I was wondering if it is possible to keep a programmed gpio-state during the deep-sleep. My purpose is to control another device which is connected to my Electron through a gpio pin. This device needs a high state to wake-up and sleeps when the state drops to a low. This is a problem because the low state becomes high (or float) during the deep sleep on Electron. Is there any possibility by using the Electron’s modules without adding any additional hardware?
Assume there is a LED connected to one of the D0. I would like to light up the LED, then go to deep-sleep for 10 seconds, and after coming back from deep sleep, disable the LED. This can only work if the chip keeps D0 high during the deep-sleep period.
Any help is appreciated.
