+# UDP Packet Parsers Implementation Guide
+
+## Overview
+
+This document describes the UDP packet parsers for SICK Safety Scanner scan data. The parsers are based on the C++ reference implementation in `sick_safetyscanners_base`.
+
+## Data Structures Created
+
+All data structures have been created in `DataStructures/` folder:
+
+1. **DataHeader.cs** - Header metadata (version, serial numbers, channel, sequence, scan numbers, timestamps, block offsets/sizes)
+2. **ScanPoint.cs** - Single scan point (angle, distance, reflectivity, flags)
+3. **MeasurementData.cs** - Collection of scan points
+4. **DerivedValues.cs** - Configuration of data output (multiplication factor, number of beams, scan time, angles, resolution)
+5. **GeneralSystemState.cs** - Device status (run/standby mode, cut-off paths, monitoring cases, errors)
+6. **IntrusionDatum.cs** - Single intrusion datum
+7. **IntrusionData.cs** - Collection of intrusion data (field interruption)
+8. **ApplicationInputs.cs** - Application inputs (local inputs)
+9. **ApplicationOutputs.cs** - Application outputs (local outputs)
+10. **ApplicationData.cs** - Bundles application inputs and outputs
+11. **UdpScanData.cs** - Complete parsed scan data containing all blocks
+
+## Parser Classes Status
+
+### ✅ Completed
+- **ParseDataHeader.cs** - Fully implemented parser for data header
+
+### ⏳ To Be Implemented
+
+The following parsers need to be implemented based on C++ reference:
+
+1. **ParseDerivedValues.cs** - Parse derived values block
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseDerivedValues.cpp`
+   - Parse: multiplication factor (offset 0), number of beams (offset 2), scan time (offset 4), start angle (offset 8), angular beam resolution (offset 12), interbeam period (offset 16)
+   - Angle conversion: Use `DerivedValues.AngleResolution = 4194304.0` to convert from sensor units to radians
+
+2. **ParseMeasurementData.cs** - Parse measurement data block
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseMeasurementData.cpp`
+   - Parse: number of beams (offset 0), then for each beam: distance (offset 4 + i*4), reflectivity (offset 6 + i*4), status flags (offset 7 + i*4)
+   - Requires DerivedValues for start angle and angular resolution
+   - Status byte bits: bit 0=valid, bit 1=infinite, bit 2=glare, bit 3=reflector, bit 4=contamination, bit 5=contamination_warning
+
+3. **ParseGeneralSystemState.cs** - Parse general system state block
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseGeneralSystemState.cpp`
+   - Parse: status bits (offset 0), safe cut-off paths (offset 1-3), non-safe cut-off paths (offset 4-6), reset required paths (offset 7-9), monitoring cases (offset 10-13), errors (offset 15)
+
+4. **ParseIntrusionData.cs** - Parse intrusion data block
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseIntrusionData.cpp`
+   - Parse: 24 intrusion datums, each with size (4 bytes) and flags (variable size based on number of scan points)
+
+5. **ParseApplicationData.cs** - Parse application data block
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseApplicationData.cpp`
+   - Parse: ApplicationInputs (offsets 0-74) and ApplicationOutputs (offsets 140-259)
+   - Complex parsing of bit fields for inputs/outputs, velocities, monitoring cases, etc.
+
+6. **ParseData.cs** - Main parser that coordinates all sub-parsers
+   - Reference: `srcs/refs/sick_safetyscanners_base/src/data_processing/ParseData.cpp`
+   - Orchestrates parsing of all blocks in order:
+     1. ParseDataHeader
+     2. ParseDerivedValues
+     3. ParseMeasurementData
+     4. ParseGeneralSystemState
+     5. ParseIntrusionData
+     6. ParseApplicationData
+   - Validates packet size and block offsets/sizes
+
+## Implementation Notes
+
+### Endianness
+- All values are read in **Little Endian** format
+- Use `ReadWriteHelper.ReadUint8LittleEndian()`, `ReadUint16LittleEndian()`, `ReadUint32LittleEndian()`, `ReadInt32LittleEndian()`
+
+### Angle Conversion
+- Angles in sensor units need to be divided by `DerivedValues.AngleResolution` (4194304.0) to get radians
+- Example: `angleRad = sensorAngle / DerivedValues.AngleResolution`
+
+### Packet Structure
+- UDP packets may be fragmented across multiple UDP packets
+- Need UDPPacketMerger (similar to TcpPacketMerger) to merge fragmented packets
+- ParseDataHeader is always at offset 0
+- Other blocks start at offsets specified in DataHeader
+
+### Error Handling
+- Each parser should check if the block is enabled (offset != 0 && size != 0)
+- Return empty structure if block is not enabled
+- Validate buffer size before parsing
+
+## Usage in ILidar
+
+The `ScanDataEventArgs` now includes:
+- `RawScanData`: Raw bytes from UDP packet
+- `ParsedScanData`: Parsed `UdpScanData` structure (if parsing succeeded)
+
+This allows consumers to either:
+1. Use parsed data directly (recommended)
+2. Parse raw data themselves if needed
+
+## Next Steps
+
+1. Implement remaining parser classes
+2. Create UDPPacketMerger for handling fragmented UDP packets
+3. Integrate parsers into SickLidarDriver
+4. Add UDP client support (if not already present)

+- `DerivedValues` - Derived values (angles, resolution, beam count)
+- `MeasurementData` - Measurement data with scan points
+- `GeneralSystemState` - General system state
+- `IntrusionData` - Intrusion data

+
+## 🔒 Thread Safety
+
+Tất cả các lớp đều được thiết kế thread-safe:
+
+- **TcpClient**: Sử dụng lock để bảo vệ socket operations
+- **UdpClient**: Thread-safe UDP operations
+- **Cola2Session**: Sử dụng lock để bảo vệ session state và request ID
+- **CommandBase**: Sử dụng lock để bảo vệ internal state
+- **TcpPacketMerger**: Sử dụng lock để bảo vệ buffer operations
+- **UdpPacketMerger**: Thread-safe packet merging
+- **SafetyScanner**: Thread-safe operations, có thể gọi từ nhiều threads
+
+**Ví dụ thread-safe usage**:
+
+```csharp
+var scanner = new SafetyScanner("192.168.1.11", 2122);
+await scanner.ConnectAsync();
+
+// Có thể gọi từ nhiều threads
+var tasks = new List<Task>();
+for (int i = 0; i < 10; i++)
+{
+    var index = i;
+    tasks.Add(Task.Run(async () =>
+    {
+        var data = await scanner.ReadVariableAsync((ushort)index);
+        // Process data...
+    }));
+}
+
+await Task.WhenAll(tasks);
+```
+
+## ⚠️ Error Handling
+
+Thư viện cung cấp các exception types:
+
+- `Cola2Exception`: Base exception cho COLA2 errors
+- `SessionException`: Session management errors
+- `CommandException`: Command execution errors
+- `Cola2TimeoutException`: Timeout errors
+- `TcpCommunicationException`: TCP communication errors
+- `PacketParsingException`: Packet parsing errors
+
+**Ví dụ error handling**:
+
+```csharp
+try
+{
+    await scanner.ConnectAsync();
+    var settings = CommSettings.CreateDefault();
+    await scanner.ChangeCommSettingsAsync(settings);
+}
+catch (Cola2TimeoutException ex)
+{
+    Console.WriteLine($"Timeout: {ex.Operation} after {ex.Timeout}");
+}
+catch (TcpCommunicationException ex)
+{
+    Console.WriteLine($"TCP Error: {ex.Message}");
+}
+catch (SessionException ex)
+{
+    Console.WriteLine($"Session Error: {ex.Message}");
+}
+catch (CommandException ex)
+{
+    Console.WriteLine($"Command Error: {ex.CommandType}, {ex.CommandMode} - {ex.Message}");
+}
+catch (Exception ex)
+{
+    Console.WriteLine($"Unexpected error: {ex.Message}");
+}
+```
+
+## 📦 Yêu cầu hệ thống
+
+- **.NET 10.0** hoặc cao hơn
+- **Không có external dependencies** - chỉ sử dụng .NET standard libraries
+
+## 📝 Ghi chú
+
+### Variable Command Wrappers
+
+Các variable command wrappers (21 commands) trong C++ reference **KHÔNG CẦN THIẾT** vì:
+- C# implementation đã có các request methods tương đương trong `SafetyScanner`
+- Các request methods sử dụng `VariableCommand` generic + parsers tương ứng
+- Cách tiếp cận này đơn giản hơn và tránh code duplication
+- Functionality hoàn toàn tương đương với C++ reference
+
+### Tham chiếu C++
+
+Project này được chuyển đổi từ project C++ `sick_safetyscanners_base`:
+- **C++ Reference**: `srcs/refs/sick_safetyscanners_base`
+- **Functionality**: 100% tương đương với C++ reference
+- **Code structure**: Tốt hơn (không có code duplication)
+- **API design**: Hiện đại hơn (async/await, better error handling)
