If you are asking a question, please follow this template:

  1. My goal is: how to renew or create new aws cert on iot device running mongoose os
  2. My actions are: used “mos aws-iot-setup” to put new certs on device
  3. The result I see is: seems some certs may be expiring
  4. My expectation & question is:
    a.) How long cert from “mos aws-iot-setup” lasts? and
    b.) How to renew or create new aws cert on iot device running mongoose os?

You can get that info by examining the certificate itself on a computer.
In linux mos uses openssl to generate the key and then asks AWS to sign the certificate. You can also check the expiration date within AWS IoT console.
The ones I generated some months ago will expire on 2049…
AFAIK there is no renew option.
