Sorry I wasnt clear in my reply - Yes, the Mac syncs via BLE. It appears BLE only. It won't find the device if the USB is plugged in. I was unable to get the app to find the device via USB.

How do you pair it with the oximeter? Does it automatically recognize it?

Also, I am unable to actually load those files, they're greyed out in the file dialog.

Are you going to Data > Import Viatom Data? You should be able to select an individual file, or the 20052C8643 folder.

There is no pairing - the desktop automatically recognizes the ring. Same with iOS. From what I've read, iOS is really locked down WRT what it'll communicate over bluetooth. The ring may just be blasting a modulated audio stream if talking to an Apple device.

I'm using "Import from a datafile saved by another program, like SpO2Review". This is with version OSCAR 1.1.0+e4d5a0d8 (FWIW - the version is kind of buried, I had to look in the application release notes to find it - it really should be on the first About screen.)

Um, the version number is in the title bar of the window. Smile

To import Viatom data, you need to go to the Data menu and select "Import Viatom Data".

See http://www.apneaboard.com/wiki/index.php...port#macOS

Aha, that worked! I was definitely taking the wrong path to load files - the Import Datafile button text was generic enough to addle my brain.
I was able to import data - I dont see any obvious correlation to assume the time is in sync, but I've only got one day's worth of Ring data to go off of and am still sussing out how to read the info.

Also, thanks for pointing me to the menu bar. My bad for not checking there Smile

I have some BLE sniffing boards/software from when I was trying to get beacons working (I didnt get very far), I might try and see what I can read from the Ring. Maybe it's in Beacon mode?

It shouldn't be off by more than ~4s assuming you synchronized its clock with either your phone or your computer.

The 4s question is due to the uncertainty of whether the starting timestamp indicates the time that the oximeter began recording or the time that the first measurement was recorded. So it might be right, or I might have guessed wrong.

Speaking of which, it's totally reasonable for you to have tried other import buttons. For 1.2 I'm hoping to unify the oximetry import and make it a little more reliable. But I didn't want to wait that long to support Viatom oximeters.

The SleepU uses a CH34x USB-to-serial bridge. macOS 10.14 Mojave and newer have the driver built in. For older version of macOS, see:
