  Thanks for your message. Unfortunately my phone hasn't the right SW 😀... I'll have a look at it when I am at home.

• ESP8266 Adaptor shim

  Hi, I am on holiday... bad conditions for communication... I have some inspirative ideas for shim but as I see you are finished... great work!!! When I am back I will send you some ideas for discussion... maybe next generation of shim :). Please, can you publish electric diagramm to?

  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();
