A big step forward in attaining high speed for real-time web technology.

Real-time client-server communication is achievable.

Two-way communication over a single Transmission Control Protocol (TCP) connection.

key features of WebSocket Communication Protocol The servers can handle both the HTTP and the WebSocket connections on the same port by sending data to all the clients. Through an upgraded header, the server gets to know that the request deals with a WebSocket connection. Firstly, the client sends an HTTP request to the server. The simple WebSocket handshake process is shown in the picture above. The server will update all the connected clients (smartphones, tablets, computers, laptops, etc.) instantaneously when the state of the onboard LED will change. Therefore, in this guide, our objective is to show you the responsiveness of a web server created with WebSocket. It offers extremely fast response rate by using two-way communication between the client-server as compared to the simple HTTP protocol. It uses the handshaking mechanism to ensure that the server is in synchronization with all the clients and a successful connection is established.

Initializing WebSocket (for ESP8266 NodeMCU)Ī WebSocket follows a two-way communication protocol using a TCP connection whereby the client and the server can transfer data at the same time.Handling WebSocket on the Server side (ESP8266 NodeMCU).
