- Tue Apr 07, 2015 2:53 pm #13787 Thank you very much Bylonginus! I'll give it a try.

- Thu Apr 16, 2015 3:13 pm #14733 as much as I can see here: https://github.com/esp8266/Arduino/comm ... d680f63467 it will be included in the next release - or you can compile it by your own.

I'll give it a try, if I can find some time this weekend

- Sat Apr 18, 2015 3:53 pm #14938 Hello guys,

I´ve got the ESP 8266 - (1) with 8 Pins --> GPIO2 and GPIO0

If I use -

Code: Select allsystem_deep_sleep_set_option(4);
system_deep_sleep(60000000);

then it looks like, the ESP isn´t going into Deep sleep.

What I am trying to do, is this one with Arduino IDE:

He says -

One abnormal behaviour with this light is that it will stay triggered if the ESP8266 radio is on, the solution is to put it into deep sleep with the radio off after the message is sent.

But that doesn´t work - I think the deep sleep is not working.
Could you help me understand this?

My Code:

Code: Select all/*

 *
 *  You need to get streamId and privateKey at data.sparkfun.com and paste them
 *  below. Or just customize this script to talk to other HTTP servers.
