Deep Sync Relay Server

The Deep Sync Relay is a C#/.NET 7 application designed to relay and manage real-time biometric data between wearable devices and a client application over TCP. It is receiving data from multiple wearables, and forwards it to a client app.

Features

• TCP Communication: Listens to incoming data from wearables and the client app on configurable ports.
• User Management: Tracks connected users (wearables), assigns unique IDs, and manages timeouts.
• Data Relay: Receives, and forwards heart rate and SpO2 data.
• Command Handling: Supports commands from the client app to wearables (e.g., assigning new IDs).
• Debug Mode: Simulates multiple users and generates test data for development and testing (-d).
• Threaded Architecture: Uses threads and async tasks for efficient, concurrent data handling.

Architecture Overview

• Wearables connect to the server via TCP, sending JSON-formatted biometric data.
• Client Application connects via TCP to receive user data and send commands.
• The server maintains a concurrent dictionary of users and relays messages as needed.

Usage

Prerequisites

• .NET 7 SDK
• Visual Studio 2022 or later

Running the Server

1. Build the project in Visual Studio 2022.
2. Run the server from the command line or within Visual Studio.

Command-Line Arguments

• -d
  Enable debug mode (generates test users and data).
• -ip <address>
  Set the TCP address for the client application (default: 192.168.101.223).

Example:

DeSyServer.exe -d -ip 192.168.19.203

TCP Ports

• Wearable to Server: 53397
• Server to Wearable: 53396
• App to Server: 43396
• Server to App: 43397

Data Format

All communication uses JSON. Example user data: { "userId": 1, "ip": "192.168.111.10", "heartRate": { "last": 75, "average": 72 }, "spO2": { "lastSpO2": 98.5, "averageSpO2": 98.0 }, "lastUpdate": "2025-11-25T12:34:56" }

Main Classes

• DeSyDataRelay: Main server logic, TCP handling, user management.
• UserData: Represents a user's biometric data and connection info.
• NewIdCmd, DeepSyncCmd: Command structures for communication.

Extending

• Add new sensor types by extending UserData and updating JSON handling.
• Adjust timeouts and port numbers as needed in DeSyDataRelay.
