# sr16-bridge: reconstructing SR16 smart-ring BLE history sync

> sr16-bridge reconstructs the SR16 smart ring's vendor BLE history-sync protocol in a local Python client. It reassembles segmented notifications, checks CRCs, decodes heart-rate records and imports HCI snoop traffic into SQLite; probe logs record the observed message behavior.

## Requirements & limits

- **Prerequisites:** macOS with Python 3.11 and an awake, unpaired SR16 ring nearby.
- **Testing evidence:** The author reports history-sync decoding through session 17; the session-17 notes say some activity metrics were absent from the captured BLE sync data.
- **License:** No licence file in the repository.
