What about new version of module ESP8266WiFi

Hi - many thanks for your time and good result!
I have been on holiday now but luckily I have Pico+ESP8266 on the breadboard with :-).
I have made some tests "in the battle field" and all have been OK. I have also modified one of your programms and it has been running more than 24 hours without any failure... More tinkering at home again...

var WLAN_NAME   = "MySSID";
var WLAN_KEY    = "MyPSW";
var WEATHER_URL = "http://open.live.bbc.co.uk/weather/feeds/en/2643743/observations.rss"; 

var wifi;

// This gets the weather out of the XML and writes it to the LCD ... console.log ...
function parseWeather(xml, date) {
  // No XML parser, so we have to be nasty
  var item = xml.indexOf("<item>");
  var descStart = xml.indexOf("<description>", item);
  var descEnd= xml.indexOf("</description>", descStart);
  var desc = xml.substring(descStart+13,descEnd);
  var titleStart=xml.indexOf("<title>");
  var titleEnd=xml.indexOf("</title>");
  var title=xml.slice(titleStart+7,titleEnd);
  var pubDateStart=xml.indexOf("<pubDate>");
  var pubDateEnd=xml.indexOf("</pubDate>");
  var pubDate=xml.slice(pubDateStart+9,pubDateEnd);
  // replace the degrees symbol with a quote - built in font only does first 128 chars
  desc = desc.replace("°","'").replace("°","'").replace("mb,","mb");
  // make sure things fit on the tiny screen!
  desc = desc.replace("Wind Direction","Wind").replace("Temperature:","Temp:");
  console.log("--- "+title);
  // draw one item per line
  var weather = desc.split(", ");
    weather.forEach(function(s) {console.log(s);});
  // Finally print the time from the HTTP request (so we know it's up to date!)
  // var d = new Date(date);
  // var timeStr = d.getHours()+":"+("0"+d.getMinutes()).substr(-2);
  console.log("PubDate: "+pubDate);
  console.log("---");
}

// Actually get weather off the net and display it
function getWeather() {
  // do an HTTP request
  require("http").get(WEATHER_URL, function(res) {
    // console.log("Response: ",res);
    // read the whole response into a variable
    // note: this works here but isn't a great idea - big responses can
    // easily use up all the available memory
    var xml = "";
    res.on('data', function(d) { xml += d; });
    // when the connection closes, parse the weather and write to the LCD
    res.on('close', function(d) { parseWeather(xml, res.headers.Date); });
  });
}

// When we start up...
function onInit() {
  // if we save()d to flash after we'd already run onInit() we need to clear existing intervals
  clearInterval();
  // Set up the ESP8266
  Serial2.setup(115200, { rx: A3, tx : A2 });
  console.log("Init ESP8266...");
  wifi = require("ESP8266WiFi_0v25").connect(Serial2, function(err) {
    if (err) throw err;
    wifi.reset(function(err) {
      if (err) throw err;
      console.log("Connecting to WiFi");
      wifi.connect(WLAN_NAME, WLAN_KEY, function(err) {
        if (err) throw err;
        console.log("Connected");
        // Now start getting weather...
        setInterval(getWeather, 60000); // every 60s
        getWeather(); // do the first one right away
      });
    });
  });
  console.log("Please wait...");
}

onInit();
