1, AT+CWMODE_DEF=1 　　　!! Configure the WiFi module to work in single STA mode, and save the configuration in flash

2, AT+CWAUTOCONN=1 　　　!! Enable automatic connection to AP after power on

3, AT+CWSTARTSMART=3 　　!! Support ESP-Touch and Airkiss smart distribution network

4. Connect the mobile phone to the AP that needs network configuration, open the mobile APP ESP-Touch, enter the password, click OK, and wait for the network configuration to succeed, see Figure 1

　　　　　　　　　Figure 1

5, AT+CWSTOPSMART 　　　　!! Regardless of whether the network configuration is successful or not, you need to release the memory occupied by the quick connect, see Figure 2

6, AT+CIPSTATUS 　　　　　!! Check the network connection status
