Re: How to change task watchdog timeout?

I believe the esp-idf components are compiled into libraries for Arduino(see https://github.com/espressif/arduino-esp32/tree/master/tools/sdk/lib ). There is a option to change the task watchdog timeout in esp-idf under sdkconfig, but since for Arduino it is precompiled you might have to switch to u...

Re: ESP32 Sparkfun Reset with External Battery 3.7v

Why do you call openocd in msys2? http://esp-idf.readthedocs.io/en/latest ... ndows.html There you can find the windows binary for openocd.

Re: openssl certs in ESP32

In this example there is no certificate to be verified. You can print the received certificates by enabling debug for openssl/mbedtls ( this will print ALOT of information )
