We looked into the issue and we found no issues with the connection part.
Our config.xml was this

<?xml version='1.0' encoding='utf-8'?>
<widget id="com.phonegap.helloworld" version="1.0.0" xmlns="http://www.w3.org/ns/widgets" xmlns:gap="http://phonegap.com/ns/1.0">
    <name>Hello World</name>

</widget>

And our connection configuration was this

cordova.plugins.CordovaMqTTPlugin.connect({
    url:"tcp://test.mosquitto.org", //a public broker used for testing purposes only. Try using a self hosted broker for production.
    port:1883, 
    clientId:"arcoirislabs",
    connectionTimeout:3000,
    willTopicConfig:{
        qos:0,
        retain:true,
        topic:"<will topic>",
        payload:"<will topic message>"
    },
    keepAlive:60,
    success:function(s){
        console.log("connect success");
    },
    error:function(e){
        console.log("connect error");
    },
    onConnectionLost:function (){
        console.log("disconnect");
    }
})

And it worked perfectly fine. If you need we can provide you the APK.

@ionciubotaru
We tried to recreate the issue and it seems that either you used credentials for a public broker or the client ID's length exceed the 24 chars length limit.
If you still got any issues, do let us know.
We will be glad to help you.
