Description

External Bluetooth device classification display method and device and dual-hardware system display device

Technical Field

The present application relates to the field of bluetooth technologies, and in particular, to a method and an apparatus for displaying external bluetooth devices in a dual-hardware system display device in a classified manner, and a dual-hardware system display device.

Background

Currently, display devices may provide a user with a play picture such as audio, video, pictures, and the like. The dual-hardware system display device with the camera provided by the prior art can provide multifunctional experiences such as 'chatting while playing', 'chatting while watching', 'chatting while learning' for a user. For example, in a "chat while playing" scenario, real pictures of game participants are presented in real time while providing a game scenario for the user, in a "chat while watching" scenario, multiple video chat pictures are presented while playing a video program picture for the user, and so on.

As shown in fig. 3 or 4, the dual hardware system display device includes a first hardware system (a first chip) and a second hardware system (a second chip), and the first hardware system and the second hardware system may be connected, communicated, and powered through a plurality of different types of interfaces. In addition, each hardware system comprises a Bluetooth module. Respectively, the first hardware system comprises a first controller and various modules connected with the first controller through various interfaces, such as a first Bluetooth module, and the second hardware system comprises a second controller and various modules connected with the second controller through various interfaces, such as a second Bluetooth module. Through the first Bluetooth module and/or the second Bluetooth module, the first hardware system and/or the second hardware system can establish communication connection with the external Bluetooth device, so that a user can obtain richer experience on the display device by combining the functions of the external Bluetooth device. For example, using a bluetooth speaker, a bluetooth headset for a better audio input and output experience, using a bluetooth gamepad, etc. for a better gaming experience, and so on.

Detailed Description

To make the objects, technical solutions and advantages of the exemplary embodiments of the present application clearer, the technical solutions in the exemplary embodiments of the present application will be clearly and completely described below with reference to the drawings in the exemplary embodiments of the present application, and it is obvious that the described exemplary embodiments are only a part of the embodiments of the present application, but not all the embodiments.

For the convenience of users, various external device interfaces are usually provided on the display device to facilitate connection of different peripheral devices or cables to implement corresponding functions. When a high-definition camera is connected to an interface of the display device, if a hardware system of the display device does not have a hardware interface of a high-pixel camera receiving the source code, data received by the camera cannot be displayed on a display screen of the display device.

Furthermore, due to the hardware structure, the hardware system of the conventional display device only supports one path of hard decoding resources, and usually only supports video decoding with a resolution of 4K at most, so when a user wants to perform video chat while watching a network television, the user needs to use the hard decoding resources (usually GPU in the hardware system) to decode the network video without reducing the definition of the network video screen, and in this case, the user can only process the video chat screen by using a general-purpose processor (e.g. CPU) in the hardware system to perform soft decoding on the video.

The soft decoding is adopted to process the video chat picture, so that the data processing burden of a CPU (central processing unit) can be greatly increased, and when the data processing burden of the CPU is too heavy, the problem of picture blocking or unsmooth flow can occur. Further, due to the data processing capability of the CPU, when the CPU performs soft decoding on the video chat screen, multi-channel video calls cannot be generally implemented, and when a user wants to perform video chat with multiple other users in the same chat scene, access is blocked.

In view of the above aspects, to overcome the above drawbacks, the present application discloses a dual hardware system architecture to implement multiple channels of video chat data (at least one channel of local video).

The concept to which the present application relates will be first explained below with reference to the drawings. It should be noted that the following descriptions of the concepts are only for the purpose of facilitating understanding of the contents of the present application, and do not represent limitations on the scope of the present application.

Since the a-chip and the N-chip may have independent operating systems installed therein, there are two independent but interrelated subsystems in the display device 200. For example, Android and various APPs can be independently installed on the chip a and the chip N, so that each chip can realize a certain function, and the chip a and the chip N cooperatively realize a certain function.

The embodiment of the application provides a specific working scheme of double Bluetooth modules in double-hardware-system display equipment, which comprises scanning, display of scanning results and pairing.

Bluetooth (Bluetooth) is a wireless technology standard that enables short-range data exchange (using UHF radio waves in the ISM band of 2.4 to 2.485 GHz) between fixed devices, mobile devices, and building personal area networks. The frequency hopping is one of the most commonly used spread spectrum methods, and the operating principle thereof is a communication method in which the carrier frequencies of signals transmitted by both the transmitter and the receiver are discretely changed according to a predetermined rule, that is, the carrier frequencies used in the communication process are randomly hopped under the control of a pseudo-random change code.

The dual-hardware system display device comprises a first Bluetooth module and a second Bluetooth module, and the first hardware system and/or the second hardware system can establish communication connection with an external Bluetooth device through the first Bluetooth module and/or the second Bluetooth module, so that a user can obtain richer experience on the display device by combining the functions of the external Bluetooth device. For example, using a bluetooth speaker, a bluetooth headset for a better audio input and output experience, using a bluetooth gamepad, etc. for a better gaming experience, and so on.

Fig. 8 is a block diagram illustrating a dual bluetooth module framework in a dual hardware system display device according to an exemplary embodiment of the present application. As shown in fig. 8, the first application layer runs on the first hardware system, and the second application layer runs on the second hardware system. The first bluetooth module 810 may include a first Stack layer and first BT hardware connected with a first controller in a first hardware system; the second bluetooth module 820 may include a second Stack layer and second BT hardware connected with a second controller in a second hardware system. The Framework of the first Stack layer and the second Stack layer in the software layer is shown in fig. 8, wherein the Framework layer is responsible for processing the upper layer call logic and processing the report data of the Stack layer; the Stack layer is a Bluetooth protocol Stack, and a user processes the whole logic flow related to the Bluetooth module, including protocol judgment, filtering and the like; the BT hardware corresponds to a Controller, and is used to perform transmission/reception processing of the underlying device data.

As shown in fig. 8, the second bluetooth module may receive and respond to the instruction issued by the second application layer, and the first bluetooth module may receive and respond to the instruction issued by the first application layer. In addition, because the first hardware system and the second hardware system can be connected and communicated through a plurality of interfaces of different types, the first bluetooth module can also receive the instruction issued by the second application layer. Of course, in other scenarios, the second bluetooth module may also receive and respond to the instruction issued by the first application layer.

In the technical scenario of the application, the applications included in the first application layer are all third-party applications, such as game applications like "dance", "violent vehicle god", and the like; the second application layer includes a system setup application and other preset applications, where the other preset applications are typically display device brand side specific applications, such as social applications like "hi see" pre-installed in the hyxin television operating system.

The system setup application refers to a utility program for enabling a user to modify system configuration or functions, for example, the user modifies network connections including opening, closing, modifying connected networks, etc. in the system setup application, and for example, the user sets system parameters such as sound parameters, display parameters, etc. in the system setup application, and for example, the user manages various applications such as uninstallation, outage, etc. in the system setup application.

Typically, the application program may provide a user with a visual window for operating the bluetooth module and be presented through the display of the display device.

As an example, the user may operate the bluetooth module in a "system setup" application. Fig. 7b shows an operation interface provided by the "system setup" application, which is shown in fig. 7b, the operation interface is provided with operation controls such as "WI-FI", "universal setup", "bluetooth and peripheral", and after the user selects "bluetooth and peripheral" and determines it, the user enters another operation interface shown in fig. 7c, and when the user selects "scan device-OFF" and determines it, a scan instruction is triggered, and the scan instruction is used to instruct the first bluetooth module and the second bluetooth module to scan the external bluetooth device.

As shown in fig. 7b or fig. 7c, the external bluetooth device includes a bluetooth mouse 801, a bluetooth keyboard 802, a bluetooth speaker 803, a bluetooth game pad 804, and the like in the vicinity of the display device 200. These external bluetooth devices can send out broadcast information based on the frequency hopping principle after their bluetooth functions are turned on. When the Bluetooth module of the display device receives the broadcast information sent by any Bluetooth device, the device is scanned.

As another example, the user may operate the bluetooth module in an application program other than "system setup" in the second application layer. Fig. 9a shows an operation interface provided by such an application program, as shown in fig. 9a, the operation interface is provided with operation controls such as "premium class", "ranking", "bluetooth and speaker", and after the user selects "bluetooth and speaker" and determines it, the user enters another operation interface shown in fig. 9b, and when the user selects "scan device-OFF" and determines it, a scan instruction is triggered, and the scan instruction is used to instruct the second bluetooth module to scan the external bluetooth device.

As another example, a user may operate a bluetooth module in a third party application, such as a gaming application like "dance", "hobby car god", etc. Fig. 10a shows an operation interface provided by a certain game application, as shown in fig. 10a, after the user selects bluetooth and handle and confirms the selection, another operation interface shown in fig. 10b is entered, and when the user selects scanning device-OFF and confirms the selection, a scanning instruction is triggered, and the scanning instruction is used for instructing the first bluetooth module to scan the external bluetooth device.

Of course, in some other scenarios, when the application program is started, the scan instruction is automatically issued to the corresponding bluetooth module to instruct the corresponding bluetooth module to scan the external bluetooth device.

When the first bluetooth module or the second bluetooth module searches for the external bluetooth device, it needs to inquire on each channel, and when the inquirer and the external bluetooth device jump to the same channel at the same time, i.e. the inquirer scans the external bluetooth device, at this moment, the device information is recorded.

Based on the three scenes, if the first Bluetooth module and the second Bluetooth module receive the same scanning instruction, the first Bluetooth module and the second Bluetooth module both respond to the instruction and start to scan external Bluetooth equipment; if the first bluetooth module and the second bluetooth module receive different scanning instructions at the same time, the first bluetooth module and the second bluetooth module respectively respond to the received instructions and scan the external bluetooth device at the same time. Wherein the aforementioned "simultaneously" means that the two events occur at the same point in time or occur one after the other within a sufficiently short period of time.

Because the actual physical distance of first bluetooth module and second bluetooth module is very close, when the two scans outside bluetooth equipment simultaneously, very easily cause the interference each other, and then cause the phenomenon that scanning speed is slow, consuming time is long or can't scan equipment, seriously influence user experience.

The inventor finds that, when the problem that the two bluetooth modules interfere with each other in the display device is solved, due to the difference of the application programs run by the first hardware system and the second hardware system, the types of the bluetooth peripherals that different application programs need to be connected to have specificity, that is, different types of bluetooth peripherals need to be connected to different bluetooth modules. For example, since the third-party game application runs on the first hardware system, BLE-type devices such as a bluetooth keyboard, a bluetooth mouse, and a bluetooth gamepad need to be connected to the first bluetooth module; since the second hardware system includes audio input and output modules, bluetooth devices of the type A2DP, such as bluetooth speakers, bluetooth headsets, etc., need to be connected to the second bluetooth module.

Based on the above findings, the present application provides a method for a dual hardware system display device to scan an external bluetooth device, where the basic idea is to encapsulate different device type information in a scan command according to the difference of scan command initiators (a first application layer and a second application layer), so that when any bluetooth module receives the scan command, it scans the bluetooth devices of corresponding types according to the device type information carried in the scan command, and then two modules scan different types of bluetooth devices, thereby avoiding or reducing interference.

The following describes a specific implementation manner of the method for scanning the external bluetooth device by the dual hardware system display device according to the present application in detail. Since the first hardware system and the second hardware system both include a bluetooth chip, when a scan instruction is generated on an application program run by the first hardware system or a scan instruction is generated on an application program run by the second hardware system, how to distribute the generated instructions to the two bluetooth modules mainly includes the following three cases.

For the application program operated by the first hardware system, because the application program only comprises third-party application, especially game application, and has the requirement of connecting the Bluetooth peripheral, when the user triggers the operation of instructing to scan the external Bluetooth device on the application program operated by the first hardware system, the first application layer responds to the user operation, generates a scanning instruction and sends the scanning instruction to the first Bluetooth module, and the first Bluetooth module executes the scanning instruction without sending the scanning instruction to the second Bluetooth module, so as to save communication resources.

And the application program run by the second hardware system not only comprises a part of common user application, but also comprises system setting application. The user can operate the bluetooth module in the system setup application, including turning on bluetooth to search for surrounding devices, pairing with the searched devices, and turning off bluetooth, etc., and since it is not specified on which application the user will use the bluetooth peripheral, the scan instruction should be distributed to both bluetooth modules at the same time.

Specifically, when the user triggers an operation instructing scanning of the external bluetooth device on an application program running on the second hardware system, the second application layer generates a scanning instruction in response to the user operation, and sends the scanning instruction to the second bluetooth module and the first bluetooth module simultaneously if the application program is a system setting application, and sends the scanning instruction only to the second bluetooth module if the application program is another user application other than the system setting application.

As can be seen, in the embodiment of the present application, the scan instruction received by the first bluetooth module is generated and sent by an application program run by the first hardware system or a system setting application run by the second hardware system; the scan instruction received by the second bluetooth module is generated and sent by the system setting application and the other application programs run by the second hardware system.

In addition, in this embodiment, the scan command carries device type information, that is, information indicating the type of the bluetooth device. Because the first and second hardware systems run different applications, and the types of bluetooth peripherals that different applications need to connect to are also specific, that is, different types of bluetooth peripherals need to connect to different bluetooth modules, the device type information carried in a certain scanning instruction depends on the initiator of the scanning instruction.

For example, since most of the applications run by the first hardware system are third-party game applications that have a need to connect a bluetooth peripheral, BLE type information may be encapsulated in a scan instruction initiated by such applications to instruct the first bluetooth module to scan only BLE type bluetooth devices.

For another example, since the sound input/output module is included in the second hardware system, and of the applications run by the second hardware system, most of the social applications like "hi" have a need to connect a bluetooth peripheral in addition to the system setup application, the A2DP type information may be encapsulated in a scan instruction initiated by such an application to instruct the second bluetooth module to scan only the A2DP type of bluetooth device.

It should be noted that BLE (bluetooth Low Energy) is a short-range, Low-cost, and interoperable wireless technology that utilizes many intelligent means to minimize power consumption. As is well known to those skilled in the art, the LE bluetooth under the bluetooth 4.0 specification is referred to in the art as bluetooth low energy, while the present application relates to bluetooth devices of the BLE type, i.e. bluetooth devices supporting bluetooth low energy technology, such as a gamepad, a keyboard, a mouse, etc. The bluetooth device of A2DP (Advanced Audio Distribution Profile, bluetooth Audio transmission model protocol) type refers to a bluetooth device supporting the bluetooth Audio transmission model protocol, such as a bluetooth speaker, a bluetooth headset, etc.

Fig. 11 is a flowchart of an embodiment of a method for a dual hardware system display device to scan an external bluetooth device according to the present application, and as shown in fig. 11, the method may include:

in step 111, in response to an operation triggered by an application running on the first hardware system by a user and used for instructing to scan an external bluetooth device, a scan instruction carrying BLE type information is generated and sent to the first bluetooth module.

Or in step 112, in response to an operation triggered by the user on the system setting application running in the second hardware system and used for instructing to scan the external bluetooth device, generating a scanning instruction carrying information corresponding to all types, and sending the scanning instruction to the first bluetooth module and the second bluetooth module.

Or in step 113, in response to an operation, triggered by the user, on an application program, running on the second hardware system, other than the system setting application, for instructing to scan the external bluetooth device, a scan instruction carrying information of the A2DP type is generated and sent to the second bluetooth module.

In the specific implementation of step 111-113, the fields indicating the BLE type, the A2DP type, or all types may be encapsulated in the data packet of the scan instruction, and sent to the corresponding bluetooth module, the protocol stack of the corresponding bluetooth module determines, according to the device type information carried in the scan instruction, that the device type to be scanned is all types of BLE or A2DP, and then the device type is scanned by the BT hardware layer.

In step 114, when the first bluetooth module receives the scan command carrying the device type information, the first bluetooth module scans the bluetooth devices of corresponding types according to the carried device type information.

Specifically, as shown in fig. 12, in step 121, when the first bluetooth module receives a scan instruction carrying device type information, the first bluetooth module determines a device type to be scanned according to the carried device type information.

In step 122, if the first bluetooth module determines that the carried device types correspond to all types, all types of bluetooth devices are scanned.

In step 123, if the first bluetooth module determines that the carried device type corresponds to a BLE type, scanning for a bluetooth device of the BLE type.

Therefore, when the first Bluetooth module receives the scanning instruction, the type of the equipment to be scanned is judged according to the equipment type information carried in the scanning instruction, if the equipment is of the BLE type, the Bluetooth equipment of the BLE type only needs to be scanned, and if the equipment is of all types, the Bluetooth equipment of all types is scanned, so that the first Bluetooth module only scans the equipment of the BLE type when responding to part of the scanning instruction, and the interference between the first Bluetooth module and the second Bluetooth module is reduced.

In step 115, when the second bluetooth module receives the scan command carrying the device type information, the second bluetooth module scans the bluetooth device of the type corresponding to the device type information in advance according to the carried device type information.

In the embodiment of the present application, in a protocol stack of the first bluetooth module, a correspondence between device type information carried in a scan instruction and a device type to be actually scanned is preset. In the preset corresponding relation, if the device types carried in the scanning instruction are all types, the BR and EDR types are corresponding, and if the device types carried in the scanning instruction are A2DP types, the A2DP types are corresponding, so that even if the second bluetooth module receives the scanning instruction for instructing the second bluetooth module to scan all types of devices, only the BR and EDR types of devices are scanned, and the interference between the second bluetooth module and the first bluetooth module is reduced as much as possible.

Wherein, an EDR (Enhanced Data Rate, bluetooth Enhanced Rate technology) type bluetooth device refers to a bluetooth device supporting the bluetooth Enhanced Rate technology; a BR (Basic Rate) type bluetooth device refers to a bluetooth device supporting bluetooth Basic logging. BR and EDR are well known to those skilled in the art and are not described in detail herein.

As shown in fig. 13, step 115 may specifically include:

step 131, when the second bluetooth module receives the scan command of the carried device type information, the second bluetooth module determines whether the carried device type information corresponds to all types.

Step 132, if the second bluetooth module determines that the carried device types correspond to all types, scanning BR and EDR type bluetooth devices;

step 133, if the second bluetooth module determines that the carried device type corresponds to the A2DP type, scanning the bluetooth device of the A2DP type.

Therefore, when the second bluetooth module receives the scanning instruction, the type of the device to be scanned is judged according to the device type information carried in the scanning instruction, if the device is of the A2DP type, the device of the A2DP type only needs to be scanned, and if the device is of all types, the device of the BR and EDR types only needs to be scanned, so that the second bluetooth module only scans the device of the specific type when responding to the scanning instruction, and the interference between the second bluetooth module and the first bluetooth module is reduced.

According to the technical scheme, in the method for scanning the external Bluetooth device in the dual-hardware system display device, when the first Bluetooth module receives the scanning instruction carrying the device type information, the first Bluetooth module scans the Bluetooth device of the corresponding type according to the carried device type information; when the second Bluetooth module receives a scanning instruction carrying equipment type information, the second Bluetooth module scans Bluetooth equipment of a type corresponding to the equipment type information in advance according to the carried equipment type information. Because the first bluetooth module and the second bluetooth module respectively scan corresponding bluetooth devices according to the device type information carried in the scanning instruction, rather than scanning all types of bluetooth devices at the same time, the mutual interference can be avoided or reduced in the case of simultaneously responding to the same or different scanning instructions.

Through this application embodiment, in the scanning scene of difference, all can reach the effect of jam-proof, specific:

in the scene (1), the first bluetooth module and the second bluetooth module receive different scanning instructions at the same time, respectively, the first bluetooth module receives the scanning instruction sent by the application program operated by the first hardware system, and the second bluetooth module receives the scanning instruction sent by the application program operated by the second hardware system except for the system setting application. In this scenario, the first bluetooth module will scan for bluetooth devices of BLE type, while the second bluetooth module will scan for bluetooth devices of A2DP type, so even if both bluetooth modules perform scanning actions simultaneously, no interference will occur.

In the scenario (2), the first bluetooth module and the second bluetooth module receive the same scanning instruction at the same time, that is, the scanning instruction sent by the system setting application operated by the second hardware system. In this scenario, the first bluetooth module will scan for all types of bluetooth devices, while the second bluetooth module will only scan for BR and EDR type bluetooth devices, thus greatly reducing mutual interference even though both bluetooth modules are scanning at the same time, since not all types of devices are being scanned.

Therefore, the method for scanning the external Bluetooth device in the dual-hardware system display device can avoid or greatly reduce interference aiming at the situation that two Bluetooth modules perform scanning actions simultaneously.

In a further embodiment, the control means of the display device has, in addition to the infrared module, a bluetooth module, such as a bluetooth remote control. After the Bluetooth remote controller is successfully paired with the display equipment, data interaction can be carried out on the Bluetooth remote controller and the display equipment so as to control the display equipment. Therefore, the method for scanning the external bluetooth device in the dual hardware system display device of the present application may further include: after the dual-hardware-system display device is started, the second Bluetooth module continuously scans the Bluetooth remote controller until the second Bluetooth module is successfully matched with the Bluetooth remote controller or receives a pause instruction, wherein the pause instruction is used for indicating the second Bluetooth module to stop scanning the Bluetooth remote controller.

It should be noted that, during the process of interactively pairing the display device and the bluetooth remote controller, the data packet sent by the bluetooth remote controller is loaded with the identification information of the bluetooth remote controller, such as the field "? Hisense #? And the display equipment identifies the Bluetooth remote controller according to the identification information to realize the pairing connection with the Bluetooth remote controller.

It should be further noted that, during the interactive pairing process between the display device and the bluetooth remote controller, the second bluetooth module continues to actively scan until the pairing is successful, or until the passive stop is performed, such as receiving a pause instruction for instructing the second bluetooth module to stop actively scanning the bluetooth remote controller.

Since the BT hardware layer of the second bluetooth module may be in a state of actively scanning the bluetooth remote controller at any time, in order to avoid a scan instruction issued by the first application layer of the BT hardware layer, in another embodiment, before the second bluetooth module scans the bluetooth device of the A2DP type or the bluetooth devices of the BR and EDR types according to the carried device type information, the method of this embodiment further includes:

judging whether a BT hardware layer of the second Bluetooth module scans the Bluetooth remote controller or not;

and if so, stopping scanning the Bluetooth remote controller to execute the scanning instruction.

In the hardware system of any intelligent device such as display equipment, terminal equipment and the like, the Bluetooth module can feed back the scanned equipment information to the application layer from the BT hardware layer at the bottom layer upwards in real time, and the application layer displays the equipment identification in the equipment information, such as the self-defined name of the equipment, the MAC address of the equipment and the like. In specific implementation, the application layer may generate an equipment list according to the equipment information reported by the bluetooth module, and add the equipment identifier to the equipment list for display.

Under the dual bluetooth module configuration of the dual hardware system display device shown in fig. 8, the first bluetooth module and the second bluetooth module inevitably respond to the same or different scan commands at the same time, so that the external bluetooth device is scanned at the same time. In this case, the display device will present the scanning results of the first bluetooth module and the second bluetooth module at the same time, resulting in repeated display of information of the same bluetooth device in the list, which is not only easy to confuse for the user and difficult to select a device to be connected, but also when the user triggers an instruction to pair with a certain device displayed in the list, the system cannot determine to which bluetooth module the instruction should be sent, resulting in easy connection of the specified device to the wrong bluetooth module.

As an example, fig. 14 shows an operation interface provided by a system setup application run by the second hardware system, and as shown in fig. 14, in the operation interface, the external bluetooth devices "a" and "C" are repeatedly displayed in the list, which is caused by the fact that the first bluetooth module and the second bluetooth module report device information about the bluetooth devices "a" and "C".

When the situation shown in fig. 14 occurs, on the first hand, it brings trouble that it is impossible to judge whether "a" and "a" are the same device or different devices to the user, and on the second hand, when the user selects one of "a" to instruct the display device to pair with the bluetooth device "a", the application layer cannot determine to which bluetooth module an instruction indicating pairing should be sent, thereby easily causing the bluetooth device "a" to connect to the wrong bluetooth module.

In order to solve the above problems, the inventors have found that, due to the difference between the applications run by the first and second hardware systems, the types of bluetooth peripherals that different applications need to be connected to have specificity, that is, different types of bluetooth peripherals need to be connected to different bluetooth modules. Based on the discovery, the application provides a classified display method for external Bluetooth devices of a dual-hardware system display device, and the basic idea is to separate and display device information reported by dual Bluetooth modules in a classified manner.

Fig. 15 is a flowchart of an embodiment of a method for displaying external bluetooth devices of a dual hardware system display device according to the present application, where as shown in fig. 15, the method may include:

step 151, receiving device information sent by the first bluetooth module or the second bluetooth module, where the device information includes a device type and a device identifier of the bluetooth device scanned by the first bluetooth module or the second bluetooth module.

In one scenario, a user triggers an operation of instructing a display device to scan an external bluetooth device on a system setting application running in a second hardware system, the system setting application responds to the user operation to generate a scanning instruction and sends the scanning instruction to a first bluetooth module and a second bluetooth module, the first bluetooth module and the second bluetooth module receive the scanning instruction and respectively scan all types of bluetooth devices, device information is recorded, and the scanned device information is respectively sent to the system setting application.

It should be noted that, because the system setting application runs on the second hardware system, and the first bluetooth module belongs to the first hardware system, the first bluetooth module may send the device information to the second hardware system according to the following steps:

firstly, a first Bluetooth module sends device information to an RPC (Remote Procedure Call) APP, wherein the RPC APP runs in a first hardware system; then, the RPC APP is used for sending the equipment information of the first Bluetooth module to a second hardware system.

The Device information includes a Device type and a Device identifier of the bluetooth Device scanned by the first bluetooth module or the second bluetooth module, where the Device type includes the aforementioned A2DP type, and in addition, in this embodiment, the Device information further includes a Device of an HID (Human Interface Device) type, such as a standard bluetooth keyboard, a bluetooth mouse, a bluetooth game pad, and the like.

In addition, the device information also includes a sending end identifier, so that the system setting application can judge which bluetooth module reports the received device information. For example, the identification information of the first bluetooth module is packaged in the device information sent by the first bluetooth module, and the identification information of the second bluetooth module is packaged in the device information sent by the second bluetooth module.

Optionally, the system setting application analyzes the received device information to obtain the device type, the device identifier, and the sender identifier information. And judging whether the sending end of the scanning information is the first Bluetooth module or the second Bluetooth module according to the identification information of the sending end, and judging whether the equipment type is HID or A2 DP. If the device information is sent by the first bluetooth module and the device type is HID, go to step 152, and if the device information is sent by the second bluetooth module and the device type is A2DP, go to step 153.

In step 152, if the device information is sent by the first bluetooth module and the device type is HID, the device identifier is displayed in a first list.

Otherwise, if the device information is sent by the first Bluetooth module and the device type is not HID, discarding the device information.

Therefore, the device information reported by the first bluetooth module is filtered through step 152, and only the information of the HID device is retained and displayed.

In step 153, if the device information is sent by the second bluetooth module and the device type is A2DP, the device identifier is displayed in a second list.

On the contrary, if the device information is sent by the second Bluetooth module and the device type is not A2DP, the device information is discarded.

Therefore, the reported device information of the second bluetooth module is filtered in step 153, and only the information of the A2 DP-class device is reserved and displayed.

In the specific implementation, when equipment information which is sent by a first Bluetooth module and has the equipment type of HID is received for the first time, a first list is generated according to equipment identification in the equipment information and is displayed on a user operation interface; when equipment information which is sent by a second Bluetooth module and has the equipment type of A2DP is received for the first time, a second list is generated according to the equipment identification in the equipment information and is displayed on a user operation interface; and updating the first list or the second list according to the specific content of the subsequently received device information.

Fig. 16 is a user interface provided by a system setup application according to an exemplary embodiment of the present application, in which a first list and a second list are presented.

According to the technical scheme, in the external Bluetooth device classification display method for the dual-hardware system display device, the device information sent by the first Bluetooth module or the second Bluetooth module is received, wherein the device information comprises the device type and the device identification of the Bluetooth device scanned by the first Bluetooth module or the second Bluetooth module; if the equipment information is sent by the first Bluetooth module and the equipment type is HID, displaying the equipment identification in a first list; if the device information is sent by the second bluetooth module and the device type is A2DP, the device identification is displayed in a second list.

In another embodiment, the method for displaying the external bluetooth device in a classified manner for the dual-hardware system display device further includes:

step 154, receiving a pairing instruction input by the user according to the first list or the second list, wherein the pairing instruction comprises a target device identifier selected by the user from the first list or the second list. In addition, the pairing instruction further comprises pairing key information used for carrying out trust authentication with the target device.

As an example, fig. 17 shows an interaction diagram when a user inputs a pairing instruction according to the first list or the second list. As shown in fig. 17, the display device presents an operation interface provided by the system setup application, where the operation interface includes a first list and a second list, the first list includes HID type bluetooth devices scanned by the plurality of first bluetooth modules, and the second list includes A2DP type bluetooth devices scanned by the plurality of second bluetooth modules. And the user selects the Bluetooth device 'B' in the first list on the operation interface by using the control device, the Bluetooth device 'B' is the target device, and the Bluetooth device 'B' is the target device identifier.

In the scenario shown in fig. 17, the system configuration application will respond to the user operation to generate a pairing instruction including the target device identifier, and determine whether the list of the target device identifier is the first list or the second list. If the list is the first list, step 155 is executed, and if the list is the second list, step 156 is executed.

In step 155, if the target device identifier belongs to the first list, the pairing instruction is sent to the first bluetooth module.

If the target device identification belongs to the first list, the target device is scanned by the first Bluetooth module, and therefore the pairing instruction is sent to the first Bluetooth module so that the target device and the target device can be in pairing connection.

In step 156, if the target device identifier belongs to the second list, the pairing instruction is sent to a second bluetooth module.

If the target device identification belongs to the second list, the target device is scanned by the second Bluetooth module, and therefore the pairing instruction is sent to the second Bluetooth module so that the target device and the target device can be in pairing connection.

In addition, after the first bluetooth module or the second bluetooth module is successfully paired with the target device, pairing response information including the target device identifier is sent to the application layer. Therefore, the method of this embodiment further includes receiving pairing response information sent by the first bluetooth module or the second bluetooth module, and determining whether a list to which a target device identifier included in the pairing response information belongs is a first list or a second list, if the list is the first list, adding a pairing flag to the target device identifier in the first list, and if the list is the second list, adding a pairing flag to the target device identifier in the second list, so as to indicate that the device corresponding to the target device identifier is paired.

Therefore, the step 151 and the step 156 provided by the present application can not only avoid the repeated display of the same device, thereby avoiding the trouble for the user, but also avoid the situation that the bluetooth device is connected to the wrong bluetooth module, thereby avoiding the problem that the connected bluetooth device is unavailable.

Based on the method embodiments shown in fig. 15 to 17, in some scenarios, if the first bluetooth module does not scan the HID device and/or the second bluetooth module does not scan the A2DP device, the first list and/or the second list may be empty, which may cause the user to misunderstand that the bluetooth module of the display device is faulty. However, in practice, the fact that the first list and/or the second list are empty may be caused by discarding the non-HID class device scanned by the first bluetooth module and/or the non-A2 DP class device scanned by the second bluetooth module.

In order to avoid the above phenomenon causing the error of the bluetooth module failure to the user, in another embodiment, after step 151, the method for scanning the external bluetooth device in the dual hardware system display device further includes:

step 181, determining whether the sending end of the device information is a first bluetooth module or a second bluetooth module; if the bluetooth module is the first bluetooth module, step 182 is executed, and if the bluetooth module is the second bluetooth module, step 183 is executed.

In step 182, if the device information is sent by the first bluetooth module, the device identifier is displayed in a third list.

In step 183, if the device information is sent by the second bluetooth module, the device identifier is displayed in a fourth list.

Because the total number of all types of Bluetooth devices scanned by the first Bluetooth module is presented in the third list, and the total number of all types of Bluetooth devices scanned by the second Bluetooth module is also presented in the fourth category, whether the user or the display device is empty or not can be judged whether the first Bluetooth module is in fault or not through the third list, and whether the second Bluetooth module is in fault or not can be judged through the fourth list or not.

Specifically, if the first list is empty and the third list is not empty, it indicates that the first bluetooth module is working normally; and if the second list is empty and the fourth list is not empty, the second Bluetooth module works normally.

In the embodiments shown in fig. 14 to 18, in order to avoid the trouble caused by the repeated display of the same device to the user and avoid the problem that the target device is connected to the wrong bluetooth module and the connected bluetooth device is not available, the scanning information reported by the first and second bluetooth modules is filtered, classified and separately displayed in the application layer.

According to the above-mentioned external bluetooth device classification display embodiment of the dual hardware system display device, the present application further provides an external bluetooth device classification display apparatus of the dual hardware system display device, in the dual hardware system display device, the first hardware system includes a first bluetooth module, and the second hardware system includes a second bluetooth module. As shown in fig. 19, the classification display device includes:

a receiving module 191, configured to receive device information sent by a first bluetooth module or a second bluetooth module, where the device information includes a device type and a device identifier of a bluetooth device scanned by the first bluetooth module or the second bluetooth module; a first display module 192, configured to display the device identifier in a first list if the device information is sent by the first bluetooth module and the device type is HID; and if the device information is sent by the second Bluetooth module and the device type is A2DP, displaying the device identification in a second list.

Further, the first display module is further configured to: if the equipment information is sent by the first Bluetooth module and the equipment type is not HID, discarding the equipment information; and if the device information is sent by the second Bluetooth module and the device type is not A2DP, discarding the device information.

Further, the apparatus further comprises: the second display module is used for displaying the equipment identifier in a third list if the equipment information is sent by the first Bluetooth module; and if the equipment information is sent by the second Bluetooth module, displaying the equipment identification in a fourth list.

Further, the receiving module is further configured to: receiving pairing response information sent by a first Bluetooth module or a second Bluetooth module, wherein the pairing response information comprises a target device identifier; the first display module is further configured to add a pairing flag to the target device identifier in the first list if the target device identifier belongs to the first list, so as to indicate that the device corresponding to the target device identifier of the user is paired; and if the target equipment identification belongs to the second list, adding a pairing mark for the target equipment identification in the second list to indicate that the equipment corresponding to the target equipment identification of the user is paired.

In addition, the present application also provides a dual hardware system display device, including a first hardware system and a second hardware system, the first hardware system includes a first controller and a first bluetooth module connected to the first controller, the second hardware system includes a second controller and a second bluetooth module connected to the second controller, the second controller is configured to: receiving device information sent by a first Bluetooth module or a second Bluetooth module, wherein the device information comprises a device type and a device identification of a Bluetooth device scanned by the first Bluetooth module or the second Bluetooth module; if the equipment information is sent by a first Bluetooth module and the equipment type is HID, displaying the equipment identification in a first list; and if the device information is sent by the second Bluetooth module and the device type is A2DP, displaying the device identification in a second list.

In another embodiment, the second controller is further configured to perform some or all of the steps of the external bluetooth device classification display embodiment of the dual hardware system display device.

In order to solve the same problem, namely how to avoid display duplication and how to avoid the target device being connected to the wrong bluetooth module to achieve accurate pairing, the present application further provides another solution, specifically a method for accurately pairing a dual hardware system display device and an external bluetooth device, and a detailed description will be given below on a specific implementation method of the method.

Fig. 20 is a flowchart of an embodiment of a method for accurately pairing a dual hardware system display device and an external bluetooth device according to the present application, and for convenience of description, in this embodiment, the external bluetooth device is simply referred to as a bluetooth peripheral. As shown in fig. 20, the method may include:

step 201, receiving first device information and/or second device information.

The first device information is returned when the first Bluetooth module determines that the device type in the first device information is BLE, and the second device information is returned when the second Bluetooth module determines that the device type in the second device information is A2 DP.

In the embodiment of the application, when a user operates on an operation interface presented by the display device and instructs the display device to scan the bluetooth peripheral, a scanning instruction is generated, and the application layer of the display device issues the scanning instruction to the bottom layer. The bottom layer function module, such as the precise pairing device or module provided by the application, receives the scanning instruction, and sends the scanning instruction to the first bluetooth module and/or the second bluetooth module, so as to indicate the first bluetooth module and/or the second bluetooth module to acquire the device information of the bluetooth peripheral. The device information includes a device type, a device unique identifier, a device name, and the like. For convenience of distinction and explanation, in this embodiment, the device information acquired by the first bluetooth module is collectively referred to as first device information, and the device information acquired by the second bluetooth module is collectively referred to as second device information.

The scanning instruction comprises a first scanning instruction, a second scanning instruction and a third scanning instruction, and is characterized in that the first scanning instruction is initiated by an application program operated by a first hardware system, the second scanning instruction is initiated by a system setting application operated by a second hardware system, and the third scanning instruction is initiated by an application program operated by the second hardware system except the system setting application.

In the embodiment of the application, if a first scanning instruction is received, the first scanning instruction is sent to a first Bluetooth module; if a second scanning instruction is received, the second scanning instruction is sent to the first Bluetooth module and the second Bluetooth module at the same time; and if the third scanning instruction is received, sending the third scanning instruction to the second Bluetooth module.

When the first Bluetooth module receives the first scanning instruction or the second scanning instruction, responding to the instruction, and acquiring first equipment information of the Bluetooth peripheral equipment; and the protocol stack of the first Bluetooth module judges the type of the equipment in the first equipment information, if the equipment is BLE equipment, the first equipment information is returned, and if not, the first equipment information is discarded.

When the second Bluetooth module receives the second scanning instruction or the third scanning instruction, responding to the instruction and acquiring second equipment information of the Bluetooth peripheral equipment; and the protocol stack of the second Bluetooth module judges the device type in the second device information, if the device type is the A2DP type device, the second device information is returned, and otherwise, the second device information is discarded.

It can be seen that, with the implementation, the device scanned by the BT hardware layer is filtered in the protocol stack of the bluetooth module, and for the first bluetooth module, only the device information of the BLE device is reported, and for the second bluetooth module, only the device information of the A2DP device is reported.

Step 202, generating a device list according to the device identifier in the first device information and/or the second device information.

The device identification includes a unique identification such as a media access control address (MAC) of the device and a device custom name.

As an example, fig. 21 shows an operation interface provided by a certain application program, and as shown in fig. 21, a device list is presented in the operation interface.

As another example, fig. 22 shows another operation interface provided by some application program, as shown in fig. 22, a device list is presented in the operation interface, and the device list includes two sub-lists, a first sub-list includes a device identifier returned by the first bluetooth module, or a device identifier of a BLE class device, and a second sub-list includes a device identifier returned by the second bluetooth module, or a device identifier of an A2DP class device.

Step 203, receiving a pairing instruction input by a user according to the device list, where the pairing instruction includes a target device identifier.

When the user operates under the operation interface shown in fig. 21 or fig. 22 and selects the target device to be paired, a pairing instruction is generated, and the pairing instruction carries the target device identifier and the pairing key information. The application layer of the display device issues the pairing command to the functional module of the bottom layer, such as the precise pairing device provided by the application.

And 204, determining a target Bluetooth module according to the target equipment identifier, and sending the pairing instruction to the target Bluetooth module so as to pair the target Bluetooth module and the target equipment.

Specifically, it is first determined to which bluetooth module the target device identifier in the pairing instruction belongs to return device information, for example, it may be determined whether the target device identifier belongs to the first device information, and if so, the pairing instruction is sent to the first bluetooth module to indicate that the first bluetooth module is paired with the target device; if not, the pairing instruction is sent to the second Bluetooth module to indicate the second Bluetooth module to be paired with the target device.

Or, in another implementation, the device type corresponding to the target device identifier may also be searched for; if the corresponding device type is BLE, sending the pairing instruction to the first Bluetooth module; and if the corresponding device type is A2DP, sending the pairing instruction to the second Bluetooth module.

As can be seen from the foregoing embodiments, the present application provides a method for accurately pairing a dual hardware system display device and an external bluetooth device, and receives first device information and/or second device information; then, generating an equipment list according to the equipment identification in the first equipment information and/or the second equipment information; then receiving a pairing instruction input by a user according to the equipment list, wherein the pairing instruction comprises a target equipment identifier; and finally, determining a target Bluetooth module according to the target equipment identifier, and sending the pairing instruction to the target Bluetooth module so as to pair the target Bluetooth module and the target equipment.

In the method, in the scanning stage, the first device information is returned when the first bluetooth module determines that the device type in the first device information is BLE, the second device information is returned when the second bluetooth module determines that the device type in the second device information is A2DP, that is, the device information returned by each bluetooth module is the device information filtered by the corresponding bluetooth module according to the device type, so that the first bluetooth module and the second bluetooth module respectively return the device information corresponding to different types of bluetooth peripherals and no repetition exists. In the pairing stage, the first Bluetooth module and the second Bluetooth module respectively return the device information corresponding to the Bluetooth peripherals of different types without repetition, so that the user does not have trouble when selecting the target device to be paired, and the target Bluetooth module can be accurately judged according to the target device identification in the pairing instruction, thereby avoiding the situation that the target device is connected to the wrong Bluetooth module.

In some other embodiments, after the target bluetooth module is successfully paired with the target device, pairing response information is returned to the precise pairing apparatus, where the pairing response information includes a target device identifier. Based on this, the method of the present application may further include:

step 205, receiving pairing response information returned by the target bluetooth module, where the pairing response information includes a target device identifier.

Step 206, adding a mark to the target device identifier in the device list to indicate that the target device is paired.

As an example, fig. 23 shows an operation interface provided by an application program, and as shown in fig. 23, in the device list presented by the operation interface, the target device identifier includes a "paired" flag.
