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.
ESP8266_WebSockets_HelloWorld
- Initiliaze ESP8266 with DHCP enabled
- Create a socketed connection with the above server
- It will send this message "n WebSocket Hello World over wifi", where n is the number of times it has sent.
- Websocket server echoes the string sent (backwards)
You can view the debug messages of this program by using a serial terminal set to 115200 baud.
