The stored data can be retained between deep sleep cycles. Total size of RTC user memory is 512 bytes, so offset + sizeof(data) shouldn’t exceed 512. (GPIO16 needs to be tied to RST to wake from deepSleep.)ĮSP.rtcUserMemoryWrite(offset, &data, sizeof(data)) and ESP.rtcUserMemoryRead(offset, &data, sizeof(data)) allow data to be stored in and retrieved from the RTC user memory of the chip respectively. mode is one of WAKE_RF_DEFAULT, WAKE_RFCAL, WAKE_NO_RFCAL, WAKE_RF_DISABLED. Serial1.Some ESP-specific APIs related to deep sleep, RTC and flash memories are available in the ESP object.ĮSP.deepSleep(microseconds, mode) will put the chip into deep sleep. Gpio_pin_wakeup_enable(GPIO_ID_PIN(LIGHT_WAKE_PIN), GPIO_PIN_INTR_LOLEVEL) This type of sleep mode, as you can see in the video permit to get 20mA of power to the device, to obtain better power saving you must set the wake up via GPIO.
