BLE testing depends on real Android hardware and runtime permissions.
Built explicit permission, Bluetooth enabled, scan, connect, read, and write states so device behavior could be tested step-by-step.
Projects
BLE Connected Device App
BEY-T Smart Lock
BEY-T is a Flutter mobile app for onboarding, connecting to, calibrating, and controlling a Bluetooth Low Energy smart lock. The app reads lock state, door state, and battery status, then sends lock/unlock commands to the device.

Architecture
Technical decisions
Separated BLE operations into `BleCubit` and lock business logic into `LockCubit`.
Mapped BLE services and characteristics for lock state, door state, commands, battery, and calibration.
Used componentized Flutter screens for onboarding, calibration, lock details, home, locks, and shared cards.
Kept device communication local to the mobile app because no backend integration was evident in the source.
Problem solving
Challenges and solutions
Lock state required translating numeric BLE values into user-facing door/lock conditions.
Modeled lock and door conditions in Cubit logic and rendered clear connected, locked, unlocked, open, and battery states.
