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.

If you put the ESP to deep sleep forever then exactly how do you expect it to wake up except someone or something else pulling the RST-pin? I mean, forever means literally that -- it'll go to deep sleep and stay in deep sleep. Also, why do you issue RF_DISABLED to it?

No. The flag RF_DISABLED doesn't change how deep-sleep works, the flag changes what happens when the device wakes up. In deep-sleep WiFi is always off, no matter what flag you give it.

i don't need it to use wifi until after i manually reset it

Then you don't want to use RF_DISABLED because that disables WiFi when you reset the device/it wakes up.
