I have been trying to figure this out for a while with not much luck. I would like to wake up the ESP8266 from the deep sleep mode using a reed switch (or any switch). The problem is that the reed switch (or any switch) may generate multiple "events" and I need to reset the ESP-12E only once.

Is there a way to ignore all subsequent LOW signals applied to the RST Pin until the system is in the deep sleep mode again?

Thank you.

You may even be able to find a pin that the ESP itself turns high/low while it's awake and use that.

Thank you for replying. I would love to know how to wire of the pins to defeat the effect of the reed switch pulling the RST pin LOW.
