This section describes how ESP-IDF uses these features by default. The ESP32 integrates a Bluetooth connection controller and Bluetooth baseband, which perform baseband protocols and other low-level link routines, such as modulation demodulation, packet processing, bit-stream processing, frequency hopping, etc. Through IO MUX, RTC IO MUX and the GPIO matrix, peripheral input signals can be from any IO pins, and peripheral output signals can be routed to any IO pins. Upon exit from Light-sleep, the digital peripherals, RAM, and CPUs resume operation and their internal states are preserved. GND is a ground pin of ESP32. There is RTC GPIO support on the ESP32. If you want to "preserved" the RTC time use an external RTC module; use an external GPS module (requires to be outdoor); call an NTP service to set the time after reset;. ESP32 conflicts with thinger io due to the fact that you cannot use two wifi libraries at the same time with time. The following GPIOs can be used as an external wake up source. In particular, for ESP32-WROVER module, call rtcgpioisolate(GPIONUM12) before entering deep sleep, to reduce deep sleep current. My dirft after 15 hrs is -8 Minutes.
