OctoPi wpa supplicant clean file (OctoPi 0.17+)
# Use this file to configure your wifi connection(s).
#
# Just uncomment the lines prefixed with a single # of the configuration
# that matches your wifi setup and fill in SSID and passphrase.
#
# You can configure multiple wifi connections by adding more 'network'
# blocks.

When using ESP32 with the Arduino IDE, it does not support the native watchdog timer. The following gist does not use the official watchdog timer but employs a normal timer to reset the CPU if wdt_reset() is not called in time.
#include "esp32_wdt.h"
#include <esp32-hal-timer.h>
static hw_timer_t *timer = NULL;
/**
* iInterrupt service routine called when the timer expires.
*/
void IRAM_ATTR resetModule() {
ets_printf("watchdog reboot\n");
