Detailed Description
As described in the background, existing BLE broadcast control schemes typically maintain BLE broadcast status continuously when connected objects need to connect to BLE channels. The connection scheme of the bluetooth headset comprising two headsets and the mobile phone is taken as an example for explanation, after one headset is connected with the other headset, a user needs to access the mobile phone, in order to enable the mobile phone to have the opportunity of accessing a BLE channel of the bluetooth headset, the bluetooth headset needs to continuously keep a BLE broadcasting state, radio frequency needs to keep working after the BLE broadcasting is started, and therefore power consumption of the bluetooth headset is increased. According to relevant bluetooth protocol, at BLE broadcast in-process, in order to accelerate connection speed, the interval (interval) of corresponding broadcast is very short, and later in order to reduce the consumption, the interval can grow, and then it is always open to correspond the broadcast, and the interval increases at the back, influences the connection experience of cell-phone easily. Considering the introduction of LE Audio BAP protocol to the broadcast interval, the first 30ms (millisecond) interval is recommended to be 20-30ms, and the later interval needs to be increased in order to reduce power consumption, and of course, the corresponding bluetooth protocol recommends that in order to improve the Connection experience, the relevant configuration can be performed according to other Connection Parameter Update procedures (such as Connection Parameter Update Procedure). However, even if various protocols are referred to and corresponding configuration measures are adopted, the conventional BLE broadcast control mode still easily causes large power consumption of corresponding bluetooth equipment.
In view of the above problems, the broadcast control method, the bluetooth audio system, and the bluetooth audio device provided in the present application control the broadcast of the second channel in combination with the pairing state between the bluetooth device and the connection object and the connection state between the first channel and the connection object of the bluetooth device in the corresponding pairing state, which is helpful to improve the reliability of the data transmission channel formed between the bluetooth device and the connection object. After the communication connection is established between the second channel of the Bluetooth device and the connection object, the broadcast of the second channel is closed in time, on the basis of ensuring the connection reliability, the power consumption generated by the broadcast of the second channel can be reduced, and the communication resources occupied by the broadcast of the second channel are saved; and when the second channel has overtime phenomena such as not accessing the connection object after the corresponding set time length, the broadcast of the second channel can be closed in time so as to save resources occupied by the broadcast of the second channel of the Bluetooth equipment. Thus, the resource consumption such as power consumption of the Bluetooth device can be reduced.
The technical solutions in the embodiments of the present application are clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application. The following embodiments and their technical features may be combined with each other without conflict.
The first aspect of the present application provides a broadcast control method, which is applied to bluetooth devices such as a bluetooth headset, a bluetooth lock, and/or a bluetooth sound. Referring to fig. 1, the broadcast control method includes S110 to S140.
S110, acquiring the pairing state between the Bluetooth device and the connection object.
The Bluetooth device can comprise Bluetooth audio devices such as a Bluetooth headset and other Bluetooth devices such as a Bluetooth lock. The states between the Bluetooth device and the connection object include various states such as unpaired states, paired states, connected states of the first channel of the Bluetooth device and the connection object, and the like. The connection object can comprise a smart device such as a mobile phone and/or a tablet computer and the like, which has a Bluetooth communication function and needs to transmit data to the blue device at least in part of the time period.
And S120, detecting the connection state between the first channel and the second channel of the Bluetooth device and a connection object respectively in the pairing state.
The first channel is a classic Bluetooth channel of the Bluetooth device, and the second channel is a BLE channel of the Bluetooth device. The bluetooth module corresponding to the first channel (i.e., the classic bluetooth channel) may refer to a bluetooth module supporting a bluetooth protocol below 4.0, which is also called a classic bluetooth module, and is generally used for transmission of a relatively large amount of data, and is widely applied to smart devices such as smart phones. The bluetooth module corresponding to the second channel (i.e. BLE channel) may refer to a module supporting the bluetooth protocol 4.0 or above, and is also referred to as BLE module, which has the advantages of low cost and low power consumption, and may be applied to various bluetooth devices with high real-time requirements.
For the second channel, the visibility (inquiry scan) and/or broadcast status of the second channel may be specifically controlled. Controlling the visibility and/or broadcast status of the second channel may include turning on the visibility of the second channel, turning on the broadcast of the second channel, and/or turning off the broadcast of the second channel.
And S130, if the Bluetooth equipment establishes communication connection with the connection object through the first channel, broadcasting is started on a second channel, and if the Bluetooth equipment establishes communication connection with the connection object on the second channel, broadcasting of the second channel is closed.
The Bluetooth device provided by the application is a dual-mode device and has a BLE function and a classic Bluetooth function simultaneously, so that the connection object transmits a part of data to the Bluetooth device through a second channel corresponding to the BLE function, for example, the part of data with small data volume and/or higher real-time requirement, so as to further improve the timeliness of the transmitted part of data, and the connection object can also transmit other data to the Bluetooth device through a first channel corresponding to the classic Bluetooth function, so as to ensure the stability of the other data in the transmission process. The control processes of the Bluetooth devices such as the dual-mode device on the classic Bluetooth module and the BLE Bluetooth module are mutually independent, and a first channel and a second channel can be simultaneously formed between the Bluetooth devices and corresponding connection objects respectively in a corresponding control mode, so that the connection objects can select the second channel and/or the first channel to transmit various data according to the characteristics of the connection objects needing to transmit data, and the real-time performance, the flexibility and the reliability in the Bluetooth communication process are improved.
The second channel may include a low power consumption channel, such as an LE Audio channel, for transmitting specific data, such as Audio data, or may include other bluetooth low energy channels.
According to the broadcast control method, the first channel and the second channel of the Bluetooth device are controlled to broadcast by combining the pairing state between the Bluetooth device and the connection object and the connection state between the first channel and the second channel of the Bluetooth device and the connection object under the corresponding pairing state, so that the reliability of a data transmission channel formed between the Bluetooth device and the connection object is improved; after the second channel is accessed to the connection object, the broadcast of the second channel is closed in time, on the basis of ensuring the connection reliability, the power consumption generated by the broadcast of the second channel can be reduced, and the communication resource occupied by the broadcast of the second channel is saved, so that the subsequent communication efficiency of the Bluetooth device is further improved.
In one embodiment, the broadcast of the second channel comprises a non-directional broadcast; if the bluetooth device is connected to the unpaired connection object, that is, the bluetooth device and the connection object are in an unpaired state, the broadcast control method further includes: and starting the visibility and the non-directional broadcast of the second channel so as to enable the unpaired connection object to identify the Bluetooth equipment and acquire the second channel, wherein the connection object has the opportunity of connecting the second channel, so that the connection object needing to be accessed can timely discover the Bluetooth equipment and connect the first channel and the second channel of the Bluetooth equipment.
For the bluetooth device, the unpaired connection object is usually a connection object which has not been connected to the corresponding bluetooth device before, and when the connection object of this kind is connected to the bluetooth device for the first time, it needs to be paired with the bluetooth device to ensure the accuracy of the connection process of the corresponding device. Optionally, for a bluetooth device such as a dual mode device, the pairing may be performed by using CTKD in the bluetooth protocol, that is, the pairing is performed by first connecting the second channel of the same bluetooth device and then connecting the first channel of the device. Optionally, the connection object may also be connected to the first channel of the bluetooth device first and then to the second channel of the bluetooth device, so as to ensure flexibility in the connection process of various channels.
In one example, after detecting connection states between the first channel and the second channel of the bluetooth device and a connection object, respectively, in the pairing state, the broadcast control method further includes: if the second channel does not access the connection object after exceeding the first set duration, the current pairing timeout can be judged, and the broadcast of the second channel is closed, so that resources occupied by the broadcast of the second channel of the Bluetooth device are saved, the Bluetooth device can enter the next pairing and/or connection work in time, and the effective utilization rate of the Bluetooth device is improved. Alternatively, the first set time period may be set according to the functional characteristics and/or performance characteristics of the bluetooth device, for example, a 10-second set time period parameter may be set.
Optionally, after the visibility and the unidirectional broadcast of the second channel are turned on, so that an unpaired connection object identifies the bluetooth device, and acquires the second channel, the control method may further include: if the first channel is accessed to the connection object and the second channel is not accessed to the connection object, the pairing with the connection object can be quitted, the non-directional broadcast is closed, and the directional broadcast to the corresponding connection object is opened, so that the corresponding connection object can obtain the corresponding second channel and be connected in time. If the second channel is accessed to the connection object, the broadcast of the second channel is closed to reduce the power consumption; and if the second channel does not access the connection object for more than the fourth set time, closing the broadcast of the second channel so as to enable the Bluetooth equipment to carry out the next round of connection work and the like.
In one embodiment, the broadcasting of the second channel includes directional broadcasting, and when the directional broadcasting is started, only the corresponding intelligent terminal can find the corresponding second channel, so that misconnection conditions that other currently invalid intelligent terminals access the second channel can be avoided. If the bluetooth device connects the paired connection object, that is, the bluetooth device and the connection object are in the paired state, at this time, the bluetooth device and the connection object do not need to be re-paired, and the connectivity (page scan) of the first channel can be opened, so that the connection object can connect the first channel. The broadcast control method further includes:
closing the visibility of the second channel, so that intelligent terminals such as other mobile phones and the like cannot find the second channel;
if the first channel is accessed to the connection object and the connection object supports the second channel, starting the directional broadcast of the second channel aiming at the connection object so as to enable the corresponding connection object to find the second channel and access in time.
Specifically, for the connected intelligent terminals, the local record of the bluetooth device or the information such as SDP (service discovery protocol) may record the configuration information of the intelligent terminals whether the intelligent terminals support BLE, so that the bluetooth device may obtain from the information such as the local record whether the intelligent terminals support the second channel, so as to control the broadcast of the second channel in a targeted manner, and improve the accuracy of the control process. Specifically, if the connection object supports the second channel, the directional broadcast of the second channel for the connection object is started, so that the connection object finds the second channel, and if the connection object does not support the second channel, the broadcast of the second channel does not need to be started, so as to avoid generating unnecessary resource consumption.
In one example, the bluetooth device includes a plurality of sub-devices, such as a bluetooth headset including left and right ear corresponding headsets, respectively. If the first channel accesses the connection object and the connection object supports the second channel, then starting the directional broadcast of the second channel for the connection object includes: if the first channel of one sub-device is accessed to the connection object and the connection object supports the second channel, the sub-device starts the directional broadcast of the second channel for the connection object and sends a private message for starting the directional broadcast to other sub-devices, so that the other sub-devices respectively start the directional broadcast of the corresponding second channel for the connection object, and thus the connection object can timely find the second channel respectively corresponding to each sub-device.
In one example, after detecting connection states between the first channel and the second channel of the bluetooth device and a connection object, respectively, in the pairing state, the broadcast control method further includes: if the second channel does not access the connection object for more than a second set time length, closing the broadcast of the second channel, and after a third set time length, returning to the step of starting the directional broadcast of the second channel for the connection object until the second channel is accessed to the connection object or the directional broadcast is started for a number of times greater than or equal to a first time threshold. The second set time period, the third set time period and/or the first time threshold may be set according to relevant protocol specifications, functional characteristics and/or performance characteristics of the bluetooth device, and the like, for example, the second set time period may be set to 1.28 seconds, the third set time period may be set to 1.28 seconds, the first time threshold may be set to 3 times, and the like.
In this embodiment, after a third set duration, the step of starting the directional broadcast of the second channel for the connection object is returned to be executed until the second channels are all accessed to the connection object, so that the bluetooth device can continuously start the directional broadcast for the paired connection objects for multiple times, multiple connection opportunities are provided for the connection object, the second channel corresponding to the connection object is prevented from being influenced by related accidental factors, and the reliability of connecting the second channel is improved. When the number of times that the bluetooth device starts the directional broadcast for the paired connection object is greater than or equal to the first time threshold, the corresponding second channel still does not access the corresponding connection object, which indicates that the connection object does not need to or is difficult to connect to the second channel currently, and at this time, the broadcast of the second channel can be closed, so as to reduce resources occupied by the broadcast of the second channel, or enable the bluetooth device to respond to other works.
In an example, if the first channel is a classic bluetooth channel and the second channel is an LE Audio channel, referring to fig. 2, the control process of the LE broadcast will be described with a pairing process between a mobile phone and a bluetooth headset, including:
s211, after the Bluetooth headset starts the visibility and the unidirectional broadcast corresponding to the LE Audio channel, the mobile phone and the Bluetooth headset enter into pairing;
s212, judging whether the classic Bluetooth channel is connected with the connection object, if so, executing the step S213;
s213, judging whether the LE Audio channel is connected with a connection object, if so, executing a step S214, otherwise, executing a step S215;
s214, quitting pairing and closing the unidirectional broadcast;
s215, quitting pairing, starting the directional broadcast, and starting a timer to judge that the timer is overtime when the starting of the directional broadcast exceeds a fourth set time length;
s216, judging whether the LE Audio channel is connected with a connection object, if so, executing a step S217, otherwise, executing a step S218;
s217, closing the directional broadcast;
s218, the timer times out, and step S217 is executed.
In one embodiment, if the first channel of the bluetooth device and the connection object are in a connected state, the broadcast control method further includes: and if the connection object supports the second channel, starting the directional broadcast of the second channel aiming at the connection object.
For some bluetooth devices, after the bluetooth devices are powered on, if a previously connected connection object exists in a current bluetooth communication range, a first channel of the bluetooth devices may automatically connect the connection object, and at this time, the bluetooth devices may obtain, from information, such as a local record, that records a configuration related to the connected devices, whether the connection device supports BLE, so as to determine whether the connection object supports the second channel. If the connection object supports the second channel, the directional broadcast aiming at the connection object is started so as to improve the accuracy of the started directional broadcast and enable the connection object to find the second channel of the Bluetooth device in time.
In one example, after detecting connection states between the first channel and the second channel of the bluetooth device and a connection object, respectively, in the pairing state, the broadcast control method further includes: if the second channel does not access the connection object accessed by the first channel for more than the fifth set time length, closing the broadcast of the second channel, and after the sixth set time length, returning to the step of starting the directional broadcast aiming at the connection object until the second channel is accessed to the connection object or the number of times of starting the directional broadcast is more than or equal to the second time threshold. The fifth setting time period, the sixth setting time period and/or the second time threshold may be set according to relevant protocol specifications, functional characteristics and/or performance characteristics of the bluetooth device, and the like, for example, the fifth setting time period may be set to 1.28 seconds, the sixth setting time period may be set to 1.28 seconds, the second time threshold may be set to 3 times, and the like.
The example can enable the Bluetooth device to continuously start the directional broadcast on the connection object connected with the first channel for multiple times, provide multiple connection opportunities of the second channel for the connection object, avoid the influence of relevant accidental factors on the connection object to connect the corresponding second channel, and improve the reliability of the connection of the second channel. When the number of times that the bluetooth device starts the directional broadcast for the paired connection object is greater than or equal to the second number threshold, the corresponding second channel still does not access the corresponding connection object, which indicates that the connection object does not need to or is difficult to connect to the second channel currently, and at this time, the broadcast of the second channel can be closed, so as to reduce the resources occupied by the broadcast of the second channel.
In an example, if the first channel is a classic bluetooth channel and the second channel is an LE Audio channel, referring to fig. 3, the control process of the LE broadcast will be described with reference to the LE Audio channel process between the mobile phone and the bluetooth headset, which includes:
s221, a classical Bluetooth channel of the Bluetooth headset is connected with a corresponding connection object, and the connection object supports LE Audio;
s222, the Bluetooth headset starts directional broadcasting aiming at a connection object;
s223, judging whether the LE Audio channel is connected with the connection object, if so, executing the step S214, otherwise, executing the step S215;
s224, closing the directional broadcast;
s225, timing a fifth set time length, closing BLE broadcast, and executing the step S226;
s226, and after the sixth set time period, determine whether the number of times of starting the directional broadcast is greater than or equal to the second time threshold, if so, execute step S224, otherwise, return to execute step S222.
Alternatively, if the bluetooth headset includes two headsets, namely a first headset and a second headset, and the steps S221 to S226 are performed by the first headset, as shown in fig. 3, after the first headset performs step S222, the following steps may be further performed: and S227, sending a private message for starting the directional broadcast to the second earphone so as to trigger the second earphone to start the directional broadcast for the corresponding connecting equipment.
In one embodiment, before detecting connection states between the first channel and the second channel of the bluetooth device and a connection object in the pairing state, the broadcast control method further includes: and starting the connectivity of the first channel so that the intelligent terminal needing to be connected with the first channel of the Bluetooth device can be connected with the first channel.
In one embodiment, the broadcast control method further comprises: if the connection object exits the pairing with the bluetooth device after connecting the bluetooth device (if the connection object has accessed the corresponding first channel and/or second channel), it indicates that the connection object does not need to connect the bluetooth device at that time, and the bluetooth device can close the broadcast of the second channel at this time, so as to save the resources occupied by the broadcast of the second channel, make the bluetooth device sleep in time, reduce the power consumption as much as possible, or make the bluetooth device respond to other work in time, so as to improve the utilization rate of the bluetooth device.
According to the broadcast control method, the first channel and the second channel of the Bluetooth device are respectively connected with the connection object in the corresponding pairing state by combining the pairing state between the Bluetooth device and the connection object, so that the broadcast of the second channel is controlled, and the reliability of a data transmission channel formed between the Bluetooth device and the connection object is improved; after the second channel is accessed to the connection object, the broadcast of the second channel is closed in time, on the basis of ensuring the connection reliability, the power consumption generated by the broadcast of the second channel can be reduced, and the communication resources occupied by the broadcast of the second channel are saved; and when the second channel has overtime phenomena such as not accessing the connection object for longer than the corresponding set time, the broadcast of the second channel is closed in time, and resources occupied by the broadcast of the second channel of the Bluetooth device are saved on the other hand. In addition, the broadcast of the second channel comprises directional broadcast, so that when the Bluetooth devices are paired or the first channel is accessed into the corresponding connection object, the directional broadcast can be started, the second channel of the Bluetooth devices can be found only by the corresponding connection object, the occurrence of misconnection conditions such as access of other invalid intelligent terminals into the second channel can be avoided, and the accuracy of the started broadcast of the second channel is improved.
