The SDK is :
The IDE is :
MCUXpresso IDE v10.3.1 [Build 2233] [2019-02-20]
Once it fails , it will never be able to publish again. The only way to fix it is to terminate the debug session and start over again from beginning..
My AWS iot thing is OK.. I can see the shadow update message from Mqtt Fx Client. As you can see from the above log , the errors happened after many successful publishes. I could duplicate the error if I re-run the program. The time to get the error message is random. Sometimes it runs more than one hours to show the error , sometimes errors come out in 10 minutes.. Anyone see something like it ??
Thanks
Rick
