Python MQTT connection to Azure Iot Hub

Question

I want to connect to Azure Iot Hub, with Python MQTT.

An username and SAS token is required by Iot Hub. This is my code:

import paho.mqtt.client as m         


        

Answer 1

Here is how to use paho (mosquitto) to connect to the Azure IoT Hub over standard MQTT:

from paho.mqtt import client as mqtt


def on_connect(client, userdata, flags, rc):
    print "Connected with result code: %s" % rc
    client.subscribe("devices//messages/devicebound/#")


def on_disconnect(client, userdata, rc):
    print "Disconnected with result code: %s" % rc


def on_message(client, userdata, msg):
    print " - ".join((msg.topic, str(msg.payload)))
    # Do this only if you want to send a reply message every time you receive one
    client.publish("devices//messages/events", "REPLY", qos=1)


def on_publish(client, userdata, mid):
    print "Sent message"


client = mqtt.Client(cleint_id=, protocol=mqtt.MQTTv311)
client.on_connect = on_connect
client.on_disconnect = on_disconnect
client.on_message = on_message
client.on_publish = on_publish
client.username_pw_set(username=".azure-devices.net/",
                       password="")
client.tls_insecure_set(True) # You can also set the proper certificate using client.tls_set()
client.connect(".azure-devices.net", port=8883)
client.loop_forever()
