Arduino Esp8266




Esp8266 Introduction:

This is WiFi serial transceiver module, based on ESP8266 SoC. ESP8266 module is a TTL “Serial to Wireless Internet” device. Providing your microcontroller has the ability to talk to a TTL serial device (most do) you’ll be in business. It is a highly integrated chip designed for the needs of a new connected world. It offers a complete and self-contained Wi-Fi networking solution, allowing it to either host the application or to offload all Wi-Fi networking functions from another application processor.

ESP8266 has powerful on-board processing and storage capabilities that allow it to be integrated with the sensors and other application specific devices through its GPIOs with minimal development up-front and minimal loading during runtime. Its high degree of on-chip integration allows for minimal external circuitry, and the entire solution, including front-end module, is designed to occupy minimal PCB area.

In this tutorial, we’ll use a seeeduino to control the ESP8266 WiFi module to request a static page from the internet. This is a basic use of TCP socket, for other usage, please refer to the AT command guide of the module.

The SOC has Integrated TCP/IP protocol stack
