[SOLVED] Flashing WeMos D1 Mini Pro (16MB) with Espruino

Just to recap:

steps you did to get a stable Espruino:

• erase flash

• flash files from dir espruino_1v95_esp8266_4mb with flash_size 4mb-c1

Wifi stuff:

Wifi.connect(SSID, {password:SSIDPASS}, function(err){
  if (err === null){
    console.log('Connected to AP');
    Wifi.stopAP();
    Wifi.setConfig({powersave : 'none'});
    Wifi.save();
  } else {
    console.log('connetion error',err);
  }
});

I am interested in output of console.log('connetion error',err);
