Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, 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.
All other embodiments, which can be derived by a person skilled in the art from the exemplary embodiments shown in the present application without inventive effort, shall fall within the scope of protection of the present application. Moreover, while the disclosure herein has been presented in terms of exemplary one or more examples, it is to be understood that each aspect of the disclosure can be utilized independently and separately from other aspects of the disclosure to provide a complete disclosure.
In the embodiments of the present application, the words "exemplary," "for example," and the like are used to mean serving as an example, instance, or illustration. Any embodiment or design described herein as "exemplary" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the term using examples is intended to present concepts in a concrete fashion.
Furthermore, the terms "comprises" and "comprising," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a product or device that comprises a list of elements is not necessarily limited to those elements explicitly listed, but may include other elements not expressly listed or inherent to such product or device.
The term "remote control" as used herein refers to a component of an electronic device (e.g., a bluetooth device as disclosed herein) that is typically wirelessly controllable over a relatively short range. Typically using infrared and/or Radio Frequency (RF) signals and/or bluetooth to connect with the electronic device, and may also include WiFi, wireless USB, bluetooth, motion sensor, etc. The term "new external device" is used only to distinguish "currently connected external device".
In the following embodiments, a bluetooth device refers to an electronic device including a bluetooth module, and through the bluetooth module, the bluetooth device may establish a bluetooth connection with other external devices supporting a bluetooth function. Since the external device is a device supporting the bluetooth function, the external device is also a bluetooth device. In some embodiments, the bluetooth device may further include a passive NFC tag or an active NFC tag, the bluetooth MAC address of the bluetooth device is stored in the NFC tag, after the external device with the NFC function and supporting the bluetooth function touches, the bluetooth device may be connected by taking the bluetooth MAC address, if the external device and the bluetooth device are not connected, the bluetooth device or the external device may initiate scanning pairing, the connection is established after pairing is successful, and after connection is successful, the function of the external device may be used or the external device may use the function of the bluetooth device.
After the traditional Bluetooth equipment is started, certain keys are required to be triggered again to enter a connectable mode, at the moment, the external equipment can search the Bluetooth equipment in a Bluetooth list and carry out pairing connection, and under the condition that pairing is not removed, both sides are started next time, and the external equipment can be connected back to continue to be used in a single mode. Generally, after the bluetooth device is connected, other external devices cannot be searched, because the bluetooth device is in an undiscoverable state.
The bluetooth device with the passive NFC tag needs to be connected to the external device, and the mode needs to be set to be discoverable first, and because the external device touches the passive NFC tag, the bluetooth device does not know, so the bluetooth device needs to be discoverable all the time. The Bluetooth device with the active NFC label only needs to be in a starting mode, and the external device can be connected by touching the NFC label.
After the Bluetooth device is started, the Bluetooth is set to be discoverable, and the Bluetooth name is set, so that the external device can be connected with the Bluetooth device, and the method comprises two methods:
1) opening the Bluetooth, entering a Bluetooth setting to search the Bluetooth of the Bluetooth equipment, and clicking connection;
2) and opening the external equipment NFC, and connecting the external equipment with the Bluetooth through touching the NFC label of the Bluetooth equipment.
In general, the connection procedure of bluetooth can be divided into:
ACL connection phase, namely Bluetooth link layer connection establishment phase. The Bluetooth device is connected by the external device for the first time, and at this stage, the Bluetooth device cannot acquire any other effective information except the MAC address of the external device.
2. And (5) a centering stage. At this stage the bluetooth device can access the device type of the external device (e.g. phone, headset, handle, etc.).
3. A paired stage. After the pairing is completed, the external device support profile type list can be acquired according to the uuids of the external device, and preparation is made for next profile connection.
Profile is in the connection phase. And establishing audio connection, wherein the profile represents that the external equipment has certain type of capability, and the connection is carried out according to the profile type.
Profile connected phase. After the connection is successful, the Bluetooth device can have corresponding functions, for example, after the A2dpSinkProfile is connected, the external device plays music and then sounds at the Bluetooth device.
The external device is connected for the first time through all stages 1-5, and the external device which is paired is connected again to be called back to be connected, and only three stages 1, 4 and 5 are needed. In order to achieve a better experience, the preemption speed must be fast enough, so the preemption timing needs to be as early as possible. The method and the device realize preemption in the stage 1 or the stage 2 by judging whether the device type of the external device can be acquired. And for the bluetooth equipment with active NFC label, the NFC module is with bluetooth equipment hardware connection, when external equipment touched the active NFC module of bluetooth equipment, bluetooth equipment can be informed the very first time, consequently can break off the external equipment of having connected at present in the very first time, in time release bluetooth bandwidth resource, other flows in addition do not have any difference, when bluetooth equipment detected external equipment NFC and touched promptly, if there is the external equipment of having connected, then direct disconnection, continue the connection of new external equipment.
Fig. 1 is a flowchart of a bluetooth preemption method for a bluetooth device according to an embodiment of the present application, and as shown in fig. 1, the bluetooth preemption method includes:
monitoring the Bluetooth device, illustratively, monitoring the Bluetooth connection establishing the external device, includes:
1) ACL connection stage, receive the already set up broadcast of the connection path (set up the connection path);
2) a pairing stage, wherein a pairing broadcast (pairing) is received;
3) a paired stage, receiving a paired broadcast (paired);
4) the profile is in the connection stage, and the audio connection is received and broadcast (the audio connection is being established);
5) profile connected phase, audio connection connected broadcast is received (audio connection established).
When the information touched by the active NFC is monitored, if the Bluetooth module has the currently connected external audio equipment, the Bluetooth module is controlled to disconnect the currently connected external audio equipment and establish the connection of new external equipment, and if not, the monitoring is continued; when the information sent by the Bluetooth module is monitored, whether the equipment type of the new external equipment can be acquired from the monitored information is judged, if the equipment type of the new external equipment is acquired and the Bluetooth module currently has the connected external equipment, the Bluetooth module is controlled to disconnect the currently connected external equipment and establish the connection of the new external equipment, and if not, the monitoring is continued.
In some embodiments, when the external devices are devices such as a remote controller and a keyboard, it is not desirable that the devices occupy limited bluetooth communication resources, and at this time, it is necessary to determine the device type of a new external device that wants to establish a new connection, and when the device type of the new external device is a preset type and the bluetooth module has a currently connected external device, the bluetooth module is controlled to disconnect the currently connected external device and establish a connection of the new external device; and when the device type of the new external device is not the preset type, continuing to monitor. For example, the bluetooth device may store a device type table locally, which is not limited in this application.
In some embodiments, if the bluetooth device is currently connected to only a non-audio device (such as a remote controller), and does not need to disconnect the non-audio device, the device type of the currently connected external device may be determined, and if the device type of the currently connected external device is only a non-audio device, the monitoring may be continued, otherwise, the bluetooth module is controlled to disconnect the currently connected external audio device, and a connection of a new external device is established.
In some embodiments, when the device type of the new external device is the same as the device type of the external device currently connected to the bluetooth module, the bluetooth module may be controlled to disconnect the currently connected external device and establish the connection of the new external device, otherwise, the monitoring is continued.
For example, a preemption instruction may be generated and sent to the bluetooth module to cause the bluetooth module to disconnect the currently connected external device, such as calling an A2dpSinkProfile disconnect interface. Meanwhile, the connection of the external equipment which is disconnected with the Bluetooth module at present and the new external equipment is established can be monitored. Illustratively, the process of disconnecting the currently connected external device includes:
1) calling an A2dpSinkProfile disconnect interface;
2) a2dp Sink Profile is in the disconnection stage, and the audio connection is disconnected and broadcast is received;
3) a2dp Sink Profile disconnected stage, receiving the audio connection disconnected broadcast;
4) ACL DISCONNECT phase, the broadcast is received that the connection path has been disconnected.
The embodiment of the present application further provides a bluetooth preemption device for a bluetooth device, where the device is used to implement the bluetooth preemption method according to any embodiment in fig. 1, and may be implemented by hardware, or may be implemented by hardware executing corresponding software. The hardware or software includes one or more units corresponding to the above-described functions, e.g., a listening unit, a preemption unit, etc.
The embodiment of the present application further provides a bluetooth device, which includes a bluetooth module and a preemption module communicatively connected to the bluetooth module, and the preemption module is configured to execute the method according to any embodiment in fig. 1.
The embodiment of the present application further provides a computer-readable storage medium, where the computer-readable storage medium stores computer instructions, and the computer instructions, when executed by a processor, implement the method according to any one of the embodiments in fig. 1.
The application of the bluetooth preemption method is further described below in conjunction with a specific embodiment. In this embodiment, the bluetooth device is a projection terminal with bluetooth sound function, and the external device is a mobile phone and an external bluetooth sound.
Originally, the projection end needs to enter the sound mode, and the mobile phone can search the Bluetooth sound of the projection end and connect the Bluetooth sound. Obviously, the passive NFC cannot provide such a trigger condition for projection, so the projection terminal needs to be specially modified, and needs to be capable of being connected with external bluetooth devices by scanning and being connected with mobile phone devices by searching. From the situation of the bluetooth protocol stack or the bluetooth bandwidth, it is obviously infeasible to connect the mobile phone to the projection end, and at this time, the projection end is also connected to the external audio. If the projection end is connected with the external Bluetooth sound equipment or the mobile phone is connected with the projection end sound equipment, the other mobile phone cannot be connected, because the strategy of the whole protocol stack does not support.
At this time, if the bluetooth preemption method of the embodiment of the application is utilized, when a new mobile phone wants to connect to the projection end, the ACL connection stage judges whether the device type can be acquired, if the device type cannot be acquired, the ACL connection stage ignores the device type, and if the device type can be acquired and is a phone type, the currently connected bluetooth device or mobile phone is disconnected. And in the binding stage, if the acquired type is a phone type, the currently connected Bluetooth device or mobile phone is disconnected. If the projection end is an active NFC projection end, the projection end detects NFC touch of the mobile phone, and at the moment, if the mobile phone or the Bluetooth sound box is connected, the connection is directly disconnected, and the connection of a new mobile phone is continued.
Because the bluetooth bandwidth is limited, in order to realize bluetooth preemption, bluetooth bandwidth equalization is required. For example, the usage scenario of bluetooth bandwidth includes:
1) keeping the stable connection of the Bluetooth remote controller;
2) the stable audio transmission of the connected mobile phone is ensured;
3) responding to the Page connection request of the new mobile phone.
Since audio transmission priority of the connected handset is higher, audio jamming can occur when reducing bandwidth occupation, so equalization adjustment from other two directions is modified as follows, for example:
1) the connection parameters of the Bluetooth remote controller are increased by 3-5ms, so that the requirement of the remote controller can be met, and the frequency of keeping connection and communication with the remote controller is reduced;
2) the interval time of Page Scan is shortened by 500-600ms, so as to respond the Page connection request of the new mobile phone more quickly.
