Using MQTT in the IDE App

Hello everyone,

Has anyone sucessfuly used the MQTT blocks in the IDE App's Visual Coding Environment?

I set up a local MQTT broker and configured it in the tiger editor. However, when I try to subscribe or publish a message, I get an error "1234 NameError("name 'url' is not defined",)" threw by the get_connected_client function of the mqtt class:

def get_connected_client(self):
        if not self.connect_started:
            self.connect_started = True
            self.client.connect(url, port)
            threading.Thread(target=self.client.loop_forever).start()
        return self.client

It seems that the mqtt object does not recognize the url variable, which might be caused by the fact that this value is not stored in the __init__ function:

def __init__(self, url, port, encrypted):
        self.client = paho_mqtt_client.Client('tiger')
        self.client.on_message = lambda client, userdata, message: events.emit(
            'mqtttopic' + message.topic, 'message', message.payload.decode("utf-8"))
        if encrypted:
            self.client.tls_set()
        proxy = os.environ.get('HTTP_PROXY') or os.environ.get('http_proxy')
        if proxy:
            proxy = re.search(r"^\w*:\/\/(.*):(\d*)", proxy)
            self.client.proxy_set(proxy_type=3, proxy_addr=proxy.group(1), proxy_port=int(proxy.group(2)))

I tried to adjust the code in the textual coding envirnoment but it did not change the code stored in the blocks. Has anyone encountered (and hopefully solved) a similar issue?
