ESP32 Repeated Reboot Issue Arduino Shield Power Outage Detector

ESP32 repeated restart problem Arduino shielded power failure detector

The reason I found should be that the power failure detector was triggered. It is estimated that the power supply environment is inherently unstable. When the Bluetooth is turned on, the level instantly drops below the threshold. There is no capacitor on hand.
Then the restart failure should be a chip bug

Found an article How to disable brownout detector in ESP32 in Arduino

#include "soc/soc.h"#include "soc/rtc_cntl_reg.h"void setup() {WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); //disable detector//Your code}
