I looked for MqttMessage on Google and it seems like getPayload() gives you
a byte array.
So if you know that it could be a String that says "connected", you just
need to compare the strings.
String message = new String(message.getPayload());
if(message.equals("connected")) {
// Do stuff
}
You could also check equalsIgnoreCase if you don't know the capitalization.
If that "connected" is not a string but it's on some kind of object, I'm
guessing you'll need to use serialization. But I'm just using simple Java
knowledge, I don't know your project.
