Hello,

Doing the Example 1 of the AN4683 (TLS Example 1, mutual auth), all commands work without problem (keys and certificate generation), same for imports in Wifi module (send back ''OK'') But the last command : AT+S.SOCKON=ipaddress,443,s returns ''ERROR: Unable to load CA certificate'' (of course ipaddress is the ip address of my TLS server) I have several questions : - Is the CA certificate checked during import in the module ? According to my test, the certificate is not checked during import (could you confirm ?) - Is the example given in the doc works for you ? - Any clue ? Thanks a lot Zirco

Thank you Gerardo, I checked the two threads.

In fact, the loading was incorrect due to way I did it. I use gtkterm on LInux and did the import by a cut/past of the PEM text. In fact, it's mandatory to use the menu ''send raw file'' to import the certificate. Regards Zirco
