SSL passthrough transmission V1.7

Postby disegni » Wed Feb 13, 2019 7:02 pm

Hello, I have a question related to SSL passthrough transmission with the new AT command firmware V. 1.7. It stems from reading the manual where I see an apparent contradiction in what is stated in these two paragraphs:

ESP8266 AT Instruction Set (Version 3.0)

5.2.3. AT+CIPSTART—Establishes TCP Connection, UDP Transmission or SSL Connection (P. 43 - Notes)

SSL connection does not support UART-Wi-Fi passthrough mode (transparent transmission).

5.2.5. AT+CIPSSLCCONF - Sets Configuration of ESP SSL Client (P. 44 - notes)

"This configuration will be saved in the flash user parameter area. If an UART-SSL passthrough transmission is set by command AT+SAVETRANSLINK, the SSL connection will follow the previous AT+CIPSSLCCONF setting."

So is SSL passthrough transmission supported or not?

Thank you for your kind reply.

Thanks for reporting, we have revised the doc.
ESP8266 AT does not support UART-SSL passthrough mode, but the ESP32 does.
