Deepsleep acting weird

[Slythy]

Is there a limit to what machine.deepsleep(xxx) can be? I am trying to deepsleep for 24hours and then it wakes up but it does not function doing that.

`first_delay = 2 * 3600 * 1000

pulse1_interval = 24 * 3600 * 1000

prog_interval = 12 * 3600 * 1000

prog_pulses = 14

third_gap = 30 * 60 * 1000

fourth_gap = (1086400 + 23600 - (786400 + 143600 + 30*60)) * 1000`

if I delete the 3600 from it then it all functions correctly. I would assume that machine.deepsleep() is 32bit?

If (and I didn't check the sourcecode) the system relies on the HW Timers and Alarms, then the max time for a wakeup alarm is 2³² × 1E-6s. Which in turn results in almost but not quite 4296s.

Nah, one would have to look into the SDK function. Let's say I'd put my money on the one hour eleven minutes limit.

Awesome. I will do 1hour sleep limits and just do cycles of them. Thanks so much!

I have it as machine.deepsleep(1800000) and it doesnt seem to have woken up. which is 30 mins. Any reason you can think why it wouldnt like that?

machine.deepsleep(1800000)

That should work, at least under v1.25.0. What firmware are you running? There have been some changes to deepsleep/lightsleep over the last couple of releases.

If you supply too big an argument to deepsleep, it immediately fails with ValueError: sleep too long. The largest value I could send to my Raspberry Pi Pico running v1.25.0 was 4294966: that's (2**32 // 10**3) - 1 milliseconds.

I've been running tests on a Raspberry Pi Pico with a DS3231 RTC attached to get an idea of how long deepsleep() really sleeps for. It's pretty close to what you ask it to, as long as it's ≤ 4294966 ms.

I ended up having a weird issue where it wasnt closing the file after writing and then going to deepsleep. Once fixed the 30 min sleep works fine.

Thanks so much for all the help Everyone!
