Any ideas?

Can you try again with the --record flag and the --debug flag and upload the log and the recording?

I have the same issue with a COLMI R02 ring. Below the logs and bin file.

@tahnok anything else we can try to debug this?

[tahnok]

I haven't had a chance to look at this yet, but I will when I get the chance. On discord I've had a report that maybe it's a different chip but same protocol (implemented slightly differently)

[tahnok]

I think I fixed this, can you try again?

[agamm]

Now I get:

[tahnok]

Oops, different issue introduced recently that I just now fixed if you want to try again

[agamm]

colmi_r02_util.exe scan
Found device(s)

empty.

[tahnok]

Scanning shouldn't have changed, you might have to try a few times to pick it up, it seems the scan misses the device. Can you try colmi_r02_client --address=YOUR_ADDRESS get-real-time heart-rate?
