I am trying to work with AWS subscribe and publish example code. I have created the things and certificates in AWS IOT. After successfully loading the binary file to the device it shows the following date in the terminal.
"
Starting the AWS IoT example application
startSNTP: Current time: Thu Sep 16 05:07:03 2021
CC32XX has connected to AP and acquired an IP address.
IP Address: 192.168.1.45
AWS IoT SDK Version 3.0.1-
Connecting...
ERROR: runAWSClient L#108
Error(-4) connecting to xxxxxx-ats.iot.us-east-1.amazonaws.com:8883
"
I found similar kinds of issues in the forum and according to the forum tested the device with many Root certificates and the error code sometimes changed to -12.
When I checked with the latest SDK and found that its SSL error -688 still has no connection with AWS.
