We are using AZ IoT SDK 1.3.8 with ESP32 platform.
As I noticed that as long as we use AZ IoT SDK, we do not need to update the certificate. however, the SDK includes cert.c which includes multiple root CAs.
So, my questions are :
1. do we still need to update the certificate as long as we use only IoT hub and DPS?
2. If we use other service which requires https connection, do we need to update it?
