ChronoFly WebSocket

WebSocket support enables other applications to control ChronoFly and obtain real time passing data.

Do not expose your timing network for unauthorized access! There is no authentication mechanism in this WebSocket implementation.

Usage example

JavaScript:

var j2ws = new WebSocket("ws://localhost:2235");

j2ws.onmessage = function(e) {
  var event = e.data.split(": ")[0];
  var value = e.data.split(": ")[1];

  switch(event) {
    case "pas":
      console.log("Passing with transponder: " + value);
      break;
    case "ion":
      console.log("Digital input " + value + " ON");
      break;
  }
}

var startTiming = function() {
  j2ws.send("tim: 1");
}
