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 :)

[@JagathSelvans]

you saved me

[@noweare1]

Yes, very simple, python is such a great language.

[@Aviel777Gergel]

first example that perfectly worked for me

[@benjaminwe4]

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

[@intanaidazulaiqabintiabdul5204]

3:55-4:05 : what did you click? I didnt get it

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

[@onlinefaxmachine2821]

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)

[@SA-oj3bo]

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

[@SA-oj3bo]

@@johannes4gnu_linux96 Yes loop_start followed with a while works fine. Great!

who is the broker here?

[@johannes4gnu_linux96]

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

[@ashwaryaarora6]

@@johannes4gnu_linux96 i want to do the same thing but I’m confused Like can my windows machine be both publisher n subscriber or do I use kali for one Here have u downloaded mosquito ?

[@johannes4gnu_linux96]

@@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.-

@@johannes4gnu_linux96 yes I got it thanks to your video i will refer it in my report 😊

With threading: client = mqtt.Client() AttributeError: 'function' object has no attribute 'Client'

I want to find you and kiss you ! After hours of research, you where the one giving me the right solution ^^ !

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!
