Espruino Wifi v1.1

Ok got it working with:

var WIFI_NAME = "ssid";
var WIFI_OPTIONS = { password : "pw" };
var wifi = require("EspruinoWiFi");
wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) { ...

But the behavior is the same as with separate ESP8266 module: HTTP request is well received and handled by this code, but response does not arrive to browser when making the request:

var wifi = require("EspruinoWiFi");
wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
  if (err) {
    console.log("ERROR connect:"); 
    console.log(err);
    wifi.stopAP();
  } else {
    console.log("Connected");
    wifi.getIP(function (err, ip) {
      if (err) { console.log("ERROR getIP():"); console.log(err); return; }
      console.log("Web server ip: " + ip.ip);
      var http = require("http");
      http.createServer( function(req, res) {
        console.log("Client req: " + req.url);
        if (req.url == "/favicon.ico") {
          res.writeHead(200, {'Content-Type': 'image/x-icon'});
          res.write(favicon);
          console.log("Client served with favicon.ico");
        } else {
          res.writeHead(200, {'Content-Type': 'application/json', 'Connection': 'close'});
          var values = "\nsensors(["+
              "{\"sensor\":\"A0\",\"value\":\""+analogRead(A0)+"\"},"+
              "{\"sensor\":\"A1\",\"value\":\""+analogRead(A1)+"\"},"+
              "{\"sensor\":\"A2\",\"value\":\""+analogRead(A2)+"\"},"+
              "{\"sensor\":\"A3\",\"value\":\""+analogRead(A3)+"\"},"+
              "{\"sensor\":\"A4\",\"value\":\""+analogRead(A4)+"\"},"+
              "{\"sensor\":\"A5\",\"value\":\""+analogRead(A5)+"\"}])";
          res.write(values); 
          console.log("Client served with: " + values);
        }
        res.end(); 
      }).listen(80);
    });
  }
});

Console says "Client served with: ...", but that response never arrives to chrome browser that I am testing with.

What is wrong with the code above or the setup (EspruinoWifi plugged into laptop USB)?
