I’m trying to integrate a shadow on to an existing project. I have a separate mqtt task running.
In my shadow task. I’m following the same sequence to subscribe to an update topic first.
In the activity, I can see that my device has subscribed to the shadow/update topic but in the console logs I get an ACK time out error with return code : 3
Just checked that I have all the necessary permissions. Could some please advise.
I have my own application running on esp32 which does a mqtt pub/sub acivity.
Now, trying to add shadow as a feature.
As a first step, I’m trying to subscribe to thingname/shadow/update/delta
I use a function below.
As a device, it would subscribe to delta/update
Once the devices changes to the requested it updates the newly updated(reported) state to shadow/update. Is that correct?
