CC3220SF-LAUNCHXL: aws_demos example program no MQTT message received at AWS IOT Console

Part Number:CC3220SF-LAUNCHXL

Hi,

    I followed the guide below as is but I am not receiving MQTT message from my CC3220SF LP. I am using SDK v1.60. Reviewing the code I should be able to see "Hello World!" at AWS IOT Console. What are the other requirements needed in order for this example program to work?
