If the target ESP-01S is in deep-sleep, pressing the RESET wakes it and boot.py is executed. However, I've read several articles that refer to connecting a wire from the RST pin on the ESP-01S to the GPIO16 pin (physical chip pin 8, labeled XPD_DCDC) being necessary to wake from deep-sleep. As I have not found that to be necessary, is there any reason, or difference in return from deep-sleep to be gained by wiring the RST to GPIO16?
UPDATE: Shortly after making this post I discovered that the GPIO16 is not an input, it's configured as an output for the Real-Time-Clock. By connecting GPIO16 to the RESET the RTC can wake the ESP8266. None of the articles I read that mentioned connecting the two together made it clear that it was in lieu of manual activation.
I immediately replied to my own post, but for some reason this forum doesn't allow real-time responses; they take up to two days for approval.
