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
