Warning!

This library has been discarded. A new library named WeeESP8266 is recommended, which is more easy-to-use for users. WeeESP8266 can be downloaded at https://github.com/itead/ITEADLIB_Arduino_WeeESP8266.

ESP8266 library

When you use with UNO board, uncomment the follow line in uartWIFI.h.

#define UNO

When you use with MEGA board, uncomment the follow line in uartWIFI.h.

#define MEGA

Connection:

When you use it with UNO board, the connection should be like these:

ESP8266_TX->D0

ESP8266_RX->D1

ESP8266_CHPD->3.3V

ESP8266_VCC->3.3V

ESP8266_GND->GND

FTDI_RX->D3 //The baud rate of software serial can't be higher that 19200, so we use software serial as a debug port

FTDI_TX->D2

When you use it with MEGA board, the connection should be like these:

ESP8266_TX->RX1(D19)

ESP8266_RX->TX1(D18)

ESP8266_CH_PD->3.3V

ESP8266_VCC->3.3V

ESP8266_GND->GND

When you want to output the debug information, please use DebugSerial. For example,

DebugSerial.println("hello");

Attention

Note1: The size of message from ESP8266 is too big for arduino sometimes, so the library can't receive the whole buffer because
the size of the hardware serial buffer which is defined in HardwareSerial.h is too small.

Open the file from \arduino\hardware\arduino\avr\cores\arduino\HardwareSerial.h. See the follow line in the HardwareSerial.h file.

#define SERIAL_BUFFER_SIZE 64

The default size of the buffer is 64. Change it into a bigger number, like 256 or more.

The SRAM size of mega is bigger than UNO's, so it is better to use MEGA board to communicate with ESP8266.

BUG: When you use this library and receive the http package, it might miss some characters because the library can't process so much data in the same time.
