- Sun Nov 13, 2016 4:33 pm #58100 When my ESP-12e goes into deep sleep my GPIO pins are defaulting to high even though they are low in the code right before sleep. I need them to be low during sleep, is there any way to do this?
Thanks

You can also select a low-power mode that does not force the uC to go into deep sleep... maybe just turn off the RF? That will take 80 - 120mA down to sub-40 mA.
