I'm running the latest free rtos publish subscribe example from the aws iot plugin and can not get it to work. I get the following output:

Starting the AWS IoT example application

CC32XX has connected to AP and acquired an IP address.

David,

Can you validate that your AP you are connecting to has internet access? Specifically that its not behind a firewall that is blocking traffic to certain urls?

Hi Vincent,

Thank you for your help, How would you like me validate this? Are you talking about the firewall on my router? Doesn't the fact that the uart output shows a connection to the sntp server show thatt this is the case. Also, when I run amazons example called aws demo it works okay. I've done some digging and found out that the error returned is the NETWORK_SSL_WRITE_ERROR in the iot_tls_write function when send() returns -1 in network_sl.c. Any help would be greatly appreaciated as I have spends days trying to get this example working. Could this be a certificate issue? If so attached is my certs.h file.4278.certs.h

Hi David,

I don't think the root CA certificate you are using is correct. Please see my attached certs.h and try that.

Hi David,

If you run your AWS example with the debugger and step through aws_iot_mqtt_connect(), where does the error -7 originate from?
Also, have you double-checked your settings in aws_iot_config.h? You need to make sure AWS_IOT_MQTT_HOST and AWS_IOT_MY_THING_NAME match what you have on the cloud.

Michael
