Unable to get ESP8266 wifi working

The simplest way is whether the USB connector says 'http://www.espruino.com' on the top, or if it says something like 'CTR1 1234'. Also if it has a little white chip (the fuse) next to that text or not.

Did you attach B9 to CH_PD as well? I'm wondering if the WiFi hasn't had time to power up before it gets the 'reset' sent - please could you try this?

digitalWrite(B9,1);
Serial2.setup(115200, { rx: A3, tx: A2 });
var wifi;
setTimeout(function() {
 wifi = require("ESP8266WiFi_0v25").connect(Seri­al2, function(err){
  if (err) throw err;
  console.log("Connecting to WiFi");
  wifi.connect("MY_LAN", "PASSWORD", function(err){
    if (err) throw err;
    console.log("Connected");
    require("http").get("http://www.pur3.co.­uk/hello.txt", function(res){
      console.log("Response: ", res);
      res.on('data', function(d){ console.log("--->"+d); });
    });
  });
 });
 wifi.at.debug();
}, 1000);
