Detailed Description

The technical solution of the present application will be clearly described below with reference to the accompanying drawings in the present application.

The terminology used in the following embodiments of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application. As used in the specification of the present application and the appended claims, the singular forms "a", "an", "the" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that although the terms first, second, etc. may be used in the following embodiments to describe a class of objects, the objects should not be limited to these terms. These terms are only used to distinguish between particular objects of that class of objects. For example, the following embodiments may employ the terms first, second, etc. to describe electronic devices, but the electronic devices referred to in this application should not be limited by these terms. These terms are only used to distinguish between different electronic devices.

The following describes an exemplary implementation scenario of the present application.

Fig. 1 illustrates a WiFi access system 10, where the WiFi access system 10 includes a first device 11, a second device 12, and a wireless Access Point (AP) device 13. Wherein the first device 11 is wirelessly connected with the AP device 13. The second device 12 is a device that needs to access the wireless network through the AP device 13.

The first device 11 and the second device 12 related to the present application may be any devices that support wireless network connection, including: smart phones, tablet computers, smart home devices, industrial control devices, vehicle devices, and the like. The smart home devices can be, for example, smart televisions, smart monitors, smart air conditioners, smart refrigerators, and the like. The industrial control device may be, for example, a supply chain monitoring device, a goods management device, or the like. The vehicular apparatus may be, for example, an in-vehicle apparatus, an automatic navigation apparatus, an intelligent parking apparatus, or the like.

In some embodiments, the first device 11 is, for example, an electronic device including a User Interface (UI), such as a mobile phone, a tablet, a wearable electronic device (e.g., a smart watch), a car recorder, and the like. The UI of the electronic device may be, for example, a touch-sensitive surface or touch panel, etc. In this embodiment, the first device 11 may be referred to as an access device (access device) or a proxy device (agent device), and is not limited herein. In some embodiments, the first device 11 may receive, through the UI, setting information input by a user, where the setting information is used to trigger the first device 11 to perform information interaction with the second device 12 and the AP device 13, so as to complete an operation of the second device 12 to access the wireless network. In some embodiments, the second device 12 is, for example, an electronic device that does not include a user interface UI, e.g., a smart home device, an industrial control device, a vehicle device, etc. In the embodiment of the present application, the second device 12 may be referred to as a to-be-configured network IoT device or a proxied device.

The "UI" referred to in this application is a media interface for interaction and information exchange between an application or operating system and a user, which enables conversion between an internal form of information and a form acceptable to the user. The user interface of the application program is a source code written by a specific computer language such as java, extensible markup language (XML), and the like, and the interface source code is analyzed and rendered on the terminal device, and finally presented as content that can be identified by the user, such as controls such as pictures, characters, buttons, and the like. Controls, also called widgets, are basic elements of user interfaces, and typically have a toolbar (toolbar), menu bar (menu bar), text box (text box), button (button), scroll bar (scrollbar), picture, and text. The properties and contents of the controls in the interface are defined by tags or nodes, such as XML defining the controls contained by the interface by nodes < Textview >, < ImgView >, < VideoView >, and the like. A node corresponds to a control or attribute in the interface, and the node is rendered as user-viewable content after parsing and rendering.

A commonly used presentation form of the user interface is a Graphical User Interface (GUI), which refers to a user interface related to operations and displayed in a graphical manner. It may be an interface element such as an icon, a window, a control, etc. displayed in the display screen of the electronic device, where the control may include a visual interface element such as an icon, a button, a menu, a tab, a text box, a dialog box, a status bar, a navigation bar, a Widget, etc.

The AP device 13 referred to in the present application may be used as a "wireless access node" in a wireless network. The AP device 13 is used to access wireless clients (e.g., the first device 11 and the second device 12) to the wireless network, on the one hand, and the AP device 13 is also used to transmit communication information of devices within signal coverage, on the other hand. The AP device 13 may include a router, switch, wireless network card, modem, and the like.

The common implementation process of the existing network distribution method includes that the first device 11 acquires WiFi configuration information of the AP device 13, and then sends the WiFi configuration information to the second device 12. As can be seen, the WiFi configuration information needs to be forwarded via a third-party device (i.e., the first device 11 described in this application), so that the WiFi configuration information has a risk of leakage and is poor in security. In addition, the first device 11 typically transmits WiFi configuration information by way of broadcast. In this way, not only the second device 12 can access the network according to the WiFi configuration information, but also other devices located within the coverage area of the AP device 13 can access the network according to the WiFi configuration information, so that the information of the devices in the network is at risk of leakage, and the security of the network is poor.

The application provides a WiFi network connection method and device, wherein a first device acquires a device identifier of a second device, and then sends the device identifier of the second device to an AP device. And then, the AP equipment directly establishes WiFi connection with the second equipment according to the equipment identification. Therefore, the first device does not need to forward the WiFi configuration information to the second device, the situation that other devices acquire the WiFi configuration information and access to a network can be avoided, and the safety can be improved.

It should be understood that the embodiments of the present application may also be applicable to other future-oriented communication technologies. The system architecture, the device and the service scenario described in this application are for more clearly illustrating the technical solution of this application, and do not constitute a limitation to the technical solution provided in this application, and it can be known by those skilled in the art that the technical solution provided in this application is also applicable to similar technical problems along with the evolution of the system architecture and the appearance of new service scenarios.

The demodulator is used for demodulating the received electromagnetic wave signal into a low-frequency baseband signal. The demodulator then passes the demodulated low frequency baseband signal to a baseband processor for processing. The low frequency baseband signal is processed by the baseband processor and then transferred to the application processor. In some embodiments, the modem processor may be a stand-alone device. In other embodiments, the modem processor may be independent of processor 110.

The pressure sensor 160A is used for sensing a pressure signal, and can convert the pressure signal into an electrical signal. In some embodiments, pressure sensor 160A may be disposed on display screen 150. The pressure sensor 160A can be of a wide variety, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 160A, the capacitance between the electrodes changes. The first device 100 determines the intensity of the pressure from the change in capacitance. When a touch operation is applied to the display screen 150, the first device 100 detects the intensity of the touch operation according to the pressure sensor 160A. The first device 100 may also calculate the position of the touch from the detection signal of the pressure sensor 160A.

Touch sensor 160B, which may also be referred to as a touch panel or touch sensitive surface. The touch sensor 160B may be disposed on the display screen 150, and the touch sensor 160B and the display screen 150 form a touch screen, which is also called a "touch screen". The touch sensor 160B is used to detect a touch operation applied thereto or therearound. The touch sensor can communicate the detected touch operation to the application processor to determine the touch event type. Visual output associated with the touch operation may be provided through the display screen 150. In other embodiments, the touch sensor 160B may be disposed on the surface of the first device 100, at a different position than the display screen 150. In some embodiments, the touch sensor 160B provides a function of the first device 100 to receive trigger information input by a user.

For example, if the first device 100 includes a camera, the first device 100 may capture a still image, such as a two-dimensional code, through the camera. The static image is projected to the photosensitive element through the optical image generated by the camera. The photosensitive element may be a Charge Coupled Device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The light sensing element converts the optical signal into an electrical signal, which is then passed to the ISP where it is converted into a digital image signal. And the ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into information contained in a two-dimensional code, for example, identification information of the second device 200.

The two-dimensional code (2-dimensional barcode), also called a two-dimensional barcode, is a black-and-white alternate pattern that is distributed in a two-dimensional direction (plane) according to a certain rule by using a certain specific geometric figure, and is used for storing information such as characters, numbers, pictures and the like. Illustratively, a two-dimensional code is a combination of several geometric figures, where each figure represents a character or data using a binary representation. Based on this, the first device 100 can identify binary data recorded in the length direction and the width direction of the two-dimensional code by scanning the two-dimensional code, and further analyze the obtained binary data to acquire information contained therein.

The following provides an exemplary description of the implementation process of the present application from the perspective of human-computer interaction.

The WiFi network connection method described in this application may include at least one embodiment, in some embodiments, for example, the first device 100 may obtain the identification information of the second device 200 through NFC (hereinafter, an implementation manner corresponding to this embodiment is referred to as "manner one"), and in other embodiments, for example, the first device 100 may obtain the identification information of the second device 200 through scanning a two-dimensional code (hereinafter, an implementation manner corresponding to this embodiment is referred to as "manner two"). Specific implementation is described in detail below and will not be described in detail here. Based on this, corresponding to different embodiments, the interaction process between the user and each device is different, and the effect presented by the device is also different. The man-machine interaction process corresponding to different embodiments is described below with reference to examples.

Illustratively, as shown in fig. 3A, in the present embodiment, the first device 100 is embodied as a smart phone 31, the second device 200 is embodied as a smart washing machine 32, and the AP device 300 is embodied as a router 33. The smart phone 31 and the smart washing machine 32 are both provided with an NFC module and a WiFi module. The smartphone 31 further includes a display screen and a camera, the display screen of the smartphone 31 may be implemented as the display screen 150 illustrated in fig. 2A, and the camera of the smartphone 31 may be implemented as the camera illustrated in fig. 2A. The router 33 has at least one of a function of actively initiating a WiFi connection and a function of triggering the intelligent washing machine 32 to initiate a WiFi connection. The smartphone 31 has established a WiFi connection with the router 33, for example, using its own WiFi module, and the smart washing machine 32 has not established a WiFi connection with the router 33.

Before performing the following operations, the user may install a router management APP on the smartphone 31.

Further, with reference to fig. 3A, when the first mode is adopted in the present application to implement WiFi network connection, the implementation process is as follows:

opening NFC function of smartphone 31 and smart washer 32

Before the user uses the intelligent washing machine 32, the power plug of the intelligent washing machine 32 can be connected with the power supply, so that the NFC module in the intelligent washing machine 32 is triggered to be started, and the WiFi module in the intelligent washing machine 32 is triggered to be started.

For example, the initial state of the NFC module in the smartphone 31 is an off state. Further, the user may manually turn on the NFC module in the smartphone 31.

In some embodiments, after smartphone 31 presents the home interface shown in fig. 3B-1, the user slides from the end where the "navigation bar" is located to the end of the "menu bar" to call up the "phone status bar". The "navigation bar" refers to an icon bar containing an operator identifier, a signal quality identifier, an electric quantity identifier, and the like in the main interface. The menu bar is an icon bar for setting Applications (APPs) such as telephone, short message and WeChat in the main interface.

It should be noted that, in the actual operation, the operation of the user invoking the "mobile phone status bar" is not limited by the trigger position. For example, the user can call up "cell phone status bar" by performing a slide operation at a position to the left of the interface illustrated in fig. 3B-1. Similarly, the user can call up the "cell phone status bar" by performing a sliding operation at the right position of the interface illustrated in fig. 3B-1. This is not limited by the present application.

After the user slides the "cell phone status bar" called out, the smartphone 31 presents, for example, the interface illustrated in fig. 3B-2. The user can see functional icons of "WLAN", "bluetooth", "flashlight", "flight mode", "auto-spin", "NFC", etc. in the "cell phone status bar", and the user can determine the status of the corresponding function according to the color or brightness presented by the icon. The icon is gray or dark, which can indicate that the function corresponding to the icon is in the off state, and the icon is bright, which can indicate that the function corresponding to the icon is in the on state. For example, the icon of "WLAN" illustrated in fig. 3B-2 appears bright, illustrating that the wireless networking function of the smartphone 31 is in an on state. As another example, "NFC" illustrated in fig. 3B-2 appears gray or dark, indicating that the NFC communication function of the smartphone 31 is in an off state.

Furthermore, the user can switch the state of the function corresponding to the icon by clicking the icon in the mobile phone status bar. As shown in fig. 3B-3, the user may click on the "NFC" icon in the "cell phone status bar" to turn on the NFC communication function of the smartphone 31. Accordingly, after the user clicks the "NFC" icon, the "NFC" icon appears bright (not shown in the figure), and the NFC communication function of the smartphone 31 is turned on. Similarly, when the user wants to close some functions, the user can also trigger by clicking the corresponding icon. For example, the "bluetooth" icon appears bright, for example, indicating that the bluetooth function of the smartphone 31 is in an on state. After clicking the Bluetooth icon, the user triggers the Bluetooth function to close. Accordingly, the "bluetooth" icon appears gray or dark.

The embodiment illustrated in fig. 3B-1 through 3B-3 is merely one exemplary operation by the user. In actual use, the user may also turn on the NFC function of the smartphone 31 through other operation modes. And will not be described in detail herein.

Forwarding identification information of smart washing machine 32 using smart phone 31

As shown in fig. 3C, after the NFC function of the smartphone 31 and the NFC function of the smart washing machine 32 are turned on, the user may hold the smartphone 31 close to the smart washing machine 32. Furthermore, the user can see a dialog box "acquire information" W0330 ", automatically close after 5 seconds", for example, on the interface of the smartphone 31. The dialog box contains a "close" button and the number of seconds in the dialog box is reduced by 1 every second, starting with 5. The user may trigger a "close" button to close the dialog box before it is automatically closed. In the present embodiment, "W0330" is, for example, identification information of the intelligent washing machine 32.

Further, as shown in fig. 3D, after the user holds the smartphone 31 close to the smart washing machine 32 for a while, the user can see the notification message of "device W0330 accessing the WiFi network" on the interface of the smartphone 31.

Among them, between the embodiment illustrated in fig. 3C to the embodiment illustrated in fig. 3D, the intelligent washing machine 32 and the router 33 perform information interaction to execute the WiFi network connection method of the present application. The implementation processes of the intelligent washing machine 32, the intelligent washing machine 32 and the router 33 are described in detail in the following embodiments, and will not be described in detail here.

It is understood that fig. 3B-1 through 3D are merely schematic depictions that do not limit the scope of the present application. In other embodiments, depending on the operating system of the smartphone 31, the interface presented by the smartphone 31 after receiving the trigger of the user may be other, and the information content in the notification dialog box may be other. Accordingly, the operation steps of the user opening the NFC function and the user opening the authority of the router 33 may be different from the descriptions of fig. 3B-1 to 3B-3. And so on. And will not be described in detail herein.

Therefore, by adopting the implementation mode, the user only needs to start the NFC of the first device and the second device, and then the first device is close to the second device, so that the purpose of establishing WiFi connection between the second device and the AP device can be achieved, the operation convenience of the user can be improved, and the use experience of the user is improved.

With reference to fig. 3A, when the WiFi network connection is implemented in the second mode, the implementation process is as follows:

generating two-dimensional code

As shown in fig. 4A, the intelligent washing machine 32 includes, for example, an "equipment information" button and a display screen. The user can press the "device info" button, after which the user can see the two-dimensional code on the display screen. The two-dimensional code contains identification information of the intelligent laundry machine 32.

In addition, in some embodiments, the second device 200 is, for example, a device that does not include a display screen, such as a smart sound box, and then the two-dimensional code including the identification information may be generated in advance at the time of factory shipment and marked on the housing of the second device 200.

In this embodiment, the user may control the smart phone 31 to scan the two-dimensional code of the smart washing machine 32, so that the smart phone 31 obtains the identification information of the smart washing machine 32, and then, the smart phone 31 is triggered to send the identification information of the smart washing machine 32 to the router 33, so as to establish WiFi connection between the smart washing machine 32 and the router 33. Illustratively, the user may use the router management APP to scan the two-dimensional code of the intelligent laundry machine 32.

Illustratively, as shown in FIG. 4B-1, the user clicks on the router management APP to enter the router management host interface.

As shown in fig. 4B-2, the user can see icon "…" in the upper right corner of the router administration home interface. Thereafter, the user clicks on icon "…" to bring up a menu of functions.

As shown in fig. 4B-3, the function menu includes function items such as "disconnect", "restart the router", "scan", and the like, and the user can trigger the "scan" function to enter the interface for scanning the two-dimensional code.

Further, as shown in fig. 4B-4, the interface center of the smartphone 31 includes a square scan frame, and the electron beam periodically moves from one frame of the scan frame to the opposite frame of the scan frame to scan the image in the scan frame. The user can aim at the two-dimensional code of the intelligent washing machine 32 with the camera of the intelligent mobile phone 31, so that the two-dimensional code of the intelligent washing machine 32 is completely positioned in the scanning frame until the intelligent mobile phone 31 sends out a prompt tone for completing scanning.

After that, the user may see, for example, a notification interface for acquiring the identification information, which is illustrated in fig. 3C, on the interface of the smartphone 31. Further, after a period of time, the user can see a notification interface on the interface of the smartphone 31 that the connection is successful, as illustrated in fig. 3D. And will not be described in detail herein.

It is to be understood that fig. 3A to 4B-4 are only schematic illustrations and do not limit the WiFi network connection method of the present application. In some other embodiments of the present application, the smartphone 31 may present other display effects in response to the operation of the user, and accordingly, the processes of setting by the user and the like may also be different from those described in the foregoing embodiments. In addition, during the information interaction between the smart phone 31 and the router 33, and during the information interaction between the router 33 and the smart washing machine 32, the smart phone 31 may also present other display effects, or may not present any display effect, and the like. And are not limited herein.

It should be noted that, in some existing implementation methods, in order to forward WiFi configuration information to a second device using a first device, a user needs to first operate the first device to disconnect a WiFi connection with an AP device, and then operate the first device to establish a WiFi connection with the second device. Therefore, the conventional operation method has poor operation convenience. Therefore, by adopting the implementation manner of the embodiment of the application, the function of establishing the WiFi connection between the second device and the AP device can be realized only by controlling the first device to be close to the second device or scanning the two-dimensional code of the second device by using the first device. Therefore, the operation mode of the embodiment of the application has strong operation convenience and can improve the use experience of the user.

The WiFi network connection method of the present application is exemplarily described below from a device perspective.

Fig. 5 illustrates a signaling interaction diagram of the WiFi network connection method 10. The WiFi network connection method 10 (hereinafter referred to as method 10) includes the following steps:

in step S11, the first device acquires identification information of the second device.

The identification information is used for identifying the second device, so that the second device can be distinguished from other devices in the coverage area of the AP device at least. In some embodiments, the identification information is, for example, a Media Access Control (MAC) address or a Serial Number (SN) of the second device. In other embodiments, the identification information is, for example, part of the second device MAC address, e.g., the last four bits of the second device MAC address. Alternatively, the identification information is, for example, partial information of the second device SN, for example, the last five bits of the second device SN. In some other embodiments, the identification information is, for example, information obtained by converting the MAC address or SN of the second device according to a preset algorithm, and the preset algorithm may be, for example, a hash algorithm.

In some embodiments, the first device and the second device are each provided with an NFC module. Based on this, after the user starts the NFC function of the first device and the second device, the first device and the second device may perform NFC communication to acquire the identification information of the second device. For example, the first device may send a request for obtaining the identification information to the second device through the NFC module of the first device. Then, the second device may encode the device identifier of the second device into an NFC packet in response to the acquisition request, and then transmit the NFC packet to the first device through the NFC module of the second device. Correspondingly, after the first device receives the NFC message, the first device decodes the NFC message to obtain the identification information. In this embodiment, the process of activating the NFC function and other human-computer interaction by the user and the process of other user operations are described in the embodiments illustrated in fig. 3B-1 to 3C, and are not described herein again.

Before step S11, in order to enable the first device to obtain the identification information using the NFC function, a first operation instruction may be preset in the first device, where the first operation instruction is used to trigger the first device to trigger the NFC module of the first device to send a request for obtaining the identification information after entering the radio frequency field of the NFC module of the second device. Correspondingly, a second operation instruction may be preset in the second device, where the second operation instruction is used to trigger the second device to encode the device identifier of the second device into an NFC packet after receiving the request for obtaining the identifier information, and then call an NFC module of the second device to send the NFC packet to the first device. In some embodiments, the first operation instruction may be preset in the memory 120 illustrated in fig. 2A. In other embodiments, the first operation instruction may be preset in the NFC module 130B illustrated in fig. 2A. Similarly, in some embodiments, the second operation instruction may be preset in the memory 220 illustrated in fig. 2B. In other embodiments, the second operation instruction may be preset in the NFC module 230B illustrated in fig. 2B.

In other embodiments, the identification information of the second device may be presented in the form of a two-dimensional code, and the first device may further acquire and identify the identification information of the second device by scanning the two-dimensional code. The two-dimensional code may be generated and displayed by the second device in response to an instruction input by a user, or may be generated when the second device leaves a factory. The interaction process between the user and the device in this embodiment is described in detail in the embodiments illustrated in fig. 4A to 4B-4, and is not described herein again.

Therefore, by adopting the implementation mode, the first device and the second device do not need to carry out complex communication or rely on a complex communication protocol, and the first device can acquire the identification information of the second device, so that the operation convenience of a user can be improved.

In step S12, the first device transmits a control instruction to the AP device.

Wherein the control instruction comprises identification information. The control instruction is used for triggering the AP equipment to send a WiFi connection instruction to the second equipment. The WiFi connection instruction comprises a first WiFi connection instruction and a second WiFi connection instruction. The first WiFi connection instruction is used for initiating WiFi connection to the second equipment, and the second WiFi connection instruction is used for triggering the second equipment to initiate WiFi connection.

In step S13, in response to the control instruction, the AP device establishes a WiFi connection with the second device.

Therefore, by adopting the implementation mode, the AP equipment can directly establish wifi connection with the second equipment according to the identification information without forwarding related signaling for establishing the wifi connection by the first equipment, so that the operation convenience of a user can be improved, and the network safety can be improved.

For example, in some embodiments, the AP device sends a first WiFi connection instruction to the second device, where the first WiFi connection instruction includes WiFi configuration information. The first WiFi connection instruction is used for triggering the second equipment to access the WiFi network corresponding to the WiFi configuration information. And then, the second device can send connection information to the AP device according to the wifi configuration information. Further, the AP equipment and the second equipment execute signaling interaction of wifi connection to complete wifi connection with the second equipment. In other embodiments, the AP device sends a second WiFi connection instruction to the second device. The second WiFi connection instruction does not include WiFi configuration information. The second WiFi connection instruction is used to trigger the second device to initiate a WiFi connection request to the AP device. And then, the second device responds to the second WiFi connection instruction and sends a request for acquiring the WiFi configuration information to the AP device. And then, the AP equipment sends the wifi configuration information to the second equipment. Further, the AP equipment and the second equipment execute signaling interaction of wifi connection to complete wifi connection with the second equipment. Subsequent communication procedures for establishing the WiFi connection between the AP device and the second device, as well as other communication information involved, are not described in detail herein.

In some embodiments, the AP device may send the WiFi connection instruction to the second device by means of unicast or WiFi Protected Setup (WPS). In other embodiments, the AP device may send the WiFi connection instruction to the second device in a broadcast or multicast manner. In this embodiment, the AP device may send the WiFi configuration information to the multiple devices, and correspondingly, the AP device may receive response information sent by the multiple devices. In order to accurately access the second device to the wireless network, after receiving the multiple pieces of response information, the AP device may detect whether the identification information corresponding to each piece of response information is the identification information of the second device. And if the identification information corresponding to the response information is the identification information of the second equipment, the AP equipment executes subsequent connection operation corresponding to the response information and establishes WiFi connection with the second equipment. If the identification information corresponding to the response information is not the identification information of the second device, the AP device does not perform any processing.

Further, after the AP device establishes the WiFi connection with the second device, it may also send notification information to the first device to notify the user that the second device has successfully accessed the wireless network. The effect of presenting the notification information is as shown in fig. 3F, and is not described in detail here.

To sum up, in the WiFi network connection method described in this embodiment of the application, the first device forwards the identification information of the second device to the AP device. And then, the AP equipment sends WiFi configuration information to the second equipment according to the identification information, so that the second equipment is accessed to a WiFi network. The first device communicates with the second device through an NFC or other method, for example, to obtain the device identifier of the second device, so that the operation convenience of the user can be improved. In addition, in the embodiment of the application, the WiFi configuration information is sent to the second device by the AP device, so that the security of the WiFi configuration information, that is, the network can be improved.

The WiFi network connection method of the present application is described below with reference to examples.

Illustratively, as shown in fig. 6, the first device is, for example, a smart phone 61, the second device is, for example, a smart sound box 62, and the AP device 300 is, for example, a router 63. Wherein, smart mobile phone 61 and smart speaker 62 all are provided with NFC module and wiFi module. The smart phone 61 end is installed with a router management APP, which is used for managing the router 63. The smartphone 61 has established a connection with the router 63, and the smart speaker 62 has not established a connection with the router 63.

Further, the WiFi network connection method 20 (hereinafter referred to as the method 20) includes the following steps:

in step S21, the user starts the NFC module of the smart phone 61, the router management APP, and the NFC module of the smart speaker 62.

The interaction process between the user and the smart phone 61 and the interaction process between the user and the smart speaker 62 are similar to the embodiments illustrated in fig. 3B-1 to 3B-3, and will not be described in detail here.

In step S22, the smart phone 61 sends an acquisition request to the smart sound box 62 through NFC.

Wherein, the obtaining request indicates to obtain the device identifier of the smart sound box 62. The acquisition request may be presented in the form of an NFC message.

In step S23, the smart sound box 62 sends identification information to the smartphone 61 through NFC.

In this embodiment, the identification information is, for example, the MAC address of the smart sound box 62. The MAC address of the smart speaker 62 is, for example, "M001". The identification information may be, for example, an NFC message encoded by the MAC address "M001".

For example, after the smart phone 61 receives the NFC message from the smart speaker 62, the NFC message may be decoded to obtain the MAC address "M001".

In step S24, the smartphone 61 sends a control instruction to the router 63.

Wherein the control instruction includes a MAC address "M001".

For example, after the smart phone 61 decodes the MAC address "M001" of the smart sound box 62, it may call a router management APP to generate an instruction for managing the router 63. After that, the smartphone 61 carries the MAC address "M001" in the instruction of the management router 63, and obtains a control instruction.

In step S25, in response to the control instruction, the router 63 sends a connection request to the smart sound box 62 in a unicast manner.

Wherein, the connection request includes WiFi configuration information. The connection request user triggers smart speaker 62 to access WiFi according to the WiFi configuration information.

It is noted that in some other embodiments, router 63 may send WiFi configuration information to smartspeaker 62 via broadcast, multicast, or WPS.

In step S26, the smart sound box 62 sends connection information to the router 63 in response to the WiFi configuration information.

In step S27, the router 63 establishes a WiFi connection with the smart sound box 62.

For example, after receiving the connection information, the router 63 may detect whether the identification information corresponding to the connection information is the MAC address "M001", and if the identification information corresponding to the connection information is "M001", it indicates that the device sending the connection information is the smart speaker 62, and establishes a WiFi connection with the device sending the connection information. Correspondingly, if the identification information corresponding to the connection information is not "M001", it indicates that the device sending the connection information is not the smart sound box 62, and the router 63 may not perform any processing.

In step S28, the router 63 transmits a notification of successful connection to the smartphone 61.

It is to be understood that the illustrated embodiment of the method 200 is merely illustrative and not restrictive of the embodiments of the application. In other embodiments, the operation steps of the WiFi network connection method may not be limited thereto. For example, the MAC address "M001" may be converted into a two-dimensional code, and the smartphone 61 may acquire the MAC address "M001" by scanning the corresponding two-dimensional code. And will not be described in detail herein.

It is to be understood that fig. 6 is only a schematic illustration and is not to be construed as limiting the embodiments of the present application. The embodiment of the application can also be applied to other similar implementation scenarios, for example, in other embodiments, the first device is a vehicle event data recorder, the second device is a vehicle-mounted air purifier, and the AP device is a wireless network card. And will not be described in detail herein.

In summary, with the implementation manner of the present application, the first device communicates with the second device, for example, in an NFC manner or the like, to obtain the device identifier of the second device, which can improve the operation convenience of the user, thereby improving the user experience. In addition, the WiFi configuration information is sent to the second device by the AP device, which can improve the security of the WiFi configuration information, i.e., the network.

The foregoing embodiments respectively introduce various aspects of the WiFi network connection method provided in this application from the perspective of the hardware structures, software architectures, and actions performed by the first device, the second device, and the AP device. Those skilled in the art will readily appreciate that the process steps described in connection with the embodiments disclosed herein may be implemented as hardware or a combination of hardware and computer software. Whether a function is performed as hardware or computer software drives hardware depends upon the particular application and design constraints imposed on the solution.
