Current status of lightsleep/deepsleep?

[jdaviderickson]

Hello, I am wondering about the current status of lightsleep and deepsleep for the RP2040/Pico2w. I notice with version 1.25 lightsleep exits immediately. If I use it without parameter, the USB breaks. deepsleep seems to require a reset. I am working on a low power(battery) application. I guess an alternative is to use the C library for low power and create a custom Micropython? Or should I just use C? Any advice appreciated!

There is an issue with lightsleep with network module, here, https://github.com/orgs/micropython/discussions/17185

The deepsleep might be just forwarding to lightsleep, ref here #12102

I am finding that C appears to be a better choice foraccessing low power modes. I've been using Thonny and micropython over USB. I think I'm going to move to the Arduino IDE with a debug probe and finish development in C.  There is a C library called picoextras that apparently has support for the low power modes as well as managing the clock sources for power management. I might end up switching to ESP32 for the final version rather than Pico. Good for prototyping but not so much for deployment. On Aug 7, 2025 12:22 AM, Jon Nordby ***@***.***> wrote: There is an issue with lightsleep with network module, here, #17185 The deepsleep might be just forwarding to lightsleep, ref here #12102 —Reply to this email directly, view it on GitHub, or unsubscribe.You are receiving this because you authored the thread.Message ID: ***@***.***>

Just found out that Arduino doesn't support all the necessary libraries for the Pico. So I guess it's off to VSCode.
