Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Fig. 1A is a flowchart illustrating a disconnection method of a bluetooth low energy connection according to an exemplary embodiment, and fig. 1B is a scene diagram illustrating a disconnection method of a bluetooth low energy connection according to an exemplary embodiment; the disconnection method of the bluetooth low energy connection can be applied to a first device (for example, a bluetooth low energy remote controller, a television, and other intelligent devices supporting bluetooth low energy communication), as shown in fig. 1A, the disconnection method of the bluetooth low energy connection includes the following steps:
in step 101, a link down request message sent by the second device is received.
In an embodiment, a bluetooth connection is established between the first device and the second device, and when the second device wants to disconnect the bluetooth connection, the link layer may be controlled to send a link disconnection request message LL _ TERMINATE _ IND to the link layer of the first device. For example: the first device is a Bluetooth low-power-consumption remote controller, the second device is a television, and when the television wants to disconnect the Bluetooth low-power-consumption remote controller, the link disconnection request message can be sent to the Bluetooth low-power-consumption remote controller.
In step 102, a first reply message is sent to the second device according to the link down request message.
In an embodiment, when the link layer of the first device receives the link disconnection request message LL _ TERMINATE _ IND, the first acknowledgement message LL _ ack may be returned to the link layer of the second device.
In step 103, after the first reply message is sent, the message sent by the second device is monitored within the time of the length of a first preset threshold, wherein the first preset threshold is not greater than the timeout link-breaking time.
In an embodiment, the first preset threshold may be empirical data determined by the bluetooth communication protocol stack according to a large amount of bluetooth communication data, and may be, for example, 5s, which is much shorter than the timeout link-down time (the timeout link-down time is typically 16 seconds or 31 seconds).
In one embodiment, a timing means of a first predetermined threshold length may be set after each transmission of the first reply message, and the first predetermined threshold is determined to be reached by determining whether the timing means has timed out.
In step 104, if a second response message returned by the second device according to the first response message is received within the time of the first preset threshold length, a chain scission operation is performed.
In an embodiment, after the link layer of the first device returns the first response message, if the link layer of the second device receives the first response message, the link layer of the first device may return a second response message, and if the link layer of the first device receives the second response message, the link-down operation may be performed immediately. For example, the first device starts the timing means after returning LL _ ack, performs a chain-breaking operation if a second response message returned by the second device is received at the next connection gap connection interval, and deletes the timing means.
In an embodiment, the first device performing the chain scission operation may include setting a state machine of a link layer to a ready state, and the link layer transmitting a request message to an upper application layer of the first device to complete the chain scission. It is sufficient that the upper layer of the first device performs the broken link setting in the related art.
In an exemplary scenario, as shown in fig. 1B, after receiving LL _ TERMINATE _ IND sent by a link layer of a second device 12 (here, a television is illustrated, and may also be other bluetooth devices such as a television) by a link layer of a first device 11 (here, a television is illustrated, and may also be other bluetooth devices), returning a first reply message LL _ ack, and continuing to monitor a message sent by the link layer of the second device, and after receiving a second reply message returned by the second device according to the first reply message, performing a chain scission operation.
In this embodiment, after the second device sends the link disconnection request message to the first device, the first device continues to monitor the message of the first device after returning to the first response message, and performs the link disconnection operation when monitoring the second response message returned by the second device according to the first response message within the time of the first preset threshold length, where the first preset threshold length may be M (M is greater than 1 and smaller than the link disconnection timeout time/connection gap) connection gaps, so as to solve the problem in the related art that the first device returns the response message and performs the link disconnection operation after receiving the link disconnection request, and the second device may not have a problem that the second device may perform the link disconnection operation only after waiting for the connection timeout because the second device does not receive the response message sent by the first device, thereby preventing the bluetooth link communication part of the second device from being blocked for a period of time, the user experience is optimized.
In an embodiment, the method further comprises:
and if the link disconnection request message sent by the second equipment is received within the time of the first preset threshold length, executing the operation of sending the first response message to the second equipment according to the link disconnection request message.
In an embodiment, the method further comprises:
and if the message sent by the second equipment is not received within the time of the first preset threshold length, performing chain scission operation.
In an embodiment, the method further comprises:
a timing means for setting a first predetermined threshold length after the first reply message is sent;
and determining whether the timing device is overtime or not by determining whether a first preset threshold is reached, and monitoring the message sent by the second equipment within the time of the length of the first preset threshold based on the first preset threshold.
In an embodiment, the method further comprises:
and if a second response message returned by the second equipment according to the first response message is received within the time of the first preset threshold length, sending a third response message to the second equipment.
Please refer to the following embodiments specifically to how to disconnect the bluetooth low energy connection.
Therefore, the method provided by the embodiment of the disclosure can solve the problem that in the related art, the first device returns the response message and performs the link down operation after receiving the link down request, and the second device may not have the problem that the second device can perform the link down operation only after the connection timeout because the response message sent by the first device is not received, thereby preventing the bluetooth link communication part of the second device from being blocked for a period of time, and optimizing the user experience.
The technical solutions provided by the embodiments of the present disclosure are described below with specific embodiments.
FIG. 2 is a flow chart illustrating a method for disconnecting a Bluetooth Low energy connection in accordance with an exemplary embodiment; the present embodiment uses the above method provided by the embodiment of the present disclosure, taking a process of disconnecting the bluetooth connection between the first device and the second device by the first device as an example, as shown in fig. 2, including the following steps:
in step 201, a link down request message sent by the second device is received.
In step 202, a first reply message is sent to the second device in accordance with the link down request message.
In step 203, after the first reply message is sent, the message sent by the second device is monitored within the time of the length of a first preset threshold, wherein the first preset threshold is not greater than the timeout link-breaking time, and step 204, step 205 or step 206 is executed.
In one embodiment, the description of steps 201-203 can refer to the description of steps 101-103 of the embodiment shown in fig. 1A, and will not be described in detail here.
In step 204, if no message is received within the time of the first preset threshold length, the second response message returned by the second device according to the first response message is sent to the second device, and a chain scission operation is performed.
In an embodiment, if the first device receives the second response message sent by the second device, it indicates that the second device has received the first response message returned by the first device, and if the first device and the second device need to send two LL-ack re-delinking operations according to the protocol specification, the first device may send the third response message to the second device and then perform the delinking operation.
In one embodiment, the protocol may also be agreed that the first device and the second device send back and forth P times LL-ack before performing the chain scission operation respectively.
In step 205, if the link disconnection request message sent by the second device is received within the time of the first preset threshold length, an operation of sending a first response message to the second device according to the link disconnection request message is performed.
In an embodiment, if the second device does not receive the first reply message returned by the first device, the second device may send a link disconnection request message in the next connection gap, and the first device may continue to perform the operation of step 203 after receiving the link disconnection request message and sending the first reply message to the second device.
In step 206, if the message sent by the second device is not received within the time of the first preset threshold length, a chain scission operation is performed.
In an embodiment, if the first device does not receive any message sent by the second device within the time of the first preset threshold length, it may be said that the first device does not receive the second response message returned by the second device, and the second device has performed the chain breaking operation, the first device may perform the chain breaking operation.
As an exemplary scenario, taking the example that the tv set sends a link-down request message to the remote controller as an example, after the tv set sends LL _ TERMINATE _ IND to the remote controller, the remote control sends a LL-ack message to the tv set and continues to listen for messages from the tv set for the next P (e.g.: 6) connection slots, if the LL-ack message sent by the television is monitored, the chain breaking operation can be directly executed according to the convention or the chain breaking operation can be executed after the LL-ack message is sent to the television, and if the tv is monitored for LL _ TERMINATE _ IND sent again, a LL-ack message is sent again to the tv set and listening to the tv set's messages continues for the next 6 connection slots, if no message of the television is monitored in the 6 connection gaps, the chain breaking operation can be directly executed according to the convention.
In this embodiment, when receiving a link disconnection request message sent by the second device within a time of a first preset threshold length, the first response message is continuously sent to the second device, so that a link disconnection request of the second device can be responded in time, and the problem that the second device can only execute a link disconnection operation after connection timeout because the first device does not respond is avoided; in addition, when any message sent by the second device is not received within the time of the first preset threshold length, the chain breaking operation is executed, so that the first device can be broken in time, and the Bluetooth link communication part of the first device is prevented from being blocked for a period of time; in addition, when a second response message returned by the second device according to the first response message is received within the time of the first preset threshold length, a third response message is returned to the second device, so that the second device can execute the chain scission operation when receiving the third response message, the time of the chain scission process of the second device is shortened, and the user experience is further optimized.
FIG. 3 is a flowchart illustrating a method for disconnecting a Bluetooth Low energy connection according to an example embodiment two; the disconnection method of the bluetooth low energy connection can be applied to a second device (for example, a bluetooth device such as a bluetooth low energy remote controller and a television), as shown in fig. 3, the disconnection method of the bluetooth low energy connection includes the following steps:
in step 301, a link down request message is sent to the first device.
In step 302, it is monitored whether a first reply message returned by the first device according to the link disconnection request message is received.

In an embodiment, the value of N may be obtained according to an agreement between the first device and the second device, but the maximum value of N may be a ratio of the timeout link-down time to the connection gap time. If the value of N is the ratio of the time of the link disconnection over time to the time of the connection gap, the time of the link disconnection of the second device is still the time of the link disconnection over time, and thus the value of N here is generally small, for example, 5.
In an embodiment, a value of N may be a fixed value agreed between the first device and the second device, for example, N is 5, that is, the first device does not need to determine whether to receive the second response message sent by the second device, and the first device sends the second response message 5 times; in yet another embodiment, the first device may further agree with the second device that if the first device receives a second response message sent by the second device, and the second device receives a third response message returned by the first device according to the second response message, the first device may stop sending the second response message.
In step 304, a chain scission operation is performed.
In an embodiment, the second device performing the chain scission operation may include setting a state machine of a link layer to a ready state, and the link layer transmitting a request message for completion of the chain scission to an upper application layer of the first device. It is sufficient that the upper layer of the first device performs the broken link setting in the related art.
In this embodiment, after sending the link disconnection request message to the first device, the second device monitors a message returned by the first device, and after monitoring the first response message sent by the first device, sends the second response message to the first device N times, and then performs the link disconnection operation, so that both the first device and the second device can perform the link disconnection operation in time, the bluetooth link communication portions of the first device and the second device are prevented from being blocked for a period of time, and the user experience is optimized.
In an embodiment, sending the second response message to the first device N times includes:
and starting the timing device after receiving the first response message, sending a second response message to the first equipment according to a preset time interval, and stopping sending the second response message when the timing device times out.
In an embodiment, sending the second response message to the first device N times includes:

and if the third response message returned by the first equipment according to the second response message is not received when the timing device times out, stopping sending the second response message when the timing device times out.
In an embodiment, the method further comprises:
when the first reply message is not received, an operation of transmitting a link-down request message to the first device is performed in a next connection gap.
In an embodiment, the method further comprises:
calculating the ratio of the overtime broken link time to the connection gap time;

The first method is as follows: the value of N may be a fixed value agreed between the first device and the second device, for example, N is 5, that is, the first device sends the second response message 5 times without determining whether the first device receives the second response message sent by the second device.
In an embodiment, the flow of the first method can refer to the embodiment shown in fig. 4B, and as shown in fig. 4B, the method includes the following steps:
in step 411, a timing means is started after receiving the first reply message, and a second reply message is sent to the first device at a preset time interval.
In an embodiment, the preset time interval may be one connection gap or two connection gaps, and the preset time interval may be agreed by the first device and the second device.
In step 412, the sending of the second reply message is stopped when the timing means times out.
The second method comprises the following steps: the first device may also agree with the second device that if the first device receives a second response message sent by the second device and the second device receives a third response message returned by the first device according to the second response message, the first device may stop sending the second response message, and if the second device does not receive the third response message returned by the first device, the second device sends the second response message N times.
In an embodiment, the flow of the second mode can refer to the embodiment shown in fig. 4C, and as shown in fig. 4C, the method includes the following steps:
in step 421, after receiving the first response message, a timing device is started, a second response message is sent to the first device at a preset time interval and the message sent by the first device is monitored, and step 422 and step 423 are executed.
In step 422, if a third response message returned by the first device according to the second response message is received before the timing means times out, the sending of the second response message is stopped when the third response message is received.
In step 423, if a third response message returned by the first device according to the second response message has not been received when the timing means times out, the sending of the second response message is stopped when the timing means times out.
In step 404, a chain scission operation is performed and the process ends.
In step 405, when the first acknowledgement message is not received, an operation of sending a link disconnection request message to the first device is performed in a next connection gap, and step 402 is performed.
In this embodiment, after sending the link disconnection request message to the first device, the second device monitors a message returned by the first device, and after monitoring the first response message sent by the first device, sends the second response message to the first device N times, and then performs the link disconnection operation, so that both the first device and the second device can perform the link disconnection operation in time, the bluetooth link communication portions of the first device and the second device are prevented from being blocked for a period of time, and the user experience is optimized.
