Hi Neil.
Long time no see. I am trying to do something similar to what you have done above - I have my Azure hub set up and can talk to it via my Beaglebone ok (trying to open the door of my Chicken Coop). What I'm not getting is where the Primary Key/Connection String gets inserted using the MQTT (Cowen71). I seem to connect to the hub ok, just not the device. Can you offer any assistance?
Thanks, Rob (FIF1)
