So I have my new ESP8266 and it is up and running. Couple problems. I'm still having problems with the "AT wasn't found". Happens way too often and I have a great internet connection.

The second part is creating an access point. This works:


Serial2.setup(115200, { rx: A3, tx : A2 });
var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
  if (err) throw err;
  wifi.reset(function(err) {
    if (err) throw err;
    console.log("Connecting to WiFi");
    wifi.createAP("Test", "guest", 1, "wep", function(err) {
      console.log("Connected");
      require("http").createServer(function (req, res) {
        res.writeHead(200, {'Content-Type': 'text/plain'});
        res.write('Hello World');
        res.end();
      }).listen(80);
    });
  });
});

But this is having issues:


function onPageRequest(req, res) {
  var a = url.parse(req.url, true);
  res.writeHead(200, {'Content-Type': 'text/html'});
  res.write('<html><body>');
  res.write('<p>Pin is '+(BTN.read()?'on':'off')+'</p>');
  res.write('<a href="?led=1">on</a><br/><a href="?led=0">off</a>');
  res.end('</body></html>');
  if ("led" in a.query) digitalWrite(LED1, a.query["led"]);
}

Serial2.setup(115200, { rx: A3, tx : A2 });
var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
  if (err) throw err;
  wifi.reset(function(err) {
    if (err) throw err;
    console.log("Connecting to WiFi");
    wifi.createAP("Test", "guest", 1, "wep", function(err) {
      console.log("Connected");
      require("http").createServer(onPageRequest).listen(80);
    });
  });
});

says this:


Uncaught Error: Field or method "led" does not already exist, and can't create it on null
 at line 8 col 57
  if ("led" in a.query) digitalWrite(LED1, a.query["led"]);
