+
+## Project Overview
+
+POWERFUN Settings App - A React Native application for managing POWERFUN fitness devices (power meters, paddle sensors, T5 trainers) via Bluetooth LE. Supports device scanning, information reading, calibration, firmware updates (DFU), and spindown calibration.
+
+## Build Commands
+
+```sh
+yarn start          # Start Metro bundler
+yarn android        # Run on Android
+yarn ios            # Run on iOS
+yarn build-a        # Android release build (set NODE_OPTIONS=--openssl-legacy-provider)
+yarn lint           # Run ESLint
+yarn test           # Run Jest tests
+yarn clean-a        # Clean Android build (cd android && gradlew clean)
+```
+
+## Architecture
+
+### Navigation Structure
+- React Navigation Native Stack Navigator
+- Entry: SplashScreen → HomeScreen
+- Three device paths from HomeScreen: Power Meter, Paddle, T5 Trainer
+- Each path: ScanScreen → InfoScreen → DfuScreen
+- T5 has additional: SpindownScreen
+- Global: SettingScreen, PrivacyScreen
+
+### Screen to File Mapping
+| Screen | File | Purpose |
+|--------|------|---------|
+| HomeScreen | src/HomeScreen.tsx | Device type selection (3 buttons) |
+| ScanScreen | src/ScanScreen.tsx | Power meter BLE scanning |
+| ScanScreen2 | src/ScanScreen2.tsx | Paddle BLE scanning |
+| ScanScreen3 | src/ScanScreen3.tsx | T5 trainer BLE scanning |
+| InfoScreen | src/InfoScreen.tsx | Power meter info, real-time data, calibration, power trim |
+| InfoScreen2 | src/InfoScreen2.tsx | Paddle boat type settings |
+| InfoScreen3 | src/InfoScreen3.tsx | T5 trainer weight, bike type, ERG smoothing |
+| DfuScreen | src/DfuScreen.tsx | Nordic DFU firmware upgrade |
+| SpindownScreen | src/SpindownScreen.tsx | T5 trainer spindown calibration |
+| SettingScreen | src/SettingScreen.tsx | Language, privacy policy |
+| PrivacyScreen | src/PrivacyScreen.tsx | Privacy policy content |
+
+### Bluetooth LE Architecture
+- Library: `@systemic-games/react-native-bluetooth-le`
+- Central API for scanning, connecting, reading/writing characteristics, subscribing to notifications
+- Device name prefixes for filtering:
+  - Power meters: `PF-PM5-` or `POWERFUN-`
+  - Paddles: `PF-STK-` or `POWERFUN-`
+  - T5 trainers: `PF-T5-` or `POWERFUN-`
+- RSSI filtering: devices below -90 dBm are filtered out
+
+### BLE Service/Characteristic UUIDs
+| Service | Characteristic | Purpose |
+|---------|----------------|---------|
+| fff1 | fff2 (write) | Custom power meter commands |
+| fff1 | fff3 (notify) | Custom power meter responses |
+| 180a | 2a25 | Serial number |
+| 180a | 2a28 | Firmware version |
+| 180a | 2a27 | Hardware version |
+| 180f | 2a19 | Battery level |
+| 1818 | 2a63 | Cycling power measurement (real-time) |
+
+### DFU Architecture
+- Library: `@systemic-games/react-native-nordic-nrf5-dfu`
+- Firmware manifest: `https://powerfun.oss-cn-shanghai.aliyuncs.com/yecongdfu/latest.json`
+- Firmware versions parsed as `hardware.iteration.build` (e.g., "1.23.456")
+- Upgrade only allowed when server iteration > device iteration
+- Downloads firmware zip to cache, then initiates DFU
+
+### i18n Architecture
+- Library: i18next with react-i18next
+- Languages: Chinese (zh) and English (en)
+- Storage key: `@app_language` in AsyncStorage
+- Translation files: `src/i18n/locales/zh.json`, `src/i18n/locales/en.json`
+
+## Key Implementation Notes
+
+### Bluetooth Connection Lifecycle
+- InfoScreens connect to device on mount, disconnect on navigation away (except when going to DfuScreen)
+- Connection status listener: `Central.addListener("peripheralConnectionStatus", handler)`
+- Device ready state: `connectionStatus === "ready"`
+
+### Real-time Data Parsing (Power Meter - 2A63)
+- Byte 2-3: Power value (little-endian)
+- Byte 4: Left balance (0.5% units)
+- Byte 5-6: Cadence revolution count (little-endian)
+- Byte 7-8: Cadence timestamp (1/1024 second units)
+- Cadence RPM = (revolution_diff / time_in_seconds) * 60
+
+### Power Trim
+- Range: 50-200 (represents 50%-200%)
+- Stored as: value * 100, sent as 2-byte little-endian
+- Protocol: Write [0x02, low, high] to FFF2, then write [0x04] to trigger update
+
+### Calibration
+- Command: Write 0x05 to FFF2
+- Response: Read from FFF3 notify (0x05 + 2-byte value in 0.1 units)
+- Timeout: 5 seconds
+
+### Firmware Version Comparison
+```typescript
+// Version format: "hardware.iteration.build" (e.g., "1.23.456")
+// Only iteration is compared for upgrade decision
+// hardware mismatch → cannot upgrade
+// server iteration <= device iteration → no upgrade needed
+```
