When the duration is longer than the preset storage duration, the slave device sends a Wi-Fi information request message to the master device through the first transmission channel. After receiving the Wi-Fi information request message, the master device sends Wi-Fi information to the slave device through the first transmission channel. -Fi info.

Further, in the case that the slave device determines that the first distance is not less than the preset distance, the slave device continues to use the existing AP scanning method, and actively initiates scanning to obtain access point information.

In an optional embodiment, after receiving the Wi-Fi information in response to the Wi-Fi information request message from the device, the Wi-Fi information is updated to the pre-stored Wi-Fi information, and based on the updated pre-stored Wi-Fi information - Fi information selects the first access point, searches for the connection information of the first access point from the updated pre-stored Wi-Fi information, and connects the access point according to the connection information of the first access point.

It should be noted that, for the process of searching for the connection information of the first access point from the pre-stored Wi-Fi information, reference may be made to searching for the connection information of the first access point from the updated pre-stored Wi-Fi information.

Exemplarily, the process of scanning an access point from a device is shown in FIG. 4 ,

1. Obtain the first distance between the slave device and the master device;

2. When the first distance is greater than the preset distance threshold, the slave device actively initiates scanning;

3. In the case that the first distance is not greater than the preset distance threshold, the slave device determines whether the Wi-Fi information stored in the device has expired;

4. In the case of judging that the Wi-Fi information stored in the slave device has expired, request the Wi-Fi information from the master device, and after receiving the Wi-Fi information sent by the master device, send the Wi-Fi Update the information to the internal storage, go to 6;

5. If it is determined that the Wi-Fi information stored in the slave device has not expired, go to 6;

Here, The connection parameter can be the connection result or the signal quality of the access point. When the connection of the access point currently connected by the master device fails or the signal quality of the access point is lower than the quality threshold, it indicates the connection parameter of the access point currently connected by the master device. If the preset connection condition is not met, at this time, the slave device selects the first access point according to the updated pre-stored Wi-Fi information or the channel-related information in the pre-stored Wi-Fi information. Specifically, the slave device determines the optimal first access point according to information such as channel, link-speed, bss-load, and RSSI.

It can be understood that the master device sends the Wi-Fi information scanned, stored and/or currently connected to the slave device through the first transmission channel with the slave device, and the slave device is directly based on the Wi-Fi information sent by the master device. The access point connection is realized without traversing all Wi-Fi channels, which improves the Wi-Fi connection speed of the device and reduces the power consumption of the Wi-Fi module due to scanning.

Exemplarily, as shown in FIG. 6 , the process of connecting an access point from a device specifically includes:

1. From the device, select the access point 1 that the master device is connecting to;

2. The slave device determines whether the access point 1 is successfully connected or whether the signal quality of the access point 1 is greater than a preset threshold;

3. When the connection of access point 1 fails or the signal quality of access point 1 is lower than the preset threshold, select the optimal access according to the channel/link-spped/bss-load/rssi and other information in the Wi-Fi information point 2;

4. Directly initiate an access point connection according to the channel/ssid/password of access point 2;

5. In the case that the access point 1 is successfully connected or the signal quality of the access point 1 is greater than the preset threshold, it indicates that the connection is successful.

In an optional embodiment, based on the foregoing embodiment, after S101, that is, after the slave device connects to the access point based on the Wi-Fi information, the slave device may connect to the first access point based on the first access point. After the access point completes the data transmission, the Wi-Fi connection of the first access point is disconnected. In this case, the monitoring hold of the access point is not required, and the system power consumption of the slave device can be reduced.

In another optional embodiment, based on the above embodiment, after S101, that is, after the slave device realizes the access point connection based on the Wi-Fi information, the slave device also performs the process of monitoring the access point, as shown in Fig. 7 as shown,
