RE: Added a new pulse oximeter importer...
(05-04-2022, 09:23 AM)kappa Wrote: I've captured the USB traffic. It's essentially the same commands and data format as is used on the BLE communication path, but with USB HID as the transport. The HID data contains the data length as the first octet and then the data for that packet, padded out to 32 bytes total. It should be relatively straightforward to adapt the o2ring bleak script to use pyusb or similar.
I appreciate that you're trying to help, but as a non-programmer and general python ignoramus, I wouldn't know where to start.
15 years ago, I used to do pretty well with autoitscript on winders but that was the "height" of my "programming" career 
RE: Added a new pulse oximeter importer...
I had a bit of a play trying to get it to work with python hidapi without any success so far. I think a cheap BLE usb adapter is probably the best approach for now if your device doesn't have built in BLE support.

RE: Added a new pulse oximeter importer...
I can confirm that it is working (beautifully) a little less than 20% of the time for me. I'm now running on a bluetooth 5x capable device
and success looks like this:

Questions:
1) What state should the o2ring be in when I run the script. (END counting down?, clock/unplugged/on?, on/charging/plugged into special factory serial/usb adapter?, on/charging/plugged into regular microUSB cable..?)
2) Can somebody confirm this command is valid? python3 o2ring.py -p '' -e ''
3) Can somebody confirm this command won't do ANYTHING besides download the bin files? (no changing setting on o2ring etc..?)
RE: Added a new pulse oximeter importer...
Has anybody tried to import Wellue Oxysmart PC60FW (ViHealth shows as Oxysmart 2132) data that is created by ViHealth. It does not follow the same formatting as the Wellue Ring.
RE: Added a new pulse oximeter importer...
I just looked at the website for this oximeter. This model does not store any data and requires it to be connected to a remote device as it is being used.
According to their website:
"Users can check their real-time data of Blood O2, PR, and PI on the app via Bluetooth. You can also view the statistical report of continuous data history on the app (Bluetooth ONLY).
*Data can ONLY be recorded on the app (not on the oximeter itself) and app needs to be running when recording data."
Based on its usage criteria, this is not a model that would be used in overnight data collection.

RE: Added a new pulse oximeter importer...
Hi everyone,
I stumbled upon this forum when exploring BLE on the Viatom O2 ring for a university research project. This code works like a charm, except I note exporting the raw trace isn't implemented yet. Are there any plans to do so, please? If not, would it be possible to get pointers as to where one would start with implementing this - eg if it's part of the same packet / under the same UUID?
Many thanks!
