Description: Use two methods for network distribution, Espressif ESP-Touch and WeChat Airkiss.

Preparation: 1 NodeMCU or ESP8266 wifi module, ESP-Touch APP Android IOS

手机APP源码：https://github.com/EspressifApp/EsptouchForAndroid.git & https://github.com/EspressifApp/EsptouchForIOS.git

1，AT+CWMODE=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 intelligent 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, as shown in Figure 1. 

　　　　　　　　　Figure 1

5，AT+CWSTOPSMART 　　　　!!Regardless of whether the network configuration is successful or not, it is necessary to release the memory occupied by the quick connect, as shown in Figure 2 

6，AT+CIPSTATUS 　　　　　!!Query network connection status
