    For mosquitto on windows 10 I had to remove the -v flag to make it work. Thanks for the straight to the point video, very useful :)

    hey is there a way to publish a function's result instead of hardcoding it ?

    nice and simple, do you have a simple combination of both in one program because loop_forever is blocking.

    Hi, do have you already done a pub sub connection with UDP in open62541? If yes, could you share this with us? Regards

    My Subscriber one doesn't get the message, it just prints the CTRL+C message and stays there, even when I send a message from my PLC, - (so not only does it not get the message from the publisher code I just copied from you)

      I use the mosquitto broker here (mosquitto -v). Everything (Client and Broker) are running on my localhost.

      @@ashwaryaarora6 Here you find the mosquitto broker for Linux. Paho-mqtt can be installed over pip. Then you have everything you need. Even on Windows having the broker and the clients on the same host shouldn't be a problem.-

    import paho.mqtt.client as paho
    import sys
    def onMessage(client, userdata, msg):
    print(msg.topic + ": " + msg.payload.decode())

    client = paho.Client()
    client.on_message = onMessage
    if client.connect("your-host-name", 1883, 60) != 0:
    print("Could not connect to MQTT Broker!")
    sys.exit(-1)
    client.subscribe("Capstone")
    client.publish("Capstone", "Happy Birthday")
    try:
    print("Press CTRL+C to exit...")
    client.loop_forever()
    except:
    print("Disconnecting from broker...")
    client.disconnect()
    thanks it worked!
