ESP32 Forum

Hi,
I flashed microPython on a generic ESP32 module (ESP2-WROOM-32D) that I've been using without any problems when coded with Arduino IDE. I tried to test with a very simple code the deepsleep function. This is the code I got from an example on the web at this link https://microcontrollerslab.com/micropy ... p-sources/
import machine
from machine import Pin
from time import sleep
led = Pin (2, Pin.OUT) #GPIO14 as output for LED
led.value(1) #LED is ON
sleep(1) #delay of 1 second
led.value(0) #LED is OFF
sleep(1) #delay of 1 second

# add a 10 second delay before ESP32 goes into deep sleep mode.
# it is just see the message on serial console
sleep(10) #delay of 10 seconds
print('Setting to Deep Sleep Mode')
machine.deepsleep(10000) #10000ms sleep time

However, I get a strange behaviour: the code is executed just ONCE, then when the deepsleep time has elapsed, the board seems to wake up, I get the following message on the shell (I'm using Thonny) and nothing else happens.
Since I am an old(74) newbie I would be very grateful if you could help me to solve this puzzle. Thanks for your help.
This is the message on the shell
>>> %Run -c $EDITOR_CONTENT

MPY: soft reboot

Waking up from deep sleep

Experiment with different durations for deep sleep to see if the behavior changes.

I believe the code executed only once because you may have not saved your code with the name main.py. The article you mentioned seems not to ask for this. If you save the code with that name you will see that it will be repeated over and over after waking up from deepsleep.
