Espruino WiFi & MDBT42Q

OK, now it works!
Gordon, allObjects thank you very much!

For whoever needed, here is the code useful for testing ...

// Espruino WiFi
// Web IDE > reset(true);

Serial1.setup(9600, {rx: B7, tx: B6});
LED2.write(0);
var WIFI_NAME = "NAME";
var WIFI_OPTIONS = {password: "PASSWORD"};
var wifi;

function getString() {
  LED2.write(0);
  require("http").get("http://www.pur3.co.­uk/hello.txt", function(res) {
    var doc = "";
    res.on('data', function(d) { 
      doc += d;
    }); // data
    res.on('close', function(d) {
      doc = doc.substring(0, 5);
      Serial1.println(doc);
      LED2.write(1);
      setTimeout(function (){LED2.write(0);}, 15000);
    }); // close
  }); // get
};

function onInit() {
  USB.setConsole(1);
  clearInterval();
  wifi = require("Wifi");
  wifi.connect(WIFI_NAME, WIFI_OPTIONS, function(err) {
      if (err) throw err;
      setInterval(getString, 30000);
      getString();
  });
};

// Web IDE > save();
// Web IDE > disconnect
// Connected to battery

// MDBT42Q
// Web IDE > reset(true);

global.LED2 = D2;
global.LED2.write(0);
var count = 0;

function updateBT(wifi) {
  count = count + 1;
  var data = E.toString(wifi + count);
  global.LED2.write(1);
  setTimeout(function (){global.LED2.write(0);}, 6000);
  NRF.setAdvertising({}, {
    name: "TEST",
    manufacturer: 0x590,
    manufacturerData: data,
    showName: true
  });
};

function onInit() {
  var cmd = "";
  Bluetooth.setConsole(1);
  Serial1.setup(9600, {rx: D8, tx: D6});
  Serial1.on('data', function (wifi) {
    cmd += wifi;
    var idx = cmd.indexOf("\r");
    while (idx >= 0) {
      var line = cmd.substr(0, idx);
      line = line.substring(0, 5);
      line = line.toLowerCase();
      cmd = cmd.substr(idx + 1);
      clearInterval();
      setInterval(updateBT, 15000, line);
      updateBT(line);
      idx = cmd.indexOf("\r");
    };
  });
};
