+# DWARFLAB Protocol Documentation
+
+Reverse-engineered communication protocol for **DWARF series smart astronomical telescopes** (DWARF 2, DWARF 3, DWARF mini, DWARF 4, DWARF DRAGON), extracted from DWARFLAB APK v3.4.0 (build 629).

+1. **BLE** — Discovery, authentication, WiFi configuration
+2. **WebSocket** — All telescope control, notifications, keepalive
+
+## Security Notes
+
+- BLE password: 8-63 chars, no spaces, default `DWARF_12345678`
+- Same password used for both BLE auth and WiFi
+- WebSocket is unencrypted (`ws://`, not `wss://`)
+- Session magic bytes: `DWfvuu]`, `4dwf`, `aRdWf`, `DWFq`, `dwFS`, `DwftA`, `DWFL`
