ESP8266-Based Serial WiFi Shield for Arduino is designed and developed by Shenzhen Doctors of Intelligence & Technology (SZDOIT). The shield is designed based on esp8266 by Espressif Systems, pin-compatible with Arduino UNO/Mega2560 DevBorad.

The serial wifi shield has the following features:
1、WiFi module is industrial-grade chips ESP8266, which is ESP-12E with metal shield, strong anti-interference ability;
2, Shield is pin-compatible with Arduino Uno, Mega2560 and other control board. A voltage converter chip is used to deal with 3.3V (Esp8266) and 5V (Arduino);
3, Dual DIP switches is used for serial ports so that this module shield can be used alone as an Arduino Uno expansion board, and also be used as ESP8266 expansion board;
4, Serial data is transported to WiFi device transparently, and vice versa. Arduino program does not need any configuration;
5, WebServer is developed to configure WiFi parameters and serial port parameters;
6, The module shield can be used as an independent ESP8266 development board. for instance, downloading the official AT commands firmware, NodeMCU open source firmware can be used;
7, The module shield also can be used as stand-alone expansion board for Arduino Uno.

Arduino core for ESP8266 WiFi chip

This project brings support for ESP8266 chip to the Arduino environment. It lets you write sketches using familiar Arduino functions and libraries, and run them directly on ESP8266, no external microcontroller required.
ESP8266 Arduino core comes with libraries to communicate over WiFi using TCP and UDP, set up HTTP, mDNS, SSDP, and DNS servers, do OTA updates, use a file system in flash memory, work with SD cards, servos, SPI and I2C peripherals.

Question 1: How to restore factory settings. Here shows two ways:




      One: Connect the WiFi, and enter the web interface settings, use “FactoryDefault” button.



      Or:  (For Doit ESp8266 WiFi expansion board, nodemcu compatible development board) . Press “Flash” button more than 3 seconds (the LED lights flash) and restore the default factory settings



 

Question 2:  How does it work about AP and STA
  
    
     In AP mode, SSID , password, local ip address, subnet mask and gateway address can be set
   
     In STA mode, the router wifi SSID can be scanned.



Question 3: How does it work about serial communication.
 


     Networks can be set to tcp server / client, udp server / client
    
     When Client mode is used, domain and IP can be set to a remote address.
     When data receiving or sending, LED lights flash.

 
Question4: How to download a new firmware.
 
    
     Step 1: Use the download software, shown as follows.
   
    Note: Two bin files should be used. One is “ eagle.flash.bin”, whose download address is 0x00000. The other is “eagle.irom0text.bin”, whose download address is 0x40000. All configuration is shown in the follow picture.


    

     Step 2: Choose the correct serial port number. Then, press “FLASH” button, and press “RESET” button. OK, the download process will be started after press “START”.
 
     Step 3: Enjoy it!

WiFiMCU


WiFiMCU is developed based on EMW3165 module produced by MXCHIP.INC. A Lua interpreter is builded inside with hardware support. A light weight file system and socket protocols can help to realize IoT development easily and quickly. Basically, you can load this on your device and then run Lua scripts on it with nothing more than a terminal connection. 
Enjoy it!

• Based on Lua 5.1.4 (package, string, table, math modules)
• Build-in modules: mcu,gpio, timer, wifi, net, file, pwm, uart, adc.
• Modules to be builded: spi, i2c, 1-wire, bit, mqtt...
• Integer version provided
• Free memory >48k bytes
