  Another question:

  Is it possible to stream using the espruino?

  e.g

  var go = function() {
  
      var req = http.request(options, function(res) {
          console.log(res);
      });
  
      var x = 0;
      setInterval(function() {
          console.log(x);
          data = {"x": x, "y": 1};
          x++;
          json = JSON.stringify(data);
          req.write(json+'\n');
      },100);
  };
  

  Does the espruino support TCP?

  Cool! Got it working, albiet she's a bit shakey. The CC3000 does seem a bit finicky for sure! I can't make too many POSTs, too quickly, and sometimes it just needs to restart after 5-10 successful POSTs. Does the CC3000 hold a connection for as long as it can? Or do you have to run all of your logic inside of the .connect() callback?

  Thanks Gordon! I tried the dev IDE and it works a bit better, but I still can't make a proper POST. The CC3000 times out and restarts everytime, or I get a socket-1 error.

  Here is my code:

  var wlan = require("CC3000");
  var http = require("http");
  
  var data = JSON.stringify([{
      x : 0,
      y : 1,
      type : "scatter",
      mode : "markers"
  }]);
  
  var layout = JSON.stringify({
      fileopt : "extend",
      filename : "Espruino"
  });
  
  
  var payload = {
  un : "demos",
  key : "tj6mr52zgp",
  origin : "plot",
  platform : "rest",
  args : data,
  kwargs : layout,
  version : "0.0.1"
  };
  
  function request() {
    var urlpayload = "un="+payload.un+"&key="+payload.key+"&origin="+payload.origin+"&platform="+payload.platform+"&args="+payload.args+"&kwargs="+payload.kwargs+"&version="+payload.version;
    var options = {
    host: 'plot.ly',
    method: 'POST',
    path: '/clientresp',
    headers: {
            'Content-Type': 'application/x-www-form-urlencoded',
            'Content-Length': urlpayload.length
        }
  };
  
  var req = http.request(options, function(res) {
    console.log('STATUS: ' + res.statusCode);
    console.log('HEADERS: ' + JSON.stringify(res.headers));
    res.on('data', function (chunk) {
      console.log('BODY: ' + chunk);
    });
  });
  
  req.on('error', function(e) {
    console.log('problem with request: ' + e.message);
  });
  
  req.write(urlpayload);
  req.end();
  }
  
  
  wlan.connect( "evilfriends", "password", function (s) {
    if (s=="dhcp") {
      console.log('wifi connected!');
      request();
    }
  });
  

  It seems to be OK until it hits

  req.end()

  wow, sorry about the last comment, i breadboarded my Espruino right away and didnt notice on the bottom there is an SD card slot!

  I'll give that a try for now!

  Cool, thanks for the help. I hope they fix the Mac issue soon. How can I use an SD? It seems to be only supported by some boards, and I have the classic Espruino. Doesn't look like there is an SD card option for that.

  Hey guys, Super stoked on the Espruino, looks like a great platform. That being said, just having some small issues getting started.

  I've installed the Chrome App on OS X, and have a regular Espruino board.

  Now, I've hooked up a DHT11 to a pin (I've tried B2, B3, C0, C1, C2).

  However, using the IDE, I cannot transfer over my sketches. I'm trying simply to use the example provided.

  var dht = require("DHT11").connect(whatever pin im trying);
  dht.read(function (a) {
    console.log("Temp is "+a.temp.toString()+" and RH is "+a.rh.toString());
  });
  

  and nothing happens when i try to send this to the espruino. It just hangs on

  echo(0);
  

  It seems to be an issue with importing modules, as the same happens for a BMP085. Is there something wrong?
