In 10 seconds
Any LoraFit ring with GATT service 56FF works, no app needed. When it goes quiet, see
Troubleshooting. Reading is safe; never type raw 39 / 67 or touch FEF5.
| question | answer |
|---|---|
| Which rings work? | any ring whose app is LoraFit and whose GATT has 56FF: SR116-xxxx, JY-Y3-xxxx, sold under many brands as "AI Recording / Translation Ring" with an HR3918. ring-cli scan decides by manufacturer id 0x594A. LoraFit's other family ("JieTuo", 6800/6801/6802) is a different chip — not covered |
| it stopped answering | empty scan, [] from hr, 100 % battery, ghost readings — every one has a one-line fix on Troubleshooting |
| Do I need LoraFit? | no — it was used once, as the source of the protocol. Unpair the ring from it or it will not answer anyone else |
| how long does a memo take to pull? | ~50 packets/s × 240 ms of audio each: a 6-minute memo streams in ~30 s. Deletion needs the 0x36 echo |
| two rings, one phone? | yes — each is its own device with its own label. On a Mac, one bridge per ring with -a |
| is it safe? | reading is. No reboot / factory-reset / unbind / OTA verb ships; ring-cli raw 39|67 is refused without --i-own-this-ring. Never write to FEF5 |
| is it legal? | interoperability research on hardware we own, nothing bypassed — SECURITY.md |
| where is the raw ledger? | the full ledger; the Protocol pages are the organised version |
