# How it works

This demo uses 2 WebScokets. Status parameters are streamed by the server in JSON format every 2 seconds. A `websocket_task` is created each time a specific URI is requested.

ADC values are being continuously polled by the client (i.e. your browser). Each time a WebSocket frame is received on the server side, `websocket_cb` function is being called.
