Hello, everyone!
I`m new user this hardware and software and I need help, please. I buy nodemcu v3 ESP8266, if this important, on aliexpress.
(ctrl+D):
>>>
PYB: soft reboot
WebREPL daemon started on ws://192.168.4.1:8266
Started webrepl in normal mode
hello!
MicroPython v1.10-8-g8b7039d7d on 2019-01-26; ESP module with ESP8266
Type "help()" for more information.
>>>
Now in main.py:
print("hello")
Now I try use deepsleep and awake.
1.
Connect RST pin to D0 (GPIO 16), now with a 470 ohm resistor, before that just wire.
2.
Connect (I`m use ubuntu), to serial port sudo picocom /dev/ttyUSB0 -b115200.
3.
implement this code:
[CODE]
>>>
>>> import machine
>>> rtc = machine.RTC()
>>> rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP)
>>> rtc.alarm(rtc.ALARM0, 10000)
>>>
>>> machine.deepsleep()
[/CODE]
LED on the board blink once, device not load. If I press to RST-button afte machine.deepsleep(), but before ALARM0 work, LED on the board blink once, device not load. If I press to RST-button - LED blink twice and device normal boot and work.

On windows OS, use putty to connect COM3 speed 748800.
connect to wifi this board, and use webREPL:
[CODE]
>>> import machine
>>> rtc = machine.RTC()
>>> rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP)
>>> rtc.alarm(rtc.ALARM0, 10000)
>>>
>>> machine.deepsleep()
[/CODE]
afte 10 sec in putty:
[CODE]
ets Jan 8 2013,rst cause:2, boot mode:(3,6)
[/CODE]
and it's all.
But if I press RST button:
[CODE]
ets Jan 8 2013,rst cause:2, boot mode:(3,6)

[/CODE]
If I connect wired to RST and connect/disconnect to GRD, rst cause:2, too.
What can I do to make deep sleep work?
Thanks so much for any help.
