Added a new pulse oximeter importer...

RE: Added a new pulse oximeter importer...
OSCAR Team...I've read this entire thread and am thoroughly confused about getting O2Ring data into OSCAR.

I have both a Contec and an O2Ring. I was successfully importing the Contec data into OSCAR, but I got tired of the big bulky machine on my wrist and the uncomfortable fingertip sensor. So I gave up on that, but I continue to use the O2Ring.

O2 ring is light and comfortable. I pull the data off as a CSV file every few days (unfortunately, the on-board memory only stores four days of data).

So, here's my question:
Is there any way to import the O2Ring CSV data into OSCAR?

Are simple step-by-step instructions available? Are any file translation steps required? I saw one reader used R to convert the data to a Somnapose file format, but I'm trying to avoid more steps.

It would be so great to just save the O2Ring CSV file and import it into OSCAR!

Thanks.

Steve

You can download Wellue's O2 Insight Pro software if you are using a Mac or Windows PC. You use that program to download the data to your PC. To import it in OSCAR, after importing that current day's data, go to Data ⇾ Import Viatom Data and select the files from the download directory on your PC. Viatom and Wellue are the same. You don't use the CSV file.

Thanks. I've been assiduously saving the CSV files for months. Is all that effort wasted?

I wrote a program to convert the one-second CSV data to probability cumulative distribution function which I then chart. It's a helpful way to see how I am doing.

I don't see why you couldn't turn the CSV back into binary data, though I don't know of anything that currently does this. Adding a CSV import function to OSCAR may be a better idea though.

I wasn't aware of bleak.  After looking at it, it uses asyncio which I have never used before, so there's going to be a bit of a learning curve for me if I want to switch to it.  I'm not sure if those man-hours would be better spent adding BT support directly to OSCAR...

I was already considering changing that, since Windows can't support anything other than *.ext filters, which thus required the non-native Qt file dialog on the platform, and since I'm planning for the overhaul of the oximetry wizard to allow selecting any files and leaving OSCAR to figure out what oximeter they belong to.

So, that's on my radar.

Modifying ViatomLoader::getNameFilter() to be `return QStringList("Date/time (20[0-5][0-9][01][0-9][0-3][0-9][012][0-9][0-5][0-9][0-5][0-9])") << "Viatom Binary Data (*.vld)";` makes it selectable, however it's still ignored when importing entire directories.  Any particular reason selecting multiple makes it import the entire directory instead of just the selected files?

Ah, the irony. OSCAR currently only understands the binary files. You can get those from the PC/Mac apps, from Android, and with some effort from iOS as well.

Yes: the current loader architecture doesn't support providing a list of files to import. You can only pass it a single path. (That's something I plan to change as part of a larger overhaul.)

The multiple selection as a proxy for the entire directory was a bit of a hack to work around some platforms' file selection dialogs being unable to select a directory.

Ugly wrinkles, but there you have it.

I'm not sure why it's ignoring the .vld files if you make that change, though. It should be using the filter both for the file selection and the import.

Ironic, indeed! CSV has been the lingua franca for data for 30 or 40 years and I can't use it to load data into OSCAR.

Laugh-a-lot

Is there an example of the CSV data around here? I'm making a converter but don't know what Viatom's data looks like as the Android app only exports as PNG (ugh). If someone could post the first few lines out of a .csv file it would be great.

The Android app stores the Viatom/Wellue raw data in a folder named, ViHealth, on the phone.

You can either export the directory contents via Google Drive or connect the phone to your PC and download the files.
