The Bluetooth distribution network page is a page capable of triggering distribution network operation. The page can comprise a distribution network control, and distribution network operation can be triggered through the distribution network control. For example, the distribution network operation may be triggered by clicking, dragging, sliding, and the like on the distribution network control. Specifically, as shown in fig. 3, a "configure network" button is included in the bluetooth network distribution page, and the network distribution operation may be an operation triggered by clicking the "configure network" button.

The application program can be various application programs such as an instant messaging application, a social application, an office application, a game application and the like, for example, enterprise WeChat, personal WeChat, QQ, mini-games and the like. For example, as shown in fig. 4a, the application program is an instant messaging application, and the instant messaging application pops up a popup window containing a "scan control on the message page in response to a click operation on the add button, and the scan instruction is an instruction triggered by clicking the scan control in the popup window. And the distribution network initiating equipment responds to a scanning instruction triggered by clicking 'scanning' to perform distribution network graphic code scanning operation. As shown in fig. 4b, the distribution network initiating device scans the distribution network graphic code in a scanning frame displayed by the instant messaging application.

And S204, responding to the distribution network operation triggered on the Bluetooth distribution network page, and displaying a network selection page.

The distribution network operation is an operation for initiating a distribution network process, and may be an operation triggered by a distribution network control in a bluetooth distribution network page, or an operation triggered by sliding, dragging, and the like of the bluetooth distribution network page. For example, the distribution network operation is an operation triggered by sliding a bluetooth distribution network page, and the distribution network initiating device responds to the sliding operation of the bluetooth distribution network page and displays a network selection page through the instant messaging application.

The network selection page is a page showing a candidate network. The distribution network initiating device can select a wireless network which enables the device to be distributed to access from the candidate networks displayed on the network selection page. As shown in FIG. 5, the network selection page includes a plurality of candidate networks, which are respectively WechatWork-Staffwifi1-4.

In one embodiment, the distribution network graphic code scanning operation is an operation triggered by an instant messaging application, and the Bluetooth distribution network page is a page displayed by the instant messaging application. S204 specifically comprises: and the distribution network initiating equipment responds to the distribution network operation triggered on the Bluetooth distribution network page, and switches the Bluetooth distribution network page displayed by the instant messaging application into a network selection page.

And S206, when the target network is selected from the candidate networks displayed on the network selection page, generating a Bluetooth data packet based on the network connection information of the target network.

The network connection information is information required for enabling the device to be configured to access the target network, and comprises a network identifier, a network access password, an encryption type and the like of the target network. The network identifier is the name of the target network and is composed of numbers, letters, special symbols and the like. For example, the network identification may be WechatWork-Staffwifi1. The encryption type is a type for performing secure encryption on the target network, and includes types such as WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), WPA2, WPA3, WPA2 enterprise level, and WPA3 enterprise level. The distribution network initiating device may indicate the encryption type by a number, a letter, etc., for example, the WEP encryption type by a number "1", the WAP encryption type by a number 2, etc.

The Bluetooth data packet is a data packet obtained by encapsulating data based on a Bluetooth protocol. The bluetooth protocol may be a classic bluetooth protocol or a BLE bluetooth protocol, etc. The bluetooth packet may include a devicename field, and the distribution network initiating device may write the network connection information into the devicename field. In addition, the bluetooth packet may further carry a flag bit for identifying the bluetooth packet, where the flag bit may be a UUID (universal Unique Identifier).

In one embodiment, a plurality of candidate networks are presented in a network selection page. S206 specifically includes: the distribution network initiating equipment responds to the selection operation triggered in the network selection page and selects a target network; when the password is required to access the target network, the distribution network initiating equipment responds to the password input operation to obtain the network access password of the candidate network; the method comprises the steps that a distribution network initiating device obtains a network identifier and an encryption type of a target network and obtains a network access password input through password input operation; and generating a Bluetooth data packet based on the network identification, the encryption type and the network access password. For example, as shown in fig. 5, when a password is required to access a target network, the distribution network initiating device displays a password input box in response to a click operation triggered by the "network connection required" control, and acquires an access password input in the password input box. When the password is not needed to access the target network, the distribution network initiating device responds to the confirmation operation triggered by clicking the 'network connection without password' control, and confirms that the target network can be accessed without the password for accessing the network.

And S208, broadcasting the Bluetooth data packet so that the equipment to be networked is connected with a target network based on the network connection information and reports the networking state when receiving the Bluetooth data packet.

The Bluetooth data packet is broadcast by using the distribution network initiating device as a main device. And the equipment to be distributed is used as slave equipment for broadcast monitoring. The networking state is used for representing the state of the device to be networked, including a connected state and an unconnected state, connected to the target network.

In one embodiment, the bluetooth packet includes a first packet and a second packet; the network connection information comprises first network connection information and second network connection information; s208 specifically comprises: acquiring the broadcast time length for broadcasting the first data packet and the second data packet; through a Bluetooth network, a first data packet and a second data packet are sequentially broadcasted in a broadcasting time length, so that when the device to be networked receives the first data packet and the second data packet, first network connection information and second network connection information are respectively extracted from the first data packet and the second data packet, and the target network is connected based on the first network connection information and the second network connection information. For example, as shown in fig. 6, the broadcasting time is 15 seconds, first the first packet is broadcasted for 15 seconds continuously, then the second packet is broadcasted for 15 seconds continuously, and the cycle is repeated. Because the byte length of the network connection information is long, a single bluetooth data packet may not accommodate all the network connection information, so the distribution network initiating device may divide the bluetooth data packet into a first data packet and a second data packet, and transmit part of the network connection information through the first data packet and the second data packet, respectively, to avoid the loss of the network connection information due to the fact that the bluetooth data packet cannot accommodate all the network connection information when the network connection information is too long.

And S210, displaying the networking result of the equipment to be networked to the target network according to the networking state.

The networking result is used for indicating whether the device to be networked has successfully accessed the target network, including successful networking and failed networking. The network distribution initiating device can display the networking result on the device detail page, and when the networking result is successful, the device detail of the device to be distributed can be displayed on the device detail page.

In an embodiment, when the networking state is queried to be connected, the device serial number of the device to be networked is added to the device list of the instant messaging application to bind the device to be networked, so that other instant messaging applications cannot use the device to be networked. The device serial number may be obtained by decoding the distribution network initiating device from the distribution network two-dimensional code.

In one embodiment, S210 further comprises, before: in the process of broadcasting the Bluetooth data packet, inquiring the networking state reported by the equipment to be distributed, and starting a timer to time; s210 specifically includes: if the networking state reported by the equipment to be networked is inquired to be connected, the step of displaying the networking result of the equipment to be networked on the target network according to the networking state is executed; and if the networking state reported by the equipment to be networked is not connected, continuing to execute the step of broadcasting the Bluetooth data packet until the time counted by the timer reaches the preset time length.

The device to be distributed can report the networking state to a background server of the instant messaging application running in the device to be distributed, and the device to be distributed inquires the networking state reported by the device to be distributed from the background server through the running instant messaging application. When the networking state reported by the equipment to be networked is inquired to be connected, stopping broadcasting the Bluetooth data packet, and displaying the networking result of the equipment to be networked, which is successfully connected with the target network; and if the networking state reported by the inquired to-be-configured network equipment is still unconnected when the time counted by the timer reaches the preset time, displaying the networking result of the to-be-configured network equipment on the failure of the connection of the target network.

The timer times the time length of the distribution network initiating device broadcasting the Bluetooth data packet, and if the networking state reported by the to-be-distributed network device is not connected when the time length of the distribution network initiating device broadcasting the Bluetooth data packet reaches the preset time length, the situation that the to-be-distributed network device cannot be accessed to the target network through the network connection information is shown. At the moment, the distribution network initiating device stops broadcasting the Bluetooth data packet and displays the networking result of the target network connection failure of the to-be-configured network device, so that the problem that the distribution network initiating device still broadcasts the Bluetooth data packet for a long time when the to-be-configured network device cannot access the target network, time is wasted, and distribution network efficiency is reduced is solved.

In the embodiment, the Bluetooth distribution network page of the equipment to be distributed is displayed in response to the distribution network graphic code scanning operation, so that the distribution network process of the equipment to be distributed can be started through distribution network operation triggered in the Bluetooth distribution network page. When a target network is selected from the candidate networks displayed on the network selection page, a Bluetooth data packet is generated based on the network connection information of the target network, and then the Bluetooth data packet is broadcasted, so that the device to be networked can be connected with the target network based on the network connection information in the Bluetooth data packet when receiving the Bluetooth data packet. Therefore, the distribution network initiating device serves as a master device to perform Bluetooth broadcasting, the device to be configured serves as a slave device to perform broadcasting monitoring, the distribution network initiating device does not need to establish Bluetooth connection with the device to be configured, the Bluetooth data packet can be sent to the device to be configured through the Bluetooth broadcasting, and when the device to be configured cannot serve as the master device to establish Bluetooth connection with the distribution network initiating device due to the fact that a complete Bluetooth protocol is not supported, network connection information can be obtained and the device to be configured can be connected to a target network through the obtained network connection information.

The splicing data may be data obtained by directly splicing the network identifier, the network access password and the encryption type, or data obtained by splicing data generated based on the network identifier, the network access password and the encryption type. For example, the splicing data may be data obtained by splicing a hash value of the network identifier, an encrypted network access password, and an encryption type.

The first network connection information and the second network connection information are partial data in the splicing data. The lengths of the first network connection information and the second network connection information may be the same or different. For example, the first network connection information may be the first 20 bytes in the concatenated data, and the first network connection information may be the 21 st to 30 th bytes in the concatenated data. When the length of the bluetooth data packet cannot accommodate all the splicing data, the distribution network initiating device can divide the splicing data into first network connection information and second network connection information, and write the first network connection information and the second network connection information into different bluetooth data packets respectively.

S804, the first network connection information and the field mark corresponding to the first network connection information are packaged to obtain a first data packet; and encapsulating the second network connection information and the field mark corresponding to the second network connection information to obtain a second data packet.

The field mark is an identifier for distinguishing the bluetooth data packet, and comprises letters, numbers, special characters and the like. For example, the distribution network initiating device identifies the first packet with a field flag of "PS@" and the second packet with a field flag of "PE@". When receiving a data packet with a field mark of 'PS@', the device to be configured confirms that a first data packet is received and caches first network connection information extracted from the first data packet, and when receiving a data packet with a field mark of 'PE@', confirms that a second data packet is received and synthesizes second network connection information extracted from the second data packet and the cached first network connection information into network connection information and connects a target network based on the network connection information.

In one embodiment, the first data packet and the second data packet each include a device name field; the device name field includes a header subfield and a data subfield; the header subfield and the data subfield of the first data packet respectively store a field mark corresponding to the first network connection information and the first network connection information; and the header subfield and the data subfield of the second data packet respectively store the field mark corresponding to the second network connection information and the second network connection information.

Wherein the device name field is a field composed of partial bytes in the bluetooth packet and includes a header sub-field and a data sub-field. As shown in fig. 9, the bluetooth packet includes a device name field including a header subfield and a data subfield. The header subfield of the first data packet may store a field flag corresponding to the first network connection information, that is, a field flag "PS@" corresponding to the first data packet, and the data subfield of the first data packet may store the first network connection information; the header subfield of the second data packet may store a field flag corresponding to the second network connection information, that is, a field flag "PE@" corresponding to the second data packet, and the data subfield of the second data packet may store the second network connection information.

In the above embodiment, the distribution network initiating device divides the network identifier, the network access password, and the encrypted splicing data into the first network connection information and the second network connection information, and encapsulates the first network connection information and the second network connection information in different bluetooth data packets, so as to avoid that the length of the bluetooth data packet cannot accommodate all network connection information. Therefore, the network connection information can be sent to the equipment to be distributed through the broadcasted Bluetooth data packet, so that the equipment to be distributed is connected with the target network based on the network connection information.

In one embodiment, as shown in fig. 10, S802 specifically includes:

s1002, carrying out hash calculation on the network identifier to obtain a hash value of the network identifier.

The hash calculation is a calculation method for mapping input data into a data digest by a hash function. Common hash calculation algorithms include the MD4 (Message Digest) algorithm, the MD5 algorithm, the SHA-1 algorithm, and the like.

And S1004, encrypting the network access password to obtain the encrypted network access password.

The distribution network initiating device can encrypt the network access password through an asymmetric encryption algorithm or a symmetric encryption algorithm. The symmetric Encryption algorithm is an Encryption algorithm in which an Encryption key is the same as a decryption key, and includes an AES (Advanced Encryption Standard) algorithm, a DES (Data Encryption Standard) algorithm, an RC5 algorithm, a TDEA algorithm, and the like. The asymmetric encryption algorithm is an algorithm for respectively encrypting and decrypting by using different public keys and private keys, and comprises an RSA algorithm, an ECC (Error Correcting Code) algorithm, a D-H algorithm and the like.

In one embodiment, the network-accessing password is symmetrically encrypted by the network-accessing password using a CBC (Cipher Block Chaining) encryption mode of an AES encryption method, and the initial vector iv parameter used for encryption is a key used for encryption.

In one embodiment, after the network access password is encrypted, the network access password is converted into a visible character form through a base64 algorithm by the distribution network initiating device.

And S1006, splicing the hash value, the encrypted network access password and the encryption type to obtain spliced data.

Wherein, the splicing is to connect the data sequences in sequence. For example, the distribution network initiating device stores the encrypted type with a data sequence of 1 byte, stores the hash value with a data sequence of 16 bytes, and stores the encrypted network access password with a data sequence of 24 bytes. Then, after the hash value of 16 bytes is spliced into the encryption type of 1 byte, the encrypted network access password of 24 bytes is spliced into the hash value, and 41 bytes of spliced data is obtained.

In one embodiment, the distribution network initiating device splices the hash value, the encrypted network access password in the form of the visible character and the encryption type to obtain spliced data.

S1008, the splicing data is divided into first network connection information and second network connection information.

The distribution network initiating device divides the splicing data into two parts, namely first network connection information and second network connection information. Therefore, the first network connection information and the second network connection information can be respectively packaged in different Bluetooth data packets. The lengths of the first network connection information and the second network connection information may be the same or different.

In one embodiment, S1002 is followed by: selecting a character string with a preset digit number from the hash value as a target hash value of the network identifier; s1006 specifically includes: and splicing the target hash value, the encrypted network access password and the encryption type to obtain spliced data.

In particular, the distribution network initiating device may intercept a portion of the bytes from the hash value as a target hash value for the network identification, e.g., the distribution network initiating device intercepts 16 bytes from the hash value as a target hash value. The distribution network initiating device can sequentially connect the part of bytes intercepted from the hash value, the encrypted network access password and the encryption type to obtain splicing data.

In the above embodiment, the distribution network initiating device performs hash calculation on the network identifier, and maps the network identifier to a hash value with a shorter length, so that the utilization rate of bytes in the bluetooth data packet can be improved. Moreover, the network access password is encrypted, so that the network access password can be prevented from being stolen, and the security of the network access password is improved.

In one embodiment, S210 specifically includes: if the networking state reported by the equipment to be distributed is inquired to be connected, displaying an equipment detail page of the equipment to be distributed according to the networking state; and displaying the networking result of the equipment to be networked to the target network in a floating layer mode on the equipment detail page.

The device detail page is a page showing detailed information of the device to be networked, and may be a page shown in an application program of the device initiating the network distribution. For example, the distribution network initiating device presents a device details page through an instant messaging application. A float is a view with transparency superimposed on a page. The floating layer mode is a mode of displaying information through the floating layer. For example, as shown in fig. 11, the device detail page shows that the device to be networked is a screen box. If the network distribution initiating device inquires that the network connection state reported by the device to be connected is connected, the floating layer is displayed, and the network connection result of successful network connection is displayed in the displayed floating layer. And when the distribution network initiating device receives a query instruction triggered by clicking the device detail control in the device detail page, displaying the device detail information of the screen projection box.

Therefore, the user is informed that the equipment to be distributed has been accessed to the wireless network in time, and the efficiency of displaying the networking result is improved.

In one embodiment, the device to be distributed is a screen projection device; after S210, further comprising: responding to the screen-projecting graphic code scanning operation, and displaying a screen-projecting verification page in the instant messaging application; acquiring a screen projection verification code input in a screen projection verification page; and if the screen projection verification code passes the verification, the media data are sent to the screen projection equipment through the target network, so that the screen projection equipment performs screen projection display on the media data.

The distribution network initiating device broadcasts the Bluetooth data packet, so that the screen projection device is connected with a target network based on the network connection information when receiving the Bluetooth data packet. And after the screen projection equipment is successfully accessed to the target network, the media data sent by the instant messaging application can be received through the target network, and the media data is subjected to screen projection display.

The screen projection graphic code is used for projecting the screen of the screen projection equipment, and specifically can be a graphic code displayed by the to-be-configured network equipment through the display equipment. The screen-projection verification page is a page for inputting a screen-projection verification code. The screen-projection verification code is a code symbol used for verifying screen-projection operation, and specifically may be a number sequence, or a sequence composed of numbers, letters, and the like. For example, as shown in fig. 12, the screen shot verification page includes a screen shot verification code input area, a "start screen shot" trigger control, and a keyboard. The distribution network initiating device acquires the screen projection verification code input in the screen projection verification page, then verifies the screen projection verification code, and if the screen projection verification code passes verification, the media data is sent to the screen projection device through the target network, so that the screen projection device can perform screen projection display on the media data.

The screen projection can be that the media data are sent to the display device for display through the screen projection device, or the media data are projected to a curtain, a wall surface and the like for display through the screen projection device. For example, a screen projection device acquires media data played in a mobile terminal, and then sends the acquired media data to a display device (e.g., a television) for playing, so that the media data can be played on a larger screen.

In one embodiment, if the networking state reported by the device to be configured is found to be connected, the device initiating device for the distribution network adds the device serial number of the device to be configured to the device list of the instant messaging application, so as to bind the device to be configured.

And responding to the screen-projecting graphic code scanning operation by the distribution network initiating equipment, and displaying a screen-projecting verification page in the instant messaging application. And then comparing the screen projection verification code input in the screen projection verification page with the screen projection verification code displayed by the equipment to be configured, if the screen projection verification code input in the screen projection verification page is the same as the screen projection verification code displayed by the equipment to be configured, the screen projection verification code input by the user passes verification, and the distribution network initiating equipment sends the media data to the screen projection equipment through a target network so that the screen projection equipment performs screen projection display on the media data.

In the above embodiment, the distribution network device responds to the screen-projecting graphic code scanning operation, displays the screen-projecting verification page in the instant messaging application, and acquires the screen-projecting verification code input in the screen-projecting verification page. If the screen projection verification code passes the verification, the media data are sent to the screen projection equipment through the target network, so that the screen projection equipment can perform screen projection display on the media data. Therefore, the media data can be sent to the screen projection equipment through the target network for screen projection display, and the display efficiency of the media data is improved.

The operating system of the screen projection box 1506 is an android system of a kit kat version, only supports an incomplete bluetooth BLE protocol, can perform broadcast monitoring on a bluetooth data packet, and cannot perform broadcast transmission on the bluetooth data packet. The screen projection box 1506 is connected with the display device 1508 through an HDMI interface, when the screen projection box 1506 is powered on, whether a wireless network is connected is checked, and if the wireless network is not connected, the distribution network graphic code is displayed on the display device 1508.

As shown in fig. 16, the mobile terminal 1502 scans a distribution network graphic code through the instant messaging application, and in response to a distribution network graphic code scanning operation, displays a bluetooth distribution network page of the screen projection box 1506. The bluetooth network distribution page includes a network distribution control, and the mobile terminal 1502 displays a network selection page in response to a network distribution operation triggered by clicking the network distribution control. The network selection page shows a plurality of candidate networks, and the mobile terminal 1502 selects a target network from the candidate networks in response to a selection operation for the candidate networks, and then generates a bluetooth packet based on network connection information of the target network, where the bluetooth packet may include a first packet and a second packet. The network connection information comprises a network identifier, a network access password and an encryption type of the target network.

The mobile terminal 1502 performs MD5 hash calculation on the network identifier to obtain a hash value of the network identifier, and then intercepts a part of bytes from the obtained hash value and writes the part of bytes into the bluetooth data packet, for example, intercepts the first 16 bytes of the hash value and writes the first 16 bytes into the device name field of the bluetooth data packet. The mobile terminal symmetrically encrypts the network access password through a CBC (Cipher Block Chaining) encryption mode of an AES encryption method, and an initial vector IV parameter used for encryption is a secret key used for encryption.

If the wireless network is not connected, the screen projection box 1506 judges whether a Bluetooth network distribution is carried out or not, and if the Bluetooth network distribution is carried out, the two-dimensional code of the network distribution is displayed, so that the network distribution initiating device responds to the network distribution graphic code scanning operation triggered by the instant messaging application to initiate a network distribution process.

The screen projection box 1506 starts to monitor the bluetooth broadcast while displaying the distribution network graphic code, and when monitoring the bluetooth data packet broadcast by the mobile terminal 1502, extracts the device name field from the bluetooth data packet, and then extracts the network connection information from the device name field.

After receiving the networking state reported by the screen projection box, the background server of the instant messaging application responds to the query instruction sent by the mobile terminal 1502 through the client of the instant messaging application, and feeds back the networking state of the screen projection box 1506 to the mobile terminal.

After the screen projection box 1506 accesses the wireless network, the mobile terminal 1502 adds the device serial number of the screen projection box 1506 connected to the wireless network to the device list of the instant messaging application, and sends a binding success instruction to the screen projection box 1506, so that the screen projection box 1506 responds to the binding success instruction to display the screen projection graphic code.

The mobile terminal 1502 responds to a screen projection graphic code scanning operation triggered by the instant messaging application, displays a screen projection verification code input page, acquires a screen projection verification code input on the screen projection verification code input page, verifies the acquired screen projection verification code, and sends media data to a background server 1504 of the instant messaging application if the screen projection verification code passes the verification, and the background server 1504 forwards the media data to a screen projection box, so that the screen projection box 1506 sends the media data to a display device 1508 to be displayed, and specifically, the process that the mobile terminal 1502 projects the media data to the display device 1508 is shown in fig. 18.
