I have an existing Android application that already works with an earlier Bluetooth Low Energy device. I am now moving to new hardware and need the app updated so it can discover, pair with, and communicate seamlessly with this new BLE board. Your main objectives are: • Integrate the new GATT profile and confirm stable read/write operations. • Enable real-time data synchronization between the phone and the device. • Maintain full device-side control functions (start/stop actions, parameter changes, etc.). Please work in Android Studio; the current codebase is structured for that environment and all future maintenance will stay there. I will supply the existing project, the new device’s UUID map, and test procedures. Final deliverables are the updated source project, an installable APK, and a brief change log confirming that data sync and control commands have been validated on at least two Android OS versions.
