Comprehensive 15-section technical reference for the DWARF telescope
protocol, consolidating everything learned from APK reverse-engineering
and live hardware testing:
1. Network architecture (BLE, WebSocket, RTSP, HTTP)
2. BLE discovery handshake (DwarfPing/DwarfEcho)
3. WebSocket control layer (connection, frames, lifecycle)
4. WsPacket envelope (all 8 fields explained)
5. Command routing (module_id derivation by cmd range)
6. Response model (3 patterns: reply, notification-only, fire-and-forget)
7. Notification system (~130 notification types, fan-out)
8. Camera subsystem (lifecycle, params, capture modes)
9. Motor subsystem (joystick polar coords, limits, init, gotchas)
10. Focus subsystem (commands, position tracking)
11. Astro subsystem (calibration, GoTo, stacking, EQ solving)
12. Preview/RTSP (URLs, prerequisites, ijkplayer options)
13. Device models & feature gating (6 models, feature matrix)
14. Protocol quirks (10 gotchas discovered during live testing)
15. Error codes (motor, camera, astro, general)
