Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The processor provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings by using specific embodiments and application scenarios thereof.
First, some communication methods of the master and the slave will be described.
First case: the host computer can firstly send a request for updating the Bluetooth connection parameters to the slave computer, then receive response information returned by the slave computer, and then send a notification for updating the Bluetooth connection parameters to the slave computer, and a time point is appointed as a time point for updating the Bluetooth connection parameters by the notification and the slave computer. The slave updates the old bluetooth connection parameters to the new bluetooth connection parameters notified by the master at the time point of the update of the bluetooth connection parameters.
Second case: the host may first send a notification to the slave to update the bluetooth connection parameters, and by means of the notification and the slave, a time point is agreed as a time point for updating the bluetooth connection parameters. The slave updates the old bluetooth connection parameters to the new bluetooth connection parameters notified by the master at the time point of the update of the bluetooth connection parameters.
Third case: the slave can firstly send a request for updating the bluetooth connection parameters to the host, then receive response information returned by the host, then receive notification of updating the bluetooth connection parameters sent by the host, take a time point appointed in the notification 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 at the time point.
In many of the above cases, the slave still receives the data packet according to the old bluetooth connection parameters before the new bluetooth connection parameters are validated, and may skip the receiving host to generate multiple data packets. When the host needs to send data packets to the slave according to a higher rate, the slave skips receiving a plurality of data packets according to the old bluetooth connection parameters before a designated time point, which may cause time delay and reduce data communication efficiency.
Fig. 1 is a flow chart of a data processing method according to an embodiment of the present application.
The execution subject of the data processing method in this embodiment may be a slave or a device including a slave.
S102, acquiring parameter updating information, and acquiring a first delay range parameter from the parameter updating information; the first time delay range parameter is used for representing the time interval between two adjacent secondary receiving host machine transmitted data packets; the master and the slave are in communication connection based on the 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 the Bluetooth protocol. The master and the slave can also be other master devices and slave devices which are in communication connection through the Bluetooth protocol. 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 particular, the host may send data packets to the slave and receive data packets from the slave according to the set bluetooth connection parameters. And correspondingly, 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, a latency range parameter.
The connection interval parameter may be a connection interval (connection interval), the connection timeout parameter may be a connection timeout (connection supervision timeout), and the delay range parameter may be a slave delay. The interval between the master and the slave is called a connection interval. A connection timeout is understood to mean that the parameter sets a time threshold within which the master and slave will automatically disconnect if no communication connection occurs.
The slave latency may characterize the time interval between two adjacent slave receivers of packets sent by the master. The master and the slave need to maintain the Connection through periodic "handshakes", each of which is regarded as a Connection Event (Connection Event), and each Connection Event has an Event Counter (Event Counter). The slave delays, and it can also be understood that the slave can skip interception of a plurality of connection events, so that lower power consumption is realized, and the number of connection events that the slave skips interception is the slave delays. For example, the slave delay is 2, and the slave can skip receiving the data packet twice every time the data packet is received.
In the bluetooth protocol, the slave is allowed to skip a certain number of connection events without interception, so as to save power consumption, but the host must actively send handshake information according to a set connection interval. When the slave skips listening for a connection event, the host does not receive a reply.
The various bluetooth connection parameters may be described below in connection with fig. 2. Fig. 2 is a schematic diagram of a first interaction between a master and a slave according to an embodiment of the present application.
As shown in fig. 2, t represents a transmission packet, and R represents a reception packet. In the case that the slave does not skip the snoop connection event, the transmitted data packet of the master corresponds to the received data packet of the slave, and vice versa. In the case that the slave skips the snoop connection event, the master performs the transmission and reception of the data packet, and the slave does not perform the transmission and reception of the data packet. Even if the two parties do not have any valid data to interact, they must handshake periodically to maintain the connection.
When one handshake is carried out, for a host, firstly, a data packet is sent to a 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 bluetooth connection parameters. In fig. 2, the slave performs a handshake at time 201, skips two handshakes, performs another handshake at time 202, skips two handshakes, and performs another handshake. The slave latency in fig. 2 is 2.
The parameter update information may be used to update bluetooth connection parameters of the master and the slave. The parameter update information may be sent from the master to the slave or from the slave to the master.
The first delay range parameter obtained from the parameter update information may be a slave delay used to characterize a time interval between two neighboring slave receiving packets sent by the host.
Optionally, acquiring the parameter update information includes: when a first update request is sent to a host, acquiring the first update request; or receiving a second update request sent by the host; or, receiving a first update notification sent by the host.
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 host for updating the bluetooth connection parameter, and specifically, may be a parameter update request sent from the slave to the host for updating the delay range parameter. After receiving the first update request, the host may return corresponding response information to the slave, and if the response information is used to characterize that the host receives the first update request, the host may further send 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 host to the slave for updating the bluetooth connection parameter, and specifically, may be a parameter update request sent by the host to the slave for updating the delay range parameter. After sending the second update request, the host 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 host may further send a parameter update notification for updating the delay range parameter to the slave.
(a3) The first update notification may be a parameter update notification for updating the bluetooth connection parameter, which is directly transmitted by the host to the slave without any request being transmitted, and specifically may be a parameter update notification for updating the delay range parameter, which is transmitted by the host to the slave.
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.
S104, reading a second delay range parameter used by the current communication connection with the host.
The slave reads a delay range parameter used when in communication connection with the host as a second delay range parameter.
A conventional process of updating the delay range parameter may be described herein in connection with fig. 3. Fig. 3 is a second interaction schematic diagram of a master and a slave according to an embodiment of the present application.
As shown in fig. 3, t represents a transmission packet, and R represents a reception packet. In the case that the slave does not skip the snoop connection event, the transmitted data packet of the master corresponds to the received data packet of the slave, and vice versa. In the case that the slave skips the snoop connection event, the master performs the transmission and reception of the data packet, and the slave does not perform the transmission and reception of the data packet. Even if the two parties do not have any valid data to interact, they must handshake periodically to maintain the connection.
In fig. 3, at time 201, the host issues a parameter update notification specifying time 202 as the effective time of the first delay range parameter. The slave performs a handshake at a time point 201 according to the second delay range parameter, and skips the two handshakes. The first delay range parameter is validated at time 202, and the handshake is not skipped from time 202, and the multiple handshakes are continued.
S106, determining the minimum value of the first delay range parameter and the second delay range parameter as a target parameter.
Comparing the values of the first delay range parameter and the second delay range parameter, and taking the smaller one 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 means that the new delay range parameter is greater than the old delay range parameter, that is, the number of connection events that the slave skips interception will be less and more, at this time, the new delay range parameter should not be validated immediately, because the parameter update request is possible to be refused, if the slave immediately adopts the new delay range parameter, the slave may miss a data packet sent by the host, and data is lost.
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 delay range parameter is smaller than the second delay range parameter, the new delay range parameter is smaller than the old delay range parameter, namely the number of connection events for which the slave computer skips interception is variable and less, and the risk of data loss does not exist under the condition, so that the new delay range parameter can be allowed to take effect immediately, and the communication delay between the host computer and the slave computer is effectively reduced.
S108, receiving the data packet sent by the host according to the target parameter.
The slave receives the data packet sent by the host according to the smaller one of the first delay range parameter and the second delay range parameter.
The effect of the slave receiving the data packet sent by the host according to the target parameter in the case where the first delay range parameter is smaller than the second delay range parameter can be described with reference to fig. 4. Fig. 4 is a third interaction schematic diagram of a master and a slave according to an embodiment of the present application.
As shown in fig. 4, t represents a transmission packet, and R represents a reception packet. In the case that the slave does not skip the snoop connection event, the transmitted data packet of the master corresponds to the received data packet of the slave, and vice versa. In the case that the slave skips the snoop connection event, the master performs the transmission and reception of the data packet, and the slave does not perform the transmission and reception of the data packet. Even if the two parties do not have any valid data to interact, they must handshake periodically to maintain the connection.
In fig. 3, at time 201, the host issues a parameter update notification specifying time 202 as the effective time of the first delay range parameter. If the first delay range parameter is smaller than the second delay range parameter, the slave machine 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 update request; the first response information is used for representing that the host refuses the first update request; and receiving the data packet sent by the host according to the second time delay range parameter.
The host may receive the first update request sent by the slave, or may reject the first update request sent by the slave. When the slave receives response information which is returned by the host and refuses the first updating request according to the first updating request, the slave also receives a data packet sent by the host according to the original time delay range parameter, namely the second time delay range parameter.
After the numerical value of the active triggering delay range parameter is updated, if the first delay range parameter is smaller than the second delay range parameter, the slave can enable the first delay range parameter with smaller numerical value to be effective immediately, and even if the slave receives the first response information which is sent by the host and refuses the first updating request after a period of time, the slave can also recover the originally used second delay range parameter immediately and cannot cause data loss.
For example, the slave sends a first update request to the master at a time point T1, where the first update request carries a first delay range parameter X1. The slave reads the second delay range parameter Y1, X1< Y1 currently used at time T1. At the time point T1, the slave updates the value of the delay range parameter used by the slave from the second delay range parameter Y1 to the first delay range parameter X1. The slave receives the data packet sent by the host according to the first delay range parameter X1 from the time point T1. The host receives the first update request at a time point T1, and sends corresponding first response information to the slave according to the first update request at a time point T2, wherein the first response information is used for representing that the first update request is refused. The slave receives the first response message at the time point T3. At the time point T3, the slave updates the value of the delay range parameter used by the slave from the first delay range parameter X1 to the second delay range parameter Y1. From the time point T3, the slave receives the data packet sent by the host according to the second delay range parameter Y1.
Optionally, the parameter update information carries a first time parameter; the data processing method further comprises the following steps: determining a parameter updating time point according to the first time parameter; and at the parameter updating time point, receiving the data packet sent by the host according to the first time delay range parameter.
The parameter update notification sent by the host to the slave carries a first time parameter. The first time parameter may be a host-specified point in time. The slave may determine the time point designated by the master as a parameter update time point. The master and the slave can jointly execute the numerical value update of the delay range parameter at the parameter update time point.
If the slave machine receives the data packet sent by the host machine according to the old time delay range parameter, namely the second time delay range parameter, before the parameter updating time point after the step S102 is executed, the slave machine 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 host according to the new delay range parameter, that is, the first delay range parameter, before the parameter update time point after S102 is executed, 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, the slave receives the first update notification at a time point T2, and the slave reads a second delay range parameter Y2, X2> Y2 currently used. After comparing the values of X2 and Y2, the slave still receives the data packet sent by the host according to the second delay range parameter Y2 between the time point T2 and the time point T3. The host computer and the slave computer update the values of the delay range parameters at the time point T3, and update the values of the delay range parameters from the second delay range parameter Y2 to the first delay range parameter X2. Then, starting at the time point T3, the slave receives the data packet sent by the host according to the first delay range parameter X2.
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 delay range parameter X3, the slave receives the first update notification at a time point T2, and the slave reads a second delay range parameter Y3 currently used, where X3< Y3. After comparing the values of X3 and Y3, the slave updates the value of the delay range parameter used by the slave from the second delay range parameter Y3 to the first delay range parameter X3 at the time point T2. The host and the slave perform the value update of the delay range parameter at the time point T3 together, and since the slave has performed the value update of the delay range parameter in advance, the slave actually receives the data packet sent by the host according to the delay range parameter X3 from the time point T2, that is, the slave receives the data packet sent by the host according to the first delay range parameter X3, both between T2 and T3 and after the time point T3.
In the embodiment of the data processing method shown in fig. 1, parameter update information is acquired, and a first delay range parameter is acquired from the parameter update information; the first time delay range parameter is used for representing the time interval between two adjacent secondary receiving host machine transmitted data packets; the host computer is in communication connection with the slave computer based on a Bluetooth protocol; reading a second delay range parameter currently used by communication connection with the host; determining the minimum value of the first delay range parameter and the second 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, the data packet is received according to the minimum value of the first delay range parameter and the currently used second delay range parameter in the parameter updating information, so that communication delay between the host computer and the slave computer can be reduced under the condition of avoiding data loss, and data communication efficiency is improved.
