Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments that can be derived by one of ordinary skill in the art from the embodiments given herein are intended to be within the scope of the present disclosure.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The processor provided in the embodiments of the present application is described in detail with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
First, some communication modes between the master and the slave are described.
In the first case: the master machine can send a request for updating the Bluetooth connection parameters to the slave machine, then receive response information returned by the slave machine, send a notice for updating the Bluetooth connection parameters to the slave machine, and appoint a time point as the time point for updating the Bluetooth connection parameters through the notice and the slave machine. The slave updates the old bluetooth connection parameters to the new bluetooth connection parameters notified by the master at the time point of updating the bluetooth connection parameters.
In the second case: the master may first send a notification to the slave to update the bluetooth connection parameter, and the slave may agree with a time point through the notification as a time point for updating the bluetooth connection parameter. The slave updates the old bluetooth connection parameters to the new bluetooth connection parameters notified by the master at the time point of updating the bluetooth connection parameters.
In the third case: the slave computer can firstly send a request for updating the Bluetooth connection parameters to the host computer, then receive response information returned by the host computer, then receive a notice for updating the Bluetooth connection parameters sent by the host computer, take a time point specified in the notice as a time point for updating the Bluetooth connection parameters, and update the old Bluetooth connection parameters to new Bluetooth connection parameters notified by the host computer at the time point.
In many cases, the slave still receives packets according to the old bluetooth connection parameters before the new bluetooth connection parameters are enabled, and may skip receiving multiple packets from the master. When the master needs to send a data packet to the slave at a higher rate, the slave skips receiving a plurality of data packets according to the old bluetooth connection parameters before the specified time point, which may cause time delay and reduce data communication efficiency.
Fig. 1 is a schematic flowchart of a data processing method according to an embodiment of the present application.
The execution main body of the data processing method in this embodiment may be a slave, or may be a device including a slave.
S102, acquiring parameter updating information, and acquiring a first time delay range parameter from the parameter updating information; the first time delay range parameter is used for representing the time interval between the data packets sent by the two adjacent receiving hosts of the slave; the master machine and the slave machine are in communication connection based on a Bluetooth protocol.
The master in this embodiment may be a BLE master, and the slave may be a BLE slave. The BLE host and the BLE slave are in communication connection based on a Bluetooth protocol. The master and the slave can also be other master devices and slave devices which are connected through Bluetooth protocol communication. The Bluetooth connection parameters can be preset between the host and the slave, and communication connection is carried out according to the set Bluetooth connection parameters.
In specific implementation, the master may send and receive data packets to and from the slave according to the set bluetooth connection parameters. And correspondingly to the host, the slave can receive the data packet sent by the host and send the data packet to the host according to the Bluetooth connection parameters.
The bluetooth connection parameters may include a connection interval parameter, a connection timeout parameter, and a delay range parameter.
The connection interval parameter may be a connection interval (connection interval), the connection timeout parameter may be a connection timeout (connection timeout), and the latency range parameter may be a slave latency (latency). The interval between the master and the slave is called a connection interval. Connection timeout may be understood as the parameter sets a time threshold within which the master and slave will automatically disconnect if no communication connection occurs.
The slave time delay can represent the time interval between two adjacent times of receiving the data packets sent by the master by the slave. In addition, the master and the slave need to maintain Connection through periodic "handshakes", each "handshake" is regarded as a Connection Event (Connection Event), and each Connection Event has an Event count (Event Counter). The slave computer delays, which can also be understood as that the slave computer can skip listening to a plurality of connection events, so as to realize lower power consumption, and the number of connection events skipped from listening by the slave computer is the slave computer delay. For example, if the slave has a latency of 2, the slave may skip receiving a packet twice for each packet received.
Allowing slaves to skip a certain number of connection events in the bluetooth protocol does not have to listen to save power consumption, but the master has to actively send handshake information at set connection intervals. The master does not receive a reply when the slave skips the snoop connection event.
The various bluetooth connection parameters may be described below in conjunction with fig. 2. Fig. 2 is a first interaction diagram of a master and a slave according to an embodiment of the present disclosure.
Referring to fig. 2, T denotes a transmission packet, and R denotes a reception packet. In case the slave does not skip the snoop connection event, the send packet of the master corresponds to the receive packet of the slave, and vice versa. In the case where the slave skips the snoop connection event, the master performs transmitting and receiving the data packet, and the slave does not perform transmitting and receiving the data packet. Even if the two parties do not have any valid data to interact, a periodic handshake is necessary to maintain the connection.
When one-time handshake is carried out, for the host, a data packet is sent to the slave, and then the data packet sent by the slave is received; for the slave, the data packet sent by the host is received first, and then the data packet is sent to the host. The interval between the two handshakes is the connection interval in the aforementioned bluetooth connection parameters. In fig. 2, the slave performs one handshake at time 201, skipping two handshakes, performs another handshake at time 202, skips two handshakes, and performs another handshake. The slave latency in figure 2 is 2.
The parameter update information may be used to update the bluetooth connection parameters of the master and the slave. The parameter update information may be transmitted from the master to the slave, or may be transmitted from the slave to the master.
The first delay range parameter obtained from the parameter update information may be a slave delay characterizing a time interval between two adjacent slave receiving data packets sent by the master.
Optionally, obtaining parameter update information includes: when a first updating request is sent to a host, acquiring the first updating request; or receiving a second updating request sent by the host; alternatively, a first update notification sent by the host is received.
The parameter update information may be one of a first update request, a second update request, and a first update notification. Wherein:
(a1) the first update request may be a parameter update request sent from the slave to the master for updating the bluetooth connection parameter, and specifically, may be a parameter update request sent from the slave to the master for updating the delay range parameter. After receiving the first update request, the master may return corresponding response information to the slave, and if the response information is used to characterize that the master receives the first update request, the master further sends a parameter update notification for updating the delay range parameter to the slave.
(a2) The second update request may be a parameter update request sent by the master to the slave for updating the bluetooth connection parameter, and specifically, may be a parameter update request sent by the master to the slave for updating the delay range parameter. After sending the second update request, the master may receive corresponding response information returned by the slave, and if the response information is used to characterize that the slave receives the second update request, the master further sends a parameter update notification for updating the delay range parameter to the slave.
(a3) The first update notification may be a parameter update notification that is sent by the master directly to the slave without sending any request, and specifically, may be a parameter update notification that is sent by the master to the slave and is used for updating the delay range parameter.
It should be noted that only the master can send out the parameter update notification, and the slave cannot send out the parameter update notification.
And S104, reading a second time delay range parameter used by the current communication connection with the host.
And the slave machine reads the time delay range parameter used when in communication connection with the host machine as a second time delay range parameter.
A conventional process for updating the delay bound parameter may be described herein in connection with fig. 3. Fig. 3 is a second interaction diagram of a master and a slave according to an embodiment of the present disclosure.
Referring to fig. 3, T denotes a transmission packet, and R denotes a reception packet. In case the slave does not skip the snoop connection event, the send packet of the master corresponds to the receive packet of the slave, and vice versa. In the case where the slave skips the snoop connection event, the master performs transmitting and receiving the data packet, and the slave does not perform transmitting and receiving the data packet. Even if the two parties do not have any valid data to interact, a periodic handshake is necessary to maintain the connection.
In fig. 3, at time 201, the host issues a parameter update notification, which specifies time 202 as the effective time of the first latency range parameter. The slave performs one handshake at time point 201 according to the second delay range parameter, and skips two handshakes. When the first delay time range parameter is valid at time point 202, the handshake is not skipped from time point 202, and multiple handshakes are continuously performed.
And S106, determining the minimum value of the first time delay range parameter and the second time delay range parameter as a target parameter.
And comparing the values of the first delay range parameter and the second delay range parameter, and taking the smaller one of the values of the first delay range parameter and the second delay range parameter, namely the minimum value of the first delay range parameter and the second delay range parameter, as the target parameter.
If the first delay range parameter is greater than the second delay range parameter, it indicates that the new delay range parameter is greater than the old delay range parameter, that is, the number of connection events skipped by the slave is increased from small to large, and at this time, the new delay range parameter should not be enabled immediately, because the parameter update request has a possibility of being rejected, if the slave immediately adopts the new delay range parameter, the slave may miss a data packet sent by the host, resulting in data loss.
If the first delay range parameter is equal to the second delay range parameter, the new delay range parameter is equal to the old delay range parameter, and the delay range parameter does not need to be updated.
If the first time delay range parameter is smaller than the second time delay range parameter, the new time delay range parameter is smaller than the old time delay range parameter, that is, the number of connection events for the slave to skip monitoring is reduced from number to number, and under the condition, the risk of data loss does not exist, the new time delay range parameter can be allowed to take effect immediately, so that the communication delay between the master and the slave is effectively reduced.
And S108, receiving the data packet sent by the host according to the target parameter.
And the slave receives the data packet sent by the host according to the smaller one of the first time delay range parameter and the second time delay range parameter.
Here, the effect of receiving the data packet transmitted by the master from the slave according to the target parameter when the first delay time range parameter is smaller than the second delay time range parameter can be described with reference to fig. 4. Fig. 4 is a third schematic interaction diagram of a master and a slave according to an embodiment of the present application.
Referring to fig. 4, T denotes a transmission packet, and R denotes a reception packet. In case the slave does not skip the snoop connection event, the send packet of the master corresponds to the receive packet of the slave, and vice versa. In the case where the slave skips the snoop connection event, the master performs transmitting and receiving the data packet, and the slave does not perform transmitting and receiving the data packet. Even if the two parties do not have any valid data to interact, a periodic handshake is necessary to maintain the connection.
In fig. 3, at time 201, the host issues a parameter update notification, which specifies time 202 as the effective time of the first latency range parameter. If the first delay range parameter is smaller than the second delay range parameter, the slave does not skip the handshake from the time point 201 according to the first delay range parameter, and continuously performs multiple handshakes.
Optionally, after receiving the data packet sent by the host according to the target parameter, the data processing method further includes: receiving first response information returned by the host according to the first updating request; the first response information is used for representing that the host rejects the first updating request; and receiving the data packet sent by the host according to the second time delay range parameter.
The master may receive the first update request sent by the slave and may reject the first update request sent by the slave. When the slave receives response information which is returned by the master according to the first updating request and rejects the first updating request, the slave also receives a data packet sent by the master according to the original time delay range parameter, namely the second time delay range parameter.
After the value of the time delay range parameter is actively triggered to be updated, if the first time delay range parameter is smaller than the second time delay parameter, the slave machine can enable the first time delay range parameter with the smaller value to take effect immediately, and even if the slave machine receives first response information which is sent by the host machine and refuses the first updating request after a period of time, the slave machine can immediately recover the second time delay range parameter which is originally used, and data loss is avoided.
For example, the slave sends a first update request to the master at time T1, where the first update request carries a first delay range parameter X1. The slave reads the currently used second delay time range parameter Y1 at time point T1, X1< Y1. At the time point T1, the slave updates the value of the delay spread parameter used by the slave from the second delay spread parameter Y1 to the first delay spread parameter X1. And the slave receives the data packet transmitted by the master according to the first time delay range parameter X1 from the time point T1. The master receives the first update request at time point T1, and sends corresponding first response information to the slave according to the first update request at time point T2, wherein the first response information is used for indicating that the first update request is rejected. The slave receives the first response information at a time point T3. At the time point T3, the slave updates the value of the delay spread parameter used by the slave from the first delay spread parameter X1 to the second delay spread parameter Y1. From the time point T3, the slave receives the data packet transmitted by the master according to the second delay range parameter Y1.
Optionally, the parameter update message carries a first time parameter; the data processing method further comprises: determining a parameter updating time point according to the first time parameter; and receiving the data packet sent by the host according to the first time delay range parameter at the parameter updating time point.
The parameter updating notice sent by the host to the slave carries the first time parameter. The first time parameter may be a host-specified point in time. The slave may determine a time point designated by the master as a parameter update time point. The master machine and the slave machine can jointly execute the numerical value updating of the time delay range parameter at the parameter updating time point.
If the slave receives the data packet sent by the host according to the old time delay range parameter, namely the second time delay range parameter, before the parameter updating time point after the execution of the step S102, the slave updates the value of the time delay range parameter from the second time delay range parameter to the first time delay range parameter at the parameter updating time point; if the slave receives the data packet sent by the master according to the new delay range parameter, that is, the first delay range parameter, before the parameter update time point after the execution of S102, the slave does not need to perform any value update operation at the parameter update time point.
For example, the master sends a first update notification to the slave at a time point T1, where the first update notification carries a first time parameter T3 and a first delay range parameter X2, and the slave receives the first update notification at a time point T2, and reads a second delay range parameter Y2 used currently, where X2> Y2. The slave, after comparing the values of X2 and Y2, still receives the data packet sent by the master according to the second delay range parameter Y2 between time T2 and time T3. And the master machine and the slave machine carry out numerical value updating of the time delay range parameter at the time point T3 together, and the value of the time delay range parameter is updated from the second time delay range parameter Y2 to the first time delay range parameter X2. The slave receives the data packet transmitted by the master according to the first delay range parameter X2 from the time point T3.
For another example, the master sends a first update notification to the slave at a time point T1, where the first update notification carries a first time parameter T3 and a first time delay range parameter X3, and the slave receives the first update notification at a time point T2, and reads a second time delay range parameter Y3 used currently, where X3< Y3. After comparing the values of X3 and Y3, the slave updates the value of the delay spread parameter used by the slave from the second delay spread parameter Y3 to the first delay spread parameter X3 at time T2. The master and the slave update the value of the delay time range parameter at the time point T3 together, and the slave updates the value of the delay time range parameter in advance, so that the slave actually receives the data packet transmitted by the master from the time point T2 according to the delay time range parameter X3, that is, the slave receives the data packet transmitted by the master according to the first delay time range parameter X3 no matter between T2 and T3 or after the time points T3 and T3.
In the embodiment of the data processing method shown in fig. 1, parameter update information is obtained, and a first delay range parameter is obtained from the parameter update information; the first time delay range parameter is used for representing the time interval between the data packets sent by the two adjacent receiving hosts of the slave; the host machine is in communication connection with the slave machine based on a Bluetooth protocol; reading a second time delay range parameter used by the current communication connection with the host; determining the minimum value of the first time delay range parameter and the second time delay range parameter as a target parameter; and receiving the data packet sent by the host according to the target parameter. According to the technical scheme of the embodiment of the application, the data packet is received according to the minimum value of the first time delay range parameter and the currently used second time delay range parameter in the parameter updating information, so that the communication delay between the host and the slave can be reduced under the condition of avoiding data loss, and the data communication efficiency is improved.
