And after the Bluetooth modules of the board cards are successfully loaded, Bluetooth pairing is carried out. There are many ways to perform bluetooth pairing. For example, the second board searches for the bluetooth module of the first board through the bluetooth module, and automatically connects to the bluetooth module of the first board after searching for the bluetooth module of the first board. For another example, the first board searches for the bluetooth module of the second board through the bluetooth module, and after the bluetooth module of the second board is searched, the first board automatically establishes bluetooth connection with the second board.

EXAMPLE III
From the perspective of the board card receiving the Wi-Fi configuration data, a detailed description will be given of a specific embodiment of the method of the present invention.
as shown in fig. 5, a method for connecting multiple boards to a wireless network includes the steps of:

and S220, connecting the second board card to the Wi-Fi according to the Wi-Fi configuration data.
The Wi-Fi configuration data is data required by the card to connect to Wi-Fi, such as SSID (service set identifier), PASSWORD (personal authentication system) information and the like. In order to simplify the Wi-Fi connection step to the greatest extent, any one board card of the board cards may be used as a first board card for sending Wi-Fi configuration data, and the remaining board cards may be used as second board cards. For example, in an intelligent digital television, a TV board is used as a first board, and each extended application board is used as a second board. When the number of the board cards is large, in order to avoid the influence of the plurality of board cards sharing one Wi-Fi network on the network data exchange rate and the like, it can also be considered that a plurality of board cards are selected from the board cards to serve as first board cards, a user sets the selected board cards to enable the selected board cards to be connected to different Wi-Fi networks, then the selected board cards respectively transmit respective Wi-Fi configuration data to corresponding second board cards through Bluetooth, and the Wi-Fi connection of the second board cards is achieved, so that the Wi-Fi connection steps are simplified to a certain extent, and the network data exchange rate and the like can be guaranteed.
before each board card is connected with the Wi-Fi, the board cards need to be powered on and started up firstly, and then the Wi-Fi modules and the Bluetooth modules are loaded. And after the Bluetooth modules of the board cards are successfully loaded, Bluetooth pairing is carried out. For example, in an embodiment, before receiving Wi-Fi configuration data sent by the bluetooth module after the first board is successfully connected to Wi-Fi, the method may further include:
After a second board card is powered on and started, loading a Bluetooth module of the second board card;
searching the Bluetooth module of the first board card through the Bluetooth module of the second board card;
and when the Bluetooth module of the first board card is successfully searched, automatically connecting the Bluetooth module of the second board card with the Bluetooth module of the first board card.
the Bluetooth pairing mode does not need to input a pairing key, so that the situation that a user needs to input the pairing key one by one when the Wi-Fi sharing connection is realized is avoided, and the simple and convenient Wi-Fi connection is really realized. The user can regard as the first integrated circuit board that sends Wi-Fi configuration data the mainboard card in the fixed equipment, for example regard as first integrated circuit board with the TV integrated circuit board in the smart TV, then when having new integrated circuit board to insert, set up the bluetooth search object of new integrated circuit board and be this first integrated circuit board, carry out bluetooth promptly by oneself after searching for first integrated circuit board and pair simple and convenient.
after the first board card is successfully connected to the Wi-Fi according to the setting of the user, corresponding Wi-Fi configuration data can be inserted into a Media Payload data packet and then sent to the second board card through Bluetooth. If the first board card inserts the Wi-Fi configuration data into a Media Payload data packet when sending the Wi-Fi configuration data, and then a CP (packet control protocol) header, an MP (MP packet header) header and an L2CAP header are sequentially added, after receiving the Wi-Fi configuration data, the second board card needs to sequentially remove the L2CAP header, the MP header and the CP header, then the Wi-Fi configuration data inserted into the Media PL data packet is obtained, Wi-Fi connection is automatically performed according to the Wi-Fi configuration data, and a user does not need to perform Wi-Fi connection of the second board card any more, so that the operation is simple and convenient.

and the second Wi-Fi module 220 is used for connecting the second board to Wi-Fi according to the Wi-Fi configuration data.
Before each board card is connected with the Wi-Fi, the board cards need to be powered on and started up firstly, and then the Wi-Fi modules and the Bluetooth modules are loaded. For example, in one embodiment, before the second bluetooth module 210 receives Wi-Fi configuration data sent by the bluetooth module after the first board is successfully connected to Wi-Fi, the second bluetooth module is further configured to load the bluetooth module of the second board after the second board is powered on and started, search for the bluetooth module of the first board through the bluetooth module of the second board, and automatically connect the bluetooth module of the second board and the bluetooth module of the first board when the bluetooth module of the first board is successfully searched.
the Bluetooth pairing mode does not need to input a pairing key, so that the situation that a user needs to input the pairing key one by one when the Wi-Fi sharing connection is realized is avoided, and the simple and convenient Wi-Fi connection is really realized. The user can regard as the first integrated circuit board that sends Wi-Fi configuration data the mainboard card in the fixed equipment, for example regard as first integrated circuit board with the TV integrated circuit board in the smart TV, then when having new integrated circuit board to insert, set up the bluetooth search object of new integrated circuit board and be this first integrated circuit board, carry out bluetooth promptly by oneself after searching for first integrated circuit board and pair simple and convenient.
After the first board card is successfully connected to the Wi-Fi according to the setting of the user, corresponding Wi-Fi configuration data can be inserted into a Media Payload data packet and then sent to the second board card through Bluetooth. If the first board card inserts the Wi-Fi configuration data into a Media Payload data packet when the first board card sends the Wi-Fi configuration data, a CP packet header, an MP packet header and an L2CAP packet header are sequentially added. After receiving the Wi-Fi configuration data, the second bluetooth module 210 needs to sequentially remove the L2CAP packet header, the MP packet header, and the CP packet header, and then obtains the Wi-Fi configuration data inserted into the Media PL data packet, and the second Wi-Fi module 220 automatically performs Wi-Fi connection according to the Wi-Fi configuration data, so that the user does not need to perform Wi-Fi connection of the second board card any more, and the operation is simple and convenient.
