Aura Kobo Aura Deep Sleep command?

noonas · 03-21-2023, 07:32 AM

Hello there forum!

I am looking for a way to put my Kobo Aura (and Touch) in deep sleep and to WAKEW UP after a time or at a certain time.

I would like for my Dashboard to basically go in deep sleep during the night and during the day for periods of time and to wake up in the morning / evening.

I saw some posts but what I have tried does not seem to work and a link to some files rtcwake_kobo for example cannot be downloaded.

Any ideas?

The rtcwake binary in my KoboStuff package is patched to behave on recalcitrant i.MX boards, so it should Just Work (TM).

Just keep in mind you cannot enter suspend while Wi-Fi is enabled (that'll either hang or crash immediately or on wakeup, depending on the board).

See KOReader's suspend logic for all the gory details (which basically boil down to writing to 2 sysfs files, and some carefully tuned timing gymnastics. The sleep matters. A lot. As does the fact that this whole thing runs 15s *after* a suspend request). That's for suspend. We implement rtcwake ourselves, so I'll spare you that bit of hellscape

Awesome, I will read up on this - and report back.
This means I need to disable wifi, sleep, enable wifi once back up

Where can I find the KoboStuff package s'il te plaît

NiLuJe · 03-30-2023, 12:44 PM

It's over here: https://www.mobileread.com/forums/sh...d.php?t=254214

(When in doubt, it's linked in the Snapshot thread, which is pinned in the Kindle dev subforum).

thats cool, thanks - so I have installed (on a TOUCH), I try to test it but fail - it hangs in the wakeup and re-enable WiFi..

Here is the script i use to test.
#!/bin/sh
sh wifidown.sh
sync
sleep 1
echo "sleeping..."
echo "Good night ZZzz" > sleeptest.log
rtcwake -m mem -s 5
sleep 2
sh wifiup.sh
echo "Good morning" > sleeptest.log

it seems to shut the wifi off, and maybe sleep? but it does not come back on

What I am trying to do (in Python, but can be called as a SH.) is to put the Kobo to Sleep at various times of the day (and over night) and wake up and resume.

You don't actually need WiFi on all the time. It's just a battery drain.

noonas · 03-30-2023, 02:22 PM

Thanks, well for one of my projects it need to be on as I pull data from the internet every. 5 min

..

As for another project it does not need to be on at all and as I was told, you need to turn off WiFi before you sleep - hence the turn off, sleep - turn on again trick I was trying to pull and failing

NiLuJe · 03-30-2023, 02:59 PM

Make sure Wi-Fi is *actually* down (specifically the chip having been *powered down*, not just network down).

Try to see if it works without re-enabling Wi-Fi straight away.

Try to see if it works without dealing with Wi-Fi whatsoever.

Remember my warnings about timings and pain (specifically mind your timings during the wifi power teardown; and sleep more before tripping suspend).

. Refer to the KOReader scripts for details on all of the above.

Also, I don't quite remember how rtcwake works, but I would only use it to *setup* the alarm, not to actually trip the suspend. I'd handle that one myself (especially since you need to deal with the state-extended sysfs node, which is an ntx-special, so you *have* to do that yourself anyway).

Hi there,

Did you get this working in the end? I am trying to achieve the same thing. I really like the KoboHUB project you published also.

I see where Frostschutz was able to record and play back a screen tap.

Would it be feasible to record and play back a click of the sleep/power button?
Just tossing pasta at the wall...

NiLuJe · 08-11-2023, 02:57 PM

You don't need to record anything, it's standard: it's just EV_KEY:KEY_POWER (the SleepCover has a few different less obvious key codes depending on devices, though, not that it matters here), so just push a properly setup evdev `struct input_event`.

But that doesn't matter if you're not running Nickel (or, whatever), as there'll be nothing to actually handle that input event

Darn. Too bad that part of Nickel can't be left running, while a 3d party app takes over...

NiLuJe · 08-12-2023, 09:54 PM

Trust, me, you don't want that, it's more trouble than the perceived gains (see Kindles, where we keep powerd alive, and you get to enjoy weird mystical behavior that's way more annoying to deal with. It's great when it Just Works, but if you start trying to to wonky stuff, you're boned).

elinkser · 08-13-2023, 03:30 PM

Not to dispute what you're saying, since you've clearly walked the walk, but does KOReader not demonstrate that some kind of powerd, not necessarily Nickel's, could offer non-wonky functionality?
