follows: the method comprises the steps that a first electronic device obtains a scanned device identifier of at least one second electronic device; and storing the corresponding relation between the equipment identification and the version information of each second electronic equipment.
For each second electronic device, the process of the first electronic device determining the version information corresponding to the second electronic device is similar to the above steps S21-S23, and is not repeated here.
Accordingly, in this step, the first electronic device determines version information corresponding to the second electronic device from the stored version information based on the correspondence relationship. The process is as follows: the method comprises the steps that a first electronic device determines a device identification of a second electronic device to be connected through Bluetooth; based on the device identifier of the second electronic device, determining version information corresponding to the device identifier from the corresponding relation between the device identifier and the version information; and establishing Bluetooth connection with the second electronic equipment based on the Bluetooth connection protocol corresponding to the version information.
The first electronic equipment stores the scanned version information of the second electronic equipment locally in the process of scanning the electronic equipment, and the version information of the second electronic equipment is called locally when connection is established with the second electronic equipment. Correspondingly, before the step, the first electronic device stores the bluetooth version used by the second electronic device locally, and correspondingly, the first electronic device stores the corresponding relationship between the second electronic device and the version information.
The first electronic device correspondingly stores the scanned version information of at least one second electronic device and the second electronic device in the process of scanning the electronic devices. The first electronic device displays the scanned device name of at least one second electronic device, responds to the received trigger operation of the target device name, and calls the stored version information of the second electronic device corresponding to the target device name based on the target device name.
Step S24-2: the first electronic device establishes Bluetooth connection with the electronic device based on the authentication mode.
It should be noted that, after the first electronic device establishes a bluetooth connection with the second electronic device, the version information corresponding to the second electronic device scanned this time is deleted locally, and the version information of the second electronic device is determined again in the next scanning. Or the local electronic device retains the version information corresponding to the scanned second electronic device, and the version information of the existing second electronic device is not determined again in the next scanning.
In the embodiment of the application, in the process of scanning the second electronic device, the version information of the bluetooth connection protocol used by the second electronic device is determined according to the scanning response message of the second electronic device, so that the process of determining the version information does not need to be initiated again in the process of establishing the bluetooth connection, the situation that the version information cannot be determined in the process of establishing the bluetooth connection due to temporary interception failure is prevented, the failure risk of the bluetooth connection is reduced, and the success rate of the bluetooth connection is improved.
