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 =)

Maybe a Colmi smart ring, versions ranging from 13 to 30 €?

I got a Colmi Smartwatch for 13 €. It doesn't integrate into the standard Android Health thing but seemingly uses its own protocol or sth.
