With the funny sleep message and failing to restart It feels like there is something still not quite correct about the config I'm using. Is there doc somewhere on what configuration should be set when using an ESP32 C3? Or could it be the Adafruit QT Py module and if I tried some other C3 module it...

Yes thats right - https://github.com/espressif/esp-idf/bl ... rld_main.c

Anyway I have done that now and get further but still not perfect. With ESP-IDF the helloworld sam...
