    How to Monitor Sensors/Devices via WebSocket

    Advantage of Monitoring via WebSocket
    • Useful to monitor states of sensors/devices in a long period of time without reloading webpage.
    • Data can be sent by server in real-time
    • Reduce network latency and overhead.

    How to Monitor via WebSocket

    This kind of method requires two kind of code:
    • Code run in system loop :
      • Acts as WebSocket server,
      • Reads state from sensors/devices,
      • Send it to WebSoket Client via Websocket.
    • Web App code: this code contains:
      • HTML and CSS code
    ...

    Arduino - TCP IPv6 Chat Server

    What is TCP?

    TCP is abbreviation of Transmission Control Protocol. TCP is one of the popular protocols in Internet. To exchange data between two devices using TCP protocol, one device acts as TCP server, the other acts as TCP client. TCP server listens to wait for TCP connection request from TCP client. TCP Client actively make request for TCP connection to TCP server.

    IPv6 is abbreviation of Internet Protocol version 6, the most recent version of the Internet Protocol...
