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

Code: Select allESP.deepSleep(60000000);

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.

- Sat Jan 09, 2016 6:18 pm #38369 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().

- Sat Jan 09, 2016 6:26 pm #38370 Sorry, yes it was GPIO16.

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

- Fri Jan 15, 2016 11:44 am #38871 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.
