[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0031] It should be noted that, in this article, the terms "include", "comprises" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "includes a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element. In addition, components, features, and elements with the same name in different embodiments of the present application may have the same meaning or different meanings, and their specific meanings need to be determined by their explanation in the specific embodiment or further combined with the context of the specific embodiment.

[0032] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0033] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application, and have no specific meanings. Therefore, "module", "component" or "unit" can be used in a mixed manner.

[0034] In the description of the present application, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, terms such as "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0035] In some Bluetooth usage scenarios, time slot reservation is important, but when there are multiple services or multiple connections on a device, the allocation of time slots between devices is not "uniformly scheduled". For example, one end of the device already has other services allocated to it in the negotiation area; or the time slots of broadcast services are completely determined by the master device, and it cannot participate in the negotiation mechanism; or there are multiple master devices, and they will each initiate services and cannot be uniformly negotiated because they are established one after another. In all of the above situations, there will be time slot conflicts, and neighboring nodes will not have aligned free time slots, resulting in the inability to establish a connection or synchronize broadcast information.

[0036] Based on this, the embodiments of the present application provide a Bluetooth service synchronization method, device, storage medium and electronic device, allowing high-priority node devices to pre-allocate synchronization alignment time slots. When there is a need to establish a connection or synchronize broadcast information in the node device, it can be allocated or created in the reserved alignment time slot.

[0037] The technical solutions shown in the present application will be described in detail below through specific embodiments. It should be noted that the description order of the following embodiments is not intended to limit the priority order of the embodiments.

[0038] See also Figure 1 , Figure 1 : is a flow chart of a Bluetooth service synchronization method provided in an embodiment of the present application. The specific flow of the Bluetooth service synchronization method may be as follows:

[0039] 101. When the first Bluetooth device creates a new service, it searches whether there is a created periodic beacon. The created periodic beacon is created first for other Bluetooth devices.

[0040] The periodic beacon is a signal used for communication between devices. It is broadcast periodically to ensure network synchronization and smooth device discovery. The periodic beacon can be in various forms such as periodic advertisement (PeriodicADV) and periodic audio beacon (BIS).

[0041] When the first Bluetooth device finds a created periodic beacon during the search process, by using the periodic beacons created by other Bluetooth devices, the first Bluetooth device can avoid time slot conflicts without coordination, thereby improving the collaboration efficiency between Bluetooth devices. In addition, the created periodic beacons have already arranged time slots and allocated resources, so the first Bluetooth device only needs to follow these periodic beacons, reducing the complexity of self-coordinating time slots and broadcasting. When the first Bluetooth device uses the created periodic beacon, it can quickly adapt according to the periodic beacons and business needs of other Bluetooth devices, thereby ensuring efficient communication between devices.

[0042] 102. If the created periodic beacon is not searched, create a target periodic beacon through the first Bluetooth device, and broadcast the target periodic beacon, so that other Bluetooth devices search for and find the target periodic beacon and create their own periodic beacons according to the target periodic beacon.

[0043] When the first Bluetooth device does not find the created periodic beacon during the search process, it means that there are no other Bluetooth devices around that have priority to create periodic beacons or these Bluetooth devices have not yet broadcast. In this case, the first Bluetooth device will start its own periodic beacon creation process, generate a target periodic beacon and broadcast it, so that other devices can synchronize to this periodic beacon and create their own periodic beacons. This process ensures that the first Bluetooth device can still coordinate time slots and allocate resources even if there are no other Bluetooth devices broadcasting periodic beacons.

[0044] The target periodic beacon may include the transmission time of the beacon data and the window duration of the reserved time slot. Specifically, other Bluetooth devices may create their own periodic beacons according to the transmission time of the beacon data and the window duration of the reserved time slot.

[0045] In some embodiments, after searching for the target periodic beacon, other Bluetooth devices can parse the sending time of the beacon data, calculate their own receiving time offset value, and synchronously adjust their own periodic beacons based on the receiving time offset value to align the start time of their time slots with the reserved time slots of the target periodic beacon, thereby ensuring that the time slots between multiple devices will not conflict and ensuring the smooth progress of subsequent communication or synchronization services.

[0046] It is understandable that when other Bluetooth devices receive the target periodic beacon, the signal propagation time may also be different due to the different distances between the devices. Therefore, the device can calculate the reception time offset value based on the transmission time of the beacon data and its own reception time. The reception time offset value refers to the time difference between the time when the device receives the target periodic beacon and the time when the target beacon is broadcast.

[0047] The receive time is the moment when the device actually receives the target period beacon, and the send time of the beacon data is the timestamp contained in the target period beacon. In this way, other Bluetooth devices can understand the difference between their own clocks and the time slot arrangement in the target period beacon.

[0048] After calculating the receive time offset value, other Bluetooth devices need to adjust their own periodic beacons. Since the target periodic beacon already contains the window duration of the reserved time slot, other Bluetooth devices can align their own periodic beacons based on the receive time offset value they calculated, so that their time slots are completely aligned with the time slots of the target periodic beacon. Time slot alignment means that other Bluetooth devices will adjust the start time of their own periodic beacons to coincide with the start time of the time slot of the target periodic beacon. In this way, the time slots of each device will be synchronized to avoid time slot conflicts caused by time differences.

[0049] It should be noted that when creating the target periodic beacon, the first Bluetooth device can set the window duration of the reservation time slot according to its business needs and network environment. In order to facilitate coordination between devices, the first Bluetooth device usually sets the window duration of the reservation time slot to an integer multiple of the basic period to ensure that the periodic beacons of all devices can be synchronized at the same time granularity, reducing time slot conflicts caused by inconsistent period settings.

[0050] In addition, the first Bluetooth device can dynamically adjust the size of the basic cycle according to its own business type and priority. For example, if the business load of the device is heavy, the first Bluetooth device can select a longer basic cycle to provide more sufficient time slot resources; if the business of the device is light, the first Bluetooth device can select a shorter basic cycle to save resources and improve network efficiency. By dynamically adjusting the size of the basic cycle, the first Bluetooth device can flexibly respond to different business needs and network environments. That is, by dynamically adjusting the size of the basic cycle, the first Bluetooth device can reasonably allocate time slots according to the priorities of different business types (such as data transmission, audio streaming, etc.), ensuring that high-priority businesses can obtain sufficient resources.

[0051] In some embodiments, the target periodic beacon may also include time slot allocation information of the periodic service of the first Bluetooth device, where the time slot allocation information is used to instruct other Bluetooth devices to avoid service time slot conflicts when creating their own periodic beacons.

[0052] 103. When a new connection or synchronous broadcast service needs to be established between the first Bluetooth device and other Bluetooth devices, time slots are allocated according to the periodic beacons created by each device.

[0053] In some embodiments, when the time slot demand for a new connection or synchronous broadcast service between the first Bluetooth device and other Bluetooth devices exceeds the window duration of the reserved time slot, the first Bluetooth device can preferentially release its occupied low-priority service time slot to meet new service demands.

[0054] In some embodiments, when the first Bluetooth device allocates a new connection or a synchronous broadcast service within the window duration of the reserved time slot, it may also include: detecting an idle time slot within the window duration of the reserved time slot; allocating the idle time slot to the new connection or the synchronous broadcast service; updating and broadcasting the target period beacon so that other Bluetooth devices adjust their own time slot allocation according to the updated target period beacon.

[0055] For example, in the actual application scenario of the smart home system, multiple Bluetooth devices need to frequently exchange and synchronize data. When a Bluetooth thermostat needs to establish a new connection with a Bluetooth light bulb to synchronize temperature information, it will allocate time slots according to the preset periodic beacon. If a new Bluetooth device, such as a smart door lock, needs to join the network and establish a connection at this time, and the current reservation time slot window length cannot meet the needs of the two devices to connect at the same time, then the Bluetooth thermostat will release low-priority time slots according to its business priority to ensure that high-priority businesses (such as secure connections to door locks) can proceed smoothly. In addition, after releasing the low-priority time slot, the Bluetooth thermostat will update its periodic beacon and notify other Bluetooth devices of this change through broadcasting. In this way, other devices such as Bluetooth light bulbs can adjust their own time slot allocations according to the new periodic beacon to avoid time slot conflicts and ensure the stable operation of the entire smart home system.

[0056] In summary, the Bluetooth service synchronization method provided by the embodiment of the present application includes searching whether there is a created periodic beacon when the first Bluetooth device creates a new service, and the created periodic beacon is created first for other Bluetooth devices; if the created periodic beacon is not searched, a target periodic beacon is created by the first Bluetooth device, and the target periodic beacon is broadcasted, so that other Bluetooth devices search and find the target periodic beacon and create their own periodic beacons according to the target periodic beacon; when a new connection or synchronous broadcast service is required between the first Bluetooth device and other Bluetooth devices, time slots are allocated according to the periodic beacons created by each Bluetooth device. In this solution, the periodic beacons created by each Bluetooth device are allocated time slots, thereby avoiding time slot conflicts between devices.

[0061] The allocation unit 203 is configured to allocate time slots according to periodic beacons created by each of the first Bluetooth device and other Bluetooth devices when a new connection or synchronous broadcast service is required between the first Bluetooth device and other Bluetooth devices.
