lightsleep() not working properly Pi Pico WH v1.24.0
Port, board and/or hardware
Raspberry Pi Pico WH
MicroPython version
MicroPython v1.24.0 on 2024-10-25; Raspberry Pi Pico W with RP2040
Reproduction
Attempt following code, both with lightsleep() having no ms argument and one with:
import machine
from machine import Pin, deepsleep, lightsleep
def wake_up(pin):
# Handle wake-up logic here
led.toggle()
print("Button pressed, waking up!")
# Configure buttons
button = Pin(11, Pin.IN, Pin.PULL_UP) # Example pin
led = Pin(20, Pin.OUT)
led.on()
# Set up interrupt
button.irq(trigger=Pin.IRQ_FALLING | Pin.IRQ_RISING, handler=wake_up)
# Go to sleep until a button is pressed
lightsleep()
Expected behaviour
Expect LED to react to button press when asleep and execute wake_up function. LED is on by default. LED should toggle/turn off when button is pressed down, both when machine is asleep and not asleep.
Observed behaviour
USB power tester indicates that the board sleeps only when NO MILLISECONDS ARGUMENT IS SPECIFIED.
When milliseconds ARE SPECIFIED, board does not appear to sleep as power consumption does not drop according to the USB tester. The board continues to work at full power, and the LED reacts to the button.
When NO MILLISECONDS ARE SPECIFIED, board appears to go to sleep (reducing power from >10ma to 0-1ma. But button does not do anything to LED.
Additional Information
I have tried adding the wake argument to button.irq, but Micropython says that extra keyword arguments are present.
I understand sleeping may have issues on the Pico W models. I have also tried turning off WiFi/setting the pin associated with Wifi to "low". That does not seem to have any impact whatsoever, since my code never explicitly turns Wifi on

RP2350 / Pico 2 machine.lightsleep not working correctly
Port, board and/or hardware
Pico 2 / RP2350
MicroPython version
MicroPython v1.24.0-preview.201.g269a0e0e1 on 2024-08-09; Raspberry Pi Pico2 with RP2350
Reproduction
- Install latest Firmware from https://micropython.org/download/RPI_PICO2/
- Implement
machine.lightsleep(5000)in your code - Run code.
Expected behaviour
Expected Pico 2 to enter lightsleep mode for 5 seconds, then continue to next bit of code.
Observed behaviour
lightsleep is maybe entered for a cycle or so, but code carries on and never stops executing for any time value I enter for lightsleep.
Additional Information
Complete code example:
# Lightsleep MicroPython example.
from machine import Pin
import time
led = Pin(25, Pin.OUT)
while True:
led.toggle()
time.sleep_ms(5000)
led.toggle()
