How do you know that the CPU is started after deepsleep timer expire? Is there any proof of this? It is from time to time described as an hardware bug, but I've never get more info about this.

I checked with a USB meter and realized that it doesn't start after the timer finishes (Normal use consumed 0.07A and deepsleep consumed 0.02A). It does reset when I remove the RST--GPIO16 connection. But that still means I need to do it manually, and the code does not reset on its own.

@chamathkv: no, esp arduino starts with "void setup()" after deepsleep

@Pablo2048: because there is bootloader msg @74880 after deeplsleep timer expires w/o gpio16-rst

Yes, you are right, it starts with void setup() just that in my case it doesn't start at all. It just stays in deepsleep even after the timer. (RST--GPIO16) connection is still connected btw.

Thanks for the point...
