I noticed that LED's connected to a GPIO start to glow during deep sleep.
Are the pullups activated?

Did you try the same while connected to an AP?
Does waking up the WiFi and reconnecting work?

In this post http://www.esp8266.com/viewtopic.php?f=28&t=2430&p=14178&hilit=connect+slow#p14178 the guy is experimenting with a battery powered ESP8266 with a sketch that regularly wakes up and connects to WiFi.

- Tue Apr 14, 2015 11:43 am #14490 Am I correct in thinking that after the sleep the ESP8266 RESETS rather than waking up?

It seems that deep sleep seems to consume the same power as pulling CH_PD low and both seem to reset/restart the sketch so I'm wondering what the benefit is of the deep sleep mode outside of being able to trigger it programatically.

- Tue Apr 14, 2015 3:54 pm #14511 It means that those of us that are developing battery powered sensors can put the esp8266 into minimal power mode between measurement & reporting cycles. For example I only want to check soil moisture levels once per hour.
