ESP8266: CIFSR failed

I've just updated my ESP8266 to 0.25.0.0(Jun 12 2015 20:26:28) (returned by AT+GMR) so I guess I'm on the current version.

I connected the ESP8266 to my Pico's Serial1 port and use a 10uF Cap between the 3.3V and GND on the ESP. When I ran the test script I got a CIPSTART fail, but after reading http://forum.espruino.com/conversations/265995/ I added a timeout before making the call.

Serial1.setup(115200, { rx: B7, tx : B6 });
var wifi = require("ESP8266WiFi").connect(Serial1, function(err) {
  if (err) throw err;
  wifi.at.debug();
  wifi.reset(function(err) {
    if (err) throw err;
    console.log("Connecting to WiFi");
    wifi.connect("myssid","mysecret", function(err) {
      //if (err) throw err;
      console.log("Connected");
      setTimeout(function (){
          wifi.getIP(function(err, ip) {
            console.log(err);
            console.log("ip");
            console.log(ip);
            require("http").get("http://www.pur3.co.uk/hello.txt", function(res) {
              console.log("Response: ",res);
              res.on('data', function(d) {
              console.log("--->"+d);
          });
          });
       });
      },6000);
    });
  });
});

I get the following output:

I can ping the module on IP provided by CIFSR:STAIP but I don't get a response from the GET call.

So I wonder what the error exactly means and how I can fix it. Thanks!

Ahh, ok. I think your issue is you're not using the right module for the ESP8266 firmware - unfortuntely the two are different enough that a different module is needed. Try:

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

Thanks @Gordon! That did the trick and now it works like a charm :)
