DSP8266 does not come out of deep sleep

[carlosmaug]

Hi
When DSP8266 enters in deep sleep it never come out, I just get this string "��rl�l��|��쒒b�nnlnn�bp��rr��b�n" and it hangs for ever unless y disconnect and reconnect CH_PD (normally connected to 3.3V) or I make a reset.

Here is the output I get from the console.

Hi All
I found the answer in this web page http://www.esp8266.com/viewtopic.php?f=6&t=535
GPIO16 exists: it's XPD_DCDC you have to connect reset to this pin of the chip to come out of deep sleep.
It is not an easy task...

Hi, thanks for raising this issue and attaching the circuit diagram and picture. I've linked them from the readme and hopefully made it a bit clearer.

Hope it all works now.
