As shown in fig. 1, a schematic flowchart of a bluetooth device connection method provided in the present application is applied to a terminal device installed with an application program, and the method includes the following steps:

s101, an application program calls a first system function carrying a page life cycle callback object to determine the current running state of the first system function on terminal equipment;

when the current running state of the application program is determined to be running in the background, the step S102 is carried out;

if the connection status is not connected, go to step S105; if the connection status is connected, go to step S106;

step S105, the application program sends a Bluetooth connection establishment request to the selected Bluetooth equipment, receives a Bluetooth connection establishment response returned by the Bluetooth equipment, and obtains a corresponding establishment result of the Bluetooth connection established with the selected Bluetooth equipment according to the Bluetooth connection establishment response;

step S106, the application program determines that Bluetooth connection is established with the selected Bluetooth equipment;

in step S105 and step S106, after the application program determines that the bluetooth connection has been established with the selected bluetooth device, the process goes to step S101 to continue the process of determining the current operating state of the terminal device.

Based on the above technical solution provided by the present application, the following explains the technical solution in detail, as shown in fig. 2, which is a specific processing flowchart of one possible implementation manner of the bluetooth device connection method provided by the present application.

In one possible implementation, after the user opens the application, the user may perform pre-configuration of the device list in the application; for example, the identification information (which may be unique identification information representing the bluetooth device, such as a mac address) of the required bluetooth device is input into the application program for pre-storing, so that the device list of the application program stores the corresponding information of the input bluetooth device, so that when the subsequent application program scans the bluetooth device in which the identification information is pre-stored, the bluetooth device can be directly connected with the bluetooth device according to the pre-stored identification information.

For the present application, in one possible implementation, the aforementioned processing of step S101 specifically includes the processing of step S201 described below.

In step S201, the application determines its current operating state on the terminal device.

In a possible implementation manner, the application program determines the current running state according to the page state information in the notification message recalled by the terminal device, so as to determine the foreground or the background currently running on the terminal device, and perform corresponding processing according to the current running state running on the foreground or the background. If the device runs in the background, turning to step S202 to query the device list; if the operation is in the foreground, go to step S207.

In one possible implementation, the application may determine from the stored page status information when determining its current running state on the terminal device. When the page of the application program changes, the terminal device performs callback processing on a page life cycle callback object according to a first system function called by the application program, and carries the page state information in a notification message to call back to the application program; the page change may include page display and page hiding;

further, the determining, by the application program, the current running state of the application program on the terminal device by using the first system function carrying the page lifecycle callback object includes:

when the variable value of the state information corresponding to the page state information is determined to be larger than a preset threshold value, determining that the current running state is running in the foreground; and when the variable value of the state information is not larger than the preset threshold value, determining that the current running state is running in the background. In a specific embodiment, for the preset threshold, the value may be 0, that is, when the value of the state information variable is greater than 0, it is determined that the current operating state is operating in the foreground; and when the variable value of the state information is not larger than 0, namely is less than or equal to 0, determining that the current running state is running in the background.

Furthermore, when the page of the display page of the application program changes, the terminal device performs callback processing on the page life cycle callback object according to the first system function called by the application program, and carries the page state information in the notification message to call back to the application program, including:

when the terminal equipment monitors that the page is displayed, the application program receives callback processing of the page callback interface by the terminal equipment, and the application program adds 1 to the variable value of the state information according to the callback processing of the page callback interface;

when the terminal device monitors that the page is hidden, the application program receives callback processing of the page callback interface by the terminal device, and the application program subtracts 1 from the state information variable value according to the callback processing of the page hidden callback interface.

The variable value of the state information stored in the application program is notified to the application program by the terminal device, namely when the display page of the application program is displayed on the terminal device, the terminal device sends a notification message to the application program through the page display callback interface to notify the application program that the display page is currently in a page display state, and the application program adds 1 to the variable value of the state information according to the notification message; once the display page is not displayed on the terminal device, that is, when the display page is page-hidden, the terminal device sends a notification message to the application program through the page-hidden callback interface to tell the application program that the display page is currently in a page-hidden state, and the application program subtracts 1 from the state information variable value.

In one possible implementation, for an application in an open state, a user may perform pre-configuration of a device list in the application; for example, the identification information (which may be unique identification information representing the bluetooth device, such as a mac address) of the bluetooth device is input into an application program to be prestored, so that the device list of the application program stores the input corresponding information of the bluetooth device, and when the subsequent application program scans the bluetooth device prestored with the identification information, the bluetooth device is directly connected with the bluetooth device according to the identification information.

In a specific embodiment, an application program creates a Myapplication class, and configures the name of application in a Manifest.xml application configuration file as Myapplication; the Myapplication class is an application inlet, and the life cycle of a display page can receive a callback in the class; namely, whether the application program is in the foreground or the background is judged through the life cycle of the page. The application program creates a page life cycle callback object in the Myapplication class, and calls a register ActivityLifecycleCallbackks in an onCreate method to register the life cycle callback object, and the change of the page life cycle is displayed to be received in the callback. The page life cycle comprises onactive started and onactive stopped; onactitystarted is a system call by the terminal device when the page comes to the foreground, and onactitystopped is a system call by the terminal device when the page comes to the background.

Wherein, an application program may contain many display pages, and when one display page is displayed in the foreground, the application program is in the foreground; when all the display pages are in the background, the application program is in the background, and a variable activityCount is created in the class to record the number of foreground pages. When the aforementioned onactitystarted is called by the system, activtycount is added with 1, and if activity is equal to 1, the application is switched to the foreground; when onactive stopped is called by the system, activityCount is decremented by 1, and if activity is equal to 0, the application switches to the background.

For the present application, in one possible implementation, the aforementioned processing of step S102 specifically includes the processing of step S202 described below.

In step S202, the application queries the device list.

In one possible implementation, the application queries a pre-configured device list while the application is currently running in the background.

For the present application, in one possible implementation, the aforementioned processing of step S103 specifically includes the processing of step S203 described below.

In step S203, the application program selects a bluetooth device to be processed.

In one possible implementation, the application obtains bluetooth device information for each corresponding bluetooth device by querying the device list. The bluetooth device information may include an identity of the bluetooth device and a current connection status thereof; finding the Bluetooth equipment information of at least 1 Bluetooth equipment in the equipment list by inquiring the equipment list, and selecting 1 Bluetooth equipment from the Bluetooth equipment information of at least 1 Bluetooth equipment for subsequent processing; wherein, if the number of the Bluetooth devices is 1, the Bluetooth device is directly selected; however, if there are at least 2 bluetooth devices, the process of selecting 1 bluetooth device from the at least 2 bluetooth devices may be to arbitrarily select 1 bluetooth device, or may be to select 1 bluetooth device according to a specific sequence, for example, sequentially selecting the bluetooth device ranked first according to the ranking sequence of the at least 2 bluetooth devices in the device list for processing, and of course, the bluetooth device selection process when there are at least 2 bluetooth devices in the device list may be selected in any other manner as long as it is ensured that one of the bluetooth devices is selected for processing.

For the present application, in one possible implementation, the aforementioned processing of step S104 specifically includes the processing of step S204 described below.

In step S204, the application program determines the connection state of the selected bluetooth device.

In one possible implementation, after the application program selects a bluetooth device to be processed from the device list, the connection status of the bluetooth device is obtained according to the connection status information stored in the bluetooth device information of the bluetooth device. If the connection status is not connected, go to step S205; otherwise, go to step S206.

In a possible implementation manner, the connection state information is information obtained by judging the connection state information in a notification message sent by the terminal device received by the application program through a registered connection state callback interface;

when the terminal equipment judges that the terminal equipment is in a connected state with the Bluetooth equipment, the application program receives the connection state information in the notification message through the connection state callback interface as a message of successful connection;

and when the terminal equipment judges that the terminal equipment is in the unconnected state with the Bluetooth equipment, the connection state information in the notification message received by the application program through the connection state callback interface is a message of connection failure.

In a possible implementation manner, the application program calls the terminal device to acquire the bluetooth device object according to the mac address of the bluetooth device in the device list, and then calls the bluetooth device connection interface to register the connection state callback interface through the bluetooth device object, wherein the notification message received in the connection state callback interface includes the bluetooth connection success and the bluetooth connection failure, and the application program can determine the connection state with the bluetooth device according to the notification message; the notification message is sent to the application program through the connection state callback interface after the terminal device judges the connection state with the Bluetooth device.

For the present application, in one possible implementation manner, the processing of the foregoing steps S105 to S106 specifically includes the processing of the following steps S205 to S206.

Step S205, the application program establishes a bluetooth connection with the bluetooth device.

In one possible implementation manner, when the application program determines that the application program is not connected with the bluetooth device, the application program sends a bluetooth connection establishment request to the bluetooth device, and the bluetooth device establishes the bluetooth connection according to the bluetooth connection establishment request sent by the application program; after the bluetooth connection is successfully established, the message that the bluetooth connection is successfully established is carried in the bluetooth connection establishment response and returned to the application program, so that the application program can obtain a corresponding establishment result that the bluetooth connection is established with the selected bluetooth device according to the bluetooth connection establishment response returned by the bluetooth device, and then the process goes to step S201.

In step S206, the application program determines that a connection has been established with the bluetooth device.

In one possible implementation, the application program determines that a corresponding bluetooth connection has been established with the selected bluetooth device when determining that the current connection status is connected, and then goes to step S201.

In one possible implementation, after the above steps S205 and S206, going to step S201, the application program continues to perform the process of determining its current operating state on the terminal device.

In a possible implementation manner, after determining the connection state of the bluetooth device, the application program needs to determine its current running state, so as to determine whether the application program is currently running in the foreground or the background of the terminal device, so as to perform corresponding processing according to the running state currently running in the foreground or the background. If the operation is in the foreground, go to step S207; if the bluetooth device is running in the background, go to step S202, continue to select one bluetooth device from the remaining bluetooth devices in the device list, and determine the connection status of the selected bluetooth device; if the selected Bluetooth device is the last Bluetooth device, other Bluetooth devices which do not establish Bluetooth connection in the device list continue to be subjected to polling processing. Of course, the bluetooth connection processing in the background may be performed all the time when the application runs in the background, or may be preset for a time, and the bluetooth connection processing is stopped as long as the preset time is reached.

In one possible implementation, when the application is currently running in the foreground, the following processing is included:

in step S207, the application performs bluetooth device scanning processing.

In one possible implementation, after determining that the application program is currently running in the foreground, the application program performs a scanning operation of the bluetooth device within a scanning range of the bluetooth device of the terminal device. The scanning range of the bluetooth device may be a scanning range of the default bluetooth device, and may also be adjusted according to the scanning range required by the user, so that only the bluetooth device within the scanning range required by the user is scanned.

In one possible implementation, the application may set a preset time during which the bluetooth device scan is performed when the bluetooth device scan is performed. In the preset time (that is, the preset time is not reached), as long as the bluetooth device is scanned, no matter 1 bluetooth device or a plurality of bluetooth devices, the process goes to step S208, and the application program determines whether the scanned bluetooth device is in a preconfigured device list; when the preset time is reached, the process goes to step S211.

In step S208, the application program obtains the identity information of the scanned bluetooth device.

In one possible implementation, after scanning the bluetooth device, the application program obtains the corresponding identification information, such as the mac address, of the bluetooth device.

In step S209, the application program determines whether the scanned bluetooth device is in a preconfigured device list according to the identification information.

In a possible implementation manner, after acquiring the identification information of the bluetooth device, the application program queries a pre-configured device list according to the acquired identification information, and determines whether the identification information corresponding to each bluetooth device in the device list is matched with the identification information corresponding to the scanned bluetooth device; if the Bluetooth devices are matched, the scanned Bluetooth devices are determined to be in the device list, and the step S210 is carried out; otherwise, it is determined that the scanned bluetooth device is not in the device list, and the process goes to step S207 to continue to execute the bluetooth device scanning process.

Step S210, the application program performs bluetooth connection with the scanned bluetooth device.

In one possible implementation, after determining that the scanned bluetooth device is in the device list, the application program directly performs bluetooth connection with the scanned bluetooth device, and then continues to perform the scanning process of the bluetooth device until the preset time is reached and stops.

In step S211, the application closes the process of scanning the bluetooth device.

In one possible implementation, the application turns off the current scanning bluetooth device processing operations when a preset time is reached. After the application closes the current bluetooth device scanning process, the bluetooth device scanning process is restarted after a certain preset time, and then the process goes to step S207 to continue to execute the bluetooth device scanning process. That is, after the preset time is reached, the application closes the current scanning process no matter whether the application scans the bluetooth device or not, and after the current scanning process is closed, the process of scanning the bluetooth device is started again after the application waits for a specific time, so that the process of scanning the bluetooth device within the preset time is executed again.

In the method, no matter the application program is in the foreground or the background, the automatic Bluetooth connection between the application program and the Bluetooth equipment is realized; when the application program is in the foreground, automatic Bluetooth connection can be realized only by the Bluetooth equipment in the equipment list, manual Bluetooth connection of a user is avoided, and connection efficiency is improved; when the application program runs in the background, the Bluetooth connection aging is guaranteed through continuous background Bluetooth connection processing, the defect that the user cannot realize Bluetooth connection after the application program is switched to the background is avoided, and connection processing of the application program to a plurality of Bluetooth devices in a device list is realized through sequential Bluetooth connection processing, so that the use experience of the user is improved.

Based on the above technical solution of the bluetooth device connection method provided by the present application, the present application correspondingly provides a schematic structural diagram of a bluetooth device connection apparatus, as shown in fig. 3, the bluetooth device connection apparatus 30 of the present application may include:
