# 🚀 Aerofly FS 4 Bridge DLL - Bidirectional Integration Project
Hello community! I want to share the progress of an exciting project we’re developing to expand Aerofly FS 4’s integration capabilities.
## 📋 What are we building?
A **complete Bridge DLL** that enables bidirectional communication between Aerofly FS 4 and external applications (Python, C++, web apps, etc.).
## 🎯 Current Status: **FUNCTIONAL** ✅
### ✅ **WHAT’S ALREADY WORKING**
**📊 Data Reading (Ultra-fast):**
- **285 variables** from the SDK completely mapped and accessible
- **Shared Memory interface**: Sub-millisecond latency for real-time data
- **TCP JSON streaming**: Network-ready for remote applications
- **Simultaneous multi-client** support
**🎮 Command Writing (Bidirectional Control):**
- **Flight controls**: Flaps, gear, throttle, pitch/roll/yaw inputs ✅ TESTED
- **COM/NAV frequencies**: Radio management
- **Autopilot commands**: Altitude, heading, airspeed selection
- **Real-time response**: Commands execute immediately in simulator
### 🏗️ **Architecture Overview**
```
Aerofly FS 4 ↔ AeroflyBridge.dll ↔ Multiple Interfaces ↔ External Apps
↓
[Shared Memory] ← Ultra-fast (local)
[TCP Server] ← Network/Python
[JSON API] ← Web/Mobile
```
**Data Flow:**
- **Reading**: Aerofly → DLL → Shared Memory/TCP → Applications
- **Writing**: Applications → TCP Commands → DLL → Aerofly
## 🧪 **TESTING RESULTS**
**✅ Shared Memory Test:**
- Access to flight data: Position, altitude, speeds, attitude
- Update frequency: ~60Hz
- Latency: <1ms
- Data integrity: 100% reliable
**✅ Command Control Test:**
- Flap control: **WORKING** - Visual movement confirmed in simulator
- Throttle control: **WORKING**
- Real-time response confirmed
## 🛠️ **Technical Implementation**
**Built using:**
- Official IPACS SDK (`tm_external_message.h`)
- Visual Studio 2022 compilation
- Thread-safe operations
- Multi-interface architecture
**Performance:**
- Zero impact on simulator FPS
- Concurrent client support
- Robust error handling
## 🎯 **POTENTIAL APPLICATIONS**
This bridge opens up incredible possibilities:
**🎮 Hardware Integration:**
- Force Feedback systems using G-force data
- Custom instrument panels
- Motion platform control
**📊 Navigation & Analysis:**
- XCSoar integration for gliding
- Flight data logging and analysis
- Real-time performance monitoring
**🌐 Remote & Web Applications:**
- Mobile apps for flight monitoring
- Web-based dashboards
- Multi-user training scenarios
**🤖 AI & Automation:**
- Machine learning flight data collection
- Automated flight testing
- Custom autopilot algorithms
## 🔧 **CURRENT WORK & NEXT STEPS**
**Phase 1 (Current):** ✅ Core functionality working
**Phase 2 (In Progress):**
- Fine-tuning variable mapping
- Python SDK development
- Thread cleanup optimization
**Phase 3 (Planned):**
- Complete Python SDK with examples
- C++ library for native applications
- Web API for browser-based apps
- Comprehensive documentation
## 🤝 **COMMUNITY COLLABORATION**
This project is being developed with community feedback in mind. We’re building:
- **Open architecture** for easy integration
- **Standard protocols** (JSON, shared memory)
- **Multi-language support** from day one
## 📋 **FOR DEVELOPERS**
If you’re interested in integration development, this bridge will provide:
- Direct access to all 285 simulator variables
- Real-time control capabilities
- Multiple interface options for different use cases
- Production-ready stability
## 🎊 **EXCITING PROGRESS**
We’ve successfully achieved **bidirectional control** - something that’s been a long-time goal for the Aerofly community. The ability to both read data AND control the simulator opens up entirely new possibilities for hardware integration, training applications, and community projects.
**Stay tuned for more updates!** We’ll be sharing the complete Python SDK and examples soon.
