问题 Azure has implemented MQTT protocol in its IoTHub so I'm trying to use mosquitto to send messages from my pc. I'm creating azure devices using Device Explorer. In the beginning I generated SAS token from there, but it hasn't the "&skn=" part, so I tried to generate a new SAS using compatible event hub from visual studio.

问题 I am using mosquitto mqtt client. For example, you have users that publish and subscribe to topics. The topic actually correlates to a REsT endpoint. Scenario 1 (typical pub/sub usage) UserA subscribes to topic /device/123/meta UserB publishes some data to topic /device/123/meta by definition, this publish is broadcasted out to the subscribers we have a script subscribed to /devices/# which knows how to save the payload for the topic /device/123/meta when it receives publish'ed data.
