GPIO12 is a strapping pin on the original ESP32: high at reset, it powers the flash at 1.8 V. A CC1101 can hold GDO2 high at power-up, so a board with RX on 12 bootloops after a power cut until EN is pressed. It was the default RX pin. - RX defaults to GPIO35 on the original ESP32. Saved settings keep their pins. - The log warns each time the radio starts, and the radio settings show a warning, while TX, RX or MISO is on a pin whose level at reset can stop the chip booting (src/BootPins.h, data-src/js/pins.js).
