Hi,
I have a problem when I upload sketch (example ESP8266_Shield_Demo) to Arduino:
Press any key to begin.
Error talking to ESP8266.
Error: 0
Looping forever.
I use Arduino Duemilanove. The switch on the ESP8266 is set to SW. It is very strange that everything was working fine until a few days ago. Now STAT LED doesn’t blink.
I’ve searched about this problem, but I couldn’t find anything. Any idea how to fix this? 
Thanks!](Imgur: The magic of the Internet)](Imgur: The magic of the Internet)
