ESP8266 Community Forum

Hi,
I'm running an ESP8266 from batteries and will run some code just once when powered up and then I want to send the ESP to a deep sleep permanently can I do this by using but not have GPIO15 connected to the reset pin, will this put the ESP to sleep until the power has been removed and switched on again.

It's GPIO16, not GPIO15, that needs to be tied to reset. Also, yes, at least that's how my ESP8266 works: if GPIO16 is not tied to reset the board won't wake up from deepSleep().

Sorry, yes it was GPIO16.

Thanks for answering, I'll give it a try tomorrow.

should use ESP.deepSleep(0); to sleep forever, rather than 600000

i'm a bit stumped though, as i cannot get waking to work with gpio16 tied to RST (a button on the RST pin works though) and ESP.deepSleep(0, RF_DISABLED); i can't get to wake at all without pulling the power.
