Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
First, describing an application scenario of the present disclosure, after a transmitting end and a receiving end are connected by a BLE technology, it is currently determined whether to disconnect bluetooth connections of the transmitting end and the receiving end by the following means: the method comprises the steps that a sending end sends a communication packet to a receiving end according to a preset packet sending period in packet sending time, and the receiving end monitors the communication packet sent by the sending end according to a monitoring period, wherein the receiving end does not receive the communication packet sent by the sending end in the current monitoring period or the received communication packet is an error packet, enters a dormant state and wakes up in the next monitoring period to continue monitoring the communication packet sent by the sending end, so that if the receiving end is determined to monitor a correct communication packet in the packet sending time, normal communication packet transmission exists between the receiving end and the sending end, at the moment, the Bluetooth connection of the receiving end and the sending end does not need to be disconnected, on the contrary, if the receiving end is determined not receive a communication packet or receives all error packets in the packet sending time, the normal communication packet transmission does not exist between the receiving end and the sending end, at the moment, the Bluetooth connection of the receiving end and the sending end is disconnected, however, in the process of monitoring the communication packet by the receiving end, because the receiving end does not monitor the communication packet sent by the sending end in the current monitoring period or the received communication packet is an error packet, the receiving end needs to enter the sleep mode and continue monitoring the communication packet in the next monitoring period, the sending end cannot send the communication packet to the receiving end in time, and the communication packet is delayed.
In order to solve the above problem, the present disclosure may determine whether the first monitoring result of the current monitoring period satisfies the continuous monitoring trigger condition after the current monitoring period is ended, and continue to monitor the communication packet within the packet sending time when the first monitoring result satisfies the continuous monitoring trigger condition.
The present disclosure will be described in detail with reference to specific examples.
Fig. 1 is a flowchart of a method for listening to a communication packet according to an exemplary embodiment of the present disclosure, which is applied to a receiving end, and as shown in fig. 1, the method includes:
in step 101, a communication packet sent by a sending end in a packet sending time is monitored in a current monitoring period.
The packet sending time may be a timeout parameter in the BLE protocol specification, for example, the packet sending time may include a start time, an end time, and a packet sending duration at which the sending end sends a communication packet, and if the receiving end monitors a correct communication packet within the packet sending time, the start time and the end time in the packet sending time may be reset, for example, if the receiving end monitors a correct communication packet at a certain time in the current monitoring period, the certain time in the current monitoring period may be updated to the start time of the packet sending time, and the end time is updated according to the updated start time and the updated packet sending duration.
In this step, the listening period of the receiving end may be determined by the following method: first, a plurality of packet listening times within the packet sending time are determined according to a latency parameter (corresponding to a packet receiving interval) and the packet sending time in the BLE protocol specification, for example, a first packet listening time within the packet sending time may be determined according to a start time and the latency parameter, a second packet listening time within the packet sending time may be determined according to the first packet listening time and the latency parameter, and so on, a plurality of packet listening times within the packet sending time may be determined, then, each packet listening time is taken as a time start point, and a monitoring period is formed with a preset time period as a time duration, which is only illustrated by way of example, and is not limited by the present disclosure.
In step 102, when the current listening period listening ends, it is determined whether the first listening result satisfies a continuous listening triggering condition.
In this step, the continuous listening triggering condition may include: determining that the communication packet is not received in the current monitoring period according to the first monitoring result; or determining that the communication packet received in the current monitoring period is an error packet according to the first monitoring result.
In step 103, when the first monitoring result meets the continuous monitoring trigger condition, the communication packet in the packet sending time is monitored continuously.
In the related art, the communication packet sent by the sending end is not monitored in the current monitoring period or the monitored communication packet is an error packet, and then the communication packet enters the dormant state, so that the communication packet sent by the sending end in the packet sending time can be monitored continuously when the first monitoring result meets the continuous monitoring triggering condition, and the monitoring delay of the communication packet in the related art is avoided.
By adopting the method, whether the first monitoring result of the current monitoring period meets the continuous monitoring triggering condition or not can be determined after the current monitoring period is finished, and the communication packet in the packet sending time is monitored continuously when the first monitoring result meets the continuous monitoring triggering condition, so that the receiving end can receive the communication packet sent by the sending end in time, and the delay of the communication packet caused by the fact that the receiving end needs to monitor the communication packet in the next monitoring period is avoided.
Fig. 2 is a flowchart of a method for listening to a communication packet according to an exemplary embodiment of the present disclosure, which is applied to a receiving end, and as shown in fig. 2, the method includes:
in step 201, a communication packet sent by a sending end in a packet sending time is monitored in a current monitoring period.
The packet sending time may be a timeout parameter in the BLE protocol specification, for example, the packet sending time may include a start time, an end time, and a packet sending duration at which the sending end sends a communication packet, and if the receiving end monitors a correct communication packet within the packet sending time, the start time and the end time in the packet sending time may be reset, for example, if the receiving end monitors a correct communication packet at a certain time in the current monitoring period, the certain time in the current monitoring period may be updated to the start time of the packet sending time, and the end time is updated according to the updated start time and the updated packet sending duration.
In this step, the listening period of the receiving end may be determined by the following method: first, a plurality of packet listening times within the packet sending time are determined according to a latency parameter (corresponding to a packet receiving interval) and the packet sending time in the BLE protocol specification, for example, a first packet listening time within the packet sending time may be determined according to a start time and the latency parameter, a second packet listening time within the packet sending time may be determined according to the first packet listening time and the latency parameter, and so on, a plurality of packet listening times within the packet sending time may be determined, then, each packet listening time is taken as a time start point, and a monitoring period is formed with a preset time period as a time duration, which is only illustrated by way of example, and is not limited by the present disclosure.
In step 202, at the end of the current listening period, it is determined whether the first listening result satisfies a continuous listening triggering condition.
In this step, the continuous listening triggering condition includes: determining that the communication packet is not received in the current monitoring period according to the first monitoring result; or, determining that the communication packet received in the current monitoring period is an error packet according to the first monitoring result, so that the receiving end enters a sleep state when the first monitoring result meets the continuous monitoring trigger in the related art, and wakes up in the next monitoring period to continue monitoring the communication packet, thereby causing the monitoring delay of the communication packet.
In one possible implementation, whether the communication packet is an error packet may be determined by: the communication packet sent by the sending end includes the check data and the communication data, so that the communication data can be calculated to obtain a communication result, and whether the communication result is consistent with the check data or not is determined, when the communication result is consistent with the check data, the communication packet is determined to be a correct communication packet, and when the communication result is inconsistent with the check information, the communication packet is determined to be an error packet.
When determining that the first listening result satisfies the continuous listening triggering condition, executing steps 203 and 205;
upon determining that the first listening result does not satisfy the persistent listening trigger condition, step 204 is performed.
In step 203, the communication packet in the packet sending time is monitored continuously to obtain a second monitoring result.
The method and the device avoid the condition that the receiving end enters the dormant state when the first monitoring result meets the continuous monitoring trigger in the related art, and therefore the second monitoring result can be obtained in time by keeping continuous monitoring.
In step 204, a sleep state is entered.
In step 205, it is determined whether the second snoop result satisfies a snoop end condition.
Wherein, the listening ending condition may include: determining to receive a correct communication packet according to the second monitoring result; or the total time for monitoring the communication packet is greater than or equal to the packet sending time, for example, when the packet sending duration of the packet sending time is 30s, if the total time for the receiving end to monitor the communication packet in the packet sending time is 25s, the monitoring ending condition is still not met, and if the total time for the receiving end to monitor the communication packet is 31s, the monitoring ending condition is met, and the communication packet does not need to be monitored continuously.
When it is determined that the second monitoring result satisfies the monitoring ending condition, execute step 206;
and returning to step 203 when the second interception result is determined not to satisfy the interception end condition.
In step 206, listening for the communication packet is terminated.
In this step, when the monitoring end condition is that a correct communication packet is determined to be received according to the second monitoring result, after the correct communication packet is received in step 205, if the correct communication packet is a data packet, a first response message is sent to the sending end, and after a response feedback message sent by the sending end is received, the sending end enters a dormant state; and if the correct communication packet is an empty packet, sending a second response message to the sending end, and entering a dormant state.
By adopting the method, whether the first monitoring result of the current monitoring period meets the continuous monitoring triggering condition or not can be determined after the current monitoring period is finished, and the communication packet in the packet sending time is monitored continuously when the first monitoring result meets the continuous monitoring triggering condition, so that the receiving end can receive the communication packet sent by the sending end in time, and the delay of the communication packet caused by the fact that the receiving end needs to monitor the communication packet in the next monitoring period is avoided.

By adopting the device, whether the first monitoring result of the current monitoring period meets the continuous monitoring triggering condition or not can be determined after the current monitoring period is finished, and the communication packet in the packet sending time is continuously monitored when the first monitoring result meets the continuous monitoring triggering condition, so that the receiving end can timely receive the communication packet sent by the sending end, and the communication packet delay caused by the fact that the receiving end needs to monitor the communication packet in the next monitoring period is avoided.
