Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
The technical scheme is suitable for a Bluetooth connection scene, particularly suitable for a scene that BLE communication is carried out between a master Bluetooth device and a slave Bluetooth device in the Bluetooth connection scene, wherein the master Bluetooth device is the Bluetooth device which searches and actively establishes connection in the Bluetooth connection scene, and the master Bluetooth device can search surrounding Bluetooth devices and select the Bluetooth devices which need to be connected to pair and connect; the slave bluetooth device refers to a device waiting to be searched for a connection by the master bluetooth device in a bluetooth connection scenario. Specifically, the main bluetooth device may be a mobile phone, a notebook computer, etc.; the slave bluetooth device may be a headset, a smart stereo, etc., for example, the slave bluetooth device may be a TWS headset, which is an abbreviation for "True Wireless Stereo" headset, meaning a true wireless stereo headset. This type of earphone is a wireless audio device that does not require a conventional connection wire nor a cable that connects to a cell phone, music player or other device. In contrast, the TWS headset realizes connection between the left and right two headsets through the bluetooth technology, and communicates with the audio source device. TWS headphones typically consist of two separate headphone units, each containing one speaker and one battery. The two headphones may be connected to the audio source device at the same time and play music or other sounds in stereo mode. The user can put them into the ear without any connecting wires, so they are called "true wireless". The present application is not limited. It should be appreciated that a bluetooth device may either initiate a communication connection as a master bluetooth device or receive a communication connection as a slave bluetooth device; one bluetooth device can also serve as a master bluetooth device and a slave bluetooth device at the same time.
The technical solution of the present application may be applied to a bluetooth system composed of a master bluetooth device and a slave bluetooth device, as shown in fig. 1A, where the bluetooth system 10 may include a slave bluetooth device 101 and a master bluetooth device 102, where the master bluetooth device may include a plurality of master bluetooth devices (E1, E2 …, en), n is the number of master bluetooth devices, and n may theoretically be any integer greater than 0.
In the bluetooth system 10, there may be multiple communication channels between the slave bluetooth device 101 and the master bluetooth device 102, such as a classical bluetooth channel established by classical bluetooth and a bluetooth low energy channel established by BLE, and when connected together, the master bluetooth device 102 may establish a BLE connection and a classical bluetooth connection with the slave bluetooth device 101 at the same time to meet different communication requirements. For example, BLE connections may be used for low power, low latency audio transmissions, while classical bluetooth connections may be used for high quality audio transmissions and other data transmissions. The double-channel operation mode enables the mobile phone and the earphone to realize flexible communication under different scenes. Wherein BLE communication channels are generally divided into broadcast channels and data communication channels. The slave bluetooth device 101 may broadcast its own presence and basic information, i.e. the connection parameters in this scheme, before connection using the BLE broadcast channel. The master bluetooth device 102 may listen to the broadcast channel to discover nearby slave bluetooth devices 101 and obtain device information, which may be transmitted bi-directionally over the BLE data communication channel once a BLE connection is established between the slave bluetooth devices 101 and the master bluetooth device 102. This is typically used to transmit control commands, device status information, etc.
It should be understood that the slave bluetooth device and the master bluetooth device in the bluetooth connection system may not be limited to the above-described case, but may be more cases, and the present application is not limited thereto.
Based on the bluetooth system shown in fig. 1A, the technical solution of the present application may be implemented, where the technical solution of the present application is specifically applied to a bluetooth system 10, where the bluetooth system 10 is composed of a master bluetooth device and a slave bluetooth device, and fig. 1B may be referred to, and fig. B is a schematic flow diagram of an interaction process in the bluetooth system provided in the embodiment of the present application, where the method includes the following steps:
s101, acquiring current connection parameters from Bluetooth equipment, determining target broadcast data according to the connection parameters, wherein the target broadcast data is sent by the Bluetooth equipment through broadcasting and received by main Bluetooth equipment, and the target broadcast data comprises connection interval parameters which are used for appointing BLE communication intervals after the BLE connection between the main Bluetooth equipment and the Bluetooth equipment is established.
S102, the target broadcast data is sent from the Bluetooth device to the master Bluetooth device.
S103, the main Bluetooth device receives the target broadcast data.
S104, the main Bluetooth device analyzes the target broadcast data to obtain the connection interval parameters.
S105, the master Bluetooth device sends a connection request to the slave Bluetooth device.
S106, the slave Bluetooth device receives a connection request sent by the master Bluetooth device.
And S107, the slave Bluetooth device establishes BLE data communication connection with the master Bluetooth device according to the connection interval parameter in the target broadcast data.
Through the interaction process, in the case that the master bluetooth device and the slave bluetooth device are not in communication, that is, the ideal connection interval parameter of the slave bluetooth device cannot be obtained, the connection interval parameter when the slave bluetooth device establishes BLE connection with the master bluetooth device is determined, and the communication connection between the master bluetooth device and the slave bluetooth device is established according to the connection interval parameter without bandwidth occupation conflict, that is, under the condition that normal BLE communication is ensured, other bluetooth links which are connected with the slave bluetooth device still have enough bandwidth use.
Based on the bluetooth system shown in fig. 1A, the technical scheme of the application can be implemented, wherein the technical scheme of the application is specifically applied to a slave bluetooth device in the bluetooth system, and the slave bluetooth device is in communication connection with a master bluetooth device.
The following specifically describes the technical scheme of the present application.
Referring to fig. 2, fig. 2 is a schematic flow chart of a bluetooth connection method provided in an embodiment of the present application, where the method may be applied to a bluetooth system, and the bluetooth system may be as shown in fig. 1A. As shown in fig. 2, the method comprises the steps of:
s201, acquiring current connection parameters from the Bluetooth device.
The connection parameters of the slave bluetooth device refer to a plurality of parameters related to bluetooth connection, the connection parameters determine performance and behavior of the bluetooth connection, and the connection parameters are used for evaluating stability, transmission rate, response time of the connection and optimizing when the number of connections increases, the device is in a low-delay mode or the power is low.
The connection parameters of the slave bluetooth device may include, but are not limited to, the number of connections with other bluetooth devices in the slave bluetooth device, or the slave bluetooth device is in a low-latency mode, or the power of the slave bluetooth device.
The connection parameters of the slave bluetooth device can be obtained through the API or the instruction of the bluetooth chip, and the specific operation mode depends on the model and manufacturer of the bluetooth chip.
In particular, if the number of connections is known among the number of connections with other bluetooth devices in the slave bluetooth device, it can help the slave bluetooth device decide whether or not to optimize connection management, such as allocating resources when multiple connections exist, limiting the number of connections, or providing higher bandwidth, etc.; if the slave Bluetooth device is in the low-delay mode, the mode indicates whether the slave Bluetooth device is currently in the low-delay audio transmission mode. If real-time audio transmission (e.g., music playing or talking) is desired from the bluetooth device, the low latency mode may be enabled to reduce the delay of the audio transmission. Knowing whether the slave bluetooth device is in a low latency mode can affect the configuration of the connection parameters to meet the requirements of low latency audio transmission; if the slave Bluetooth device is powered, the battery power level of the slave Bluetooth device is represented. Knowing the battery level may help the device decide whether or not to adjust the connection parameters to extend battery life. When the power is low, measures may be taken to reduce the frequency of bluetooth communications or increase the connection interval, thereby reducing power consumption.
It can be seen that the adjustment of the connection parameters depends on the current state of the slave bluetooth device and the connection requirements. By monitoring the connection quantity, the low-delay mode and the electric quantity state of the main Bluetooth device, the connection parameters can be flexibly configured so as to meet different application scenes and performance requirements. This allows optimizing the stability, performance and energy consumption of the connection.
S202, determining target broadcast data according to the connection parameters, wherein the target broadcast data is sent by the slave Bluetooth device through broadcasting and is received by the master Bluetooth device, and the target broadcast data comprises connection interval parameters which are used for appointing BLE communication intervals after the master Bluetooth device is connected with the slave Bluetooth device BLE.
Wherein the broadcast data refers to data for broadcasting, the broadcast data containing information for identifying and describing broadcasting devices, comprising: the broadcast data flag (Advertising Flags) is used to describe the function and status of the broadcast device. For example, it may indicate whether the device supports BLE connection, whether low power mode is supported, whether it is in a connectable state, etc.; local device Name (Local Name): for identifying devices, for example, when you search for bluetooth devices on a cell phone, you see the names of nearby devices. The local device name is typically user defined for easy identification of the device; the service UUID (Service UUID) this field contains one or more UUID (Universally Unique Identifier) for identifying BLE services supported by the device, from which the master bluetooth device can determine whether to establish a connection with the broadcasting device and further learn about the services provided by the device; connection interval parameters in broadcast packets: in some cases, the broadcast data may include parameters related to the BLE connection, such as connection interval parameters, which are typically used to tell other devices how to establish a connection or communicate; other optional fields: the broadcast data may also contain other optional information such as battery power of the device, temperature sensor data, etc., depending on the application and design of the device. Other data are not listed.
Wherein broadcasting is a passive communication mode, and the slave bluetooth devices periodically broadcast the data so that nearby master bluetooth devices can receive the data, and the master bluetooth devices can decide whether to establish a connection with a specific device according to information contained in the broadcast data.
The connection interval parameter is used for telling the communication time interval which should be used after the BLE connection is established between the master Bluetooth device and the slave Bluetooth device.
It can be seen that communicating the connection interval parameter from the slave bluetooth device to the master bluetooth device via broadcast data helps ensure that the BLE connection established between the master bluetooth device and the slave bluetooth device has proper performance and stability to meet the communication requirements.
And S203, the target broadcast data is sent to the main Bluetooth device.
Before the target broadcast data is sent, the target broadcast data may be packaged into a broadcast data packet, and then the broadcast data packet is sent to the master bluetooth device.
Wherein the transmission may be periodically transmitted by the slave bluetooth device using a BLE broadcast channel, and the broadcast data packets are transmitted over BLE broadcast frames, which are transmitted during a particular broadcast interval.
It can be seen that before the BLE connection is established, the slave bluetooth device will send the target broadcast data to the master bluetooth device, and this procedure is to let the master bluetooth device know the existence, service and connection parameters of the slave bluetooth device, and based thereon decide whether to establish the BLE connection and how to configure the connection, so that the BLE communication is very convenient and adaptive through the discovery and connection procedure of the broadcast communication.
S204, receiving a connection request sent from the main Bluetooth device, and establishing BLE data communication connection with the main Bluetooth device according to the connection interval parameter in the target broadcast data.
The slave Bluetooth device monitors the connection request on the broadcast channel, and once the slave Bluetooth device receives the connection request of the master Bluetooth device, the slave Bluetooth device analyzes the request to acquire the connection parameter request, particularly the connection interval parameter, contained in the request.
Specifically, after receiving a connection establishment request, the slave bluetooth device responds to the request and configures connection according to a connection interval parameter in the request, wherein the connection interval parameter ensures that the performance and the power consumption of the connection meet the requirements. When the BLE connection is established, two-way BLE data communication may commence between the master bluetooth device and the slave bluetooth device, which may include transmission control commands, audio data, sensor data, or other types of information.
After the connection of the BLE data communication is established successfully, continuously monitoring the connection parameters of the slave bluetooth device, and if the connection parameters change after connection, updating the connection interval parameters of the BLE data communication to update the connection interval information on the BLE data channel according to the new connection interval parameters.
The connection interval parameter in the target broadcast data defines the frequency of communication between the master bluetooth device and the slave bluetooth device after connection, namely, the connection interval parameter refers to the time interval of data communication after connection, the shorter connection interval parameter can increase the frequency of data communication and further increase the energy consumption, and conversely, the longer connection interval parameter can reduce the frequency of data communication and further reduce the energy consumption, thereby being beneficial to prolonging the battery life of the device. Thus, by adjusting the connection interval parameter, a balance can be found between battery life and communication frequency.
Further, the connection interval parameter in the target broadcast data also affects the communication response time between the bluetooth device and the surrounding devices. Shorter intervals will allow the broadcaster to respond to communication requests faster, suitable for applications requiring low latency, such as real sensor data or audio transmissions. Longer intervals may result in longer response times, but may reduce power consumption. Shorter connection intervals may improve the stability of communications between devices because they exchange information more frequently. This is important for applications requiring highly reliable communication. Longer connection intervals may increase the risk of packet loss of the communication, thereby reducing the stability of the communication.
In general, the connection interval parameter when the BLE connection is established with the master Bluetooth device is determined through the connection parameter of the slave Bluetooth device, so that the problem that a reasonable connection interval parameter is set according to the connection parameter of the slave Bluetooth device under the condition that the master Bluetooth device and the slave Bluetooth device are not in communication is solved, a reasonable BLE channel can be established, the bandwidth occupation conflict between the BLE device and other Bluetooth devices after the BLE connection is established is effectively reduced, and the communication link between the BLE device and the other Bluetooth devices is ensured to still have enough bandwidth use.
In an embodiment, the connection parameter is a first connection parameter, the first connection parameter includes a first connection number and a first mode, and determining the target broadcast data according to the connection parameter includes: acquiring a first connection number, wherein the first connection number is the connection number between the slave Bluetooth device and other Bluetooth devices; determining whether a first mode is adopted, wherein the first mode is that the slave Bluetooth equipment is in a low-delay mode; when the first connection number is greater than the preset connection number and in the first mode, determining first target broadcast data, wherein the first target broadcast data comprises first connection interval parameters, and the first connection interval parameters are greater than the preset connection interval parameters.
Wherein the first connection number refers to the number of bluetooth devices connected from the bluetooth devices, and the number may be 1, 2, etc., which is not limited only herein. And the connection status of the slave bluetooth device can be evaluated by the first connection number.
In particular, the acquisition of the first number of connections and the determination of whether the first mode is the first mode may be acquired from an API or instruction of the bluetooth chip of the bluetooth device, the specific manner of operation depending on the model and manufacturer of the bluetooth chip.
The low-delay mode is a communication mode between the bluetooth device and other bluetooth devices, and refers to a mode in which an interval time from transmission to reception is shortened.
The number of preset connections may be defined by the development of technology, and in this embodiment, the number of preset connections may be 2.
The preset connection interval parameter refers to a connection interval set when the bluetooth device leaves the factory, and may be determined by its own hardware, for example, may be 30 ms, 50 ms, etc., which is not limited only herein.
In the case where the first connection interval parameter is greater than the preset connection interval parameter, the first connection interval parameter is set to be greater than the preset connection interval parameter, and there is no limitation in scope, for example, if the preset connection interval parameter is 30 ms, the first connection interval parameter may be 31 ms, 40 ms, 50 ms, etc., which is not limited only herein.
Wherein the connection interval parameter defines the time interval between two connection packets, a shorter connection interval will result in more frequent communication interactions, while a longer interval will reduce the frequency of communication interactions.
Specifically, when the slave bluetooth device detects that bluetooth communication connection is established between the slave bluetooth device and 2 bluetooth devices, and the slave bluetooth device itself has started a low-latency mode, the first connection interval parameter is set to be 100 ms, i.e. the connection interval parameter is set to be larger than the preset connection interval parameter, so that the communication frequency between the master bluetooth device and the slave bluetooth device can be reduced, the electric quantity of the slave bluetooth device is saved, the power consumption is reduced, the service time is prolonged, the bandwidth occupying other bluetooth channels in the low-latency mode can be reduced, and normal communication with other bluetooth devices is ensured.
Therefore, when the slave Bluetooth device meets the first connection quantity requirement and the first mode, the connection interval parameter can be adjusted in the broadcasting stage, so that after BLE connection is established, the communication frequency between the master Bluetooth device and the slave Bluetooth device can be reduced, the electric quantity of the slave Bluetooth device is saved, the power consumption is reduced, the service time is prolonged, the bandwidth occupying other Bluetooth channels can be reduced, and the normal communication of other Bluetooth devices is ensured.
In an embodiment, after the determining whether the first mode is the low latency mode of the slave bluetooth device, the method further includes: and when the first connection number is smaller than the preset connection number or not in the first mode, determining second target broadcast data, wherein the second target broadcast data comprises second connection interval parameters, and the second connection interval parameters are smaller than the preset connection interval parameters.
When the slave Bluetooth device detects that the Bluetooth communication connection is not established between the slave Bluetooth device and 2 or more Bluetooth devices, and the slave Bluetooth device does not start a low-delay mode, the slave Bluetooth device is in a standby or low-power mode currently, and waits for a further connection request or a communication triggering event.
In the case where the second connection interval parameter is smaller than the preset connection interval parameter, the second connection interval parameter is set to be smaller than the preset connection interval parameter, and there is no limitation in scope, for example, if the preset connection interval parameter is 30 ms, the first connection interval parameter may be 20 ms, 25 ms, 10 ms, etc., which is not limited only herein.
It can be seen that decreasing the connection interval parameter may cause the BLE device to increase the frequency of data communication, thereby improving the real-time performance of the user operating on the main device, and the frequency of communication between devices is more frequent, so that the user can begin to exchange or operate data more quickly.
In an embodiment, the connection parameter is a second connection parameter, the second connection parameter is an electric quantity of the slave bluetooth device, and determining the target broadcast data according to the connection parameter includes: acquiring a second connection parameter; and if the second connection parameter is smaller than the preset slave Bluetooth equipment electric quantity, determining third target broadcast data, wherein the third target broadcast comprises a third connection interval parameter, and the third connection interval parameter is larger than the preset connection interval parameter.
The slave bluetooth device power is obtained through an API or an instruction of a bluetooth chip of the slave bluetooth device, and the specific operation mode depends on the model and manufacturer of the bluetooth chip.
The preset slave bluetooth device power may be set to 40%, which is not limited herein.
If the second connection parameter is smaller than the preset slave bluetooth device power, the current slave bluetooth device power is insufficient, if the second connection parameter is connected according to the preset connection interval, the power is lost rapidly due to frequent communication.
In the case where the third connection interval parameter is greater than the preset connection interval parameter, the third connection interval parameter is set to be greater than the preset connection interval parameter, and there is no limitation in scope, for example, if the preset connection interval parameter is 30 ms, the third connection interval parameter may be 31 ms, 40 ms, 50 ms, etc., which is not limited only herein.
It can be seen that by increasing the connection interval parameter, the bluetooth device can reduce the frequency of communication, thereby reducing the power consumption. This helps to extend the battery life of the device, and this energy saving measure is particularly important, especially when the power is low, to ensure that the device is still usable when needed.
In an embodiment, after the obtaining the second connection parameter, the method further comprises: and if the second connection parameter is larger than the preset slave Bluetooth equipment electric quantity, determining fourth target broadcast data, wherein the fourth target broadcast data comprises fourth connection interval parameters, and the fourth connection interval parameters are smaller than the preset connection interval parameters.
If the second connection parameter is larger than the preset slave bluetooth equipment electric quantity, the current slave bluetooth equipment electric quantity is sufficient, and energy-saving setting is not needed.
In the case where the fourth connection interval parameter is smaller than the preset connection interval parameter, the fourth connection interval parameter is set to be smaller than the preset connection interval parameter, and there is no limitation in scope, for example, if the preset connection interval parameter is 30 ms, the fourth connection interval parameter may be 20 ms, 25 ms, 10 ms, etc., which is not limited only herein.
Therefore, when the electric quantity of the slave Bluetooth device is sufficient, the frequency of data communication is increased by reducing the connection interval parameter, so that the real-time performance of the operation of the user on the master device is improved, the frequency of communication between the devices is more frequent, and the user can start data exchange or operation more quickly.
In an embodiment, after the receiving the connection request sent from the master bluetooth device and establishing a BLE data communication connection with the master bluetooth device according to the connection interval parameter in the target broadcast data, the method further includes: continuously acquiring a third connection parameter, wherein the third connection parameter is the connection parameter of the slave Bluetooth device after BLE communication is established; if the third connection parameter is different from the connection parameter corresponding to the target broadcast data, determining a target connection interval parameter according to the third connection parameter; transmitting the target connection interval parameter to the master Bluetooth device; and receiving a target connection parameter sent from the main Bluetooth device, wherein the target connection parameter comprises the target connection interval parameter and a start update time, and updating the connection interval parameter of the BLE data communication connection according to the target connection parameter.
The third connection parameter includes a first connection parameter and a second connection parameter, that is, after connection, information such as an electric quantity, a low power consumption mode, and the number of connections of the slave bluetooth device is continuously monitored.
If the third connection parameter varies, it is further determined that the connection interval parameter required by the bluetooth device at this time does not match the target broadcast data, and at this time, the content of the connection parameter in the data channel is adjusted according to the real-time device state and performance requirement, so as to optimize BLE communication.
Furthermore, the target connection interval parameter can be determined according to the adjustment modes respectively corresponding to the first connection parameter and the second connection parameter, and the connection interval parameter of the BLE data communication connection is updated according to the target connection interval parameter and the start update time, so that the instantaneity of the connection parameter is ensured, and the communication performance is optimized.
The target connection parameter is sent by a master Bluetooth device, when the master Bluetooth device establishes BLE connection with a slave Bluetooth device, and when the self connection parameter of the slave Bluetooth device is determined to change, the master Bluetooth device can actively send a new connection interval parameter to the master Bluetooth device, after receiving, the master Bluetooth device can set a start update time, package the connection interval parameter between the two synchronous devices and the start update time into the target connection parameter and send the target connection parameter to the slave Bluetooth device, and when the start update time arrives, the connection interval parameter of the BLE data communication connection is synchronously updated between the two devices.
It can be seen that the state of the slave bluetooth device is continuously detected after the BLE connection is established, and the connection interval parameter between data communications is updated in time to meet specific communication requirements. This helps to improve the real-time nature of the communication, ensuring that the device can respond quickly under different conditions.
Based on the bluetooth system shown in fig. 1A, the technical scheme of the application can be realized, wherein the technical scheme of the application is specifically applied to a master bluetooth device, and the master bluetooth device is in communication connection with a slave bluetooth device.
The following specifically describes the technical scheme of the present application.
Referring to fig. 3, fig. 3 is a schematic flow chart of a bluetooth connection method provided in an embodiment of the present application, where the method may be applied to a bluetooth system, and the bluetooth system may be as shown in fig. 1A. As shown in fig. 2, the method comprises the steps of:
s301, receiving target broadcast data, wherein the target broadcast data is sent by the slave Bluetooth device through broadcasting and received by the master Bluetooth device, and the target broadcast data comprises a connection interval parameter, wherein the connection interval parameter is used for appointing BLE communication interval after the master Bluetooth device is connected with the slave Bluetooth device BLE.
S302, analyzing the target broadcast data to obtain the connection interval parameters.
S303, sending a connection request to the slave Bluetooth device, and establishing BLE communication connection with the slave Bluetooth device according to the connection interval parameter in the target broadcast data.
Specifically, the master bluetooth device first initiates a scanning operation to listen to the broadcast channel and discover nearby BLE devices, including the target slave bluetooth device; when the master Bluetooth device scans broadcast data sent by the target slave Bluetooth device, the master Bluetooth device receives the broadcast data packets; the main Bluetooth device analyzes the received broadcast data packet to acquire information about the target device, including connection interval parameters; the process of parsing broadcast data generally includes the steps of: identifying a field in the broadcast data packet containing a connection interval parameter; typically, the connection interval parameter will be encoded in a specific manner and contained at a specific location of the broadcast data; extracting a value of a connection interval parameter, typically in milliseconds, representing a time interval between two BLE communications; once the master bluetooth device successfully parses the connection interval parameter, it can use this parameter to establish a BLE connection; the connection interval parameter tells the communication time interval which should be used after the BLE connection is established between the main Bluetooth device and the target device; the master bluetooth device may negotiate and establish a BLE data communication connection using the parsed connection interval parameters, as well as other connection parameters.
It can be seen that both the performance and stability of the connection can be ensured to meet the requirements. Once the BLE connection is established, bi-directional BLE data communication may begin between the master bluetooth device and the target device, with configuration of connection interval parameters helping to determine the rate and stability of data transmission.
In general, the implementation can further reduce the bandwidth occupation conflict between BLE and other Bluetooth devices after BLE connection is established by receiving the connection interval parameter sent by the slave Bluetooth device under the condition that the master Bluetooth device and the slave Bluetooth device are not in communication, namely, the ideal connection interval parameter of the slave Bluetooth device cannot be obtained, so that the other Bluetooth devices still have enough bandwidth use.
In an embodiment, the method further comprises: receiving a target connection interval parameter, wherein the target connection interval parameter is data sent when the slave Bluetooth equipment detects that the connection parameter of the slave Bluetooth equipment changes after BLE communication is established; transmitting target connection parameters to the slave Bluetooth equipment, wherein the target connection parameters comprise the target connection interval parameters and starting update time; and updating the connection interval parameters of the BLE data communication connection according to the target connection parameters.
The target connection parameter is sent by a master Bluetooth device, when the master Bluetooth device establishes BLE connection with a slave Bluetooth device, the slave Bluetooth device can actively send a new connection interval parameter update request to the master Bluetooth device through a BLE data channel after determining that the connection parameter of the slave Bluetooth device changes, the master Bluetooth device can set a start update time after receiving the new connection interval parameter, package the connection interval parameter and the start update time between the two synchronous devices into the target connection parameter and send the target connection parameter to the slave Bluetooth device, and when the start update time arrives, the connection interval parameter of the BLE data communication connection is synchronously updated between the two devices.
It can be seen that the master bluetooth device can know that the connection parameters of the slave bluetooth device have changed, and by transmitting the target connection parameters to the slave bluetooth device, the master bluetooth device can negotiate new connection parameters with the slave bluetooth device. This negotiation procedure helps to ensure that both parties to the communication use the same connection parameters to provide consistent communication quality and performance.
