0.1.0 — 2026-09-19 — the ring, freed·

The whole reverse-engineering effort landed in one day, in four parallel lanes (APK static analysis, live HCI capture, driver, tiny health platform).

  • protocol — frame format FE FC | cmd | total | index | len | payload (u16 LE, no checksum), GATT service 56FF (write 33F3, notify 33F4), MTU 512, no authentication. 40+ commands mapped from the LoraFit APK and confirmed byte-for-byte against an HCI snoop of the vendor app itself.
  • live proven — device info (37), name (68), features (55), battery + charging (6), step snapshot (29), set-time (1, local epoch seconds), app info (26), HR open/close/tick (7/8/11, end marker 17), auto-HR (30), history (33/34/36 → terminators 42/43/45), alarms (69), vibrate (4), heartbeat (62).
  • audio — on-ring voice memos: 0x2F state → 0x3D count → 0x40 → 0x34 stream (12 × 40-byte Opus frames per packet, 16 kHz mono, 20 ms) → 0x36 echo deletes. Pure-python Ogg Opus muxer; .wav via ffmpeg.
  • driver — ring-cli (scan, gatt, info, battery, steps, settime, find, alarms, hr, spo2, temp, sleep, sync, raw, listen, audio-state/pull/post/ record, handshake, bridge). macOS transport attaches to the system-held bonded link in ~10 ms instead of scanning.
  • bridge — long-running daemon: handshake → history → memo sync → live vitals → POST /api/health/ingest and /api/health/media on tiny.technology. Pidfile guard, pause-file handover, cradle-artefact tagging.
  • capture tooling — Pixel HCI snoop recipe (tools/capture.sh), btsnoop → ATT JSONL decoder (tools/btsnoop_att.py), GATT dump.
  • tiny — use_ring.mjs local agent tool; health platform, iOS/Android gateways and inbox voice memos live in the tiny app (documented under tiny in the docs).
  • docs — this site, README, protocol reference, community files.
