sleep mode in ESP8266 shield

Hello there!, i recently buy the arduino ESP8266 shield, is there is any way to turn off the wifi shield, something like a sleep mode?

Almost definitely. Google is your friend.

I post here because i haven' t found anything in google, thanks anyway.

AT commands should work, as long as there is a way to wake it up again.

This interests me, too, so I did a google search on esp8266 sleep mode...and got 27000 hits. There is a lot of information out there. You found nothing useful?
