SleepyHead minimum session length - midwestguy - 01-23-2022
Geer1 is trying to check on my machine's functioning.
What will SleepyHead accept as a minimum-length session?
Thanks,
Harv (yeah, still stuck with SH)

There's a preference to ignore sessions shorter than X. I think you can set that to zero, I forget its default -- maybe 5 minutes?

Excellent. Didn't know it was settable.
Thanks, sawinglogz!

I think it depends on whether you are using SH1.0 or earlier, or v1.1.
I think in both, the minimum length is 1 minute, which is the resolution of the mask on/off fields. If the mask off time comes within the same minute as the mask on time, the session length is zero, and SH ought to ignore but doesn't. If the off time comes after the minute tick, you have a one minute session.
The gap between sessions is different in 1.0. Any break will cause new detailed data files to be started, and SH 1.0 will treat that as a new session. in SH 1.1 (and OSCAR) the mask on/off times delineate sessions, and the machine seems to require more than one minute gap to declare a mask off/on pair, and always creates new detailed data files.
Probably more than you wanted to know... also, I haven't looked at the v1.0 resmed loader code in any detail, so I could be wrong.
By the way, if you have the X-Code CD for your version of OS/X, you may be able to compile and build OSCAR yourself. OSCAR started off using QT 5.7, and still works with QT 5.9. No guarantees, but we haven't tried to obsolete old QT versions (yet).

I'm leery of compiling and building my own personal OSCAR. Could be a real time sink.
Thanks for the explanations, pholynyk.
