Recently I have started exploring IBM Bluemix and IoT. What I used to do was that, earlier I replicated Parking Lot App as shown in the document on link. that time the app worked fine. I tried modifying the features and now when i try to replicate the same app again I see the code structure is changed. the "mqtt" folder which was there previously is missing/omitted from the code. For some reason I am unable to find the callbacks which were there in files under "mqtt" folder. I checked the above mentioned doc if its modified, but it is still the old doc which is there since March.
can someone guide me on this?
