Conversation
- Add waitUntilReady() call before reading RTSP response - Add 5 second timeout for socket readiness - Fixes issue where devices weren't responding to RTSP requests - Resolves #26
- Always send OPTIONS request (RTSP standard) - Add logging to detect when device sends/doesn't send Apple-Response - Continue ANNOUNCE handshake even if device doesn't respond to challenge
- Track receivedAppleResponse flag in RaopClient - Only include rsaaeskey and aesiv in SDP if device responded to challenge - This fixes 403 Forbidden on devices that don't support authentication - Resolves ANNOUNCE request failures
- Some AirPlay devices don't support interleaved mode - Add detailed logging for SETUP response debugging - Still investigating 500 error on airsonos bridge devices
- Send rsaaeskey and aesiv fields regardless of Apple-Response - Change SDP connection address from device IP to 127.0.0.1 - Still investigating 403 Forbidden on native Sonos devices
- Fixed RTSP response reading by adding socket readiness wait - Fixed UDP port binding by properly cleaning up sockets between connections - Added TXT record parsing for RAOP server public keys - Added auth fields to SDP for ANNOUNCE requests - Added RAOP identity headers (Client-Instance, DACP-ID, Apple-Device-ID) - Issue #26 resolved: RTSP responses now being read properly - Airsonos bridge: OPTIONS 200, ANNOUNCE 200, SETUP still 500 - Native Sonos: OPTIONS 200, ANNOUNCE still 403 (auth field format issue)
- Added server public key parsing from RAOP TXT records - Implemented direct server public key usage in rsaaeskey field for native Sonos - Fixed Transport header format for airsonos bridge (added interleaved=0-1) - Added device-specific Transport header handling based on hostname - Native Sonos: Still getting 403 Forbidden on ANNOUNCE (auth field format issue) - Airsonos: Still getting 500 Internal Error on SETUP (protocol compatibility issue) Progress: - ✅ RTSP response reading fixed - ✅ UDP port binding fixed - ✅ TXT record parsing implemented - ✅ Auth fields added to SDP - ✅ Server public key handling implemented - ✅ Transport header format fixed - ❌ Native Sonos ANNOUNCE 403 (auth field format) - ❌ Airsonos SETUP 500 (protocol compatibility)
- Added proper RSA-OAEP encryption of AES session key for RAOP/AirPlay 1 - Generate random 16-byte AES session key and IV - Encrypt AES key with receiver's RSA public key using RSA-OAEP padding - Added OpenSSL RSA headers for key operations - Fixed fundamental authentication approach from sending public key to encrypted session key Issues remaining: - RSA key parsing from TXT record hex data still failing - Native Sonos ANNOUNCE 403 (RSA key format issue) - Airsonos SETUP 500 (protocol compatibility issue) Progress: - ✅ RTSP response reading fixed - ✅ UDP port binding fixed - ✅ TXT record parsing implemented - ✅ Auth fields added to SDP - ✅ Proper RSA-OAEP encryption implemented - ✅ Transport header format fixed - ❌ RSA key parsing from hex data - ❌ Native Sonos ANNOUNCE 403 (key format) - ❌ Airsonos SETUP 500 (protocol compatibility)
Major improvements to AirPlay connectivity: ✅ Fixed Issues: - RTSP response reading with proper socket waiting - UDP port binding failures with dynamic port selection - Authentication field inclusion in SDP for ANNOUNCE requests - TXT record parsing for server public keys - Device-specific Transport header handling for Airsonos bridges 🔧 Implemented Features: - XOR-based AES key encryption for native Sonos devices - Comprehensive automated testing framework - Device-specific handling for different AirPlay implementations - Enhanced logging and debugging capabilities 📊 Testing Results: - Airsonos bridges: OPTIONS ✅ 200 OK, ANNOUNCE ✅ 200 OK, SETUP ❌ 500 Internal Error - Native Sonos devices: OPTIONS ✅ 200 OK, ANNOUNCE ❌ 403 Forbidden - LIB-2833 device: OPTIONS ❌ 403 Forbidden (compatibility issue) 🎯 Remaining Work: - Fix Airsonos SETUP 500 Internal Error - Resolve Native Sonos ANNOUNCE 403 Forbidden - Investigate LIB-2833 compatibility issues The automated testing script provides comprehensive device discovery and connection testing capabilities.
- Remove outdated markdown files (BUILD.md, authentication docs, old issue tracking) - Delete duplicate/redundant test scripts (old test_airplay_devices.sh) - Add test_log.txt to .gitignore - Update README.md to consolidate information and remove dead links - Enhance README with testing documentation and platform-specific notes This cleanup consolidates project documentation into main sources: - README.md: Main overview and quick start - QUICK_START.md: Detailed getting started guide - USER_GUIDE.md: User documentation - CURRENT_STATUS.md: Current project status - PROJECT_SUMMARY.md: Project details - ALAC_IMPLEMENTATION.md: ALAC codec documentation Reduces documentation maintenance burden and improves clarity.
