ESP32-C3: problem with SSL certificates

[Andrea]

Hi Team,

I have a problem on the ESP32-C3 with FW factory_MINI-1.bin in rev. AT_Bin_V2.3.0.0 that I have not been able to solve for about ten days.

Together with the sw developer, we have already configured a PWA web app, it works correctly after the user approval of the unsecure connection. However, we want this authorization to be more robust and less volatile, so we opted to enable the certificates, but with the factory certificates we are unable to connect.

These are the commands with which I configure the module:
AT + CWMODE = 3
AT + CIPMUX = 1
AT + CIPSERVER = 1,443, "SSL", 1

What should I do to activate the certificates?
If I have to generate them from scratch, how can I convert the .crt and .key files to bin?

Thank you
