Re: HTTPS request example failed (mbedtls_ssl_handshake returned -0x7680)

Hi! Thanks for response. I did not change anything after generating example (only Wifi creds.). I changed that line in mbedtls's CMakeLists.txt as you advised and it results in this error: -- Found Git: /usr/bin/git (found version "2.26.2") -- The C compiler identification is GNU 8.2.0 -- The CXX co...

First case: One leg of button to GND and one connected directly to ESP32 Software pull_up void add_button(uint8_t gpio_pin) { gpio_config_t io_conf; io_conf.intr_type = GPIO_...
