[0025] Bluetooth technology is a wireless communication technology that allows data transmission between different devices within a short distance. It has the characteristics of ease of use, flexibility and low power consumption.
[0026] In related technologies, in a single system or distributed system with Bluetooth communication capabilities, the Bluetooth protocol stack and upper-layer applications are bound to specific Bluetooth hardware. During the entire process of connecting and communicating with the communication peer device, the communication quality is affected by factors such as the distance, direction, and environment between the two devices.
[0027] To address the above technical issues, embodiments of the present disclosure provide a Bluetooth communication method, apparatus, electronic device, storage medium, and program product. These methods determine a target terminal corresponding to a source terminal and, based on communication quality parameters between the candidate Bluetooth controllers and the target terminal, determine a target Bluetooth controller from multiple candidate Bluetooth controllers. Communication data is then transmitted to the target terminal via the target Bluetooth controller. The binding relationship can be dynamically switched based on the communication quality parameters between the candidate Bluetooth controllers and the target terminal, thereby improving the quality of Bluetooth communication with the target device.
[0028] Figure 1 is a schematic block diagram of an application scenario of a Bluetooth communication method according to an exemplary embodiment. Figure 1 As shown, it may include a manager, multiple applications and multiple Bluetooth controllers, wherein the manager may be a Bluetooth communication device, which may include multiple Bluetooth protocols and positioning management modules, multiple Bluetooth protocol stacks and a positioning device.
[0029] Among them, multiple Bluetooth controllers can be deployed in a single system or multiple subsystems of a distributed system, including Bluetooth control-related hardware, firmware, radio frequency devices, etc., and communicate with the system deploying the Bluetooth protocol stack through the standard HCI (Host Controller Interface).
[0030] Among them, multiple Bluetooth protocol stacks are deployed in a single system or a central or hub system in a distributed system. Each Bluetooth protocol stack is connected to the HCI standard interface of the system and the Bluetooth controller to communicate with a specific Bluetooth controller and jointly implement the Bluetooth communication protocol.
[0031] Among them, multiple Bluetooth protocol stacks and positioning management modules are deployed in a single system or a central or hub system in a distributed system to manage multiple Bluetooth protocol stacks and provide Bluetooth communication services to multiple upper-layer applications; the multiple Bluetooth protocol stacks and positioning management modules use Bluetooth and other positioning device capabilities to determine the relative position relationship of multiple devices connected to each Bluetooth controller, and dynamically switch the binding relationship according to the position relationship between each device and each Bluetooth controller, to ensure that the device communicates with the Bluetooth controller closest to it, and to ensure the optimal communication quality.
[0032] Each application uses Bluetooth communication capabilities through multiple Bluetooth protocol stacks and positioning management modules, without having to worry about the connection relationship between the peer device and the Bluetooth controller.
[0033] Figure 2 FIG. 1 is a flow chart showing a Bluetooth communication method according to an exemplary embodiment. Figure 2 As shown, it can be applied to the manager and may include the following steps.
[0034] In step S201, a target terminal corresponding to a source terminal is determined.
[0035] In this embodiment, a user can establish a Bluetooth connection with a target terminal based on an application on a source terminal and through a manager and a Bluetooth controller, thereby enabling data transmission between the source terminal and the target terminal, wherein the manager can be a Bluetooth communication device. During data transmission, the source terminal can first transmit the target communication data to be transmitted to the Bluetooth communication device, and the Bluetooth communication device then transmits the target communication data to the target terminal through the corresponding Bluetooth controller. After receiving the target communication data, the Bluetooth communication device can determine the target terminal corresponding to the target communication data. Specifically, the target communication data can carry a terminal identifier, which includes the terminal identifier of the source terminal and the terminal identifier of the target terminal. The target terminal can be determined by the terminal identifier of the target terminal. Alternatively, before data transmission, the source terminal can send the terminal identifier of the target terminal to the Bluetooth communication device so that the Bluetooth communication device can determine the target terminal.
[0036] In step S202, a target Bluetooth controller is determined from a plurality of candidate Bluetooth controllers according to the communication quality parameters between the candidate Bluetooth controllers and the target terminal.
[0037] In this embodiment, the Bluetooth communication device can be connected to multiple candidate Bluetooth controllers. Each candidate Bluetooth controller is connected to the Bluetooth communication device via a Bluetooth protocol stack. The multiple candidate Bluetooth controllers are located in different locations. The target terminal can be a fixed terminal or a mobile terminal. The target Bluetooth controller can be determined based on communication quality parameters between the candidate Bluetooth controllers and the target terminal. For example, the candidate Bluetooth controller with the best communication quality with the target terminal can be determined as the target Bluetooth controller.
[0038] In step S203, data transmission between the source terminal and the target terminal is implemented through the target Bluetooth controller.
[0039] In this embodiment, after determining the target Bluetooth controller, the Bluetooth communication device can realize data transmission between the source terminal and the target terminal through the target Bluetooth controller. For example, the target communication data sent by the source terminal can be transmitted to the target terminal through the target Bluetooth controller, thereby realizing data transmission between the source terminal and the target terminal.
[0040] In this embodiment, the binding relationship can be dynamically switched according to the communication quality parameters between multiple candidate Bluetooth controllers and the target terminal. During each data transmission process, the target Bluetooth controller with the best communication quality with the target terminal can be used to transmit data, so as to improve the communication quality of Bluetooth communication with the target device.
[0041] In a possible implementation manner, the communication quality parameter includes a communication distance.
[0042] According to the communication quality parameters between the candidate Bluetooth controllers and the target terminal, the method for determining the target Bluetooth controller from multiple candidate Bluetooth controllers may be: Determine the communication distance between each of the multiple candidate Bluetooth controllers and the target terminal; and determine the target Bluetooth controller from the multiple candidate Bluetooth controllers based on the communication distance.
[0043] In this embodiment, the communication quality parameter may include a communication distance, and the communication quality may be determined based on the communication distance. Specifically, the communication quality may be negatively correlated with the communication distance. The communication distance between each candidate Bluetooth controller and the target terminal may be determined separately, and then the candidate Bluetooth controller with the shortest communication distance to the target terminal among the multiple candidate Bluetooth controllers may be determined as the target Bluetooth controller to ensure optimal Bluetooth communication quality.
[0044] In a possible implementation, a method for determining the communication distance between each of the multiple candidate Bluetooth controllers and the target terminal may be: Determine a target location of the target terminal; and determine a communication distance between each candidate Bluetooth controller and the target terminal based on the target location of the target terminal and the location of each candidate Bluetooth controller among a plurality of candidate Bluetooth controllers.
[0045] In this embodiment, the target location of the target terminal can be determined first, and the target location can include location coordinates. Each candidate Bluetooth controller is set at a different and fixed location, and the location coordinates of each candidate Bluetooth controller can be directly obtained, thereby determining the communication distance between each candidate Bluetooth controller and the target terminal based on the location coordinates of each Bluetooth controller and the location coordinates of the target terminal. Specifically, for any candidate Bluetooth controller, the straight-line distance between the two coordinates can be directly calculated based on the location coordinates of the candidate Bluetooth controller and the location coordinates of the target terminal to obtain the communication distance between the candidate Bluetooth controller and the target terminal.
[0046] In a possible implementation, a method for determining the target location of the target terminal may be: A plurality of target images including a target terminal are acquired through a camera; image recognition is performed on the plurality of target images to obtain a target position of the target terminal.
[0047] In this embodiment, the Bluetooth communication device may include a positioning device, which may be multiple cameras. The positioning device may detect the target terminal based on multiple cameras at different locations to obtain multiple target images including the target terminal. Image recognition may then be performed on the multiple target images to identify the location of the target terminal in the target images and obtain the target location.
[0048] In a possible implementation, a method for determining the target location of the target terminal may be: The round trip time of positioning signals between the plurality of positioning devices and the target terminal is determined; and the target position of the target terminal is determined based on the round trip time.
[0049] In this embodiment, multiple positioning devices can each send positioning signals to a target terminal and receive return positioning signals from the target terminal, thereby determining the round-trip time of the positioning signals between the multiple positioning devices and the target terminal. The target terminal's target location is then determined based on the round-trip time of the positioning signals between each positioning device and the target terminal, combined with the position coordinates of the positioning devices.
[0050] In a possible implementation, a method for determining the target location of the target terminal may be: Determine the time difference between multiple base stations receiving the pulse signal sent by the target terminal; and determine the target position of the target terminal based on the time difference.
[0051] In this embodiment, the positioning device may include multiple base stations, the target terminal may send a pulse signal, and the multiple base stations may receive the pulse signal sent by the target terminal and determine the time when each base station receives the pulse signal, thereby determining the time difference between the multiple base stations receiving the pulse signal sent by the target terminal based on the time when each base station receives the pulse signal, so as to determine the target position of the target terminal based on the time difference.
[0052] In a possible implementation, the communication quality parameter further includes Bluetooth communication strength. The method further includes: Determine the Bluetooth communication strength between each candidate Bluetooth controller among the plurality of candidate Bluetooth controllers and the target terminal.
[0053] In this embodiment, the Bluetooth communication strength between each candidate Bluetooth controller and the target terminal may be determined. The Bluetooth communication strength may be directly determined according to the signal strength of the target terminal detected by the candidate Bluetooth controller.
[0054] After obtaining the Bluetooth communication strength between each candidate Bluetooth controller and the target terminal, a method for determining a target Bluetooth controller from multiple candidate Bluetooth controllers based on the communication distance may be: A target Bluetooth controller is determined from multiple candidate Bluetooth controllers according to the communication distance and the Bluetooth communication strength.
[0055] In this embodiment, the communication quality between each candidate Bluetooth controller and the target terminal can be determined in combination with the communication distance and the Bluetooth communication strength. Specifically, the communication quality is negatively correlated with the communication distance, and the communication quality is positively correlated with the Bluetooth communication strength. For any candidate Bluetooth controller, a first coefficient corresponding to the communication distance between the candidate Bluetooth controller and the target terminal, and a second coefficient corresponding to the Bluetooth communication strength between the candidate Bluetooth controller and the target terminal can be determined. Among them, the first coefficient is inversely proportional to the communication data, and the second coefficient is inversely proportional to the Bluetooth communication strength. The communication quality score corresponding to the Bluetooth controller can be obtained based on the product of the communication distance between the candidate Bluetooth controller and the target terminal and the corresponding first coefficient, and the product of the Bluetooth communication strength between the candidate Bluetooth controller and the target terminal and the second coefficient, so as to determine the communication quality according to the communication quality score. Among them, the communication quality score is positively correlated with the communication quality, and the candidate Bluetooth controller with the largest communication quality score among multiple candidate Bluetooth controllers can be determined as the target Bluetooth controller.
[0056] In a possible implementation, the communication quality parameter includes Bluetooth communication strength.
[0057] According to the communication quality parameters between the candidate Bluetooth controllers and the target terminal, the method for determining the target Bluetooth controller from multiple candidate Bluetooth controllers may be: Determine the Bluetooth communication strength between each candidate Bluetooth controller among the multiple candidate Bluetooth controllers and the target terminal; and determine a target Bluetooth controller from the multiple candidate Bluetooth controllers based on the Bluetooth communication strength.
[0058] In this embodiment, the candidate Bluetooth controller with the strongest Bluetooth communication strength may be directly determined as the target Bluetooth controller.
