It should be noted that, for the following drawings describing the display interface, the drawings are only used for exemplarily describing one possible expression form of the display interface, and are not intended to limit that the actual product must adopt the same expression form.

The embodiment of the application provides a method for selecting Bluetooth equipment, after a terminal is successfully paired with at least two Bluetooth equipment and is in a connection maintaining state, the terminal can acquire the electric quantity and equipment information of the Bluetooth equipment, and the terminal can use the Bluetooth equipment to perform business according to the type of a trigger event, the electric quantity and the equipment information of the Bluetooth equipment and the like.

Referring to fig. 4, a method for selecting a bluetooth device according to an embodiment of the present application may include steps S101 to S103:

s101, the terminal is connected with at least two Bluetooth devices.

The connection between the terminal and the at least two Bluetooth devices means that the terminal and the at least two Bluetooth devices are successfully paired and are in a connection maintaining state.

A procedure of establishing a connection between a terminal and a bluetooth device will be described. In an alternative implementation, the terminal as a master device may page the bluetooth device as a slave device in a frequency hopping manner, the bluetooth device may scan for external pages at regular intervals, and in response to the page after scanning the page of the terminal, the terminal establishes an Asynchronous Connection-Less Link (ACL) Connection with the bluetooth device. After the ACL connection is established, the terminal may initiate establishment of a Logical Link Control and Adaptation Protocol (L2 CAP) connection, after the L2CAP connection is established, the terminal queries a hands-free Service of the bluetooth device through a Service Discovery Protocol (SDP) and obtains a channel number of a Radio Frequency Communication (RFCOMM), then the terminal initiates a connection request of the RFCOMM to establish an RFCOMM connection, and then the connection between the terminal and the bluetooth device is established.

S102, the terminal acquires the electric quantity and the equipment information of the at least two Bluetooth equipment connected with the terminal.

Specifically, the terminal may acquire the device information of the bluetooth device in an information interaction process of pairing with the bluetooth device. The device information of the bluetooth device may include the type, parameters, and bluetooth specifications supported by the bluetooth device. The device information is described in detail below.

The type of bluetooth device refers to the kind to which the bluetooth device belongs, which may belong to, for example, a mobile phone, a watch, a bracelet, an earphone, a stereo, a car, etc. The parameters of the bluetooth device may include, for example, audio parameters (sampling rate, coding format, etc.), monaural or binaural, stereo or mono. The device type and the parameter of the bluetooth device are used for indicating the privacy level or the sound effect level of the bluetooth device, specifically, the privacy level or the sound effect level can be distinguished according to the device type for the bluetooth devices of different types, and the privacy level or the sound effect level can be further distinguished according to the parameter for the bluetooth devices of the same type. For example, the privacy level of bluetooth headset will be higher than that of bluetooth car, the sound effect level of bluetooth car will be higher than that of bluetooth headset, and to the device that is the same as the headset, the sound effect level of ears will be higher than that of single ears, and so on. The privacy level is for the transmitted speech and the sound effect level is for the transmitted audio.

The terminal can actively acquire the electric quantity of the Bluetooth device by sending a query command to the Bluetooth device, or the Bluetooth device can periodically report the electric quantity to the terminal through an AT command defined in the HFP specification. The terminal actively acquires the electric quantity of the Bluetooth equipment, and the electric quantity can be generated at the moment of triggering any user event so as to meet the real-time property; the periodic reporting is used for refreshing the electric quantity of a certain bluetooth device at fixed time intervals, each bluetooth device can report at different time points, and the reporting periods can be the same or different.

For the bluetooth device supporting the A2DP specification, the power of the terminal can be periodically reported to the terminal through the AT command defined in the HFP specification, so that when the terminal transmits audio data to the bluetooth device through the A2DP channel, the power of the bluetooth device can still be acquired through the HFP channel.

S103, the terminal detects the current trigger event.

For example, if the terminal has an incoming call or an outgoing call or is in a call, the terminal system may detect a currently triggered event, for example, may detect and determine that the terminal performs a voice call service through a bottom layer interface or in another manner; or, if the terminal starts or is playing audio, the terminal may detect that the terminal performs an audio playing service.

S104, the terminal determines a first Bluetooth device from the at least two Bluetooth devices according to the type of the event, the electric quantity of the at least two Bluetooth devices and the device information.

The type of the event refers to a type to which the current event belongs, for example, if an interface of the terminal detecting the current event belongs to a voice call interface or an audio play interface, the type of the event belongs to a voice pass type or an audio play type, and the corresponding service is a voice call service or an audio play service. It can be understood that the type of the event is determined by detecting the interface of the current event, which is only an exemplary illustration, and other technical solutions may also be available, and the embodiment of the present invention does not limit this. The first bluetooth device refers to a bluetooth device through which the terminal will perform a voice call service or an audio play service, and is not limited to one bluetooth device, and may refer to at least one bluetooth device.

Specifically, referring to fig. 5, step S104 may include steps S1041-S1042:

s1041, if the electric quantity of more than one Bluetooth device in the at least two Bluetooth devices is larger than or equal to the threshold value and the specification required by the type is supported, the terminal determines the Bluetooth device with the highest priority as the first Bluetooth device from the more than one Bluetooth device.

As described in step S102, the device information may include the type, parameters, and bluetooth specification supported by the bluetooth device, and the device type and parameters of the bluetooth device are used to indicate the privacy level or sound effect level of the bluetooth device. If the type of the event is a voice call service, the required specification is a specification for transmitting voice, and the corresponding priority is a privacy level; if the type of the event is an audio playing service, the required specification is a specification for transmitting audio, and the corresponding priority is a sound effect level. The threshold may be a percentage representing the minimum amount of power normally used by the bluetooth device, and may be, for example, 50%. It should be noted that if only one bluetooth device has a power greater than or equal to the threshold and supports the specification required by the service, there is no priority problem and only the bluetooth device can be selected.

Through the step, the matching of the specification supported by the selected Bluetooth equipment and the service is ensured, the electric quantity of the selected Bluetooth equipment is ensured to meet the normal use, and the Bluetooth equipment with high priority is selected according to the service type.

S1042, if no electric quantity in the bluetooth devices supporting the specification required by the service is greater than or equal to the threshold value, the terminal determines the bluetooth device with the highest electric quantity as the first bluetooth device from the bluetooth devices supporting the specification required by the service.

Through the step, under the condition that the matching between the specification supported by the selected Bluetooth equipment and the service is ensured, if the electric quantity of all the Bluetooth equipment can not meet the normal use, the Bluetooth equipment with the highest electric quantity is selected as much as possible so as to ensure the data transmission as much as possible.

And S105, the terminal carries out the service corresponding to the event based on the first Bluetooth equipment.

The method comprises the following steps: and after the terminal determines the first Bluetooth equipment, the terminal performs a voice call service or an audio play service corresponding to the event.

The following describes steps S104 and S105 by way of example.

Referring to fig. 6, assuming that the user holds the terminal 200 by bluetooth to connect the bluetooth headset 602 and plays music (i.e., performs an audio playing service), the user enters a car having bluetooth 601 in the car and turns on the bluetooth 601 in the car. Because the vehicle-mounted bluetooth 601 is powered by a vehicle storage battery or a vehicle generator, theoretically, the vehicle-mounted bluetooth 601 is always full of electricity (which is equivalent to that the electricity of the vehicle-mounted bluetooth is always larger than a threshold value in the using process), the bluetooth headset is generally powered by a battery, and the electricity is lost in the using process. Assuming that the power of the bluetooth headset 602 is greater than the threshold, the bluetooth headset 602 and the vehicle bluetooth 601 both support the specification of transmitting voice and the specification of transmitting audio. The privacy level of the Bluetooth headset 602 is higher than that of the vehicle-mounted Bluetooth 601, and the sound effect level of the vehicle-mounted Bluetooth 601 is higher than that of the Bluetooth headset 602.

The terminal 200 is successfully paired with the vehicle-mounted Bluetooth 601 and connection is established. At this time, the terminal 200 learns that the connected bluetooth device is changed from the original connection with the bluetooth headset 602 to the connection with both the bluetooth headset 602 and the vehicle-mounted bluetooth 601, and evaluates whether to reselect the bluetooth device for the audio playing service. Specifically, the terminal 200 determines that the audio playing service is still performed after the connection of the vehicle bluetooth 601, according to the audio playing service being performed before the connection of the vehicle bluetooth 601. And the terminal determines the vehicle bluetooth 601 with the highest priority (the priority is the sound effect level for the audio playing service) as the first bluetooth device according to the specification that the bluetooth headset 602 and the vehicle bluetooth 601 both support the transmission audio and the electric quantity is larger than the threshold, and performs the audio playing service through the vehicle bluetooth 601. At this time, the device playing music is switched from the bluetooth headset 602 to the vehicle bluetooth 601, so that data can be ensured to be continuously transmitted (for example, the music is ensured to be continuously played), and a better bluetooth device (with better sound effect) is selected in combination with the special requirement of data.

If the terminal 200 suddenly receives an incoming call at this time or the user makes an outgoing call through the terminal 200, the terminal 200 again evaluates whether to reselect the bluetooth device for the voice call service. Specifically, the terminal 200 determines that a voice call service will be performed and stops transmitting audio according to incoming and outgoing calls. According to the specification that the bluetooth headset 602 and the vehicle-mounted bluetooth 601 both support the transmission voice and the power amount is greater than the threshold, the terminal 200 determines the bluetooth headset 602 with higher priority (the priority is the privacy level for the voice call service) as the first bluetooth device, and performs the voice call service through the bluetooth headset 602. At this time, the terminal stops playing music through the vehicle-mounted bluetooth 601, and performs voice call service through the bluetooth headset 602, so that normal transmission of data (for example, call is guaranteed) can be guaranteed, and a better bluetooth device (with better privacy) is selected in combination with special requirements of data.

It should be noted that, when the specification supporting the voice transmission is HFP and the terminal and the bluetooth device are in a connected state, if there is an incoming call and an outgoing call from the terminal, the terminal and the bluetooth device first establish a Service Level Connection (Service Level Connection), the terminal initiates a Codec Connection Setup (Codec Connection Setup) process, and finally, the terminal and the bluetooth device establish an audio Connection, so that the terminal can perform a voice call Service through the bluetooth device.

If the user stays on the bluetooth headset 602 for a long time, which results in the power level of the bluetooth headset 602 being below the threshold, the terminal 200 again evaluates whether to reselect the bluetooth device for the voice call service. Specifically, the terminal 200 determines to perform the voice call service according to the fact that the user still keeps calling. Although both the bluetooth headset 602 and the vehicle bluetooth 601 support the specification of the transmission voice, if the bluetooth headset 602 is continuously used for calling, the calling may be interrupted or the calling effect may be affected, so the terminal determines the vehicle bluetooth 601 as the first bluetooth device according to that only the vehicle bluetooth 601 supports the specification of the transmission voice and the power is greater than the threshold value, and performs the voice calling service through the vehicle bluetooth 601. At this time, the terminal stops performing the voice call service through the bluetooth headset 602, and performs the voice call service through the vehicle-mounted bluetooth 601, so that normal data transmission (for example, call guarantee) can be ensured. It should be noted that, if the user may also charge the bluetooth headset 602 through the onboard power supply during the voice call service of the terminal 200 through the onboard bluetooth 601, if the terminal detects that the power of the bluetooth headset 602 increases to be greater than the threshold value, it may be determined that the bluetooth headset 602 is again the first bluetooth device and the call is switched back to the bluetooth headset 602 again.

It should be noted that, when the specification supporting audio transmission is A2DP, and the terminal and the bluetooth device are in a connected state, if the terminal needs to perform an audio playing service through the bluetooth device, the terminal first establishes a stream endpoint on the bluetooth device through a stream endpoint discovery process, then configures information such as an audio channel and a sampling rate of the stream endpoint, and finally starts a stream, and the terminal can perform the audio playing service through the bluetooth device.

In addition, although the scenario listed in the embodiment of the present application takes as an example that one terminal connects two bluetooth devices at the same time and selects one bluetooth device from the two bluetooth devices, it is understood that the scenario is equally applicable to a scenario that one terminal connects more than two bluetooth devices at the same time and selects at least one bluetooth device from the two bluetooth devices.

Through the steps, the use of the Bluetooth equipment by the user is facilitated, the resources of different Bluetooth equipment are fully utilized, and the selection of the Bluetooth equipment is more intelligent and humanized. And the strategy of intelligently switching a plurality of connected Bluetooth devices is effectively provided, different logic strategies and priority algorithms are used according to different use scenes of users, and the usability is improved.

According to the method for selecting the Bluetooth equipment, the terminal selects at least one Bluetooth equipment from at least two Bluetooth equipments to perform business according to the type of the event to be triggered, the electric quantity of the Bluetooth equipment, the equipment information and the like, when the Bluetooth equipment is selected, the influence of different triggering events and the electric quantity of the Bluetooth equipment is considered, and the inconvenience in use caused by unreasonable Bluetooth equipment selection of the terminal is solved.

In order to enable a user to visually know the power condition of the currently connected or used Bluetooth device, the power of the Bluetooth device can be displayed on a display interface.

Optionally, in a possible implementation manner, referring to fig. 7, after the terminal is connected to at least two bluetooth devices, the method may further include step S201:

s201, the terminal displays the electric quantity of at least two connected Bluetooth devices on a display interface.

Specifically, the power display mode of the selected bluetooth device is different from the power display mode of the unselected bluetooth device.

Through the step, the terminal distinguishes which Bluetooth devices are used through different power display modes of the Bluetooth devices. The problem of common display of the electric quantities of different Bluetooth devices is effectively solved, and a user can more intuitively and clearly obtain the electric quantities of all connected Bluetooth devices.

For example, referring to fig. 8, as an example of displaying the power of the bluetooth device, the power of the bluetooth device connected to the terminal may be displayed on the terminal status bar, for example, a bluetooth icon 801, a power 802 of the bluetooth device 1, a power 803 of the bluetooth device 2, and a power 804 of the bluetooth device 3 may be displayed, and it can be seen from the figure that the power 802 of the bluetooth device 1 and the power 803 of the bluetooth device 2 are displayed in the same manner, which is a solid power representation manner, and the power 804 of the bluetooth device 3 is displayed in a different manner, which is an empty power representation manner. It can be used to indicate that the current bluetooth device 1 and the current bluetooth device 2 are the first bluetooth devices in the above steps, or that the current bluetooth device 3 is the first bluetooth device in the above steps. Of course, other electric quantity representation manners may be conceivable, for example, the electric quantity representation manners are distinguished by different colors, broken lines and solid lines, flashing and non-flashing, and detailed description is omitted.

In order to facilitate the user to know the situation of the currently connected or used bluetooth device, device information of the bluetooth device may also be displayed on the display interface.

Optionally, in a possible implementation manner, referring to fig. 9, after the terminal is connected to at least two bluetooth devices, the method may further include step S301:

s301, the terminal displays the device information of the connected at least two Bluetooth devices on a display interface.

Illustratively, referring to fig. 10, as another example of the power display of the bluetooth device, device information of the bluetooth device connected to the terminal may be displayed on the terminal status bar, and the displayed device information may be displayed in pair with the power. For example, a device type 805 of the bluetooth device 1, a device type 806 of the bluetooth device 2, and a device type 807 of the bluetooth device 3 may be displayed. Compared with the power representation mode in fig. 8, the user can know the selected bluetooth device more conveniently.

Illustratively, referring to fig. 11, for yet another example of the power display of the bluetooth device, the power and device information of the bluetooth device may also be displayed in the bluetooth sub-menu of the setup menu. One way to open the bluetooth submenu may be by clicking on a set up option, another way may be by a bluetooth icon 1101 in a drop down menu like that shown in fig. 11A. As shown in fig. 11B, more detailed and clear information may be displayed in the bluetooth submenu with respect to fig. 8 and 10, for example, the power 1102 of the bluetooth device, the device name 1103, the device type 1104, and the like may be displayed, and the selected bluetooth device and the unselected bluetooth device may be distinguished by different display manners of the power 1102 as well. When clicking on the bluetooth device shown in fig. 11B, all information of the bluetooth device, such as device name, custom name, MAC address, supported protocol, device type, device parameter, power, etc., as shown in fig. 11C may be further displayed.

During the continuous use process of the first Bluetooth device, the power of the first Bluetooth device may be too low, and at this time, the user may be reminded that the currently used Bluetooth device is low in power and/or automatically switched to other Bluetooth devices.

Optionally, in a possible implementation, referring to fig. 12, the method may further include steps S401 and S402:

s401, the terminal obtains the electric quantity of the first Bluetooth device.

The manner of acquiring the electric quantity of the bluetooth device refers to step S102, and details are not repeated.

S402, if the electric quantity of the first Bluetooth device is smaller than the threshold value, the terminal reminds the user and/or the terminal to switch to a second Bluetooth device to carry out the service.

The terminal may automatically switch to the second bluetooth device for the voice call service or the audio playing service according to the determination manner in step S104, where the second bluetooth device is a bluetooth device currently connected to the terminal, and may be a newly connected bluetooth device.

For example, referring to fig. 13, the terminal may prompt a message reminder of "current bluetooth device low battery" on the display interface. In addition, if the selection state of the Bluetooth equipment is changed, the terminal refreshes and displays the electric quantity of the at least two Bluetooth equipment on the display screen, so that the electric quantity display mode of the selected Bluetooth equipment is different from the electric quantity display mode of the unselected Bluetooth equipment.

The terminal can automatically select the Bluetooth equipment, selectable Bluetooth equipment and recommended Bluetooth equipment can be displayed on a display interface, and a user can manually select the Bluetooth equipment. And the priority of the setting information of the user for selecting the Bluetooth device is higher, and the Bluetooth device is preferentially selected according to the setting information of the user under the condition that the electric quantity of the Bluetooth device meets the normal use condition in the same scene. Illustratively, referring to fig. 14, assuming that a terminal 1401 located in a room a connects

bluetooth sound

1402 and 1403 located in the room a and bluetooth sound 1404 located in a room B, and that the

bluetooth sound

1402 and 1404 are the same model of bluetooth sound, the terminal 1401 may select these three bluetooth sounds at the same time when automatically selecting, but it is not necessary for the user to use the bluetooth sound 1404 located in the room B, and therefore it is possible for the user to set that the terminal 1401 selects only the

bluetooth sound

1402 and 1403 at this time, and even when the terminal 1401 restarts, the terminal 1401 still selects only the

bluetooth sound

1402 and 1403.

Optionally, in a possible implementation, referring to fig. 15, before step S105, the method may further include steps S501 to S502:

s501, displaying the alternative Bluetooth device and the recommended first Bluetooth device on a display interface by the terminal.

For example, referring to fig. 16A, a prompt message may be displayed within a certain time period when the terminal has determined that the first bluetooth device has not been switched, where the prompt message includes a recommended first bluetooth device "my car bluetooth" and an alternative bluetooth device "my headset" for reminding the user that the first bluetooth device "my car bluetooth" will be selected for a service if the user does not perform any operation. Optionally, the prompt message may include the power and device information of all bluetooth devices, so as to facilitate the user to make a selection. It should be noted that the terminal may also display the alternative bluetooth device and the recommended first bluetooth device in the setting interface shown in fig. 11B, and the display manner is not limited in the present application.

S502, the terminal receives the selection of the user and takes the Bluetooth device selected by the user as a first Bluetooth device.

For example, referring to fig. 16B, if the user does not want to switch music to bluetooth car 601, the user may click on my headset to select my headset and click on my bluetooth car to deselect my bluetooth car, the terminal still has my headset as the first bluetooth device, and the terminal does not switch music from bluetooth headset 602 to bluetooth car 601.

As for the setting information of the bluetooth device selected by the user with higher priority, the setting information of the user may be considered preferentially when selecting the bluetooth device, and further optionally, in a possible implementation manner, the step S104 may specifically include: the terminal can determine the first Bluetooth device from the at least two Bluetooth devices according to the type of the event, the electric quantity of the at least two Bluetooth devices, the device information and the setting information of the user. Specifically, referring to fig. 17, before step S1041, step S104 may further include step S1043:

s1043, if there is a Bluetooth device belonging to the setting information of the user, taking the Bluetooth device corresponding to the setting information of the user as a first Bluetooth device.

Through the steps, the matching of the specification supported by the selected Bluetooth equipment and the service is ensured, the electric quantity of the selected Bluetooth equipment is ensured to meet the normal use, and the preferred Bluetooth equipment of the user is optimized on the basis.

The preconditions of step S1041 now become: and in the at least two Bluetooth devices, more than one Bluetooth device has the electric quantity larger than or equal to the threshold value, supports the specification required by the type and does not have the Bluetooth device belonging to the setting information of the user.
