## Requirements & limits

- Requires a supported chipset, firmware profile and OS-specific backend. The README lists rooted Android 6–11, jailbroken iOS 12–14, specified macOS versions, Linux BlueZ excluding WSL, and a separate BTstack route.
- Monitoring is from the device running InternalBlue. Firmware protections can disable RAM read/write commands after driver initialization and require device-specific adaptations.
