    Yes, those are because of the old firmware. If you’ve got it working, it may not be worth updating, but it should eliminate those work-around.

    If you want to use custom SSL certificates, upgrade. The only way to push custom certificates with the old firmware (or with an ESP8266) is to use a python script to write the memory blocks with the new certificate data. And getting that working is much harder than upgrading the firmware. AWS IoT core requires custom certificates.
