The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
Fig. 1A is a schematic diagram illustrating an operation scenario between a smart speaker and a terminal. As shown in fig. 1A, the terminal 100 and the smart sound box 200 may communicate with each other in a wireless manner.
Wherein, terminal 100 is configured to control smart sound box 200, which may receive an operation instruction input by a user, and convert the operation instruction into an instruction recognizable and responsive by smart sound box 200, and play an intermediary role in interaction between the user and smart sound box 200. Such as: the user responds to the operation of voice addition and subtraction by operating the voice addition and subtraction keys on the terminal 100.
The terminal 100 may also be a smart device, such as a mobile terminal, a tablet computer, a notebook computer, etc. For example, smart sound box 200 is controlled using an application running on the smart device. The application program may provide various controls to a user through an intuitive User Interface (UI) on a screen associated with the smart device through configuration.
A block diagram of the configuration of smart sound box 200 is illustrated in fig. 1B. As shown in fig. 1B, the smart sound box 200 includes a controller 210, a communicator 220, a sound output module 230, and a power supply 240.
The controller 210 includes a Random Access Memory (RAM)211, a Read Only Memory (ROM)212, a processor 213, a communication interface, and a communication bus. Controller 210 is used to control the operation of smart sound box 200, as well as the communication cooperation between the internal components, external and internal data processing functions.
The communicator 220 enables communication of data signals with the terminal 100 under the control of the controller 210. Such as: the smart sound box 200 transmits the data signal to the terminal 100 via the communicator 220, and the smart sound box 200 may receive the data signal and the control signal transmitted by the terminal 100 via the communicator 220.

Optionally, smart sound box 200 further includes a power supply 240 for providing operational power support to the various components of smart sound box 200 under the control of controller 210. In the form of a battery and associated control circuitry.
Referring to fig. 2A, an embodiment of the present application provides a network distribution method for an intelligent sound box, including:
the intelligent sound box starts a distribution network;
the terminal starts a distribution network interface, searches the Bluetooth of the intelligent sound box and initiates connection with the intelligent sound box;
the terminal can be a mobile phone, a computer and an ipad.
After the intelligent sound box is successfully connected with the terminal, other terminals cannot be connected with the intelligent sound box;
the intelligent sound box sends a request for acquiring the maximum transmission unit to the terminal;
and after receiving the request sent by the intelligent sound box, the terminal responds to the request for obtaining the maximum transmission unit.
The terminal may or may not reply to the limit size of the maximum transmission unit of the smart speaker.
For example, in the andorid system, before using bluetooth (ble) to transmit data, the limit of MAXIMUM TRANSMISSION UNIT (MTU) of the andorid device can be obtained, which is generally 512 bytes. And the limited size of the maximum transmission unit of the intelligent sound box can not be replied to part of the terminals and the system.
A user clicks a button for acquiring a wifi list on a terminal, and the terminal sends a request for acquiring the wifi list;
the intelligent sound box receives a wifi list acquisition request sent by the terminal, and determines a transmission mode according to whether the terminal replies to the maximum transmission unit.
If the smart sound box does not receive the limitation of the maximum transmission unit replied by the terminal, the existing mode usually adopts the default transmission size transmission of ble transmission, and the default transmission size of ble transmission is 23 bytes. When the default MTU is used for transmitting data, it takes a long time to acquire the wifi list, so that it is impossible to acquire the wifi list by using the default MTU, and a user cannot select wifi. Aiming at the condition that the terminal does not reply the maximum transmission unit, the method and the device use a BLE _ WIFI self-adaptive transmission algorithm to transmit WIFI list data, and can meet the acquisition speed of a WIFI list. The specific method comprises the following steps:
referring to fig. 2B, fig. 2B is a flowchart of the BLE _ WIFI adaptive transmission algorithm.
When the intelligent sound box does not receive the limitation of the maximum transmission unit replied by the terminal, obtaining available wifi information within a preset range;
establishing a wifi list according to wifi information;
and calculating the data size of the wifi list, and transmitting the data size of the wifi list to the terminal according to the default transmission size of ble.
And the terminal receives and records the data size of the wifi list transmitted in the ble default transmission size.
For example: the data size of the wifi list is obtained through calculation of the intelligent sound box, namely the data size of the wifi list before being transmitted to the terminal is 1000 bytes, and the data of 1000 bytes is transmitted to the terminal in 23 byte transmission size.
If the data size of the wifi list is smaller than the preset byte, the preset byte can be 512 bytes, the data of the wifi list is transmitted to the terminal according to the first forward data size in the wifi list transmission data queue, and the wifi list transmission data queue comprises the data sizes which are arranged from small to large.
The wifi list transmission data queue may be {70,134,262,518}, and the unit is byte. The value of the wifi list transmission data queue represents the size of a data packet transmitted at one time. According to the structure of ble transport packets, each transport packet is composed of a header (2 bytes), a payload, and a trailer (4 bytes), so the queue data is composed of: the first 2 bytes are packet headers, the effective data loads are respectively 64, 128, 256 and 512 bytes, and the last 4 bytes are packet tails, so that a wifi list transmission data queue is formed and is {70,134,262,518 }.
The terminal continuously receives data of the wifi list sent by the intelligent sound box until an end mark is received; calculating the data size of the received wifi list; if the data size of the wifi list transmitted by the intelligent sound box is not consistent with the data size of the wifi list calculated by the terminal, sending a packet loss message to the intelligent sound box; and if the data size of the wifi list transmitted by the intelligent sound box is consistent with the data size of the wifi list calculated by the terminal, displaying the wifi name in the wifi list and sending a message which does not lose the packet to the intelligent sound box. After the user checks the available wifi in the wifi list, any wifi in the list is selected, the password corresponding to the wifi is input, and the terminal sends the service set identification and the password of the wifi selected by the user to the intelligent sound box.
If the intelligent sound box receives a packet loss message sent by the terminal, judging whether the size of the transmission data is the last value of a wifi list transmission data queue;
and judging the last value of the wifi list transmission data queue according to the direction of the wifi list transmission data queue. The wifi list transmit data queue is specifically 70,134,262,518 because the start is transmitted 70 bytes in forward first data size, then the last value is 518 bytes in forward last value.
And if the transmission data size is not the last value of the wifi list transmission data queue, retransmitting the data of the wifi list to the terminal by using the next forward data size in the wifi list transmission data queue.
And if the size of the transmission data is the last value of the transmission data queue of the wifi list, sending a message that the acquisition of the wifi list fails to be obtained to the terminal.
And if the intelligent sound box receives the message which is not lost and sent by the terminal, receiving the service set identification and the password of the wifi selected by the user. Connecting a wireless network using the received service set identifier and password; and after the connection is successful, reporting the networking successful state to the terminal.
The terminal enters a home page to display media resources and the like.
For example: the wifi list transmission data queue is specifically {70,134,262,518}, the size of data transmitted to the terminal wifi list by the intelligent sound box is 500 bytes, and the intelligent terminal transmits the data of the wifi list to the terminal in 70 bytes. If the terminal receives all transmitted data and calculates that the size of the received data is 500 bytes, the data size transmitted to the wifi list of the terminal by the intelligent sound box is consistent with the size of the data calculated by the terminal, the terminal sends a packet loss-free message to the intelligent sound box, and the intelligent sound box receives a service set identifier and a password of wifi selected by a user. Connecting a wireless network using the received service set identifier and password; and after the connection is successful, reporting the networking successful state to the terminal. The terminal enters the home page to display the media resources. If the terminal receives all transmitted data and calculates that the size of the received data is 490 bytes, the data size transmitted by the intelligent sound box to the terminal wifi list is inconsistent with the data size calculated by the terminal, and the terminal sends a packet loss message to the intelligent sound box. Because 70 is not the last data size of the wifi list transmission data queue, the smart sound box retransmits the data of the wifi list to the terminal with a 134-byte transmission size until receiving the message that the packet is not lost sent by the terminal, or retransmits the data of the data list to the terminal with a 518-byte transmission size of the last data size of the wifi list transmission data queue, the message that the packet is not lost sent by the terminal is still not received, the smart terminal sends the message that the wifi list acquisition fails to the terminal, the terminal displays the message that the distribution network fails, and the user can try to distribute the network again.
If the data size of the wifi list is not smaller than the preset byte, the preset byte can be 512 bytes, and the data of the wifi list is transmitted to the terminal by the first reverse data size in the wifi list transmission data queue.
The wifi list transmission data queue may be {70,134,262,518}, and the unit is byte. The value of the wifi list transmission data queue represents the size of a data packet transmitted at one time. According to the structure of ble transport packets, each transport packet is composed of a header (2 bytes), a payload, and a trailer (4 bytes), so the queue data is composed of: the first 2 bytes are packet headers, the effective data loads are respectively 64, 128, 256 and 512 bytes, and the last 4 bytes are packet tails, so that a wifi list transmission data queue is formed and is {70,134,262,518 }.
The terminal continuously receives data of the wifi list sent by the intelligent sound box until an end mark is received; calculating the data size of the received wifi list; if the data size of the wifi list transmitted by the intelligent sound box is not consistent with the data size of the wifi list calculated by the terminal, sending a packet loss message to the intelligent sound box; and if the data size of the wifi list transmitted by the intelligent sound box is consistent with the data size of the wifi list calculated by the terminal, displaying the wifi name in the wifi list and sending a message which does not lose the packet to the intelligent sound box. After the user checks the available wifi in the wifi list, any wifi in the list is selected, the password corresponding to the wifi is input, and the terminal sends the service set identification and the password of the wifi selected by the user to the intelligent sound box.
If the intelligent sound box receives a packet loss message sent by the terminal, judging whether the size of the transmission data is the last value of a wifi list transmission data queue;
and judging the last value of the wifi list transmission data queue according to the direction of the wifi list transmission data queue. The wifi list transmit data queue may be 70,134,262,518 since transmission begins with the reverse first data size of 518 bytes, then the last value is the reverse last value of 70 bytes.
And if the size of the transmission data is not the last value of the wifi list transmission data queue, retransmitting the data of the wifi list to the terminal by using the next reverse data size in the wifi list transmission data queue.
And if the size of the transmission data is the last value of the transmission data queue of the wifi list, sending a message that the acquisition of the wifi list fails to be obtained to the terminal.
And if the intelligent sound box receives the message which is not lost and sent by the terminal, receiving the service set identification and the password of the wifi selected by the user. Connecting a wireless network using the received service set identifier and password; and after the connection is successful, reporting the networking successful state to the terminal.
The terminal enters a home page to display media resources and the like.
For example: the wifi list transmission data queue can be {70,134,262,518}, the size of data transmitted to the terminal wifi list by the intelligent sound box is 3000 bytes, and the intelligent terminal transmits data of the wifi list to the terminal in size of 518 bytes. If the terminal receives all transmitted data and the size of the calculated data is 3000 bytes, the size of the data transmitted to the wifi list of the terminal by the intelligent sound box is consistent with the size of the data calculated by the terminal, the terminal sends a packet loss-free message to the intelligent sound box, and the intelligent sound box receives a service set identifier and a password of wifi selected by a user. Connecting a wireless network using the received service set identifier and password; and after the connection is successful, reporting the networking successful state to the terminal. The terminal enters the home page to display the media resources. If the terminal receives all transmitted data and calculates the data size to be 2800 bytes, the data size transmitted to the terminal wifi list by the intelligent sound box is inconsistent with the data size calculated by the terminal, and the terminal sends a packet loss message to the intelligent sound box. Because 518 is not the last value of the wifi list transmission data queue, the smart sound box retransmits the data of the wifi list to the terminal in 262 bytes transmission size until a non-packet-lost message sent by the terminal is received, or after the data of the wifi list transmission data queue is retransmitted in 70 bytes transmission size to the terminal, the non-packet-lost message sent by the terminal is still not received, the smart terminal sends a message that the wifi list acquisition fails to the terminal, the terminal displays a message that the distribution network fails, and the user can try to distribute the network again.
If the intelligent sound box receives the limitation of the maximum transmission unit replied by the terminal, acquiring available wifi information within a preset range; establishing a wifi list according to wifi information; and transmitting the data of the wifi list according to the transmission size of the maximum transmission unit.
For example, if the maximum transmission unit of the reply of the terminal is limited to 512 bytes, the wifi list data is transmitted in 512 byte transmission size.
The terminal receives an available wifi list sent by the intelligent sound box, and wifi names in the wifi list are displayed.
And the user selects any wifi in the list after checking the available wifi, and inputs the password corresponding to the wifi.
And the terminal sends the service set identification and the password of the wifi selected by the user to the intelligent sound box.
The intelligent sound box is connected with a wireless network by using the received service set identification and the password; and after the connection is successful, reporting the networking successful state to the terminal.
The terminal enters the home page to display the media resources.
The intelligent sound box is mainly dependent on the network, when the intelligent sound box is used for the first time, the network needs to be configured for the intelligent sound box through the terminal app, and in order to optimize user experience, no matter whether the app on the Android or IOS mobile phone operating system is operated, a user can freely select the network to configure the network of the sound box.

The intelligent sound box receives a service set identifier and a password of wifi selected by a user; and connecting the wireless network according to the service set identifier and the password. According to the method and the device, in the process of a distribution network, when the MTU condition of the terminal is not acquired, the data transmission of the default maximum transmission unit of the ble can be avoided, the device compatible with different systems can realize the free network configuration of a user by realizing the function of acquiring a wifi list, the terminal is not required to be connected with wifi in advance or the wifi connected with an intelligent connection terminal is not required, and the user experience is enhanced.
