Hi, with the custom firmware everything works perfectly!

After flashing, following these directions: https://github.com/pvvx/ATC_MiThermometer

@Vlad's code fetches values without problems:

var temp = null;
    var humidity = null;
    var battery = null;
    function getSensorData() {
        NRF.findDevices(function(devices) {
                if (devices[0] && devices[0].serviceData.fe95) {
                    var data = devices[0].serviceData.fe95;
                    // console.log(data);
                    var flag = data[11];
                    // console.log(flag);
                    
                    switch (flag) {
                        case 4: {
                            // temp
                            temp = (data[14] | data[15] << 8) / 10;
                            break;
                        }
                        case 6: {
                            // humidity
                            humidity = (data[14] | data[15] << 8) / 10;
                            break;
                        }
                        case 10: {
                            // battery
                            battery = devices[0].serviceData.fe95[14];
                            break;
                        }
                        case 13: {
                            // temp and humidity
                            temp = (data[14] | data[15] << 8) / 10;
                            humidity = (data[16] | data[17] << 8) / 10;
                            break;
                        }
                        default : {
                            print("Unknown flag: " + flag);
                        }
                    }
                }
                for (var i = 0; i < devices.length; i++) {
                    devices[i] = null;
                }
                devices = null;
            }, {
                filters: [
                    {serviceData:{"fe95":{}}}
                ],
                timeout: 2000
            }
        );
    }
    setInterval(function () {
        print("Temp: " + temp + " humidity: " + humidity + " battery: " + battery);
        getSensorData();
    }, 5000);

THANK YOU ALL!

Hi @fanoush, you are right, in the next few days I will hack one :-)

See you soon!

Hi @fanoush, thanks for the link, I initially saw something about: https://github.com/atc1441/ATC_MiThermometer

Then I saw that through Python, without any hacks, you can get the values easily.

Maybe later, I sacrifice one in the name of science :-)

Hi @Gordon, I uploaded this code to Pixl.js (2v08)

var deviceInfo = {};

function parseDevice(device) {
  var d = new DataView(device.serviceData["fe95"]);
  var frame = d.getUint16(0, true);
  var offset = 5;

  console.log("FRAME: " + frame);

  if (frame&16) offset+=6; // mac address
  if (frame&32) offset+=1; // capabilitities
  if (frame&64) { // event
    var l = d.getUint8(offset+2);
    var code = d.getUint16(offset,true);
    if (!deviceInfo[device.id]) deviceInfo[device.id]={id:device.id};
    event = deviceInfo[device.id];
    switch (code) {
      case 0x1004: event.temperature = d.getInt16(offset+3,true)/10; break;
      case 0x1006: event.humidity = d.getInt16(offset+3)/10; break;
      case 0x100D:
        event.temperature = d.getInt16(offset+3,true)/10;
        event.humidity = d.getInt16(offset+5)/10; break;
      case 0x1008: event.moisture = d.getUint8(offset+3); break;
      case 0x1009: event.fertility = d.getUint16(offset+3,true)/10; break;
      // case 0x1007: break; // 3 bytes? got 84,0,0 or 68,0,0
      default: event.code = code;
        event.raw = new Uint8Array(d.buffer, offset+3, l);
        break;
    }
    print(event);
  }

};

setInterval(function () {
    NRF.setScan(parseDevice, { filters: [{serviceData:{"fe95":{}}}], timeout: 2000 });
}, 5000);

It always prints FRAME, and when the temperature or humidity changes it prints the event:

FRAME: 22616
{
  "id": "a5:c2:83:xx:xx:xx public",
  "code": 50578,
  "raw": new Uint8Array([208, 117, 0, 0, 58, 221, 132, 170, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0])
 }

FRAME: 22616
{
  "id": "a5:c2:83:xx:xx:xx public",
  "code": 15670,
  "raw": new Uint8Array([121, 182, 117, 0, 0, 185, 254, 166, 227, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0])
 }

I have no idea how to extract the temperature and humidity :-)

Can I get some useful info from this Python code (0x80, 0x7F)?

https://github.com/adafruit/Adafruit_CircuitPython_BLE_LYWSD03MMC/blob/main/adafruit_ble_lywsd03mmc.py

THANK YOU

Hi @Gordon, thanks for the reply.

As soon as I have time, I try the code on my Pixl.js and tell you!

See you soon :-)

Hi @Gordon, hi @Vlad

I have a Xiaomi LYWSD03MMC Thermometer / Hygrometer and with this CircuitPython library I can fetch its values:

https://github.com/adafruit/Adafruit_CircuitPython_BLE_LYWSD03MMC/blob/main/adafruit_ble_lywsd03mmc.py

Now I'd like to make everything work on Espruino thanks to your code.

I changed filters: [{serviceData: {"fe95": {}}}] the device is found (although its serviceData should be "ebe0ccb0") but all values remain null.

How do you think it could be solved?

THANK YOU

OK, thanks anyway ... if I solve, I'll write you how I did!

:-)

Hi Gordon!

Programming via Bluetooth is OK, but via USB it is only powered, it is not recognized and the "MICROBIT" drive is not mounted ... I don't know how to update to 2.06

I've tried both on Mac and Windows (with related drivers) and with different USB cables.

THANK YOU SO MUCH

Hello. In this situation, exist a way to update / restore to factory defaults via drag n drop, Espruino Web IDE, WebUSB, BLE DFU App, Serial Port Terminal?

There is a key combination or "jumper-bridge" between pins to activate the bootloader?

:-(

THANK YOU

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!

Gordon, allObjects thank you very much!

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

Thanks allObjects, i can't wait to try it!

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"};

  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();
  });
};

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{};
};

   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);

GREAT, IT WORKS!

THANK YOU SO MUCH!

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
