Diagnose common setup, registration, and streaming issues in DAT SDK integrations.
Device not connecting?
│
├── Is Developer Mode enabled? → Enable in Meta AI app settings
│
├── Is device registered? → Check registration state
│
├── Is device in range? → Bluetooth on, glasses powered on
│
├── Is the app registered? → Check registrationStateStream()
│
└── Stream stuck in waitingForDevice? → Check device availability
Developer Mode must be enabled for 3P apps to access device features.
waitingForDevicestopped → waitingForDevice → starting → streaming → stopped
Ensure compatible versions of SDK, Meta AI app, and glasses firmware. See version dependencies for the current compatibility matrix.
| Issue | Workaround |
|---|---|
| No internet → registration fails | Internet required for registration |
| Streams started with glasses doffed pause when donned | Unpause by tapping side of glasses |
| [iOS] Meta Ray-Ban Display: no audio feedback on pause/resume | Will be fixed in future release |

private let logger = Logger(subsystem: "com.yourapp", category: "Wearables")
