Introduction

This is a basic Hello World program for interfacing the ESP8266 chip with websockets. It will connect and send a message to this web socket server location: 192.168.1.20 : 8888.

You can find the python server code here.

  1. Initiliaze ESP8266 with DHCP enabled
  2. Create a socketed connection with the above server
  3. It will send this message "n WebSocket Hello World over wifi", where n is the number of times it has sent.
