DETAILED DESCRIPTION

[0029] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0030] It should be clear that the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0032] In the description of the present application, it should be understood that the terms "first", "second", "third", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0033] It should be noted that due to space limitations, this application specification does not list all optional implementation methods. After reading this application specification, those skilled in the art should be able to think that as long as the technical features do not contradict each other, any combination of technical features can constitute an optional implementation method. Each embodiment is described in detail below.

[0034] In the development of mobile terminals, when calling some device functions, for example, when making a Bluetooth connection, it is necessary to call an API (Application Programming Interface) provided by the native layer.

[0035] When making a Bluetooth connection, call the Bluetooth scanning API interface implemented by the native SDK to retrieve the Bluetooth devices that can be connected near the terminal. After obtaining the nearby connectable Bluetooth devices, the Bluetooth devices can be compared one by one according to the expected conditions pre-set by the user. For example, the expected conditions can be the name of the Bluetooth device that is expected to be connected to Bluetooth. Find the Bluetooth device that meets the expected conditions, call the Bluetooth connection API interface implemented by the native SDK, and connect to the Bluetooth device.

[0036] However, when connecting to a Bluetooth device, the API interface is still being called to query the Bluetooth device information and try to connect to the Bluetooth. Multiple calls to the interface will cause transmission delays and long calls to the interface. Multiple connections will occur, that is, multiple Bluetooth connection operations are performed simultaneously within a short period of a few seconds, and multiple connection information is fed back. The user perceives that multiple devices are connected at the same time, affecting the efficiency and accuracy of the Bluetooth connection.

[0037] The present application provides a Bluetooth connection method, device, electronic device and storage medium, aiming to solve the above technical problems in the prior art.

[0038] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0039] Figure 1 1 is a flow chart of a method for Bluetooth connection provided according to an embodiment of the present application. The method is applied to a terminal and can be executed by a Bluetooth connection device. Figure 1 As shown, the method comprises the following steps:

[0040] S101. In response to a Bluetooth device connection operation issued by a user through a visual interface of a terminal, determine a device identifier of a target Bluetooth device to be connected to the terminal; wherein the device identifier is used to represent the Bluetooth device.

[0041] Exemplarily, the terminal may be a terminal device such as a mobile phone or a computer. In this embodiment, the terminal has a Bluetooth connection function. The user may turn on the Bluetooth of the terminal, and the terminal may scan nearby Bluetooth devices and display the scanned nearby Bluetooth devices on a visual interface of the terminal. For example, the terminal may scan Bluetooth devices within a preset radius with the terminal as the center. The Bluetooth devices may be devices such as headphones, mobile phones, and keyboards.

[0042] The user can view nearby Bluetooth devices through the terminal visualization interface, and the user can select one of the Bluetooth devices as the target Bluetooth device and issue a Bluetooth device connection operation to the target Bluetooth device. The target Bluetooth device is the Bluetooth device to be connected with the terminal, that is, the user expects the terminal to connect with the target Bluetooth device. For example, the user can click on the target Bluetooth device to instruct the terminal to connect with the target Bluetooth device, that is, the click operation can be a Bluetooth connection operation, and the clicked Bluetooth device is the target Bluetooth device.

[0043] Each Bluetooth device has a unique device identifier, which can be used to represent the Bluetooth device. For example, the device identifier can be the factory number or device name of the device. After determining the target Bluetooth device selected by the user, the device identifier of the target Bluetooth device is determined. For example, the device number of the target Bluetooth device is "001". The user can also enter the device identifier of the Bluetooth device on the visual interface of the terminal. The Bluetooth device corresponding to the entered device identifier is the target Bluetooth device, and the device identifier of the target Bluetooth device is obtained.

[0044] In this embodiment, in response to a Bluetooth device connection operation issued by a user through a visual interface of a terminal, a device identification of a target Bluetooth device to be connected to the terminal is determined, including: according to a connection operation issued by a user on the visual interface of the terminal to any selected Bluetooth device, any selected Bluetooth device is determined as a target Bluetooth device to be connected to the terminal; and the device identification of the target Bluetooth device is determined.

[0045] Specifically, after turning on Bluetooth, the terminal starts scanning Bluetooth devices, and displays the scanned Bluetooth devices on the visual interface of the terminal. The user can select any Bluetooth device from the scanned Bluetooth devices as the target Bluetooth device, and instruct the terminal to connect to the target Bluetooth device through Bluetooth. For example, the user can make a connection operation for any Bluetooth device in the visual interface, and the connection operation can be a click operation of the user, that is, the user can click the target Bluetooth device on the interface. The Bluetooth device clicked by the user is the target Bluetooth device selected by the user.

[0046] After determining the target Bluetooth device, obtain the device identification of the target Bluetooth device, for example, the device name of the target Bluetooth device on the visual interface can be used as the device identification. In this embodiment, after scanning a Bluetooth device near the terminal, the terminal can pause scanning of nearby Bluetooth devices or continue scanning nearby Bluetooth devices.

[0047] The beneficial effect of such a setting is that the user can select the target Bluetooth device according to actual needs, thereby improving the flexibility of the Bluetooth connection.

[0048] S102: Based on the Bluetooth scanning function of the terminal, an unconnected Bluetooth device is discovered within a preset range of the terminal.

[0049] Exemplarily, after determining the device identification of the target Bluetooth device, the terminal can turn on the Bluetooth scanning function. If the terminal has always turned on the Bluetooth scanning function, the Bluetooth scanning can continue. Determine whether there is an unconnected Bluetooth device within a preset range. The preset range can be a range within a preset radius centered on the terminal. The scanned Bluetooth device can be the same as or different from the Bluetooth device displayed on the visual interface. For example, if the terminal is a computer, it can scan nearby unconnected Bluetooth devices such as headphones, keyboards, and mice.

[0050] If an unconnected Bluetooth device is found within the preset range of the terminal, S103 can be executed, that is, it is not necessary to discover all Bluetooth devices within the preset range of the terminal before executing S103, so as to avoid the terminal from performing long-term scanning and improve the efficiency of Bluetooth connection. S103 can also be executed after a preset number of unconnected Bluetooth devices are found. For example, S103 is executed after three Bluetooth devices are found, so as to avoid the terminal from performing frequent scanning in the future, reduce the number of scans, and improve the efficiency of Bluetooth connection.

[0051] S103. If it is determined that the preset first flag bit is the preset initial value, the device identification of the unconnected Bluetooth device is determined, and the first flag bit is updated from the initial value to the preset target value; wherein the first flag bit is used to indicate the judgment state of the terminal for judging the two device identifications, the judgment state includes no judgment and judgment, the initial value of the first flag bit indicates that the judgment state of the terminal for judging the two device identifications is in a state of no judgment, and the target value of the first flag bit indicates that the judgment state of the terminal for judging the two device identifications is in a state of judgment.

[0052] Exemplarily, a first flag is pre-set, and the first flag is used to indicate the judgment state of the terminal for judging the two device identifiers. The terminal judging the two device identifiers means that the terminal compares and judges the device identifier of the target Bluetooth device with the device identifier of the scanned Bluetooth device. The judgment state includes a state where no judgment is made and a state where judgment is made. The first flag can be preset with two values, including an initial value and a target value. The initial value of the first flag indicates that the judgment state of the terminal for judging the two device identifiers is in a state where no judgment is made, and the target value of the first flag indicates that the judgment state of the terminal for judging the two device identifiers is in a state where judgment is made. For example, the initial value is 0, and the target value is 1. If the first flag is 0, it means that the terminal has not compared the device identifiers; if the first flag is 1, it means that the terminal is comparing the device identifiers.

[0053] After determining that there is an unconnected Bluetooth device within the preset range of the terminal, determine whether the first flag is an initial value, that is, whether the terminal is currently performing a device identification comparison. If it is an initial value, that is, it is determined that the terminal is not currently performing a device identification comparison, then obtain the device identification of the scanned unconnected Bluetooth device, so as to compare the device identification of the scanned unconnected Bluetooth device with the device identification of the target Bluetooth device. After obtaining the device identification of the unconnected Bluetooth device, the first flag can be updated from the initial value to the target value. For example, change the first flag from 0 to 1.

[0054] If it is determined that the first flag bit is not the initial value but the target value, it means that the terminal is currently determining the device identification and does not compare the device identification of the currently scanned unconnected Bluetooth device with the device identification of the target Bluetooth device, thereby reducing interface calls and avoiding multiple connection information feedback.

[0055] In this embodiment, after an unconnected Bluetooth device is found within a preset range of the terminal based on the Bluetooth scanning function of the terminal, it also includes: if it is determined that the preset first flag bit is a preset target value, the first flag bit is monitored according to a preset monitoring period; if it is determined that the first flag bit is updated from the target value to the initial value, the device identification of the unconnected Bluetooth device is determined, and the first flag bit is updated from the initial value to the preset target value.

[0056] Specifically, if it is determined that the first flag bit is currently the target value, it means that the terminal is currently determining the device identification, and it is necessary to wait until the terminal completes the current determination before making a new determination. Therefore, it is necessary to monitor whether the first flag bit becomes the initial value. The first flag bit can be monitored in real time or periodically, for example, a monitoring cycle is preset, and according to the preset monitoring cycle, the first flag bit is regularly determined to be the target value or the initial value.

[0057] If it is determined that the first flag bit changes from the target value to the initial value, it means that the terminal has completed the previous judgment process. If the previously judged unconnected Bluetooth device is not the target Bluetooth device, the device identification of the currently unconnected Bluetooth device can be determined, and the first flag bit is updated from the initial value to the preset target value. That is, after determining that there is an unconnected Bluetooth device, the device identification is not necessarily judged immediately. The device is judged only when the first flag bit is the initial value, and when the judgment begins, the second flag bit is adjusted to the target value in time to avoid judging other Bluetooth devices.

[0058] The beneficial effect of such a setting is that it avoids calling other interfaces multiple times when calling a connection interface of a Bluetooth device, so that the terminal will not feedback multiple connection information, avoids incorrect feedback information received by the user, improves the accuracy of Bluetooth connection, and enhances user experience.

[0059] S104: If it is determined that the device identification of the target Bluetooth device is consistent with the device identification of the unconnected Bluetooth device, the unconnected Bluetooth device is connected and the Bluetooth scanning function is turned off.

[0060] For example, after obtaining the device identification of the currently scanned unconnected Bluetooth device, the device identification of the target Bluetooth device is compared with the device identification of the unconnected Bluetooth device to determine whether the two are consistent. If they are consistent, it is determined that the currently scanned unconnected Bluetooth device is the target Bluetooth device, and the terminal can connect to the unconnected Bluetooth device with Bluetooth, and turn off the Bluetooth scanning function to avoid the terminal from continuing to scan and repeatedly judging; if they are inconsistent, it is determined that the currently scanned unconnected Bluetooth device is not the target Bluetooth device, and the terminal needs to continue scanning the Bluetooth device and judging the device identification.

[0061] In this embodiment, after determining the device identification of the unconnected Bluetooth device and updating the first flag bit from the initial value to the preset target value, it also includes: if it is determined that the device identification of the target Bluetooth device is inconsistent with the device identification of the unconnected Bluetooth device, the first flag bit is updated from the target value to the preset initial value.

[0062] Specifically, if it is determined that the unconnected Bluetooth device is the target Bluetooth device, the first flag bit can be reset to the initial value after the Bluetooth scanning function is turned off, so as to facilitate the judgment of the device identification when Bluetooth is turned on next time. If it is determined that the unconnected Bluetooth device is not the target Bluetooth device, the first flag bit is updated from the target value to the initial value, and the terminal can obtain the device identification of the newly scanned unconnected Bluetooth device and judge the device identification again.

[0063] If an unconnected Bluetooth device is found when executing S102, S103 is started, and S102 is executed again after determining that the device identifier of the target Bluetooth device is inconsistent with the device identifier of the unconnected Bluetooth device; if multiple unconnected Bluetooth devices are found when executing S102, S103 is executed after determining that the device identifier of the target Bluetooth device is inconsistent with the device identifier of one of the unconnected Bluetooth devices, and S102 is executed again after all the multiple unconnected Bluetooth devices found are judged.

[0064] The beneficial effect of such a setting is that if the target Bluetooth device is not found, the first flag bit is updated in time, which facilitates subsequent judgment of other Bluetooth devices and improves the efficiency of Bluetooth connection.

[0065] A method for Bluetooth connection provided by an embodiment of the present application determines the target Bluetooth device to be connected through user operation, and obtains the device identification of the target Bluetooth device. According to the Bluetooth scanning function of the terminal, it is determined whether there is an unconnected Bluetooth device within the preset range of the terminal. If it exists, it is determined whether the first flag is a preset initial value. If so, the device identification of the unconnected Bluetooth device is determined, the device identification of the target Bluetooth device is compared with the device identification of the unconnected Bluetooth device, and the first flag is updated from the initial value to the preset target value to avoid calling the Bluetooth connection interface again during the comparison process. If it is determined that the device identification of the target Bluetooth device is consistent with the device identification of the unconnected Bluetooth device, the unconnected Bluetooth device is connected, and the Bluetooth scanning function is turned off to avoid the terminal from continuing to scan and making repeated judgments. In the prior art, the SDK interface is called multiple times in the process of connecting a Bluetooth device, resulting in transmission delays, long calling interface duration, and other problems. Avoid multiple connections and feedback of multiple connection information, improve the efficiency and accuracy of Bluetooth connections, and enhance user experience.

[0066] Figure 2 A flowchart of a Bluetooth connection method provided in an embodiment of the present application is provided. This embodiment is an optional embodiment based on the above embodiment.

[0067] In this embodiment, based on the Bluetooth scanning function of the terminal, an unconnected Bluetooth device is found within a preset range of the terminal, which can be further refined as follows: if based on the Bluetooth scanning function of the terminal, at least one unconnected Bluetooth device is found within a preset range of the terminal, the preset second flag bit is updated from a preset first value to a second value; wherein the second flag bit is used to indicate the scanning result of the terminal for the unconnected Bluetooth device; the scanning result includes finding an unconnected Bluetooth device and not finding an unconnected Bluetooth device; the first value indicates that no unconnected Bluetooth device is found, and the second value indicates that an unconnected Bluetooth device is found.

[0068] like Figure 2 As shown, the method comprises the following steps:

[0069] S201. In response to a Bluetooth device connection operation issued by a user through a visual interface of a terminal, determine a device identifier of a target Bluetooth device to be connected to the terminal; wherein the device identifier is used to represent the Bluetooth device.

[0070] Exemplarily, this step may refer to the above-mentioned step S101 and will not be described in detail.

[0071] S202. If at least one unconnected Bluetooth device is found within a preset range of the terminal based on the Bluetooth scanning function of the terminal, the preset second flag bit is updated from the preset first value to the second value; wherein the second flag bit is used to indicate the scanning result of the terminal for the unconnected Bluetooth device; the scanning result includes finding an unconnected Bluetooth device and not finding an unconnected Bluetooth device; the first value indicates that no unconnected Bluetooth device is found, and the second value indicates that an unconnected Bluetooth device is found.

[0072] Exemplarily, a second flag bit may be pre-set, and the second flag bit may be used to indicate the scanning result of the terminal for the unconnected Bluetooth device, and the scanning result may include finding the unconnected Bluetooth device and not finding the unconnected Bluetooth device. The second flag bit may be preset with two values, namely a first value and a second value, the first value may indicate that the unconnected Bluetooth device is not found, and the second value may indicate that the unconnected Bluetooth device is found, for example, the first value is 0 and the second value is 1.

[0073] Before performing a Bluetooth scan, the second flag is preset to the first value. If one or more unconnected Bluetooth devices are found within the preset range of the terminal, the second flag is updated from the preset first value to the second value, indicating that an unconnected Bluetooth device is found nearby. If no unconnected Bluetooth device is found nearby, the second flag is always the first value. After the terminal finds an unconnected Bluetooth device nearby, the second flag can be updated to the second value.

[0074] After the second flag bit changes to the second value, the Bluetooth scanning function can be suspended and S203 can be executed. After the unconnected Bluetooth devices found are determined, if the unconnected Bluetooth devices found are not the target Bluetooth devices, the second flag bit is updated from the second value to the first value, and the Bluetooth scanning is restarted to obtain new unconnected Bluetooth devices. If it is determined that the unconnected Bluetooth device is the target Bluetooth device, the Bluetooth scanning function is turned off. That is, the Bluetooth scanning function can be turned on when the second flag bit is the first value, and the Bluetooth scanning function can be suspended when the second flag bit is the second value. The Bluetooth scanning function can also be turned on until the target Bluetooth device is found.

[0075] After a nearby unconnected Bluetooth device is found, the second flag is updated from the preset first value to the second value, and S203 is executed. When it is determined that the unconnected Bluetooth device is not the target Bluetooth device, the second flag is updated from the second value to the first value, and a nearby unconnected device is obtained again, and S202 is re-executed to realize the cyclic execution of the Bluetooth connection process.

[0076] In this embodiment, the method also includes: if the second flag bit is determined to be a preset first value according to a preset scanning cycle, it is determined that there are no unconnected Bluetooth devices within the preset range of the terminal, and a prompt message is sent to the user; wherein the prompt message is used to indicate that there are no unconnected Bluetooth devices within the preset range of the terminal.

[0077] Specifically, a scanning cycle can be preset, and the second flag bit is monitored according to the preset scanning cycle to determine whether the second flag bit is still the first value. For example, the terminal has not found any unconnected Bluetooth devices nearby, and the second flag bit is always the first value. Alternatively, the terminal finds that there are unconnected Bluetooth devices nearby, but none of them are target Bluetooth devices, and the second flag bit always changes from the first value to the second value and then to the first value. After a period of time, the second flag bit is still the first value.

[0078] If the second flag is determined to be the first value according to the scanning cycle, it can be considered that there is no unconnected Bluetooth device within the preset range of the terminal, and the Bluetooth connection cannot be completed. The terminal can send a prompt message to the user, prompting the user that there is no unconnected Bluetooth device within the preset range of the terminal. The user can change the range of the terminal or change the target Bluetooth device according to the prompt message.

[0079] The beneficial effect of such a setting is that by monitoring the second flag bit, it is possible to determine whether there is an unconnected Bluetooth device, thereby avoiding the terminal from performing Bluetooth scanning all the time, providing timely reminders to the user, and improving the efficiency of Bluetooth connection.

[0080] S203. If it is determined that the preset first flag bit is the preset initial value, the device identification of the unconnected Bluetooth device is determined, and the first flag bit is updated from the initial value to the preset target value; wherein the first flag bit is used to indicate the judgment state of the terminal for judging the two device identifications, the judgment state includes no judgment and judgment, the initial value of the first flag bit indicates that the judgment state of the terminal for judging the two device identifications is in a state of no judgment, and the target value of the first flag bit indicates that the judgment state of the terminal for judging the two device identifications is in a state of judgment.

[0081] Exemplarily, this step may refer to the above-mentioned step S103 and will not be described in detail.

[0082] S204: If it is determined that the device identification of the target Bluetooth device is consistent with the device identification of the unconnected Bluetooth device, the unconnected Bluetooth device is connected and the Bluetooth scanning function is turned off.

[0083] Exemplarily, this step may refer to the above-mentioned step S104 and will not be described in detail.

[0084] A method for Bluetooth connection provided by an embodiment of the present application determines the target Bluetooth device to be connected through user operation, and obtains the device identification of the target Bluetooth device. According to the Bluetooth scanning function of the terminal, it is determined whether there is an unconnected Bluetooth device within the preset range of the terminal. If it exists, it is determined whether the first flag is a preset initial value. If so, the device identification of the unconnected Bluetooth device is determined, the device identification of the target Bluetooth device is compared with the device identification of the unconnected Bluetooth device, and the first flag is updated from the initial value to the preset target value to avoid calling the Bluetooth connection interface again during the comparison process. If it is determined that the device identification of the target Bluetooth device is consistent with the device identification of the unconnected Bluetooth device, the unconnected Bluetooth device is connected, and the Bluetooth scanning function is turned off to avoid the terminal from continuing to scan and making repeated judgments. In the prior art, the SDK interface is called multiple times in the process of connecting a Bluetooth device, resulting in transmission delays, long calling interface duration, and other problems. Avoid multiple connections and feedback of multiple connection information, improve the efficiency and accuracy of Bluetooth connections, and enhance user experience.
