Good morning 👾

I'd like to fetch data via BLE (Python or Swift) from a cheap smart ring that can be reverse engineered or that is already RE'd. Pulse, oxygen levels, gyroscope, button would be very useful. I'd like to build a python or swift library.

Thank you for any input =)

I was looking into Colmi already but thought maybe knew some hidden gem :)

Checking the Colmi watches

The nice thing about Colmi is there's support for it in Gadgetbridge, so it will likely be easier to tinker with
