Problems with this networking method include: it requires a built-in BLE module and is expensive.

EasyConnect distribution technology: The Wi-Fi module is in the listening state and uses the multicast packet address encoding sent by the mobile APP. The Wi-Fi module parses the SSID and password based on the monitored information. Problems with this networking method include: poor compatibility, many monitoring signals, long time consumption, and high failure rate.

AP function distribution technology: After the Wi-Fi module is powered on, it is in AP mode, and then the mobile phone communicates with it as a station (STA), sending the SSID and password to the Wi-Fi module through the APP. After obtaining relevant information, the Wi-Fi module switches to site mode, connects to the target router, and connects to the cloud.

Detailed ways

The technical content of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

As shown in Figure 1, the first embodiment of the present invention provides a method for connecting a Wi-Fi module to the cloud to solve the problems of slow connection speed, high cost, and high cost of existing smart home appliances and smart home products when connecting to the cloud. Problems such as low connection success rate. This method uses the Wi-Fi module AP+site function to achieve stable and fast connection with the cloud.

Normally, the process of connecting the Wi-Fi module to the cloud is as follows:

After the Wi-Fi module is powered on, it is in AP mode, and then the mobile phone communicates with it as a station, sending the SSID and password to the module through the APP. After obtaining relevant information, the Wi-Fi module switches to site mode, connects to the target router, and connects to the cloud. The mobile phone also needs to be connected to the target router. Confirm through the cloud that the Wi-Fi module is connected to the target router.

The method provided by the first embodiment of the present invention at least includes the following steps:

Step S1: After the Wi-Fi module is powered on and starts up, it enters the AP+site coexistence state;

Among them, the working principle of the AP+ site is: when the module acts as an AP, it can also exist as an STA mode. For example, the WiFi module acts as an AP, allowing customers’ mobile phones or computers to access it, and at the same time, the module can also act as an STA. Connect to the router or upper server to upload data. It should be noted that the MAC address of the module when it is used as an AP and when it is used as a STA are different, so the MAC address of the module when it is used as an AP is different from the MAC address of the module when it is used as an STA when viewed inside the router.

In one embodiment of the present invention, the AP+site coexistence mode is implemented through the following steps:

Step S101: Set the local IP, gateway, subnet mask, and lower remote IP;

Step S102: Set the AP IP, gateway, subnet mask, and upper remote IP;

Step S103: Set local port and remote port;

Step S104: Set the name and password to connect to the remote AP;

Step S105: Set the name and password to establish the AP;

Step S106: Set the sending and receiving buffer;

Step S107: Initialize the baud rate;

Step S108: Disconnect (prevent already connected) WiFi.disconnect();

Step S109: Set to AP+STA mode WiFi.mode (WiFi_AP_STA);

Step S110: Set AP network parameters WiFi.softAPConfig();

Step S111: Set AP account password WiFi.softAP();

Step S112: Connect to the designated route WiFi.begin();

Step S113: Set local network parameters WiFi.config();

Step S114: Waiting for routing connection

Serial.println("pleasewait")WiFi.status()! =WL_CONNECTED;

Step S115:

Establish a UDP Server and listen to the specified port udp.begin(localPort);

Step S116: Display the IP address WiFi.localIP()WiFi.softAPIP();

Step S117: Read data

udp.read(buff, 255) udp.beginPacket(serverip, remoteport) udp.write(buff, 255) udp.endPacket();

Step S118: Clear the buffer data memset(buff, 0, 255).

Step S2: The Wi-Fi module obtains the SSID and password of the target router through the AP+site coexistence status;

Among them, the above method of obtaining the SSID and password of the target router includes at least the following steps:

S21: The Wi-Fi module reads the configuration table and determines whether it has been connected to the target router.

Among them, the configuration table is a functional module in the Wi-Fi module that stores the SSID and password of the connected target router. It is usually implemented using Flash memory.

If the target router has been connected, proceed to step S3; if the target router has not been connected, proceed to step S22.

S22: The mobile phone serves as a site and connects to the Wi-Fi module in AP mode to determine whether the connection is successful within the specified time.

If the connection fails within the specified time, go to step S5; if the connection is successful within the specified time, the mobile phone manually inputs the SSID and password of the target router on the APP and sends it to the Wi-Fi module, and goes to step S3.

Among them, because the Wi-Fi module does not have any external input interface, the above method successfully solves the problem of connecting the Wi-Fi module to the target router in this scenario. In addition, the above method does not add NFC, Bluetooth or other technology modules, thus solving the problem of connecting the Wi-Fi module to the target router without increasing the cost of the Wi-Fi module.

Step S3: After the Wi-Fi module obtains the SSID and password of the target router, it connects to the target router in site mode to determine whether the connection is successful.

Among them, because the Wi-Fi module is in the AP+site coexistence state at this time, it can be directly connected to the target router in site mode without switching from AP state to site state.

If the connection fails, clear the SSID and password of the target router obtained in step S2, and proceed to step S5; if the connection is successful, proceed to step S4.

Step S4: After the Wi-Fi module is successfully connected to the target router, connect to the cloud through the target router. Then the Wi-Fi module notifies the mobile phone in AP mode that the connection is successful, and saves the SSID and password of the target router to the configuration table;

Among them, the Wi-Fi module notifies the mobile phone of a successful connection in AP mode, eliminating the need to connect the mobile phone to the cloud, thereby solving the problem of long status confirmation due to the mobile phone connecting to the cloud.

Step S5: Power off the Wi-Fi module.

As shown in Figure 2, a second embodiment of the present invention provides a device for connecting a Wi-Fi module to the cloud, including a Wi-Fi module. The method by which the device implements the Wi-Fi module to connect to the cloud is the same as the method described in the first embodiment of the present invention, and will not be described again here.
