Referring to fig. 2, an application scenario of interconnection between electronic devices according to an embodiment of the present application is provided.

Referring to fig. 2 (a), the user's mobile phone and the sports watch may be connected via bluetooth. In the process of a user wearing the sports watch to do sports, the sports watch collects sports data of the user, the sports watch can send the sports data of the user to the mobile phone in real time through Bluetooth connection, and the mobile phone can display the sports data of the user in real time.

Referring to fig. 2 (b), a user may leave a mobile phone at home while wearing a sports watch for outdoor sports. If the distance between the outdoor running place of the user and the home of the user exceeds the propagation distance of the Bluetooth, the Bluetooth connection between the sports watch of the user and the mobile phone of the user is disconnected, and the sports data collected by the sports watch of the user in real time cannot be transmitted to the mobile phone of the user in real time.

Referring to fig. 2 (c), when the user finishes the exercise and wears the sports watch to return to home, the sports watch of the user and the mobile phone of the user reestablish (recover) the bluetooth connection, and the sports watch of the user can transmit the exercise data in the exercise process to the mobile phone, so that the exercise data of the user can be displayed through the mobile phone.

However, in practical applications, after the user wears the sports watch and returns to home, the user picks up the mobile phone to view the sports data, and the mobile phone cannot display the sports data just taken out for sports.

Fig. 3 is an interface schematic diagram of a card of an exercise health application on a mobile phone displaying exercise data and an interface schematic diagram of a card of an exercise health application on a mobile phone not displaying the exercise data in time, which are provided in the embodiment of the present application.

In the embodiment of the application, a card of an exercise health application on a system desktop is used as an example for displaying exercise data, in practical application, an interface (an interface after the exercise health application is started) of the exercise health application or a negative one-screen interface and the like can be used, and the embodiment of the application does not limit the way in which a user views the exercise data.

Referring to fig. 3 (a), theoretically, when the user wears the sports watch and returns to home after sports, the sports watch of the user and the mobile phone of the user reestablish (recover) the bluetooth connection, the sports watch of the user transmits the sports data in the sports process to the mobile phone, and the mobile phone displays the sports data of the user through the sports health card.

Referring to fig. 3 (b), when the user finishes the exercise and returns to home after wearing the sports watch, the user picks up the mobile phone to view the exercise data, and the mobile phone cannot display the card for exercise health application and cannot display the exercise data during the exercise just going out. Of course, in practical applications, the mobile phone may also display the card for exercise health application, however, the mobile phone cannot display exercise data. The embodiment of the application does not limit the display time of the card applied to the sports health.

The reason why the case shown in (b) in fig. 3 occurs may be: the user wears the sports watch to finish sports and returns to home, when the user picks up the mobile phone to check sports data, the Bluetooth connection between the sports watch and the mobile phone is not recovered, and therefore the sports data in the sports watch is not synchronized into the mobile phone.

In order to solve the problem occurring in (b) of fig. 3, the following will analyze the reason why the bluetooth connection between the sports watch and the cellular phone cannot be restored in time.

The bluetooth includes: classic Bluetooth (e.g., BR, EDR, and AMP modes) and Bluetooth low energy (Bluetooth low energy).

Some electronic devices only support classic bluetooth, some electronic devices only support bluetooth low energy, and some electronic devices can support both classic bluetooth and bluetooth low energy, i.e. dual-mode bluetooth.

In general, bluetooth low energy has lower power consumption and lower battery requirements than classic bluetooth, so that the endurance of an electronic device using bluetooth low energy can be extended. Based on the above differences, classic bluetooth is more useful in audio scenarios, such as bluetooth phone answering, bluetooth headset, and bluetooth speaker scenarios. Bluetooth low energy is more often in battery powered occasions such as wearable equipment, thing networking device, body-building equipment, keyboard mouse. Of course, the classic bluetooth and bluetooth low energy application scenarios listed above are for example only.

Taking the scenario shown in fig. 2 as an example, the sports watch generally provides functions of talking and playing audio, so the sports watch generally supports classic bluetooth, and a bluetooth connection is established between the mobile phone and the sports watch through classic bluetooth. When the distance between the mobile phone and the sports watch is long and the classic Bluetooth connection between the mobile phone and the sports watch is disconnected, the sports watch serving as the slave device periodically sends back a connection request broadcast, and the mobile phone serving as the master device recovers the classic Bluetooth connection between the mobile phone and the sports watch after receiving the connection request broadcast. As described above, the classic bluetooth is relatively high in power consumption and relatively high in power consumption, so when the sports watch is applied to an electronic device with limited electric quantity, such as a battery, the transmission frequency of bluetooth broadcast is usually reduced (the transmission cycle is prolonged) to reduce the power consumption, which may result in that the classic bluetooth connection may not be immediately restored under the condition that the distance between the mobile phone and the sports watch satisfies the distance of bluetooth connection, and the natural sports watch may not synchronize the sports data to the mobile phone in time. From the perspective of a user, the card applied to sports health on the mobile phone cannot refresh and display sports data just outdoors in time.

Certainly, the above application scenarios only take the mobile phone and the sports watch as examples, and in practical applications, when the classic bluetooth connection is restored between two electronic devices connected by the classic bluetooth, both the two electronic devices can be connected by the bluetooth connection mode subsequently provided by the embodiment of the present application. In the following, the bluetooth connection method provided by the embodiment of the present application will be described with a mobile phone as a master device for bluetooth connection and a sports watch as a slave device for bluetooth connection. The master device may be denoted as a first electronic device, and the slave device that has established a bluetooth connection with the master device may be denoted as a bluetooth device, and of course, when there are a plurality of slave devices, the first bluetooth device and the second bluetooth device may be further used to distinguish different bluetooth devices, for example, the sports watch described above may be used as an example of the first bluetooth device.

In the embodiment of the application, in order to improve user experience, a user can check the motion data on the motion watch through the mobile phone in time, before the user checks the motion data through the mobile phone, the Bluetooth connection between the mobile phone and the motion watch needs to be restored in time, and the motion watch can synchronize the motion data to the mobile phone in time based on the restored Bluetooth connection.

Generally, the procedure of bluetooth backhaul is: the slave device (for example, the sports watch in the above scenario) periodically sends back the connection request broadcast, and after receiving the connection request broadcast sent by the slave device, the master device (the mobile phone in the above scenario) starts a connection back operation, so that the bluetooth connection is restored between the master device and the slave device.

Since the slave device increases the period of sending the connection request broadcast back to reduce power consumption, the bluetooth connection method provided in this embodiment of the present application no longer depends on the connection request broadcast of the slave device, but is implemented by a flowchart shown in the bluetooth connection manner shown in fig. 4. The bluetooth backhaul method shown in fig. 4 includes the following steps:

step S101, the mobile phone predicts that the user may check the motion data.

Step S102, after the situation that the user probably checks the motion data is judged, the mobile phone is used as the main equipment to actively initiate a connection back request.

And step S103, after the slave device receives the connection back request, the Bluetooth connection with the master device is recovered.

After the bluetooth connection is restored, the slave device synchronizes motion data to the master device based on the restored bluetooth connection. By the method, the Bluetooth connection between the mobile phone and the sports watch can be timely recovered under the condition that the user is predicted to possibly check the sports data, so that the sports watch can timely synchronize the sports data to the mobile phone, and the user can see the synchronized sports data when using the mobile phone.

As an implementation manner of step S101, when using the mobile phone, the user will take up the mobile phone first, then unlock the mobile phone, and finally use the mobile phone. When a user uses the mobile phone, the mobile phone usually displays the system desktop first, and the card applied to the sports health is displayed on the system desktop; therefore, it can be predicted that the user may view the exercise data through the monitored event (which may be denoted as the first event) that the user may use the mobile phone.

The events which are provided by the embodiment of the application and are possibly used by the user can comprise various events.

As an example, events in which a user may use a cell phone may include: the action that the mobile phone is picked up or turned over is recognized, or the operation that the mobile phone is unlocked is recognized.

Taking the action of identifying the mobile phone to be picked up or turned over as an example, an acceleration sensor and a gyroscope can be arranged in the mobile phone, and the acceleration sensor is used for determining the upward acceleration of the mobile phone so as to determine the action of picking up the mobile phone; and determining that the mobile phone has the action of turning over through the angular speed detected by the gyroscope.

Of course, in practical applications, a lifting recognition model may be further provided, the lifting recognition model does not depend only on the acceleration collected by the acceleration sensor, the input parameters of the lifting recognition model may further include the angular velocity collected by the gyroscope, and the lifting recognition model is used to recognize the action of lifting (lifting) the mobile phone.

Similarly, a roll-over recognition model may be provided, which not only depends on the angular velocity collected by the gyroscope, but also includes the acceleration collected by the acceleration sensor.

Certainly, in order to make the recognition more accurate, other input parameters may be set in the lifting recognition model and the turning recognition model, and the embodiment of the present application does not limit the specific implementation manner of recognizing the action of lifting or turning the mobile phone.

For example, the operation of identifying that the mobile phone is unlocked may be set in different identification modes based on different unlocking modes.

For example, when there is fingerprint unlocking for the mobile phone, the operation of identifying that the mobile phone is unlocked may be set as: the fingerprint unlocking area detects a pressing operation.

When the mobile phone is unlocked by the password, the operation of identifying that the mobile phone is unlocked can be set as follows: and displaying a password unlocking interface by the mobile phone.

When the mobile phone has physical key unlocking, the operation of identifying that the mobile phone is unlocked can be set as follows: and monitoring the pressing operation of the physical key for unlocking.

Of course, when the mobile phone may have multiple unlocking modes, detecting any operation that the mobile phone is unlocked may determine that the operation that the mobile phone is unlocked is recognized.

As an implementation manner of steps S102 and S103, when the master device actively initiates the connection back request, the connection back request may also be sent in a broadcast manner. In order to avoid establishing a bluetooth connection with other bluetooth devices (e.g., bluetooth keyboard, bluetooth mouse, etc.) within the broadcast coverage area that do not need to be connected, the request for a loopback needs to carry a unique identification of the slave device that needs to recover the bluetooth connection. After the master device sends the reconnection request broadcast, a plurality of slave devices (such as a sports watch, a Bluetooth keyboard and a Bluetooth mouse) in the broadcast coverage range can receive the reconnection request broadcast; a plurality of slave devices (such as a sports watch, a bluetooth keyboard and a bluetooth mouse) which receive the loopback request broadcast need to determine whether the unique identifier carried in the broadcast is consistent with the unique identifier of the device; and under the condition that whether the unique identification carried in the broadcast is consistent with the unique identification of the equipment is determined, the electronic equipment which is whether the unique identification carried in the broadcast is consistent with the unique identification of the equipment is used as the slave equipment to recover the Bluetooth connection with the master equipment. The unique identifier is used to distinguish different bluetooth devices, so the unique identifier may be the mac address of the bluetooth device.

In order to determine that the user can view the motion data synchronized with the sports watch when using the mobile phone by using the bluetooth connection method provided by the embodiment of the present application, the embodiment of the present application describes a time relationship between a process of the user taking the mobile phone to view the motion data and a process of the mobile phone returning by taking the mobile phone as an event that the user may view the motion data by detecting that the mobile phone is taken up or turned over.

Referring to fig. 5, a schematic diagram of a time relationship between a process of a user picking up a mobile phone to view motion data and a process of mobile phone connection back provided in an embodiment of the present application, where the process described in fig. 5 corresponds to a bluetooth connection back process represented by a scenario shown in (c) in fig. 2.

Wherein, from when the user begins to pick up the mobile phone, the connection back process between the mobile phone and the sports watch mainly comprises the following processes:

(1) Event recognition: the handset recognizes an event that the handset is lifted or flipped. Takes about 700-1000ms.

(2) Bluetooth loop connection: and the mobile phone establishes Bluetooth connection with the sports watch based on the stored MAC address of the sports watch. It took about 1s.

(3) Data synchronization: the sports watch synchronizes the sports data to the handset. Takes less than about 500ms.

(4) Card refreshing: the card of the exercise health application on the mobile phone is refreshed based on the synchronized exercise data. Takes less than about 500ms.

In summary, it takes about 2.7s to 3s from the time the user starts to pick up the mobile phone to the sports health card on the mobile phone to successfully refresh the sports data.

There are mainly the following processes from the user starting to pick up the phone to the user starting to view the card of the sports health application on the phone:

(1) The user starts picking up the mobile phone until the user starts unlocking the mobile phone. For about 1s.

(2) The user starts to unlock the mobile phone and the mobile phone is successfully unlocked. If the face unlocking is adopted, the time consumption is usually less than 1s; if the fingerprint is adopted to press for unlocking, the time consumption is usually less than 800ms; if the unlocking is input by a password or a gesture, the time consumption is usually less than 2s. In fig. 5, the process takes about 1s when the human face is unlocked, for example.

(3) The unlocking of the mobile phone is successfully completed by displaying the desktop of the mobile phone, and the time consumption is usually less than 700ms.

In summary, it takes about 2.7 seconds from the user picking up the cell phone to starting to view the card of the sports fitness application on the cell phone. Considering different unlocking modes, it takes about 2.5s to 3.7s.

It will be appreciated that while in some extreme cases the user 'S viewing time is slightly less than the walking time, 1S is the limit at which the user' S operational mind remains uninterrupted, as shown by the user experience human factor study results. Therefore, when the user viewing time is slightly less than the step time within 1s, the interruption of the user operation on the cardiac flow is not caused.

For a clearer understanding of the bluetooth connection method provided in the embodiment of the present application, reference may be made to fig. 6, where fig. 6 is another schematic flowchart of the bluetooth connection method provided in the embodiment of the present application, and the schematic flowchart may correspond to the scenarios shown in fig. 2 (a) and fig. 2 (b).

In the bluetooth connection method provided in the embodiment of the present application, before the mobile phone really sends back the connection request broadcast, the following steps are further present:

s201, the mobile phone and the sports watch establish Bluetooth connection, and the mobile phone registers Bluetooth connection state change monitoring service.

After the mobile phone and the sports watch establish Bluetooth connection, a Bluetooth connection state change monitoring service is registered, and the Bluetooth connection state change monitoring service is used for monitoring state change of the Bluetooth connection between the mobile phone and the sports watch.

S202, the mobile phone monitors that the mobile phone and the Bluetooth watch are disconnected in Bluetooth connection based on the registered Bluetooth connection state change monitoring service, and the mobile phone registers the action monitoring service.

The action monitoring service is used for monitoring whether the mobile phone is lifted or overturned.

S203, the mobile phone identifies whether the mobile phone is lifted or turned over based on the registered motion monitoring service.

After the identification result of step S203 is that the mobile phone is lifted or turned over, which indicates that the mobile phone predicts that the user may view the motion data in step S101, the steps S102 and S103 will be continued.

For a clearer understanding of the above embodiments, a flowchart of the bluetooth connection method is illustrated with reference to fig. 7.

S301, the Bluetooth connection is established between the mobile phone and the Bluetooth device for the first time, and the Bluetooth type and the device type of the Bluetooth device which establishes the Bluetooth connection with the mobile phone are obtained.

In the embodiment of the application, when the mobile phone is connected with the Bluetooth device for the first time, the mobile phone needs to be paired, and after the pairing is successful, the mobile phone and the Bluetooth device successfully establish the Bluetooth connection. When the mobile phone establishes the Bluetooth connection with the Bluetooth equipment again, the pairing process is not needed any more. Therefore, in the embodiment of the present application, the mobile phone may determine whether to establish a bluetooth connection with the bluetooth device for the first time through whether a pairing process exists.

Of course, in practical application, it may also be determined whether to establish bluetooth connection with the bluetooth device for the first time in another manner.

S302, whether the Bluetooth type is classic Bluetooth or dual-mode Bluetooth and whether the device type is a preset device type is judged.

And S303, if the Bluetooth type is classic Bluetooth or dual-mode Bluetooth and the equipment type is a preset equipment type, storing the mac address of the Bluetooth equipment in the mobile phone.

In this embodiment of the present application, one or more device types are preset, for example, the preset device type (which may be denoted as a first type) may include: a wearable device. When the device type is any one of the preset device types and the bluetooth type is the classic bluetooth or the dual-mode bluetooth, it can be determined that the bluetooth device currently establishing the bluetooth connection with the mobile phone is suitable for the bluetooth backhaul method provided by the embodiment of the present application. Therefore, it is necessary to store the mac address of the bluetooth device to establish a bluetooth connection based on the mac address at a later time.

In the embodiment of the application, when the mac address of the bluetooth device is stored, the device type and the bluetooth type of the bluetooth device may be stored in an associated manner.

S304, the mobile phone monitors the state change of the Bluetooth connection.

In the embodiment of the application, no matter the current connection between the mobile phone and the bluetooth device is the first connection or the non-first connection, the state change of the bluetooth connection needs to be monitored after the bluetooth connection is established. Therefore, before step S304, it is also possible to include:

step S401, the Bluetooth connection is not established for the first time by the mobile phone and the Bluetooth device.

After step S304, the following steps are also included:

s305, the mobile phone monitors that the Bluetooth connection with the Bluetooth equipment is disconnected.

S306, judging whether the Bluetooth type of the disconnected Bluetooth equipment is classic Bluetooth or dual-mode Bluetooth or not, and whether the equipment type is the preset equipment type or not.

In the embodiment of the application, after the bluetooth connection (first time and non-first time) is established between the mobile phone and the bluetooth device, the change of the bluetooth connection state is monitored. Therefore, after the mobile phone monitors that the bluetooth connection of the bluetooth device is disconnected, it needs to determine whether the bluetooth type of the disconnected bluetooth device is classic bluetooth or dual-mode bluetooth, and whether the device type is a preset device type, so as to determine whether to register an action monitoring service.

S307, if the Bluetooth type of the currently disconnected Bluetooth device is classic Bluetooth or dual-mode Bluetooth and the device type is a preset type, registering an action monitoring service, wherein the action monitoring service is used for determining whether the mobile phone has a lifting or overturning action based on the angular velocity monitored by the gyroscope and the acceleration monitored by the acceleration sensor.

In this embodiment of the present application, when the bluetooth type of the currently disconnected bluetooth device is a classic bluetooth or a dual-mode bluetooth, and the device type is a preset device type, the bluetooth device is only applicable to the bluetooth backhaul method provided in this embodiment of the present application. Therefore, the action monitoring service is registered to determine whether the mobile phone is lifted or turned over by the action monitoring service.

S308, the mobile phone judges whether the mobile phone is in lifting or turning action through the action monitoring service.

S309, when the mobile phone is determined to be lifted or turned over, searching the mac address of the Bluetooth device with the preset device type, the Bluetooth type being classical Bluetooth or dual-mode Bluetooth and the connection state being disconnected from the stored mac address list.

In this embodiment of the present application, the bluetooth device corresponding to the mac address that is searched for is a bluetooth device that is suitable for the bluetooth backhaul method provided in this embodiment of the present application, and therefore, the device type of the bluetooth device corresponding to the mac address that is searched for is a preset device type, and the bluetooth type is classic bluetooth or dual-mode bluetooth.

In addition, the user wears the sports watch to send the bluetooth broadcast periodically, but the period is long, so when the user wears the sports watch to return to the space where the mobile phone is located, the sports watch may be right at the moment of sending the bluetooth broadcast, or the time before the mobile phone is determined to be lifted or turned over, the sports watch just sends the bluetooth broadcast, and the mobile phone establishes the bluetooth connection with the sports watch based on the bluetooth broadcast. In this case, the handset no longer needs to initiate a reconnect request broadcast, so in the event that the handset is determined to be in a lift or flip action, the mac address currently disconnected from bluetooth is looked up from the list.

In the embodiment of the present application, one or more mac addresses that meet the requirement and are found by the mobile phone may be found.

As an example of finding a mac address that meets the requirement, one bluetooth device that meets the condition (the device type is a preset device type, and the bluetooth type is classic bluetooth or dual-mode bluetooth) is stored in the mobile phone, and accordingly, one mac address is stored. After the mobile phone is disconnected from the Bluetooth device corresponding to the mac address, if the mobile phone is monitored to be lifted or turned, the mac address of the Bluetooth device is obtained from the mac address list.

As another example of finding a mac address that meets the requirement, the number of bluetooth devices that satisfy the condition (the device type is the preset device type, and the bluetooth type is classic bluetooth or dual-mode bluetooth) stored in the mobile phone is two, and correspondingly, two mac addresses are stored. After the mobile phone is disconnected from the Bluetooth device corresponding to one mac address, the Bluetooth device corresponding to another mac address still has Bluetooth connection; if the mobile phone is monitored to have the lifting or turning action, the mac address of the Bluetooth device disconnected from the Bluetooth connection is obtained from the mac address list, and the mac address of another Bluetooth device still connected with the mobile phone by the Bluetooth cannot be found.

As an example of finding two mac addresses that meet the requirement, two bluetooth devices that satisfy the condition (the device type is a preset device type, and the bluetooth type is classic bluetooth or dual-mode bluetooth) are stored in the mobile phone, and correspondingly, two mac addresses are stored. After the mobile phone and the two Bluetooth devices are disconnected, if the situation that the mobile phone is lifted or overturned is monitored, mac addresses of the two Bluetooth devices disconnected from the Bluetooth are obtained from the mac address list.

Other examples of finding two satisfactory mac addresses and examples of finding more than two satisfactory mac addresses are not given.

And S310, the mobile phone broadcasts a Bluetooth connection request based on the searched mac address.

Under the condition that the mobile phone finds a mac address meeting the requirement, a Bluetooth connection request is broadcasted based on the found mac address, and the Bluetooth connection request carries the mac address.

And under the condition that the mobile phone finds a plurality of mac addresses meeting the requirements, broadcasting the Bluetooth connection request based on the plurality of found mac addresses. For example, a bluetooth connection request carrying the mac address is generated based on each mac address broadcast, and then a plurality of bluetooth connection requests corresponding to a plurality of mac addresses are broadcast.

After step S310, the following steps are also included (the illustration is not shown):

s311, the bluetooth device receiving the bluetooth connection request resumes the bluetooth connection with the mobile phone sending the connection request when the mac address is consistent with the mac address of the bluetooth device.

In this embodiment of the present application, if a bluetooth connection request broadcast sent by a mobile phone is a broadcast corresponding to multiple bluetooth connection requests corresponding to multiple mac addresses, and possibly a certain bluetooth device corresponding to a certain mac address or certain mac addresses are within a coverage range of the broadcast, the broadcast can be received, and bluetooth connection can be resumed. If the bluetooth device corresponding to a mac address or mac addresses is not within the coverage of the broadcast, the broadcast cannot be received, and the bluetooth connection will not be restored.

And S312, after the Bluetooth device is confirmed to recover the Bluetooth connection with the mobile phone, the Bluetooth device sends the motion data to the mobile phone.

Taking the sports watch as an example, the sports watch synchronizes the motion data to the mobile phone, and if the bluetooth device is another device, the sports watch can send other information related to the bluetooth device to the mobile phone.

The embodiment of the application focuses on how to quickly recover the Bluetooth connection between the mobile phone and the Bluetooth device, and the interaction between the mobile phone and the Bluetooth device after the Bluetooth connection is recovered is not limited.

And S313, after the mobile phone receives the exercise data, updating the content in the exercise health application card displayed on the desktop.

And S314, when the mobile phone is unlocked and the mobile phone displays the desktop, displaying the contents in the card of the exercise health application on the desktop as the exercise data synchronized with the exercise watch.

In the embodiment shown in fig. 7, after the bluetooth connection is established between the mobile phone and the bluetooth device, if the mobile phone determines that the bluetooth device currently establishing the bluetooth connection with the mobile phone is not the first bluetooth connection, the steps S302 and S303 of "acquiring the bluetooth type and device type of the bluetooth device establishing the bluetooth connection with the mobile phone" in step S301 are no longer required.

However, in practical applications, the bluetooth connection method provided in this embodiment of the present application may not be preset in a mobile phone when the mobile phone is shipped from a factory, or the mobile phone may have a function corresponding to the bluetooth connection method provided in this embodiment of the present application through a system upgrade manner or an application installation manner that provides the function after the user uses the mobile phone for a period of time. Therefore, the embodiment of the present application further provides another way to generate the mac address list (the mac address list may be a list corresponding to the mac address, the bluetooth type, and the device type of the bluetooth device stored in step S303 in fig. 7).

Referring to fig. 8, a schematic flowchart of another process for storing the mac address of the bluetooth device according to the embodiment of the present application is provided.

S501, the mobile phone and the Bluetooth device establish Bluetooth connection.

S502, after the Bluetooth connection is established between the mobile phone and the Bluetooth device, the Bluetooth type and the device type of the Bluetooth device which establishes the Bluetooth connection with the mobile phone are obtained.

In the embodiment of the application, whether the Bluetooth connection between the mobile phone and the Bluetooth device is the first connection or the non-first connection does not need to be judged, and the Bluetooth type and the device type of the Bluetooth device establishing the Bluetooth connection with the mobile phone can be acquired on the basis that the first connection and the non-first connection do not need to be judged.

S503, the mobile phone judges whether the Bluetooth type of the Bluetooth equipment is classic Bluetooth or dual-mode Bluetooth and whether the equipment type is preset equipment type.

S504, if the Bluetooth type is classic Bluetooth or dual-mode Bluetooth and the device type is a preset device type, whether the mac address of the Bluetooth device is stored in the mobile phone or not is judged.

S505, if the mac address of the bluetooth device is not stored in the mobile phone, the mac address of the bluetooth device may be stored in the mobile phone. And simultaneously, the device type and the Bluetooth type of the Bluetooth device are stored in an associated manner.

If the mac address of the bluetooth device is already stored in the mobile phone, the mac address does not need to be stored again.

After step S505, step S304 to step S314 may be continuously performed, which is not described in detail in this embodiment of the application.

In the embodiment shown in FIG. 7, the steps performed prior to determining whether to register for the action listening service include:

after monitoring that the Bluetooth connection between the mobile phone and the Bluetooth equipment is disconnected, the mobile phone judges whether the Bluetooth type of the disconnected Bluetooth equipment is classic Bluetooth or dual-mode Bluetooth or not and whether the equipment type is a preset equipment type or not; and if the Bluetooth type of the currently disconnected Bluetooth equipment is classic Bluetooth or dual-mode Bluetooth and the equipment type is the preset equipment type, registering the action monitoring service.

It is understood that the conditions of the registration action listening service are: the mobile phone and the Bluetooth device of which the Bluetooth type is classic Bluetooth or dual-mode Bluetooth and the device type is a preset device type disconnect the Bluetooth connection.

Therefore, in practical application, after the bluetooth connection is established between the mobile phone and the bluetooth device, it may be determined whether the bluetooth type of the bluetooth device currently establishing the bluetooth connection is classic bluetooth or dual-mode bluetooth, and whether the device type is a preset device type; if yes, monitoring the state change of the Bluetooth connection; after the current Bluetooth connection is monitored to be disconnected, the action monitoring service is started.

Based on the above understanding, after step S504 or S505, step S506 shown in fig. 8 and the following steps may also be performed:

s506, the mobile phone monitors the state change of the Bluetooth connection.

S507, the mobile phone monitors that the Bluetooth connection between the mobile phone and the Bluetooth device is disconnected.

And S508, after the mobile phone monitors that the Bluetooth connection between the mobile phone and the Bluetooth device is disconnected, registering the action monitoring service.

In the embodiment of the present application, since step S503 has been executed in the stage of storing the mac address, and it has been determined that the bluetooth type of the currently connected bluetooth device is the classic bluetooth or the dual-mode bluetooth, and the device type is the preset device type, in step S507, it may be no longer necessary to determine whether the bluetooth type of the bluetooth device currently disconnected from the bluetooth connection is the classic bluetooth or the dual-mode bluetooth, and whether the device type is the preset device type according to the manner of the embodiment shown in fig. 7; but directly performs step S508 to register the action listening service.

Of course, after step S508, steps S308 to S314 may be performed. The embodiment of the present application is not described in detail.

As described above, before the mobile phone sends back the connection request broadcast, the mobile phone determines the mac address carried in the connection request broadcast in such a manner that the mac address of the bluetooth device whose device type is the preset device type, bluetooth type is classic bluetooth or dual-mode bluetooth, and connection state is disconnected is searched from the stored mac address list. In practical applications, a broadcast may be sent to a plurality of backhaul requests respectively corresponding to mac addresses.

For example, after the bluetooth connection is established between the user's sports watch a and the user's mobile phone, the mac address of the sports watch a and other associated information are stored in the user's mobile phone. The user A gets out of the need for updating the sports watch, the sports watch A is eliminated (possibly left at home, or sent to the user or discarded), a new sports watch B is purchased and used, after the Bluetooth connection is established between the sports watch B of the user and the mobile phone of the user, the mac address of the sports watch B and other related information are stored in the mobile phone of the user.

When the user wears the sports watch B to go out and go back to home again to pick up the mobile phone, the mobile phone can trigger the broadcast of the Bluetooth connection request carrying the mac address of the sports watch A and the broadcast of the Bluetooth connection request carrying the mac address of the sports watch B. In practice, however, the user no longer uses the sports watch. The handset need not send a broadcast of the bluetooth connection request carrying the mac address of sports watch a.

In view of this, the present embodiment also provides a method for acquiring a mac address.

After monitoring that the Bluetooth connection between the mobile phone and the Bluetooth equipment is disconnected, the mobile phone records the mac address of the currently disconnected Bluetooth equipment in the second storage space; and when the mobile phone is determined to be lifted or turned over, acquiring the mac address recorded in the second storage space at the latest, and broadcasting the Bluetooth connection request by the mobile phone based on the mac address recorded at the latest.

For the sake of distinction, a previously stored mac address list may be stored in the first memory space and the recorded mac addresses of disconnected bluetooth devices may be stored in the second memory space.

In the method for performing bluetooth connection according to the embodiment shown in fig. 7 or fig. 8, the process goes to step S309, and a mac address list is obtained from the first storage space and a mac address meeting the requirement is searched.

In the bluetooth connection method provided according to the current embodiment, when a mac address recorded latest needs to be searched (the latest recorded device type is a preset device type, the bluetooth type is classic bluetooth or dual-mode bluetooth, and the connection state is a mac address of a disconnected bluetooth device), the latest stored mac address is obtained from the second storage space.

Of course, in practical applications, the second storage space may also limit the number of stored mac addresses. For example, only one mac address is stored, so that the loopback request carries the latest stored mac address.

The second storage space may also store a plurality of mac addresses, each mac address may generate a backhaul request (also referred to as a bluetooth connection request), and accordingly, may send a broadcast corresponding to the plurality of backhaul requests.

For a clearer understanding of the steps respectively performed by the mobile phone and the bluetooth device in the above embodiments, reference may be made to the timing diagram shown in fig. 9. The timing diagram may correspond to the flow diagram of the bluetooth connection method shown in fig. 7.

The module participating in the Bluetooth connection method in the mobile phone comprises the following modules: desktop card applications, bluetooth ConnectService, motionservice, and SensorsModule.

The desktop card application is used for displaying the motion data synchronized with the Bluetooth equipment.

The bluetooth connecticservice is responsible for bluetooth connections between the handset and other bluetooth devices.

The sensorsform module is used for monitoring the motion of the mobile phone. Such as lifting, flipping, etc.

The Bluetooth connection service is responsible for Bluetooth connection between the Bluetooth device and the mobile phone.

The upper layer application is used to synchronize the motion data to the cell phone side through bluetooth connecticservice.

How the mobile phone and the bluetooth device implement the bluetooth connection method provided by the embodiment of the present application through the above modules will be described below.

S604, the Bluetooth ConnectService in the mobile phone stores the mac address, the Bluetooth type and the device type of the Bluetooth device.

S605, the bluetooth connectivity service in the mobile phone registers the bluetooth connection state change monitoring service.

In practical applications, if the step S601 is a non-initial bluetooth connection between the mobile phone and the bluetooth device, the steps S602 to S604 are not executed, but the step S605 is executed.

S607, the bluetooth connectivity service in the mobile phone determines that the bluetooth type of the currently disconnected bluetooth device is a classic bluetooth or a dual-mode bluetooth, and the device type is a preset device type.

In practical application, after the bluetooth connectivity service in the bluetooth device monitors that the bluetooth connection is disconnected, an incremental periodic transmission connection request task is started. The incremental periodic transmission connection request task indicates that the bluetooth device will periodically transmit bluetooth connection requests, except that the period for transmitting bluetooth connection requests will gradually become longer.

S608, the bluetooth connecticservice in the mobile phone determines that the bluetooth type of the currently disconnected bluetooth device is the classic bluetooth or the dual-mode bluetooth, and when the device type is the preset type, the bluetooth connecticservice in the mobile phone registers an action monitoring service with the mobility service in the mobile phone.

S609, after the Motionservice in the mobile phone receives the information of the registration action monitoring service, the Motionservice sends the information of starting action identification and setting the event reporting mark as true to the SensorsModule in the mobile phone.

S610, a sensorModule in the mobile phone monitors the acceleration monitored by the acceleration sensor and the angular velocity monitored by the gyroscope.

S611, the SensorsModule in the mobile phone determines the current action of lifting or turning the mobile phone according to the monitored data, and the reported query event is marked as true.

S612, the SensorsModule in the mobile phone reports the action event to the Motionservice in the mobile phone.

S613, after receiving the reported action event, the mobilestarvice in the mobile phone sends a bluetooth connection trigger event to the bluetooth connecticservice in the mobile phone.

And S614, after the Bluetooth ConnectService in the mobile phone receives the Bluetooth loopback triggering event, searching the mac address of the Bluetooth device with the preset device type, the classical Bluetooth or the dual-mode Bluetooth type and the disconnected connection state from the mac address list.

S615, the bluetooth connectionservice in the mobile phone initiates a bluetooth connection request (or bluetooth connection request) broadcast based on the found mac address.

And S616, after the Bluetooth ConnectService in the Bluetooth equipment receives the Bluetooth return connection request broadcast, under the condition that the mac address carried in the Bluetooth return connection request is determined to be consistent with the mac address of the Bluetooth equipment, the Bluetooth connection with the mobile phone is recovered.
