#70098 When executing "AT + CIPSTART", the response is ERROR.
(Attempting to access by SSL)
As a result of analysis using Wireshark, "handshake failure" was returned to "ServerHello".
In order to clarify why the error occurs, I want to check the SDK and analyze processing by AT Command.
But I do not know which file corresponds.
How should I analyze it?

SDK is "NON - OS SDK V2.1.0".
