[0041] Embodiment 1

[0042] Figure 1 A flowchart of a Bluetooth pairing method is provided for the first embodiment of the present invention. This embodiment is applicable to the case of Bluetooth pairing in the open source Hongmeng system. The method can be executed by a Bluetooth pairing device, which can be implemented in the form of hardware and / or software. Typically, the Bluetooth pairing device can be configured in an electronic device, such as a computer or a mobile terminal device. Figure 1 As shown, the method includes:

[0043] S110 . During the Bluetooth pairing process, if an input / output capability query request sent by the Bluetooth module is received, the input / output capability status is obtained.

[0044] In this embodiment, the input output (IO) capability reply instruction HCI IO Capability Request Reply of the Bluetooth host controller interface (HCI) can be optimized to avoid rejection of the Bluetooth module caused by repeated replies, thereby reducing the unresponsiveness of the Bluetooth module. HCI IO Capability Request Reply is a command in the Bluetooth protocol used to respond to the host's query of the Bluetooth controller's IO Capability.

[0045] For example, the HCI command interaction between the host and the controller during the Bluetooth pairing process in the prior art can be as follows: Figure 2 As shown. Among them, the host can be a device or software entity that runs Bluetooth applications and high-level protocols of the Bluetooth protocol stack, and the controller is a hardware or software component at a lower level in the Bluetooth protocol stack, usually referring to the firmware and hardware circuits in the Bluetooth chip or Bluetooth module, which are responsible for processing the underlying communication and physical layer operations of Bluetooth. Typically, the controller can correspond to the Bluetooth module in this embodiment. HCI defines the format and transmission method of commands, data and events between the host and the controller, so that the host can configure and control the controller, and the controller can report the underlying status and events to the host.

[0046] Specifically, first, the host sends an HCI Connection Request instruction to the controller, requesting to establish a Bluetooth connection with the specified device, and the controller replies with an HCI Connection Request Reply instruction to inform the HCI driver of the result of the connection request. Then the host sends an HCI Read Remote Version Information instruction to the controller to read the version information of the remote device and specify the connection handle; the controller sends an HCI ReadRemote Version Information Reply reply, which contains the version information of the remote device. The controller sends an HCI Max Slots Change reply, which contains the maximum number of time slots (slots) for data transmission. Then the controller sends an HCI Remote Name Request Complete to notify the host that the remote device name request has been completed and returns the device name of the remote device.

[0047] Then, the host sends HCI Read Remote Supported Features to query the Bluetooth features supported by the remote device, and the controller sends HCI Read Remote Supported Features Reply to reply with the Bluetooth feature information supported by the remote device. These features describe the functions and operations that the remote device can perform in Bluetooth communication. The host sends HCI Read Remote Extended Features to obtain the extended features of the remote device, and the controller sends HCI Read Remote Extended Features Reply in response. The host sends L2CAP informationRequest to request L2CAP (Logical Link Control and Adaptation Protocol) related information, and the controller sends L2CAPInformation Reply to reply with the corresponding L2CAP information. The controller sends HCI Number Of CompletedPackets to notify HCI of the number of completed data packets. The controller sends HCI IO Capability Response to provide information about the device's IO capabilities, which provides a basis for the subsequent pairing method selection. The controller sends HCI IOCapability Request to query the IO capabilities of the Bluetooth device; the host sends HCI IO Capability RequestReply to reply with the device's IO capability information. Due to the existence of historical HCI IO Capability Request corresponding events, the host will repeatedly send HCI IO Capability Request Reply commands to the controller, causing the Bluetooth module to become unresponsive.

[0048] In view of the problems existing in the prior art, in this embodiment, after receiving the input and output capability query request HCI IO Capability Request sent by the Bluetooth module controller, the current input and output capability status can be obtained. The input and output capability status can include a valid state and an invalid state.

[0049] S120: When it is detected that the input / output capability state is in an invalid state, the input / output capability state is updated to a valid state, and the input / output capability information is acquired.

[0050] Specifically, when it is determined that the input / output capability state is in an invalid state, the input / output capability state is updated to a valid state, and the current input / output capability information is searched and obtained. The input / output capability information includes at least one of supporting display only, supporting display yes / no, supporting keyboard input only, no input and no output, and supporting keyboard and display at the same time. The input / output capability information is used to describe the characteristics and functions of the Bluetooth device in terms of input and output, and can be pre-configured according to the model and performance parameters of the Bluetooth module.

[0051] S130: Generate an input / output capability query reply according to the input / output capability information, send the input / output capability query reply to the Bluetooth module, and update the input / output capability status to an invalid status.

[0052] Specifically, when ensuring that the input and output capability status is valid, the input and output capability query reply, i.e., the HCI IO Capability Request Reply instruction, is used to send the input and output capability information to the Bluetooth module, and after the sending is completed, the input and output capability status is immediately updated to an invalid state to ensure that the HCI IO Capability Request Reply instruction is only replied once. The HCI instruction interaction between the host and the controller after adopting the technical solution of this embodiment can be as follows: Figure 3 shown.

[0053] The technical solution of the embodiment of the present invention is as follows: during the Bluetooth pairing process, if an input / output capability query request is received from a Bluetooth module, the input / output capability status is obtained; when it is detected that the input / output capability status is invalid, the input / output capability status is updated to a valid status, and the input / output capability information is obtained; based on the input / output capability information, an input / output capability query reply is generated, the input / output capability query reply is sent to the Bluetooth module, and the input / output capability status is updated to an invalid status; by setting the input / output capability status to limit repeated responses to the input / output capability information, the stability of the Bluetooth pairing can be improved, and the Bluetooth compatibility can be improved.

[0054] Optionally, the technical solution of this embodiment may further include:

[0055] Obtaining a performance evaluation result corresponding to the Bluetooth module, and obtaining a query scan type corresponding to the Bluetooth module according to the performance evaluation result;

[0056] Through the Bluetooth module, paired device scanning is performed based on the inquiry scan type.

[0057] It should be noted that different types of Bluetooth modules usually have different performances. In this embodiment, performance evaluation can be performed on different types of Bluetooth modules in advance to obtain corresponding performance evaluation results. For example, the performance evaluation results may include excellent, good and poor, and the performance evaluation can be performed from multiple performance indicators such as transmission distance, transmission rate, stability, power consumption, etc. Secondly, for different performance evaluation results, the corresponding query scan type can be pre-set, and the corresponding relationship between the performance evaluation result and the query scan type can be generated and stored. Thus, after obtaining the performance evaluation result corresponding to the current Bluetooth module, the scan query type corresponding to the Bluetooth module can be obtained according to the pre-stored corresponding relationship. Finally, the query scan type can be sent to the Bluetooth module so that it performs a paired device scan based on the query scan type.

[0058] Among them, the inquiry scan type may include standard scan and / or interlaced scan. Inquiry scan is a mechanism used by Bluetooth devices to discover other Bluetooth devices around. In this embodiment, standard scan (0x00 Mandatory: Standard Scan) or interlaced scan (0x01 Optional: Interlaced Scan) can be set according to the characteristics of the module. Typically, standard scan scans each channel in sequence, which is suitable for Bluetooth modules with better performance, while interlaced scan may skip certain channels to speed up the scanning speed, which is more suitable for Bluetooth modules with poor performance. Therefore, for Bluetooth modules with good and poor performance evaluation results, the corresponding inquiry scan type can be set to interlaced scan, and for Bluetooth modules with excellent performance evaluation results, the corresponding inquiry scan type can be set to standard scan.

[0059] The advantage of the above settings is that it reduces the power consumption and bandwidth usage of the device, while ensuring a certain discovery speed, improving the stability of scanning, and reducing the occurrence of module unresponsiveness problems. It is applicable to Bluetooth 4.0 or Bluetooth 2.1.

[0060] Optionally, performing paired device scanning based on the query scan type by the Bluetooth module may include:

[0061] According to the inquiry scan type, an inquiry scan type setting instruction is generated, and the inquiry scan type setting instruction is sent to the Bluetooth module to perform paired device scanning through the Bluetooth module.

[0062] In this embodiment, the inquiry scan type of the Bluetooth module can be set through the inquiry scan type setting instruction HCI_Write_Inquiry_Scan_Type. Through this instruction, the host can control the behavior and characteristics of the Bluetooth device during the inquiry scan process.

[0063] In a specific example, the process of the query scan type setting method can be as follows: Figure 4 As shown. Specifically, according to the performance evaluation results of the Bluetooth module, the interleaved scan feature is set. If it is determined that the inquiry scan type is a standard scan, the interleaved scan feature is set to false, that is, the standard scan can be used. The host sends the HCI instruction HCIWrite Inquiry Scan Type (Type = Standard) to the Bluetooth module to set the inquiry scan (Inquiry Scan) type to the standard scan. If the inquiry scan type is an interleaved scan, the interleaved scan feature is set to true, and then the discoverMode can be set to GAP_INQUIRY_SCAN_TYPE_INTERLACED, and the connectableMode can be set to GAP_PAGE_SCAN_TYPE_INTERLACED. Next, the host will send the HCI instruction HCIWrite Inquiry Scan Type (Type = Interlaced) to the Bluetooth module to set the inquiry scan type to an interleaved scan.

[0064] Optionally, after performing paired device scanning based on the query scan type through the Bluetooth module, the following method may also be included:

[0065] If the current device is successfully queried and scanned, it is determined whether the current device has been successfully paired. If so, the device name corresponding to the current device is obtained through the Bluetooth module.

[0066] It should be noted that in the existing open source Hongmeng operating system, after the query scan is completed, the host begins to traverse and send HCI instructions HCI_Remote_Name_Request one by one to obtain the device name of the remote device. Among them, HCI_Remote_Name_Request is an important command in HCI, which is used to obtain the name of the remote device between Bluetooth devices. Its purpose is to be able to quickly and efficiently obtain device name information for device identification, management and other operations. The above operation will not cause the Bluetooth module with better fault tolerance to get stuck, the module just ignores it, but for the Bluetooth module with poor fault tolerance, receiving the instruction to obtain the device name before pairing will cause the paging of the Bluetooth module to time out or no response.

[0067] In view of the above problems, in this embodiment, the logic of HCI_Remote_Name_Request is optimized, and the original process of sending HCI_Remote_Name_Request instructions to each device after the query is completed is changed to only obtaining the device name of the paired device. In a specific example, the process of the device name acquisition method can be as follows: Figure 5 As shown. After successfully querying and scanning the current device, the device name of the current device is not directly obtained, but first determines whether the current device has been successfully paired. If it has been successfully paired and the device name of the current device has not been obtained, then the device name corresponding to the current device is obtained, that is, the HCI_Remote_Name_Request instruction is sent to the Bluetooth module to request the device name of the current device, so as to obtain the device name corresponding to the current device through the Bluetooth module; if it is determined that the current device has not been paired successfully, its device name is not obtained for the time being.

[0068] The advantage of the above settings is that for Bluetooth modules with poor fault tolerance, it can not only reduce the probability of paging timeout or no response in normal Bluetooth services and improve stability, but also reduce air interface occupancy and improve Bluetooth chip processing efficiency.

[0069] In this embodiment, by setting standard scanning or interleaved scanning according to the characteristics of the module, it is compatible with Bluetooth modules of different performances, improves Bluetooth compatibility and scanning stability, reduces the occurrence of module unresponsiveness, and is suitable for Bluetooth 4.0 or Bluetooth 2.1; secondly, by optimizing the logic of HCI IO Capability Request Reply, multiple replies are avoided to disrupt the processing of normal Bluetooth HCI instructions, reduce the unresponsiveness of Bluetooth modules, and improve Bluetooth compatibility; finally, by optimizing the logic of HCI_Remote_Name_Request, the probability of paging timeout or unresponsiveness in normal Bluetooth services can be reduced, stability can be improved, air interface occupancy can be reduced, and Bluetooth chip processing efficiency can be improved. The technical solution of this embodiment does not require special support from Bluetooth hardware, and only requires optimization in system services. It has universal applicability, lower implementation cost, and improves Bluetooth discovery, pairing, connection and other capabilities.
