Arduino board: ESP32
-
Arduino IDE version (found in Arduino -> About Arduino menu): 1.8.13
Although I see ESP8266 have a fingerprint in order to connect with TLS credentials, i have search all code and libraries included, but i cannot find CA certificate for ESP32 secured connection to AdafruitIO.
WiFisecure example of ESP32, has CA certificate hardcoded, but in adafruit's example (although it's working fine), there is nowhere a fingerprint or CA cert. So, how the connection is secured?
