Unable to get ESP8266 wifi working

var wifi = require("ESP8266WiFi_0v25").connect(Seri­al2, function(err){ wifi.getVersion(print); });

> null undefined

The code I'm using from espruino.com/ESP8266:

digitalWrite(B9,1);
digitalWrite(A1,0);
digitalWrite(A10,0);
digitalWrite(A10,1);
Serial2.setup(115200, { rx: A3, tx: A2 });
Serial2.on('data', function(d) { USB.write(d); });
USB.on('data', function(d) { Serial2.write(d); });
Serial1.setConsole();

digitalWrite(B9,1);
Serial2.setup(115200, { rx: A3, tx: A2 });

var 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); });
    });
  });
});
