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

  Hi Gordon!
  As soon as I have a moment, I try it and I tell you ...

  Thank you so much!

  Hi everyone,
  I would like to create a bluetooth notification system,
  by serial connection of an Espruino WiFi (connected to the internet) to an MDBT42Q.

  When I unplug them from the Web IDE console and power them on batteries (charged)
  MDBT42Q gives me no feedback ...

  I think there is a problem with serial communication,
  I have tested them separately and have never given me hardware / software problems

  Could you help me understand where I'm wrong?

  Serial1.setup(9600, {rx: B7, tx: B6});

    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); // Hello
        Serial1.println(doc);
        LED2.write(1);
      }); // close
    }); // get

  Hi everyone,
  I would like to use this Joystick: https://www.adafruit.com/product/512
  with the Espruino WiFi (2v02), it currently works on Feather M4 Express (CircuitPython):

  import ...
  
  stickY = analogio.AnalogIn(board.A0) # analog
  stickX = analogio.AnalogIn(board.A1) # analog
  stickSelect = DigitalInOut(board.A2) # digital
  stickSelect.direction = Direction.INPUT
  stickSelect.pull = Pull.UP
  
  while True:
  ... yValue = stickY.value
  ... xValue = stickX.value
  ... selectValue = stickSelect.value
  ... if yValue > 90 and yValue < 32000: print("Y DOWN")
  ... elif yValue > 40000 and yValue < 65500: print("Y UP")
  ... elif xValue > 90 and xValue < 32000: print("X LEFT")
  ... elif xValue > 40000 and xValue < 65500: print("X RIGHT")
  ... elif selectValue == False: print("PRESS")
  ... else: pass
  

  In JavaScript I'm doing tests, Y and X both are recognized at '50 %' (yes UP and LEFT, no DOWN and RIGHT) ...

  var BTN = {Y: A0, X: A1, SELECT: B10};
  pinMode(BTN.Y, "input_pulldown");
  pinMode(BTN.X, "input_pulldown");
  pinMode(BTN.SELECT, "input_pulldown"); // (auto, input_pulldown and input_pullup) => NOT WORK
  
  while(true){
    if (BTN.Y.read()){console.log("Y");}
    else if (BTN.X.read()){console.log("X");}
    else if (BTN.SELECT.read()){console.log("SELECT"­);}
    else {};
  };
  

  What do you think I can solve?

  THANK YOU
