Try using websockets

Webserver method

var n = 4, chk=5*1024;
var tdata=new Uint8Array(chk);
var i;
for(i=0;i<1024;i++){
  tdata[i]=0x30;
  tdata[i+1024]=0x31;
  tdata[i+1024*2]=0x32;
  tdata[i+1024*3]=0x33;
  tdata[i+1024*4]=0x34;
}//next i

var page = '<html><body><script>var ws;setTimeout(function(){';
page += 'ws = new WebSocket("ws://" + location.host + "/my_websocket", "protocolOne");';
page += 'ws.onmessage = function (event) { document.write("MSG:"+event.data); };';
page += 'setTimeout(function() { ws.send("Hello to Espruino!"); }, 1000);';
page += '},1000);</script></body></html>';

function onPageRequest(req, res) {
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.end(page);
}
//////

if(Hardware===1){

if(Hardware===0)Serial.setup(115200, { rx: C11, tx : C10 }); 
//espruino board

console.log("Start connection process");
var wifi = require("ESP8266WiFi_0v25").connect(Serial, function(err) {

  wifi.connect(hotspots[hotspot].SSID,hotspots[hotspot].key, function(err) {console.log(err);
   if (err){Startagain=1;return;

    wifi.getIP(function(l,ip){

     console.log("IP= ",ip,"\n\r"+l);
     console.log("Wi-Fi Connected");
