Description

Technical Field

[0001] This application relates to the field of Bluetooth communication technology, and particularly to a Bluetooth connection method and related devices. Background Art

[0002] Currently, the interconnection between mobile devices and Bluetooth devices is mainly achieved through corresponding Bluetooth audio protocols or screen mirroring protocols. When the dual-end devices are interconnected based on the Bluetooth protocol, they have a high dependence on the dual-end system services. Under this limitation, when the dual-end system realizes the transfer of playback content at the client level, it highly depends on the two devices being connected to the same network environment.

[0003] Taking the Bluetooth interconnection between a mobile phone and a vehicle system as an example, the interconnection between the mobile phone and the vehicle system is mainly achieved through Bluetooth audio protocols (such as A2DP) or vehicle screen mirroring protocols (such as CarPlay, Android Auto, Hi Car) that are supported by both ends simultaneously. The client running on the mobile terminal needs to integrate the corresponding SDK to enable the mobile terminal, the client, and the vehicle system to support the corresponding Bluetooth protocol, and the two ends need to actively pair during the first connection.

[0051] The present application can be applied in the field of wireless communication technology. Specifically, it can be applied to the communication scenario of dual-terminal devices based on Bluetooth to achieve application-level Bluetooth connection. Figure 1 The following is a schematic structural diagram of a Bluetooth connection system provided by an embodiment of the present application, as Figure 1 shown, the system includes a first terminal device and a second terminal device. A public Bluetooth module providing public Bluetooth communication services is configured in both the first terminal device and the second terminal device, namely a first public Bluetooth module and a second public Bluetooth module respectively. The first public Bluetooth module and the second public Bluetooth module communicate with each other through a preset public Bluetooth protocol. For details, reference can be made to the prior art.

[0052] In this embodiment, the first terminal device and the second terminal device may each include, but are not limited to, mobile terminals such as mobile phones, laptop computers, PDAs (Personal Digital Assistants), PADs (Tablet Computers), etc., or fixed terminals such as desktop computers, multimedia large screens, in-vehicle devices, etc.

[0053] As Figure 1 shown, a first application runs on the first terminal device, and a second application runs on the second terminal device. The first application provides target multimedia data as a client application, and the second application realizes the transfer and playback of multimedia data as a server application. The embodiments of the present application provide a Bluetooth connection method, aiming to achieve Bluetooth connection between the first application and the second application based on the private Bluetooth protocol between the first application and the second application.

[0054] See Figure 2 , Figure 2 which is a schematic flowchart of a Bluetooth connection method provided by an embodiment of the present application. This method is applied to a Bluetooth connection system as shown in Figure 1 and, as shown in Figure 2 , this method includes:

[0055] S201. The first application sends a play transfer request to the first private Bluetooth server of the second application through the first private Bluetooth client.

[0056] In this embodiment, the play transfer request includes the unique identifier of the first terminal device, for example, the MAC address. The second application is the second application running on the second terminal device.

[0057] S202. The second application receives the play transfer request through the first private Bluetooth server and starts the second private Bluetooth server.

[0058] S203. The second application sends transfer confirmation information to the first private Bluetooth client through the first private Bluetooth server and listens to the first application through the second private Bluetooth server.

[0059] In this embodiment, the transfer confirmation information includes the unique identifier of the second terminal device, that is, the MAC address and the Universally Unique Identifier (UUID) of the second private Bluetooth server. Optionally, the transfer confirmation information further includes the device type.

[0060] S204. After the first application receives the transfer confirmation information sent by the second terminal device through the first private Bluetooth client, it creates a second private Bluetooth client according to the UUID of the second private Bluetooth server.

[0061] S205. The first application sends a second private Bluetooth connection request to the second private Bluetooth server through the second private Bluetooth client.

[0062] S206. The second application receives the second private Bluetooth connection request through the second private Bluetooth server. If it determines that a secure connection has not been established, it sends a secure connection request to the first application through the second public Bluetooth module.

[0063] S207. The first application receives the secure connection request through the first public Bluetooth module and obtains the connection instruction. If the connection instruction is an accept connection instruction, it establishes a secure connection with the second terminal device and sends the transfer play information of the target multimedia to the second private Bluetooth server through the second private Bluetooth client, so that the second application plays the target multimedia based on the transfer play information.

[0064] As can be seen from the above technical solution, in the Bluetooth connection method provided by the embodiment of the present application, the second private Bluetooth client and the second private Bluetooth server communicate through the second private Bluetooth protocol to achieve cross-network multimedia data transfer between devices. It is not necessary for the first terminal device and the second terminal device to be connected to the same local area network. The media resource information and playback status of the target multimedia are transmitted through the second private Bluetooth protocol between the second private Bluetooth client and the second private Bluetooth server, so as to achieve cross-network and cross-device content continuous playback, reduce repeated operations, and thus achieve seamless cross-network content transfer.

[0065] Further, Figure 3 The following is the specific implementation process of the Bluetooth connection method provided by the embodiment of the present application. As Figure 3 shown, this method specifically includes:

[0066] S301. After the first application is started and the home page content is loaded, obtain the discovered device list, paired device list, and historical connection device list.

[0067] In this embodiment, the discovered device list D1 includes at least one real-time online device. The real-time online device refers to the terminal device discovered by the first public Bluetooth module of the first terminal device. It can be understood that the real-time online device has enabled the public Bluetooth service and is configured to be discoverable.

[0068] In this embodiment, the paired device list D2 includes at least one paired device. The paired device refers to the terminal device in a Bluetooth paired state with the first terminal device.

[0069] It should be noted that the first application scans through the Bluetooth communication service of the first public Bluetooth module to obtain at least one real-time online device to generate the discovered device list, and obtains the paired device list from the historical pairing device information. The first public Bluetooth module is used to provide the Bluetooth communication service and maintain the discovered device list and the paired device list.

[0070] In this embodiment, the historical connection device list D3 includes at least one historical connection device. The historical connection device refers to the terminal device that has achieved Bluetooth connection through the first private Bluetooth server of the second application and the first private Bluetooth client of the first application before the current moment. It should be noted that the historical connection device list is saved and maintained by the first application.

[0071] S302. The first application traverses the discovered device list, detects whether the device type of each real-time online device is the target type, and adds the real-time online device of the target type as the target online device to the online device list.

[0072] In this embodiment, the target type is one or more of the preset types of terminal devices that can configure the second application. The target type is usually preset based on the application scenario. For example, in the scenario of automatic identification of in-vehicle Bluetooth, the target type is an in-vehicle device; in the scenario of automatic identification of a large screen, the target type is a large-screen Bluetooth device.

[0073] In this embodiment, there are various methods for detecting whether a real-time online device is of the target type according to the target type.

[0074] A1. When the target type is an in-vehicle device, the method for determining whether a real-time online device is an in-vehicle device includes:

[0075] Obtain the cached historical list of in-vehicle devices, and determine whether the real-time online device is an in-vehicle device through the Bluetooth device classification information and the MAC address of the real-time online device.

[0076] Or, determine whether the real-time online device is an in-vehicle device through the historical list of in-vehicle devices. The historical list of in-vehicle devices includes the MAC addresses of the historically connected in-vehicle devices. If the MAC address of the real-time online device is in the historical list of in-vehicle devices, it is determined that the real-time online device is an in-vehicle device.

[0077] A2. When the target type is a large-screen device, the method for determining whether a real-time online device is a large-screen device includes:

[0078] Obtain the cached historical list of large-screen devices, and determine whether the real-time online device is a large-screen device through the Bluetooth device classification information and the MAC address of the real-time online device.

[0079] Or, determine whether the real-time online device is a large-screen device through the historical list of large-screen devices. The historical list of large-screen devices includes the MAC addresses of the historically connected large-screen devices. If the MAC address of the real-time online device is in the historical list of large-screen devices, it is determined that the real-time online device is a large-screen device.

[0080] S303. The first application obtains the list of devices to be detected, traverses the list of devices to be detected, detects the connection status of each device to be detected with the first terminal device, and adds the device to be detected that is in a connected state with the first terminal device as a target online device to the online device list.

[0081] In this embodiment, the first application merges the paired device list and the historical connection device list to obtain an intermediate list, de-duplicates the intermediate list and filters out the real-time online devices to obtain the list of devices to be detected. The list of devices to be detected includes at least one device to be detected. It can be understood that the device to be detected is a terminal device that belongs to the paired device list and / or the historical connection device list and does not belong to the discovered device list.

[0082] In this embodiment, if the first terminal device is an Android device, the connection status between the device to be detected and the first terminal device can be obtained through the reflection of BluetoothDevice.isConnected.

[0083] S304. For each device to be detected that is in a non-connected state with the first terminal device, the first application sends a first private Bluetooth connection request to the device to be detected. If the device to be detected successfully responds to the first private Bluetooth connection request and establishes a first private Bluetooth connection with the first terminal device, the device to be detected is used as a candidate online device.

[0084] In this embodiment, for each device to be detected that is in a non-connected state with the first terminal device, the first application sends a first private Bluetooth connection request to the device to be detected, so that the second application of the device to be detected responds to the first private Bluetooth connection request through the first private Bluetooth server.

[0085] S305. For each device to be detected that is in a non-connected state with the first terminal device and fails to respond to the connection request of the first private Bluetooth server, the first application sends a GATT connection request to the device to be detected through the first public Bluetooth module. If the device to be detected responds to the GATT connection request and establishes a GATT connection with the first terminal device, the device to be detected is used as a candidate online device.

[0086] In this embodiment, the GATT connection request is a public Bluetooth connection request.

[0087] S306. For each candidate online device, the first application determines whether the device type of the candidate online device is the target type. If so, the candidate online device is added to the online device list as the target online device.

[0088] S307. The first application pushes the Bluetooth connection prompt information and the online device list, and disconnects the Bluetooth connection with all target online devices.

[0089] In this embodiment, the first application sends the Bluetooth connection prompt information and displays the online device list to prompt the user of the first application to select a target online device to enter the play transfer service.

[0090] In this embodiment, the list information of the online device list includes the device MAC (Media Access Control) address, device name, device classification parameter CoD, and universal unique identifier UUID of each target online device. It can be seen from the above technical solution that a Bluetooth connection method provided by an embodiment of the present application enables a first private Bluetooth client and a first private Bluetooth server to communicate through a first private RFCOMM protocol, and realizes the perception of the interconnection environment by probing online based on the discovered device list, paired device list, and historical connection device list. Specifically, by judging the connection status and target type of each terminal device in the three types of device lists obtained, the devices available for connection at present, that is, the target online devices, are identified.

[0091] Referring to Figure 4 Figure 4 FIG. is a schematic flowchart of another Bluetooth connection method provided by an embodiment of the present application. As Figure 4 shown, this method specifically includes:

[0092] S401. The first application receives a play transfer instruction.

[0093] In this embodiment, the play transfer instruction includes the device MAC address and device name of the second terminal device, and is used to indicate that the target multimedia is played through the second terminal device, where the second terminal device is a target online device selected by the user, and the target multimedia is the multimedia played in real time by the first application. Optionally, the type of the target multimedia is audio or video.

[0094] S402. The first application establishes a first private Bluetooth client according to the device MAC address of the second terminal device.

[0095] S403. The first application sends a first private Bluetooth connection request to the second terminal device through the first private Bluetooth client until the first private Bluetooth client is successfully connected to the second terminal device.

[0096] S404. After the second application of the second terminal device is started, a first private Bluetooth server is started, and the first private Bluetooth connection request is listened to through the first private Bluetooth server.

[0097] S405. The second application receives the first private Bluetooth connection request through the first private Bluetooth server and establishes a connection with the first private Bluetooth client.

[0098] S406. After the first private Bluetooth client is successfully connected to the first private Bluetooth server, the first application sends a play transfer request to the first private Bluetooth server of the second application through the first private Bluetooth client.

[0099] In this embodiment, after the first private Bluetooth client successfully connects to the first private Bluetooth server, data can be sent bidirectionally between the first private Bluetooth client and the first private Bluetooth server based on the first private Bluetooth protocol.

[0100] In this embodiment, the play transfer request carries a timestamp, the device name of the first terminal device, the MAC address of the first terminal device, and the device type of the first terminal device.

[0101] S407. The second application receives the play transfer request through the first private Bluetooth server and starts the second private Bluetooth server.

[0102] S408. The second application sends transfer confirmation information to the first private Bluetooth client through the first private Bluetooth server and listens to the first application through the second private Bluetooth server.

[0103] In this embodiment, the transfer confirmation information includes a timestamp, the device name of the second terminal device, the MAC address of the second terminal device, the device type (such as the device type parameter CoD), and the UUID of the second private Bluetooth server.

[0104] S409. After the first application receives the transfer confirmation information sent by the second terminal device through the first private Bluetooth client, it creates a second private Bluetooth client according to the UUID of the second private Bluetooth server.

[0105] Optionally, after the first application receives the transfer confirmation information sent by the second terminal device through the first private Bluetooth client, it can also store the device name, MAC address, and device type of the second terminal device in the historical connection device list.

[0106] S410. The first application sends a second private Bluetooth connection request to the second private Bluetooth server through the second private Bluetooth client.

[0107] In this embodiment, the second private Bluetooth connection request includes the MAC address of the second terminal device.

[0108] S411. The second application receives the second private Bluetooth connection request through the second private Bluetooth server, determines whether a secure connection has been established between the first terminal device and the second terminal device. If a secure connection has not been established, execute S412; if a secure connection has been established, execute S416.

[0109] S412. If a secure connection has not been established, the second application sends a secure connection request to the first application through the second public Bluetooth module.

[0110] In this embodiment, the secure connection request includes the MAC address of the first terminal device and the Bluetooth pairing code.

[0111] S413. The first application receives a secure connection request via the first common Bluetooth module and obtains a connection instruction.

[0112] In this embodiment, the first application receives and displays a secure connection request via the first common Bluetooth module, receives or automatically generates a connection instruction based on a Bluetooth pairing code. The connection instruction includes an accept connection instruction and a reject connection instruction.

[0113] S414. In response to the reject connection instruction, the first application issues a reject pairing indication and displays a re-pairing indication message.

[0114] That is, if the connection instruction is a reject connection instruction, the establishment of a secure connection between the first terminal device and the second terminal device fails.

[0115] In this embodiment, the re-pairing includes a pairing failure instruction and re-pairing information. The re-pairing information includes a list of online devices.

[0116] It should be noted that the specific method for the first application to issue a re-pairing indication message can refer to the above Figure 3 illustrated embodiment.

[0117] S415. After receiving the reject pairing indication, the second application closes the second private Bluetooth server.

[0118] In this embodiment, when the second application receives the reject pairing indication, indicating that the establishment of a secure connection between the first terminal device and the second terminal device fails, the second private Bluetooth server is closed.

[0119] S416. In response to the accept connection instruction, the first application establishes a secure connection with the second terminal device and sends streaming playback information to the second private Bluetooth server via the second private Bluetooth client.

[0120] In this embodiment, if the connection instruction is an accept connection instruction, the first application establishes a secure connection with the second terminal device via the first common Bluetooth module.

[0121] In this embodiment, the streaming playback information includes media asset information, playback status, and user login token information of the target multimedia.

[0122] S417. After receiving the streaming playback information via the second private Bluetooth server, the second application plays the target multimedia based on the media asset information and the playback status.

[0123] In this embodiment, the second private Bluetooth server and the second private Bluetooth client communicate via the second private Bluetooth protocol.

[0124] As can be seen from the above technical solutions, in a Bluetooth connection method provided by an embodiment of the present application, a second private Bluetooth client and a second private Bluetooth server communicate through a second private RFCOMM protocol to achieve cross-network multimedia data transfer between devices. It is not necessary for the first terminal device and the second terminal device to be connected to the same local area network. The media resource information and the playback status are transmitted through the second private Bluetooth protocol between the second private Bluetooth client and the second private Bluetooth server, so as to achieve cross-network and cross-device content continuation playback, reduce repeated operations, and thus achieve seamless cross-network content transfer.

[0125] Further, taking the mobile device as a mobile phone and the Bluetooth device as a vehicle-mounted Bluetooth device as an example, Figure 5 The following is a schematic structural diagram of a Bluetooth connection system provided by an embodiment of the present application. This system includes a mobile phone and a vehicle-mounted Bluetooth device. Both the mobile phone and the vehicle-mounted Bluetooth device are configured with a public Bluetooth module that provides public Bluetooth communication services, namely a first public Bluetooth module and a second public Bluetooth module. The first public Bluetooth module is used to provide the public Bluetooth communication service of the mobile phone system, and the second public Bluetooth module is used to provide the public Bluetooth communication service of the vehicle-mounted system.

[0126] Based on Figure 5 the Bluetooth connection system shown above, when entering the vehicle-mounted and large-screen interconnection environment, after the first application of the mobile phone is started, the detection process is automatically triggered. Or, when the first application of the mobile phone is playing a video and it is detected that the user clicks the screen mirroring button, the detection process is actively triggered. The detection process is also referred to the above 301~307. Through the non-secure Bluetooth client (i.e., the first private Bluetooth client) in the mobile application and the non-secure Bluetooth server (i.e., the first private Bluetooth server) in the vehicle-mounted application, an online device list is generated based on the discovered device list, the paired device list, the historical connection device list, and the online probing results.

[0127] The first application of the mobile phone detects that the user clicks the Bluetooth device screen mirroring instruction, and the Bluetooth device screen mirroring instruction includes a playback transfer instruction, such as opening the vehicle-mounted application of the vehicle-mounted Bluetooth device to achieve playback transfer. After the vehicle-mounted application of the vehicle-mounted Bluetooth device is started and it is detected that the non-secure Bluetooth server receives the playback transfer request, the second private Bluetooth server is started.

[0128] After the vehicle-mounted application starts the second private Bluetooth server, through the secure Bluetooth client (i.e., the second private Bluetooth client) in the mobile application and the secure Bluetooth server (i.e., the second private Bluetooth server) in the vehicle-mounted application, referring to S405~S407, the video transfer playback is achieved.

[0129] It should be noted that after the second application in S407 receives the play transfer request through the first private Bluetooth server, the login status of the in-vehicle application can also be judged. If it is safe, the non-safe Bluetooth server (i.e., the first private Bluetooth server) can be directly used to receive the media information and play status of the target multimedia, so as to achieve safe continuous playback. If it is not safe, the second private Bluetooth server is started.

[0130] It should be noted that taking the scenario of the interconnection between the mobile phone system and the in-vehicle system as an example, in the traditional Bluetooth connection method, the interconnection between the mobile phone and the in-vehicle system is mainly achieved through the in-vehicle screen mirroring protocols supported by both ends (such as CarPlay, Android Auto, HiCar), that is, the mobile and in-vehicle systems need to support the corresponding protocols, and the client running on the mobile terminal needs to integrate the corresponding protocol SDK to achieve the interconnection of the two ends of the client and realize functions such as account and play transfer. And the first connection between the two ends requires an active pairing process. That is to say, the traditional Bluetooth connection method depends on system protocol support, the application needs to be customized and integrated with the corresponding protocol SDK, and the first pairing process is required.

[0131] It can be seen from the above technical solutions that a Bluetooth connection method provided by an embodiment of the present application realizes the perception of the interconnection environment through the non-safe private RFCOMM protocol (i.e., the first private Bluetooth protocol) and the online probing of the paired Bluetooth devices, and realizes the cross-network data transfer between devices through the safe RFCOMM protocol (i.e., the second private Bluetooth protocol). Specifically, through the Bluetooth device classification information and the private protocol based on the non-safe Bluetooth RFCOMM connection, the in-vehicle or large-screen environment can be determined without user intervention and prior Bluetooth device binding, so as to realize the Bluetooth environment perception. Further, without the first terminal device and the second terminal device being connected to the same local area network, the account and play status are transmitted through the private service, so as to realize the cross-network and cross-device content continuous playback, reduce repeated operations, and thus realize the seamless cross-network content transfer.

[0132] In summary, a Bluetooth connection method provided by an embodiment of the present application can overcome the technical disadvantages of the traditional Bluetooth connection method that depends on system protocol support, the application needs to be customized and integrated with the corresponding protocol SDK (Software Development Kit), and the first pairing process is required.
