[question] What better to use "sleep" command or timer ?

@LVPVS, i have a few questions about your answer:
1. Why it better than systemd.timer ?
2. How it work in deep sleep mode ?
3. You mean adding this line to the service file?
4. @nemo - mean run script as user? If I will add @root, it somehow should ask about password?
5. Can I remove this line:
minute=0;everyDayOfWeek;everyDayOfMonth;everyMonth
And use for example "second=20" to run script every 20 sec?
Or for example how to change it if I want to run script every 6 days in specific time ?
Thanks

Hei,

1. It works in deep sleep mode. See calendar events.
2. See the previous pount.
3. Typing in CLI. Timedclient-qt5 is the built-in cron-alternative.
4. You can handle root within your script.
5. No. Instead, add everyHour and evetyMinutes, then seconds=20. Try day=6;hour=your_hour;minute=your_minute.

timedclient-qt5 --help is your friend. ;)

LVPVS over.

Thanks! Will try...

cron came to my mind as well, but be aware the possibility of phone overwriting your cronfile with every patch (don't know if they are altered or not on updates - don't see any reason for why they would alter them).

Thanks, I don't really want cause to people install cron...

You say both of them stops working in deep sleep mode, that means no differences what to use..
But I did a test with timer (20sec), started it and leaved phone for 35 min. When I checked log I found that my script started by timer every 20 sec and sent log 105 times... That mean or that the timer worked in deep sleep mode of the phone or timer prevented deep sleep mode ...
How I can check it ?

systemd timers? Were you charging the phone? The phone doesn't enter deep sleep while charging. Otherwise I guess the phone didn't enter deep sleep. Did the battery drain more than usual?

I don't know if battery drain was more or not, I did test only for 35 min. And every 20 sec my script sent notification to event screen. It was only for test. Usually it should check something and if it have changes, script should send notification to event screen if not, it just finish script action.

Hm, maybe the short delay time is preventing the phone from entering in deep sleep? That, or in latest SailfishOS systemd has been patched to correctly wake up the system, but I doubt that.

Try, just to be sure, with a more ample timeout (10 minutes for example). Anyway IMHO if you want to be sure to wake up the system even when it's in deep sleep timed is the best option.

Thanks for answer.
