- Generic parser now supports food scale weight ranges (1g-15kg)
with candidates for gram, 0.1g, and 0.5g divisors
- WebSocket sends grams (unit: 'g') for weights under 15kg
- MainActivity displays grams for food-scale readings
- Enhanced debug: raw byte dump on decode failure with index/decimal/hex
- versionCode=5, versionName=1.6.0
BREAKING FIX: 'always 1.8 kg' — the old brute-force parseGeneric was
matching noise bytes. Replaced with protocol-specific parsers:
Protocol support (from openScale research):
- Bluetooth SIG 0x2A9D/0x2A9C (standard weight/body composition)
- QN/Yolanda/FITINDEX (opcode 0x10 weight, 0x12 scale info)
- 1byone/Eufy (0xCF header, LE weight at bytes 3-4)
- Hesley/YunChen (20-byte body composition frame)
- Renpho proprietary (0x2E header on 0x2A9D)
- Safe generic fallback (stricter: min 4 bytes, min 2kg, unstable)
Body composition fields: fat%, muscle%, water%, bone, BMR/kcal,
impedance — all displayed when available.
Debug panel fix: capped at 150 lines, UI updates throttled to 200ms
(was: unbounded StringBuilder updated on every BLE notification = freeze).
Auto-reconnect: saves last connected device MAC to SharedPreferences,
auto-starts scan on app launch and connects when saved device found.
GATT service discovery: now explicitly subscribes to QN (FFE0/FFE1)
and custom FFF0 (FFF4 or FFF1) characteristics in addition to
standard Weight Scale and Body Composition services.
ScaleProtocol state: resetState() called on new connection to reset
QN weight divisor (100 or 10, learned from 0x12 info frame).
- Show device names from ScanRecord (fixes MAC-only display)
- Show 'Senza nome' for unnamed devices instead of hiding them
- Show proximity (Vicino/Medio/Lontano) instead of raw dBm
- Sort scan results: scale-likely devices first (keyword + UUID scoring)
- Add debug panel (toggle with 🐛 Debug button):
shows GATT service map, raw hex bytes, parse attempts
- Expand parseGeneric: all 2-byte windows × 3 resolutions × LE+BE
(adds 0.1f and big-endian candidates – common in cheap consumer scales)
- Log GATT services/characteristics after connection
- Log raw hex bytes on every characteristic notification
- Add .github/workflows/build-scale-gateway.yml
Triggers on push to main (evershelf-scale-gateway/** path filter)
Builds debug APK with Gradle/JDK 17, renames to evershelf-scale-gateway.apk
Creates/updates 'latest' GitHub Release so the direct download URL resolves
- Bump web app version v1.2.0 -> v1.3.0 (index.html)
- Bump Android versionCode 1->2, versionName 1.0.0->1.3.0 (app/build.gradle.kts)
- Add evershelf-scale-gateway/ Android app (Kotlin):
