Hi sorry for the late reply, Yh so looking at the datasheet and schematic, I can see that it brings the pin to ground so therefore when I set the esp_sleep_enable_ext0_wakeup, I choose the GPIO_NUM_2 and set it to low (0) and this just wakes up on its own when I do not press the button and I get the response saying Wakeup cause by external signal using RTC_IO. I am wondering if when the esp goes into deep sleep, that it brings the GPIO low automatically causing the wake up
