"and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship.

It should be noted that the user information (including but not limited to user device information, user personal information, etc.) referred to in the present application is information authorized by the user or sufficiently authorized by each party.

Fig. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Referring to fig. 1, the implementation environment includes a first device 101 and a second device 102. The first device 101 and the second device 102 are connected via a wireless or wired network. The first device and the second device are any electronic devices, and the first device 101 and the second device 102 illustratively include a notebook computer, a mobile phone, a tablet computer, a sound box, a car machine, a watch, a television, an electric lamp, a treadmill, a refrigerator, and the like.

Wherein, the first device 101 is configured to send back the connection broadcast to request the device meeting the connection-back condition to establish a connection with the first device 101 in case that the connection between the first device 101 and the second device 102 is abnormally disconnected. The reconnection condition is a condition that needs to be satisfied by the device that establishes the reconnection with the first device 101. The method can utilize the loopback condition to limit the devices that are in the loopback connection with the first device 101, but not to establish the loopback connection between the first device 101 and the currently disconnected second device 102, so that the connection between the devices is more flexible.

Illustratively, the first device 101 and the second device 102 have applications installed therein, and the first device 101 and the second device 102 can establish a connection through the applications and transmit data based on the connection. Optionally, the application is an application in an operating system of the first device 101 and the second device 102, or an application provided by a third party. Optionally, the application is any application, for example, a game application, a music application, a video application, and the like, and the embodiment of the present application is not limited thereto.

Optionally, the implementation environment further includes at least one third device 103 (1 is taken as an example in the figure), and the third device 103 is configured to receive the backhaul broadcast sent by the first device 101, determine whether itself meets a backhaul condition, and establish a connection with the first device 101 if the backhaul condition is met. It should be noted that the second device 102 also receives the backhaul broadcast transmitted by the first device 101, and can establish a connection with the first device 101 if it satisfies the backhaul condition.

The method provided by the embodiment of the application can be applied to a screen projection scene. For example, the first device is a television, the second device is a mobile phone, the third device is a tablet personal computer, after the television and the mobile phone are connected, video content in the mobile phone is launched on the television, and due to movement of a user, the mobile phone carried by the user is far away from the television, so that the connection between the television and the mobile phone is abnormally disconnected. After receiving the reconnection broadcast, the tablet computer determines that the tablet computer meets the reconnection condition, and then establishes connection with the television. The user can then drop the video content of the tablet computer onto the television. It should be noted that, in the case where the mobile phone also receives the return connection broadcast, the mobile phone does not establish a connection with the television because the distance between the mobile phone and the television exceeds the target distance.

The method provided by the embodiment of the application can be applied to scenes for controlling the household appliances. For example, the first device is a mobile phone, the second device is a television, the third device is an electric lamp, the user establishes connection with the television through the mobile phone, so that television channels are switched through the mobile phone, and establishes connection with the electric lamp through the mobile phone, so that the user turns on the lamp through the mobile phone. Due to the fact that the connection between the mobile phone and the television and the electric lamp is abnormally disconnected due to the automatic restart of the mobile phone, in this case, the mobile phone sends back the continuous broadcast after being restarted. Optionally, the loopback broadcast is used to request that a home appliance that has been connected to the mobile phone and is not currently connected to the mobile phone is connected to the mobile phone, and then the electric lamp and the television respectively establish connection to the mobile phone after receiving the loopback broadcast. Optionally, the reconnection broadcast is used for requesting a connection with the mobile phone, and an electric lamp which is not currently connected with the mobile phone establishes a connection with the mobile phone, so that after receiving the reconnection broadcast, the electric lamp determines that the electric lamp meets a reconnection condition, and then establishes a connection with the mobile phone. After the television receives the reconnection broadcast, the type of the equipment is determined to be not consistent with the type of the equipment which is allowed to be reconnected with the mobile phone, and then the television is determined not to meet the reconnection condition, so that the connection with the mobile phone is not established.

For another example, the reconnection condition includes that the device establishing reconnection with the first device is connected with the first device, the device is not currently connected with the first device, and the distance between the device and the first device is not greater than the target distance, then only the device having been connected with the first device, which has been currently disconnected, and the distance between the device and the first device is not greater than the target distance, can establish connection with the first device. Then, taking the first device as a home appliance and the second device as a mobile phone as an example, the user holds the mobile phone and moves from room a to room B, and the mobile phone is disconnected from the home appliance in room a because the mobile phone is far away from the home appliance in room a. And after the user arrives at the room B, the mobile phone is connected with the household appliances in the room B, and when the subsequent user returns to the room A from the room B, the mobile phone receives the back connection broadcast sent by the household appliances in the room A and is connected with the household appliances in the room A again. Similarly, when the user moves from room a to room B, the connection with the household appliance in room a is disconnected, and the user connects to the household appliance in room B based on the back connection broadcast sent by the household appliance in room B. Therefore, the mobile phone is automatically connected with the household appliance in the current room, and the user can conveniently control the household appliance.

The method provided by the embodiment of the present application can also be applied to other scenarios, and the embodiment of the present application does not limit this.

Fig. 2 shows a flowchart of a device connection method provided in an exemplary embodiment of the present application, and referring to fig. 2, the method is interactively performed by a first device and a third device, and the method includes:

201. the method comprises the steps that under the condition that connection between first equipment and second equipment is abnormally disconnected, a reconnection condition is obtained, and the reconnection condition is a condition which needs to be met by equipment which establishes reconnection with the first equipment.

Here, the connection back refers to a process of connecting two devices that have been connected but disconnected again. Optionally, the reconnection condition is that the first device currently obtains from the server, or the reconnection condition is stored in the first device in advance, or the first device receives a currently input reconnection condition. For example, in the case where the connection between the first device and the second device is abnormally disconnected, the first device displays a loop-back condition input interface, and receives a loop-back condition input at the loop-back condition input interface. Or, the first device receives the input voice information and identifies the reconnection condition in the voice information under the condition that the connection between the first device and the second device is abnormally disconnected. Of course, the first device can also obtain the reconnection condition in other ways, which is not limited in this embodiment of the application.

In a possible implementation manner, in the case that the connection between the first device and the second device is abnormally disconnected, acquiring the reconnection condition includes: and the first equipment acquires the reconnection condition under the condition that the target instruction is not received and the connection between the first equipment and the second equipment is disconnected. Wherein the target instruction indicates to disconnect the connection between the first device and the second device.

In the embodiment of the application, the first device does not receive the instruction indicating to disconnect the connection between the first device and the second device, so that the connection between the first device and the second device is disconnected, the connection can be objectively shown to be abnormally disconnected, in this case, the connection sending-back broadcast is sent to realize the connection back between the devices, and the connection back operation can be avoided under the condition that the user normally disconnects the connection between the devices, so that the interference to the user is caused.

202. The first device sends back a reconnection broadcast based on the reconnection condition, wherein the reconnection broadcast is used for requesting a third device meeting the reconnection condition to establish connection with the first device.

Optionally, the backhaul broadcast is a BLE (Bluetooth Low Energy) broadcast or other broadcast. Optionally, the type character is carried in the backhaul broadcast, and the device receiving the backhaul broadcast determines the type of the backhaul broadcast based on the type character, so as to parse the backhaul broadcast based on the type. Optionally, the backhaul broadcast is a Device ID Filter (a type of bluetooth low energy broadcast).

Optionally, when the connection between the first device and the second device is abnormally disconnected, the first device obtains the connection-back condition through an application in the first device, and then calls a connection service module in the first device through the application to send back the connection broadcast. Wherein the application is an application that uses the connection to transfer data. The connection service module is a module in the first device for establishing a connection between the electronic devices.

In a possible implementation manner, the reconnection condition includes that the device which establishes the reconnection with the first device is connected with the first device, and the device is not connected with the first device currently, so that the subsequent devices which are connected with the first device but disconnected can be connected with the first device again.

In one possible implementation, the tieback condition further comprises at least one of:

(1) in at least one device which is connected with the first device and is not connected with the first device currently, a disconnection time point corresponding to a device which establishes a loop connection with the first device is closest to or farthest from the current time point, and the disconnection time point is a time point when the device is disconnected from the first device.

(2) The corresponding disconnection time point of the device is in a target time period, and the target time period is any time period, for example, 7-12 pm.

(3) The type of the device is a target type. Wherein the target type can be set to any type, such as electric lamp, mobile phone, computer, etc.

(4) The distance between the device and the first device is not greater than the target distance. Wherein the target distance can be set to any distance, e.g. 1 meter, 2 meters, etc.

(5) The device is at a target location of the first device. The target direction can be set to any direction, for example, left front, rear, and the like.

In the embodiment of the application, the reconnection conditions are set from a plurality of angles, such as time of disconnection from the first device, distance from the first device, orientation relative to the first device, and device type, so that the device for performing reconnection with the first device can be selected from the plurality of angles, and more accurate reconnection is realized.

203. And the third equipment receives the back-connection broadcast sent by the first equipment.

The third device is any device except the first device, optionally, the third device is the second device, or the third device includes the second device and other devices.

204. And the third equipment establishes connection with the first equipment under the condition that the loop-back condition is met.

Optionally, the type of connection established between the third device and the first device is any type, for example, the third device establishes a BLE connection with the first device, establishes a P2P (Peer-to-Peer) connection with the first device based on the BLE connection, or establishes a WLAN (Wireless Local Area Network) connection with the first device based on the BLE connection.

For example, if the loopback condition is that the device establishing the loopback with the first device is connected with the first device and the device is not currently connected with the first device, the third device establishes connection with the first device as long as it is determined that the third device has been connected with the first device and is not currently connected with the first device. For another example, if the reconnection condition is that the device establishing reconnection with the first device is connected with the first device, the device is not currently connected with the first device, and the device is a television, the third device determines that the third device has been connected with the first device, is not currently connected with the first device, and establishes connection with the first device if the device type of the third device is a television.

It should be noted that the steps executed by the first device and the third device may independently become an embodiment, that is, the steps 201 and 202 may independently become an embodiment, and the steps 203 and 204 may independently become an embodiment.

Fig. 3 is a flowchart illustrating a method for device connection provided in an exemplary embodiment of the present application, and referring to fig. 3, the method is performed by a first device and a third device interactively, in the method, a backhaul broadcast carries an identifier of a device that meets a backhaul condition, and a device that receives the backhaul broadcast determines whether to establish a connection with the first device based on the identifier. The method comprises the following steps:

301. the method comprises the steps that under the condition that connection between first equipment and second equipment is abnormally disconnected, a reconnection condition is obtained, and the reconnection condition is a condition which needs to be met by equipment which establishes reconnection with the first equipment.

Please refer to step 201 above, and details of this step are not repeated here.

302. The first device determines an identity of a third device that satisfies the loopback condition.

In a possible implementation manner, the first device obtains the connection record of the first device, and queries the identifier of the third device meeting the reconnection conditions from the connection record, so that the identifier of the third device meeting the reconnection conditions can be determined quickly and accurately by means of the connection record.

Wherein the connection record includes an identification of historical devices that have established a connection with the first device. Optionally, the connection record further includes other information, for example, a current connection state between the historical device that has established a connection with the first device and the first device, a time point when the historical device establishes a connection with the first device, a time point when the connection is disconnected, a connection manner between the historical device and the first device, a device type of the historical device, and the like, which is not limited in this embodiment of the application.

In one possible implementation, the loopback condition includes that the device establishing the loopback connection with the first device is connected with the first device, and the device is not currently connected with the first device. Because the connection record records the identifier of the historical device which has established connection with the first device, the first device queries the identifier of the historical device which is in a corresponding connection state and is not connected from the connection record, and the queried identifier is the identifier of the third device which meets the reconnection condition.

In a possible implementation manner, the reconnection condition further includes that, in at least one device which is connected with the first device and is not currently connected with the first device, the disconnection time point corresponding to the device which establishes the reconnection with the first device is closest to or farthest from the current time point. Correspondingly, the first device selects the identifier of the history device closest to the current time point from the disconnection time points based on the disconnection time points corresponding to the identifiers of the history devices in the connection record, and the identifier of the history device is the identifier of the third device meeting the reconnection condition.

In one possible implementation, the reconnection condition further includes that the disconnection time point corresponding to the device establishing the reconnection with the first device is within the target time period. Correspondingly, the first device selects the identifier of the historical device of the disconnection time point in the target time period from the disconnection time points corresponding to the identifiers of the historical devices in the connection record, wherein the identifier of the historical device is the identifier of the third device meeting the reconnection condition. By restricting the devices that are looped back from the time dimension, devices that are not allowed to be looped back in the time dimension can be excluded, thereby reducing performance consumption on the devices.

In one possible implementation, the loopback condition further includes that the type of the device establishing the loopback connection with the first device is the target type. Correspondingly, the first device queries the identifier of the historical device with the corresponding connection state being unconnected from the connection record, and then determines the identifier of the historical device with the corresponding device type being the target type from the queried identifier of the historical device, so that the identifier is the identifier of the third device meeting the reconnection condition.

In one possible implementation manner, the determining, by the first device, an identifier of a third device that satisfies the backhaul condition includes: the first device determines an identification of a target number of third devices that satisfy the reconnection condition. For example, the first device randomly selects the identities of the target number of third devices from the identities of the third devices that satisfy the reconnection condition. For another example, the first device selects, from the identifiers of the third devices that satisfy the loop back condition, the identifiers of the third devices that are closest to the current time point from the disconnection time point of the first device by the target number. For another example, the reconnection condition includes that the device establishing reconnection with the first device is connected with the first device, the device is not currently connected with the first device, and the type of the device is an electric lamp, then the first device selects the identification of the target number of electric lamps from the identifications of the electric lamps which are connected with the first device and are not currently connected. Wherein the target number can be set to any number, e.g. 3, 4, etc.

In the embodiment of the application, because the device receiving the loopback broadcast establishes connection with the first device when determining that the loopback broadcast includes the identifier of the device, the number of the identifiers of the third devices meeting the loopback condition is determined, so that the limitation of the number of the devices establishing the loopback with the first device is realized, and the flexibility of establishing connection among the devices is improved.

303. The first device sends back a loopback broadcast, the loopback broadcast comprises an identifier of the third device, and the loopback broadcast is used for requesting the third device meeting the loopback condition to establish connection with the first device.

304. And the third equipment receives the reconnection broadcast sent by the first equipment, wherein the reconnection broadcast comprises the identification of the equipment meeting the reconnection conditions.

Optionally, the backhaul broadcast further includes an identifier of the first device, a connection mode of the first device, and the like.

305. The third device establishes a connection with the first device if the backhaul broadcast includes an identification of the third device.

For example, the loopback broadcast includes three electric lamp identifiers, and three electric lamps corresponding to the three electric lamp identifiers establish a connection with the first device when the loopback broadcast is received.

In the embodiment of the application, the identifier of the third device meeting the reconnection conditions is determined by the first device sending the broadcast, and the identifier of the third device is carried in the reconnection broadcast, so that after the third device receives the reconnection broadcast, the third device can know whether the third device meets the reconnection conditions by only determining whether the reconnection broadcast comprises the identifier of the third device, the efficiency of determining whether the third device meets the reconnection conditions is improved, and the consumption of the performance of the third device is reduced.

Fig. 4 is a flowchart illustrating a method for connecting devices according to an exemplary embodiment of the present application, and referring to fig. 4, the method is performed interactively by a first device and a third device, in which method, a backhaul broadcast carries a backhaul condition, and a device receiving the backhaul broadcast determines whether to establish a connection with the first device based on the backhaul condition. The method comprises the following steps:

401. the method comprises the steps that under the condition that connection between first equipment and second equipment is abnormally disconnected, a reconnection condition is obtained, and the reconnection condition is a condition which needs to be met by equipment which establishes reconnection with the first equipment.

Please refer to step 201 above, and details of this step are not repeated here.

402. The first device sends a backhaul broadcast including a backhaul condition, and the backhaul broadcast is used to request a third device satisfying the backhaul condition to establish a connection with the first device.

403. And the third equipment receives the back-connection broadcast sent by the first equipment.

404. And the third equipment establishes connection with the first equipment under the condition that the loop-back condition is met.

In one possible implementation, the loopback condition includes that the device establishing the loopback connection with the first device is connected with the first device, and the device is not currently connected with the first device. Correspondingly, the third device establishes connection with the first device under the condition that the loop-back condition is met, and the connection establishment method comprises the following steps: the third device obtains a connection record of the third device, wherein the connection record comprises an identifier of a historical device which is connected with the third device and a current connection state of the historical device and the third device, and the third device establishes connection with the first device when the third device determines that the connection record comprises the identifier of the first device and the first device is not connected with the third device currently. Therefore, the third equipment can quickly and accurately determine whether the third equipment meets the reconnection conditions or not by virtue of the connection records, and establishes connection with the first equipment under the condition that the reconnection conditions are met.

In a possible implementation manner, the reconnection condition further includes that the type of the device establishing the reconnection with the first device is a target type, and accordingly, the establishing of the connection with the first device by the third device if the reconnection condition is met includes: and the third equipment acquires the equipment type of the third equipment under the condition that the third equipment is determined to be connected with the first equipment and is not connected with the first equipment currently, and establishes connection with the first equipment under the condition that the equipment type belongs to the target type. The method can effectively improve the robustness of connection and reduce the occurrence of misconnection operation by limiting the types of the devices capable of being connected back.

In a possible implementation manner, the reconnection condition further includes that a disconnection time point corresponding to the device establishing reconnection with the first device is within a target time period, and accordingly, the establishing of the connection with the first device by the third device if the reconnection condition is met includes: and the third equipment establishes connection with the first equipment within the target time period after determining that the disconnection time point of the third equipment and the first equipment is within the target time period. The method can eliminate the devices which are not allowed to be connected back in the time dimension by limiting the devices for connecting back from the time dimension, thereby reducing the performance consumption of the devices.

In another possible implementation manner, the reconnection condition further includes that a distance between the device establishing the reconnection with the first device and the first device is not greater than a target distance, and accordingly, the establishing of the connection with the first device by the third device under the condition that the reconnection condition is met includes: the third equipment determines the received signal strength of the back-connection broadcast under the condition that the third equipment is connected with the first equipment and is not connected with the first equipment currently; determining a distance between itself and the first device based on the received signal strength; and establishing connection with the first equipment under the condition that the distance is not greater than the target distance.

In another possible implementation manner, the loopback condition further includes a target orientation of the device in the first device, the device in the loopback connection with the first device, and accordingly, the third device establishes a connection with the first device if the loopback condition is met, including: the third equipment determines the position of the third equipment relative to the first equipment based on the received loop connection broadcast under the condition that the third equipment is determined to be connected with the first equipment and is not connected with the first equipment currently; in the case where the orientation coincides with the target orientation, a connection is established with the first device. Optionally, the third device determines its position relative to the first device by UWB (Ultra Wide Band) technology based on the received backhaul broadcast.

It should be noted that the above-mentioned various loop-back conditions can be combined in any manner, and for example, the loop-back conditions include: the device which establishes the loop connection with the first device is connected with the first device, the device is not connected with the first device currently, the type of the device is a target type, and the distance between the device and the first device is not more than the target distance. Correspondingly, the third device acquires the device type of the third device when the third device is determined to be connected with the first device and not connected with the first device currently, and determines the received signal strength of the back connection broadcast when the device type belongs to the target type; and determining the distance between the first device and the self based on the received signal strength, and establishing connection with the first device under the condition that the distance is not more than the target distance.

In the embodiment of the application, the first device sends the loop connection broadcast including the loop connection condition, and the device receiving the loop connection broadcast determines whether the device meets the loop connection condition based on the loop connection condition, so that the first device sending the loop connection broadcast does not need to determine the identifier of the device meeting the loop connection condition, and the consumption of the performance of the first device is reduced.

Please refer to step 201 above, and details of this step are not repeated here.

502. The first device displays the broadcast confirmation information and sends back the continuous broadcast in response to the confirmation operation of the broadcast confirmation information, or the first device sends back the continuous broadcast without displaying the broadcast confirmation information, and the continuous broadcast is used for requesting a third device meeting the continuous broadcast condition to establish connection with the first device.

Optionally, the first device displays a broadcast confirmation popup, where the popup includes a confirmation control, and the first device sends back a continuous broadcast in response to a trigger operation on the confirmation control.

In the embodiment of the application, the broadcast confirmation information is displayed, and the continuous broadcast is sent back only when the user confirms the broadcast confirmation information, so that the option of whether the user performs the continuous broadcast is given to the user, the process of establishing the continuous broadcast can be avoided when the user does not agree, the initiation of the current continuous broadcast process is ensured to meet the requirements of the user, the user experience is improved, and the user viscosity can be improved.

In the embodiment of the application, in consideration of the situation that under the condition that the connection between the devices is more, if the user needs to manually send the connection back each time, the operation burden of the user is increased, therefore, the first device directly sends the connection broadcast back under the condition that the broadcast confirmation information is not displayed, the user operation can be reduced, the user experience is improved, and the user viscosity is improved.

503. And the third equipment receives the reconnection broadcast sent by the first equipment, wherein the reconnection broadcast also comprises second indication information, and the second indication information indicates the third equipment to display reconnection confirmation information.

And the reconnection confirmation information is used for the third equipment to confirm the connection establishment with the first equipment.

504. And the third equipment displays the reconnection confirmation information under the condition that the third equipment meets the reconnection condition, and responds to the confirmation operation of the reconnection confirmation information to establish connection with the first equipment.

The loopback confirmation information is used for the third equipment to confirm the connection establishment with the first equipment. Optionally, the first device displays a loopback confirmation popup, where the popup includes a confirmation control, and the third device establishes a connection with the first device in response to a trigger operation on the confirmation control. Optionally, when the third device receives a loopback broadcast sent by multiple devices at the same time, the third device displays the identifiers of the multiple devices in the popup window, and a confirmation control corresponding to the identifier of each device, and establishes a connection with the device in response to a trigger operation on the confirmation control corresponding to the identifier of any device in the loopback popup window.

Fig. 6 is a schematic diagram of a reconnect confirmation popup, and referring to fig. 6, the reconnect confirmation popup displays a device a, a confirmation control, and a cancellation control, where "reconnect" is displayed on the confirmation control, and a user triggers the confirmation control to establish a connection with the device a. The user triggers the cancel control to refuse to establish a connection with device a and close the pop-up window. It should be noted that, in addition to the device a, other device identifiers are also displayed in the popup, and the user may perform a sliding operation on the device identifier in the loopback confirmation popup, so that identifiers of other devices are completely displayed. After the identifiers of other devices are completely displayed, the reconnection control is triggered, and then the third device can be triggered to establish connection with the device.

In the embodiment of the application, the second indication information is carried in the reconnection broadcast to indicate the third device meeting the reconnection condition to display the reconnection confirmation information, and the connection is established with the first device only when the user confirms the reconnection confirmation information, so that the connection with the first device can be avoided being reestablished without the user agreement, the connection with the first device is ensured to be currently established according with the user requirement, and the user viscosity can be improved.

In one possible implementation, the reconnection broadcast includes not the second indication information but the first indication information indicating that the third device does not display the reconnection confirmation information. Accordingly, the third device does not display the reconnection confirmation information and establishes a connection with the first device in the case where the reconnection condition is satisfied.

In the embodiment of the application, in consideration of a scene that the connection between the devices is more, if the user needs to manually trigger the reconnection every time, the operation burden of the user is increased, and therefore, the first indication information is carried in the reconnection broadcast to indicate that the third device meeting the reconnection condition does not display the reconnection confirmation information, so that the third device can establish the connection with the first device without the user confirming the reconnection, the user operation can be reduced, and the user stickiness is improved.

It should be noted that the first device sends back the connectively broadcast without displaying the broadcast confirmation information, and the third device directly establishes a connection with the first device without displaying the connectively confirmation information when the connectively return condition is met, where this connection mode may be called silent connectively return, that is, the connectively return between the two devices is implemented in a mode without interface disturbance and without the need of the user to perform a trigger operation. In consideration of future Internet of everything interconnection stage, the types and the number of IOT (Internet of Things) devices connected by common devices will increase explosively, and the number of connected IOT devices can reach hundreds or thousands. Even if only a small part of the data needs the user to perform the loop back operation, the heavy operation burden is also caused to the user, and therefore, the disturbance to the user can be greatly reduced by adopting the silent loop back connection mode. Moreover, the execution of silent reconnection can effectively reduce the connection time consumption perceived by the user, and even under the condition that the user does not perceive, the reconnection is realized, so that the user viscosity can be improved.

Optionally, it can also be determined whether the device employs a silent loop or a loop that requires a user to perform an operation according to the type of the device. For example, a PC (Personal Computer) uses a callback requiring a user to perform an operation, for example, a broadcast confirmation message is displayed during the connection process, and a tablet PC uses a silent callback, which is not limited in the embodiment of the present application.

In a possible implementation manner, in consideration of the fact that there are a plurality of third devices satisfying the loop-back condition, each of the third devices displays loop-back confirmation information, in order to reduce interference to the user, the first device transmits a confirmation information cancellation broadcast for requesting other third devices except for the third device that establishes a connection with the first device to cancel displaying the loop-back confirmation information after establishing a connection with any of the third devices based on the loop-back broadcast. Correspondingly, after the other third devices display the reconnection acknowledgement information, the reconnection acknowledgement information is cancelled and displayed under the condition that the acknowledgement information cancellation broadcast sent by the first device is received, so that the reconnection acknowledgement information displayed by each third device can automatically disappear after the first device establishes connection with any third device, a user does not need to cancel the display manually, and the user viscosity is improved. With continued reference to fig. 6, in a case where the third device simultaneously receives the back connection broadcasts transmitted by the multiple devices, and the back connection broadcasts transmitted by the multiple devices all include the second indication information, the third device displays the identifications of the multiple devices in the popup window, and in a case where the confirmation information cancellation broadcast transmitted by any one of the multiple devices is received, the identifications of the devices are cancelled to be displayed in the popup window. The third device closes the popup window upon receiving the acknowledgment information cancellation broadcast transmitted by each of the plurality of devices.

Referring to fig. 7, the three interfaces in the upper row of fig. 7 are the interfaces of a first device, and the three interfaces in the lower row are the interfaces of a second device. When the second device and the first device have established connection and the picture of the second device is projected in the first device, the connection between the first device and the second device is abnormally disconnected, at the moment, the first device displays an interface 1 in fig. 7, the interface comprises broadcast confirmation information, namely 'reconnection', a user triggers a control to 'reconnection', the first device sends back a connection broadcast, and an interface 2 in fig. 7 is displayed. The second device receives the reconnection broadcast, and displays an interface 4 in fig. 7 when determining that the second device meets the reconnection conditions, wherein the interface comprises a reconnection confirmation popup, the reconnection confirmation popup comprises an identifier of the first device and a reconnection confirmation control, a connection is displayed in the reconnection confirmation control, the user triggers the reconnection confirmation control, the second device can establish a connection with the first device, and the interface 5 in fig. 7 is displayed. Under the condition that the second device is successfully connected with the first device, the second device displays the interface 6 in fig. 7, and continues to project the picture in the first device, so that the interface displayed by the first device, that is, the interface 3 in fig. 7, is the same as the interface displayed by the second device at this time. The connection process needs the user to perform the reconnection operation, and it should be noted that, with reference to fig. 7, in the silent reconnection process, when the first device displays the interface 1 in fig. 7, the user does not need to trigger the "reconnection" control, and the first device sends back the reconnection broadcast. Alternatively, no "reconnect" control is displayed in the interface. After the first device sends back the connection broadcast, interface 2 in fig. 7 is still displayed. Moreover, after receiving the backhaul broadcast, the second device does not display the interface 4 in fig. 7 and the interface 5 in fig. 7, and after the second device is successfully connected with the first device, the second device directly displays the interface 6 in fig. 7, and continues to project the screen in the first device, so that the interface displayed by the first device at this time, that is, the interface 3 in fig. 7 is the same as the interface displayed by the second device. Or, in the silent reconnection process, after the second device is successfully connected with the first device, the interface 6 is not displayed, and the picture is continuously projected in the first device. Additionally, in the event of loss of silence back, the user may trigger a "reconnect" control in the first device, triggering the first device to resend the connection broadcast. And, in case of receiving the loop back broadcast, the second device does not perform silence loop back, but displays the interface 4 in fig. 7, and establishes connection with the first device again when the user triggers the "connect" control.
