Description

Technical Field

[0001] This application relates to the field of near-field communication technology, such as a method, apparatus, and system for debugging NFC parameters. Background Technology

[0002] With the widespread adoption of NFC (Near Field Communication) technology in wearable smart devices, using NFC to function as public transport cards, access cards, bank cards, car keys, and more has become an essential function for users in their daily lives. However, as NFC is widely used in real-world scenarios, compatibility issues inevitably arise (i.e., compatibility problems between NFC devices and external card readers or cards). Solving these problems requires dynamically adjusting relevant NFC parameters based on the actual external environment.

[0003] Currently, smart wearable devices lack a universal and convenient method for updating NFC parameters. Field debugging personnel cannot dynamically adjust parameters according to actual scenarios and quickly verify their effects. Parameter modifications rely on software developers modifying code and compiling new versions, which greatly affects the efficiency of field debugging.

[0028] Figure 1 This is a schematic diagram of an environment for debugging NFC parameters provided in an embodiment of this disclosure. Figure 1 As shown, this disclosure provides a system 1 for debugging NFC parameters, including a wearable device 10 and a remote device 20.

[0029] Figure 2 This is a schematic diagram of an environment for another system for debugging NFC parameters provided in an embodiment of this disclosure. For example... Figure 2As shown, the remote device 20 includes a terminal device 201 or a card reader 202. The terminal device 201 includes an NFC parameter debugging application 2011. The card reader 202 is electrically connected to a host computer 203 that has an NFC parameter debugging tool 2031 installed. The NFC parameter debugging tool 2031 is used to connect to the card reader 202, establish an NFC connection with the wearable device 10 through the card reader 202, and complete data interaction through the card reader 202. Here, the connection between the card reader 202 and the host computer 203 can be via a USB (Universal Serial Bus) electrical connection.

[0030] In some optional embodiments, when the remote device 20 is a terminal device 201, the NFC parameter debugging command is issued by the NFC parameter debugging application 2011. In other optional embodiments, when the remote device 20 is a card reader 202, the NFC parameter debugging command is issued by the NFC parameter debugging tool 2031 installed on the host computer 203. The NFC parameter debugging command includes an NFC parameter update command or an NFC parameter read command, and the NFC parameter update command includes updating NFC parameters.

[0031] Optionally, the wearable device 10 includes a device host 101 and an NFC controller 102.

[0032] The device host 101 is connected to the NFC controller 102 via I2C (Inter-Integrated Circuit, serial communication bus). The device host 101 also interacts with remote devices via an RF front-end.

[0033] Optionally, the device host 101 includes an NFC SDK 1011 (Near Field Communication Software Development Kit). The NFC SDK 1011 is a collection of tools and interfaces for building applications that interact with the remote device 20. The NFC SDK 1011 is configured to support data interaction using the T4T NDEF (NFC Data Exchange Format) protocol specification to update NFC parameters, and to support data interaction via private commands to update NFC parameters. The NFC SDK 1011 is also configured to support reading / updating NFC parameters. The NFC SDK 1011 is further configured to receive and parse commands sent by the remote device 20. These commands include, but are not limited to, application selection commands and NFC parameter debugging commands.

[0034] Optionally, NFC SDK 1011 includes NCI (NFC Controller Interface). NFC SDK 1011 is also configured to assemble received contactless data into an NCI instruction format and send it to NFC controller 102 via I2C.

[0035] The NFC controller 102 acquires near-field communication data through the radio frequency front end, and is used for communication between the NCI and the device host 101, as well as for configuring the operating mode. The operating modes include card emulation mode, card reading mode, and peer-to-peer mode.

[0036] Based on the system configuration of the system used for debugging NFC parameters described above, combined with Figure 3 As shown, this disclosure provides a method for debugging NFC parameters, including: S01, in card emulation mode, the wearable device establishes an NFC connection with a remote device performing card reading mode.

[0037] In this step, the wearable device establishes an NFC connection with the remote device performing the card reading mode, including: the wearable device receiving a tag detection command sent by the remote device; and after receiving the tag detection command, sending card information to the remote device to establish an NFC connection with the remote device performing the card reading mode.

[0038] S02, the wearable device receives an application selection command sent by the remote device, generates a selection status code based on the application selection command, and sends it to the remote device so that the remote device can initiate NFC parameter debugging based on the selection status code. The selection status code indicates that the wearable device has successfully learned that the remote device has the capability for NFC parameter management.

[0039] S03, the wearable device receives the NFC parameter debugging command sent by the remote device and performs NFC parameter debugging based on the NFC parameter debugging command.

[0040] The method for debugging NFC parameters provided in this disclosure establishes an NFC connection between a wearable device and a remote device in card reading mode while the wearable device is in card emulation mode. After establishing the NFC connection, the wearable device receives an application selection command from the remote device, generates a selection status code based on the command, and sends it to the remote device to initiate NFC parameter debugging. After the remote device initiates NFC parameter debugging, the wearable device receives an NFC parameter debugging command from the remote device and performs NFC parameter debugging based on the command. This disclosure achieves NFC parameter management through near-field communication between the wearable device and the remote device, eliminating the need for software implementation during field debugging and improving the efficiency of field debugging.

[0041] Optionally, combined Figure 4 As shown, the wearable device receives an application selection command sent by a remote device, generates a selection status code based on the application selection command, and sends it to the remote device, including: S11, the wearable device receives the application selection instruction sent by the remote device through the NFC controller and forwards it to the device host.

[0042] S12, the wearable device obtains the parsing result by parsing the application selection command through the device host.

[0043] S13, if the parsing result indicates that the NFC parameter management application is selected, the wearable device generates a selection status code through the device host and sends it to the NFC controller.

[0044] S14, the wearable device sends a selection status code to the remote device in a contactless manner through the NFC controller, so that the remote device can start NFC parameter debugging based on the selection status code.

[0045] In this way, after the wearable device establishes an NFC connection with the remote device in card reader mode, it receives the application selection command sent by the remote device through the NFC controller and forwards it to the device host. The device host then parses the application selection command to obtain the parsing result. If the parsing result indicates that the NFC parameter management application is selected, it means that the remote device has a need to update or read NFC parameters. At this time, the wearable device generates a selection status code through the device host and sends it to the NFC controller. Finally, the wearable device sends the selection status code to the remote device in a contactless manner through the NFC controller to start the operation of NFC parameter management. In this embodiment, the wearable device can know whether the remote device has a need to update / read NFC parameters based on the application selection command, and notify the remote device of the need result by means of a selection status code, thereby starting NFC parameter management. In this way, NFC parameter management is realized through near-field communication between the wearable device and the remote device, eliminating the dependence of field debugging on software and improving the efficiency of field debugging.

[0046] Optionally, the wearable device receives an application selection instruction sent by a remote device, generates a selection status code based on the application selection instruction, and sends it to the remote device, further including: After the wearable device obtains the parsing result by parsing the application selection command through the device host, if the parsing result is not the NFC parameter management application to be selected, the device host generates an error status code and sends it to the NFC controller.

[0047] Wearable devices send error status codes to remote devices in a contactless manner via an NFC controller.

[0048] In this way, after the wearable device learns from the application selection command that the remote device does not have the need to update / read NFC parameters, it notifies the remote device with an error status code, thus balancing the efficiency and reliability of field debugging.

[0049] Optionally, the wearable device receives an NFC parameter debugging command sent by a remote device, and performs NFC parameter debugging based on the NFC parameter debugging command, including: When the NFC parameter debugging command is an NFC parameter update command, the wearable device updates the NFC parameters based on the NFC parameter update command through the device host and obtains the parameter update status code; or... When the NFC parameter debugging command is an NFC parameter read command, the wearable device reads the NFC parameters and obtains the parameter read status code through the device host based on the NFC parameter read command.

[0050] Thus, when the NFC parameter debugging command is an NFC parameter update command, the wearable device updates the NFC parameters and obtains the parameter update status code through the device host. Conversely, when the NFC parameter debugging command is an NFC parameter read command, the wearable device reads the NFC parameters and obtains the parameter read status code through the device host. Therefore, this embodiment of the present disclosure can perform corresponding NFC parameter management operations based on NFC parameter management requirements during field debugging, and obtain the corresponding NFC parameter management status, enabling timely reporting of field debugging results and further improving the efficiency of field debugging.

[0051] It should be noted that wearable devices update NFC parameters based on NFC parameter update commands via the NCI of the NFC SDK in the device host, or read NFC parameters based on NFC parameter read commands via the NCI of the NFC SDK in the device host.

[0052] Combination Figure 5 As shown in the embodiments of this disclosure, a method for debugging NFC parameters is also provided, including: S21, in card emulation mode, the wearable device establishes an NFC connection with a remote device performing card reading mode.

[0053] S22, the wearable device receives an application selection command sent by the remote device, generates a selection status code based on the application selection command, and sends it to the remote device so that the remote device can start NFC parameter debugging based on the selection status code. Then proceed to step S23 or step S25.

[0054] S23, when the NFC parameter debugging command is an NFC parameter update command, the wearable device updates the NFC parameters through the device host based on the NFC parameter update command and obtains a parameter update status code. The device host then forwards the parameter update status code to the NFC controller. The parameter update status code indicates the success of the wearable device updating the NFC parameters. For example, if the wearable device successfully updates the NFC parameters through the device host based on the NFC parameter update command, the parameter update status code is a success status code; if the wearable device fails to update the NFC parameters through the device host based on the NFC parameter update command, the parameter update status code is a failure status code.

[0055] S24, the wearable device sends a parameter update status code to a remote device in a contactless manner via the NFC controller.

[0056] S25, when the NFC parameter debugging command is an NFC parameter read command, the wearable device reads the NFC parameters and obtains the parameter read status code through the device host based on the NFC parameter read command, and then forwards the parameter read status code and the NFC parameters to the NFC controller through the device host. The parameter read status code indicates the success of the wearable device reading the NFC parameters. As an example, if the wearable device successfully reads the NFC parameters through the device host based on the NFC parameter read command, the parameter read status code is a success status code; if the wearable device fails to read the NFC parameters through the device host based on the NFC parameter read command, the parameter read status code is a failure status code.

[0057] S26, the wearable device obtains encapsulated data by encapsulating NFC parameters and parameter reading status codes through the NFC controller, and sends the encapsulated data to the remote device in a contactless manner.

[0058] Using the NFC parameter debugging method provided in this disclosure, a wearable device establishes an NFC connection with a remote device performing card reading mode in card emulation mode. After establishing the NFC connection, the wearable device receives an application selection command sent by the remote device, generates a selection status code based on the application selection command, and sends it to the remote device so that the remote device can initiate NFC parameter debugging based on the selection status code. When the NFC parameter debugging command is an NFC parameter update command, the wearable device updates the NFC parameters through the device host based on the NFC parameter update command and obtains a parameter update status code. The device host then forwards the parameter update status code to the NFC controller to send the parameter update status code to the remote device via a contactless method. When the NFC parameter debugging command is an NFC parameter read command, the wearable device reads the NFC parameters through the device host based on the NFC parameter read command and obtains a parameter read status code. The device host then forwards the parameter read status code and NFC parameters to the NFC controller to encapsulate the NFC parameters and parameter read status code before sending them to the remote device via a contactless method. Thus, the embodiments of this disclosure can perform corresponding NFC parameter management operations based on NFC parameter management requirements during field debugging, and synchronously feed back the read NFC parameters and parameter read status codes when the NFC parameter management requirement is an NFC parameter read command, or feed back parameter update status codes when the NFC parameter management requirement is an NFC parameter update command, thereby realizing timely reporting of field debugging results and further improving the efficiency of field debugging.

[0059] Optionally, after the wearable device updates the NFC parameters based on the NFC parameter update command through the device host and obtains the parameter update status code, it sends an RF restart command through the device host to realize the NFC parameter update.

[0060] This allows wearable devices to restart according to the updated NFC parameters, improving the real-time performance of field testing.

[0061] Combination Figure 6 As shown in the embodiments of this disclosure, a method for debugging NFC parameters is also provided, including: S31, in card reader mode, the remote device establishes an NFC connection with the wearable device that performs the card emulation mode.

[0062] S32, the remote device sends an application selection command to the wearable device.

[0063] S33, the remote device receives the selection status code sent by the wearable device and starts NFC parameter debugging based on the selection status code.

[0064] S34, the remote device sends an NFC parameter debugging command to the wearable device so that the wearable device can perform NFC parameter debugging based on the NFC parameter debugging command.

[0065] The method for debugging NFC parameters provided in this disclosure establishes an NFC connection between a remote device in card reader mode and a wearable device in card emulation mode. After establishing the NFC connection, the remote device sends an application selection command to the wearable device and receives a selection status code from the wearable device to initiate NFC parameter debugging based on the selection status code. After initiating NFC parameter debugging, an NFC parameter debugging command is sent to the wearable device to enable it to perform NFC parameter debugging based on the command. This disclosure achieves NFC parameter management through near-field communication between the remote device and the wearable device, eliminating the need for software implementation during field debugging and improving the efficiency of field debugging.

[0066] Optionally, the method for debugging NFC parameters also includes: After the remote device sends an NFC parameter debugging command to the wearable device, it obtains the parameter update status code or encapsulated data sent by the wearable device.

[0067] The remote device displays the parameter update result corresponding to the NFC parameter update command according to the update status code.

[0068] The remote device displays the parameter reading results corresponding to the NFC parameter reading command according to the encapsulated data.

[0069] In this way, field personnel can know the parameter update status under field debugging in real time based on the parameter update results, and know the parameter reading status under field debugging based on the parameter reading results, which not only ensures the efficiency of field debugging, but also improves the real-time performance of field debugging.

Optionally, the apparatus 70 may further include a communication interface 702 and a bus 703.
