Works fine then. I just picked a small cap from bench

Code: Select allconst int sleepTimeS = 30;
ESP.deepSleep(sleepTimeS * 1000000);

When it hits it will reset and start the sketch again
The auto reset feature of arduino boards also use this technique on the DTR line and Sparkfun's "Thing" board uses it also .

Get you modules here:

However I found that a 100uF cap will prevent you from entering program mode.
A .01uF cap worked fine.
