  Hi,
  For some odd reason the code is as follows; Just playing around and bumped into the issue.
  Is anyone else seeing this issue ? I am uploading directly to the ESP8266

  var wifi = require("Wifi");
  
  var server = "192.168.1.25";
  
  var mqtt = require("MQTT").create(server);
  mqtt.on('connected', function() {
    mqtt.subscribe("pcduino");
  });
  
  mqtt.on('publish', function (pub) {
    console.log("topic: "+pub.topic);
    console.log("message: "+pub.message);
  });
  
  
  wifi.stopAP();
  wifi.disconnect(); 
  wifi.scan(function(data){
  
    for(x in data)
    {
      console.log(data[x].ssid);
    }
  
    //wifi.connect("ABC", {password:"xyz"}, function(err){
    //  console.log("connected? err=", err, "info=", wifi.getIP());
    //});
  
    wifi.connect("Zain-E5577-0462", {password:"85887536"}, function(err){
      console.log("connected? err=", err, "info=", wifi.getIP());
      mqtt.connect({
        keep_alive: 60, // keep_alive[seconds]
        port: 1883, // port number
        clean_session: 1883, // port number
        username: "xyz", 
        password: "xyz", 
        protocol_name: "MQTT", // or MQIsdp, etc..
        protocol_level: 0, // protocol_level
      });
    });
  
  });
  

  Error As follows;
