    Hi fanoush, I haven't changed anything, I switched from MicroPython to espruino_2v04_microbit.hex via drag n drop: https://www.espruino.com/binaries/esprui­no_2v04_microbit.hex

    :-(

    THANK YOU

    Hi everyone, I would like to upgrade my Micro:bit from version 2.04 to 2.06, but I noticed that both with different USB cables on both Mac and Windows (with related drivers) flash memory never loads ... and RESET button doesn't work either!

    The example code loaded via BLE works fine, but for saving to flash permanently I am forced to reset(true); save();

    Saving via IDE to "Flash" gives me error: Uncaught Error: Module Storage not found ... require("Storage").write(".bootcde","var­ on = false;\nsetIn

    Do you know how to make flash memory reappear on desktop?

    Here are some more info, THANK YOU for your collaboration!

    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");
    };
  });
};

    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?

    // 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() {
  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
};

function onInit() {
  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;

function updateBT(wifi) {
   var data = E.toString(wifi);
   data = data.toLowerCase();  // hello
   if(data == "hello"){
      global.LED2.write(1);
      NRF.setAdvertising({}, {
         name: "TEST",
         manufacturer: 0x590,
         manufacturerData: data,
         showName: true
      });
   }
   else{};
};

function onInit() {
   var cmd = "";
   Serial1.setup(9600, {rx: D8, tx: D6});
   Serial1.on('data', function (wifi) {
      global.LED2.write(0);
      cmd += wifi;
      var idx = cmd.indexOf("\r");
      while (idx >= 0) {
         var line = cmd.substr(0, idx);
         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

// Espruino WiFi > LED green (Hello)
// MDBT42Q > ???
