Read the README.md and implement the full flow: - Connect BLE via VeepooDataManager - Parse HR, BP, SpO2, temp - Insert VitalsData into Room - After each insert, call SensacareApiClient to upload it - Display latest vitals in VitalsDashboardFragment - Handle BLE + location permission requests at runtime
Add a LiveData observer to VitalsDashboardFragment to display latest vitals from Room
Set up a foreground BLE scanning service that: - Starts when the app opens and runs in the background - Continues scanning and receiving data even when the app is minimized - Automatically reconnects to the last known Veepoo device if disconnected - Buffers data in memory and pushes it to Room and the API every 30 seconds
Create a coroutine in VeepooDataManager to throttle and buffer uploads (1 per 5 seconds max)
Add BLE reconnection logic if the device disconnects unexpectedly: - Monitor BLE connection state in BleConnectionManager - If disconnected unexpectedly, scan and reconnect to the last known device - Retry up to 3 times before showing a connection error in the UI - Auto-reconnect with configurable delays and attempt limits
Secure API communication: - Add a Retrofit Interceptor to include bearer tokens in headers - Store tokens in EncryptedSharedPreferences - Retry failed API requests up to 3 times with exponential backoff - If network is unavailable, queue data locally and sync when online
Add charting UI with MPAndroidChart to show last 24 hours of vitals - Line charts for heart rate, SpO2, and temperature - Bar chart for blood pressure (systolic/diastolic) - Real-time updates from Room database - Interactive charts with zoom and touch support
Create a one-time onboarding flow that: - Requests BLE, location, and notification permissions - Guides the user through pairing a Veepoo device - Saves the device MAC address for automatic reconnect - Includes optional vitals threshold setup
Add vitals flagging logic: - Heart rate > 120 or < 40: Show red alert - BP > 140/90 or SpO2 < 92%: Show warning icon on vitals card - Display alerts in VitalsDashboardFragment with status color - Individual vital alerts with warning icons - Overall alert status with background highlighting
Create a debug mode toggle: - Log BLE device scan results - Log characteristic UUIDs and values - Log insertions to Room and API POST responses - Display logs in a scrollable developer diagnostics fragment
Add a persistent connection status banner: - Display whether the Veepoo device is connected or disconnected - Use green (connected), yellow (connecting), and red (disconnected) indicators - Place the banner at the top of the dashboard fragment

# View logs adb logcat | grep "VeepooDataManager\|VitalsDashboard" # Check BLE permissions adb shell dumpsys bluetooth_manager
| Issue | Solution |
|---|---|
| BLE not scanning | Check location permissions |
| Device not found | Verify device is in pairing mode |
| Connection fails | Update UUIDs in VeepooDataManager |
| API upload fails | Check network and base URL |
| Build errors | Sync Gradle dependencies |
