ESP8266 & ESP32 User Guide


Note: This page mainly uses AT commands to develop wifi modules. 


一. STM32 project example of ESP8266 

AT command project: STM32AT command project of ESP8266

Instructions for use document: unzip the project compression package to obtain

Tencent Cloud AT Command Control Light Project: stm32 docking with Tencent Cloud Control Light.zip

Ali Feiyan AT command light control project: STM32 Ali Feiyan AT command light control project of ESP8266 


二. Smart configuration example (Smartconfig) 


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


Method 1:ESP-Touch


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 


            Figure 2 


Method 2:Airkiss


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,Open WeChat, follow the WeChat public account "Anxinke Technology", click wifi configuration, click start configuration, enter the password, click connect, see Figure 3 


        Figure 3 

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 

6,AT+CIPSTATUS       !!Query the network connection status, as shown in Figure 4 


          Figure 4
