Hi.
The ESP8266 can be awakened from deep sleep using external wake-up and timer wake up.
Check this tutorial: https://randomnerdtutorials.com/micropython-esp8266-deep-sleep-wake-up-sources/

Great!
I’ll mark this issue as resolved.
If you need further help, you just need to open a new question in our forum.

Hi Sara,
I have the same issue when loading the deepsleep code and name as boot.py into the ESP8266 while connecting the RST pin to GPIO16.
It kept reboot from the deepsleep loop without accepting any else command such as STOP or Ctrl+D at Thonny.  
The only way to resolve it is to disconnect the jumb wire from RST to GPIO16 and reflash the board with new bin file.

Hi.
Can you better describe your issue?
You need to take into account that when the ESP goes into deep sleep mode, it won’t respond to Python commands because it is sleeping. So, it might be tricky to get a connection to the IDE when using that type of deep sleep.
