why cannot subscribe "$aws" topic

[nanotoly]

Hello, i'm testing aws iot example code with esp32 and esp-idf

Using example below,
https://github.com/espressif/esp-aws-io ... utual_auth

It works well with normal topic(ex."esp/test/topic").
But It doesn't work with reserved topic(ex. "$aws/certificates/create/json/accepted")

example code show succeed to subscribe log,
But i can't receive any message from reserved topic.



To provisioning i have to subscribe reserved topic below

- $aws/certificates/create/json/accepted
- $aws/certificates/create/json/rejected
- $aws/provisioning-templates/{template name}/provision/json/accepted
- $aws/provisioning-templates/{template name}/provision/json/rejected

But i can't get any message from these topic.

why it doesn't work?



thanks for your help
