> Now, {{MqttIO}} reader uses {{connection.receive()}} which is a blocking method, waiting for messages. This prevents the reader to return {{false}} when there's no message and so to advance the processing.
> Instead, the reader should use {{connection.receive(timeout, timeunit)}} and return {{false}} in {{advance()}} when message is null.
