CC3220 - AWS CA certificates don't work

Daniel Stepan

Hello,

I've been testing examples 'shadow_sample' and 'subscribe_publish_sample' with AWS. Everything works fine with the old root CA certificate VeriSign. However, if I use any of the new Amazon root CA certificates ( https://docs.aws.amazon.com/iot/latest/developerguide/managing-device-certs.html ) it does not work. It is failing to connect to AWS with error -7.

My question is: why does it not support the new root certificates, which are recommended to be used instead of the old VeriSign one?

Thank you for clarification.

Hi,

You can use the new ATS endpoint. You'll simply need to load the correct root CA certificate to verify the ATS chain, which is the Starfield Class 2 Certificate Authority certificate. See my post here for details:

Let me know if you need more clarification, or if you have further questions.

Regards,
Michael

With Starfield Class 2 Certificate Authority it works fine.
