Installation

dotnet add package CSLibrary2026

Or add to your .csproj:

<PackageReference Include="CSLibrary2026" Version="1.0.0-beta.1" />

Quick Start

1. Connect to a Reader

Bluetooth LE (CS108, CS468, CS710S, CS203XL)

using CSLibrary;

// Create the reader instance
var reader = new HighLevelInterface();

// Discover BLE devices
var deviceFinder = new DeviceFinder();
deviceFinder.OnDeviceFound += (sender, device) =>
{
    Console.WriteLine($"Found: {device.Name}");
};
await deviceFinder.StartScanAsync();

// Connect to a BLE reader
await reader.ConnectAsync(adapter, device, MODEL.CS108);

TCP/IP (CS203XL — Network API)

using CSLibrary;

// Create the reader instance
var reader = new HighLevelInterface();

// Connect via TCP/IP (CS203XL Network API)
await reader.ConnectAsync("192.168.1.100", 2000);

2. Subscribe to Events

// RFID tag inventory callback
reader.rfid.OnAsyncCallback += (sender, e) =>
{
    if (e.type == Constants.CallbackType.TAG_RANGING)
    {
        Console.WriteLine($"EPC: {e.info.epc}");
    }
};

// Reader state change callback
reader.OnReaderStateChanged += (sender, e) =>
{
    Console.WriteLine($"State: {e.state}");
};

3. Start Inventory

// Set power level (0–3000 = 0–30.00 dBm)
reader.rfid.SetPowerLevel(3000);

// Start inventory
reader.rfid.StartOperation(RFIDReader.Operation.TAG_RANGING);

// Stop after some time
reader.rfid.StopOperation();

API Overview

Connection

Method	Description
ConnectAsync(IAdapter, IDevice, MODEL)	Connect to a BLE reader
ConnectAsync(string ipAddress, int port)	Connect to a TCP/IP reader
DisconnectAsync()	Disconnect from the reader

RFID Operations

Start operations:

reader.rfid.StartOperation(Operation.TAG_RANGING);       // Inventory
reader.rfid.StartOperation(Operation.TAG_READ);           // Read tags
reader.rfid.StartOperation(Operation.TAG_READ_TID);       // Read TID bank
reader.rfid.StartOperation(Operation.TAG_READ_USER);      // Read USER bank
reader.rfid.StartOperation(Operation.TAG_WRITE);         // Write tags
reader.rfid.StartOperation(Operation.TAG_LOCK);           // Lock tag
reader.rfid.StartOperation(Operation.TAG_KILL);           // Kill tag
reader.rfid.StopOperation();                             // Stop continuous operation

Power & Frequency:

reader.rfid.SetPowerLevel(uint pwrlevel);           // Set power (0–3000)
reader.rfid.GetActiveMaxPowerLevel();               // Get max power
reader.rfid.SetCurrentLinkProfile(uint profile);    // Set link profile
reader.rfid.SetCountry(string countryName);         // Set country frequency
reader.rfid.SetCountry(string countryName, int ch);// Set country + fixed channel

Singulation Algorithms:

reader.rfid.SetCurrentSingulationAlgorithm(SingulationAlgorithm.FIXEDQ);
reader.rfid.SetFixedQParms(FixedQParms parms);
reader.rfid.SetDynamicQParms(DynamicQParms parms);
reader.rfid.SetTagGroup(TagGroup tagGroup);
reader.rfid.SetPostMatchCriteria(SingulationCriterion[] criteria);

Callback Events:

• reader.rfid.OnAsyncCallback — Inventory / tag data (CallbackType.TAG_RANGING, TAG_SEARCHING)
• reader.rfid.OnAccessCompleted — Read/write/lock result
• reader.OnReaderStateChanged — RFID reader state

Battery & Notifications

reader.GetCurrentBatteryLevel();              // Get battery level
reader.ClearEventHandler();                   // Clear all callback events

reader.notification.OnVoltageEvent += ...     // Battery level changes
reader.notification.OnKeyEvent += ...         // Hotkey presses

Barcode Scanner

reader.barcode.OnCapturedNotify += (sender, e) => Console.WriteLine($"Barcode: {e.Barcode}");
reader.barcode.Start();
reader.barcode.Stop();

Events:

• OnCapturedNotify — Captured barcode data
• OnStateChanged — Scanner state

Architecture

CSLibrary2026 uses a transport abstraction layer (ITransport) to support both Bluetooth LE and TCP/IP connections:

HighLevelInterface
├── rfid          — RFID operations (inventory, read/write, lock/kill)
├── barcode       — Barcode scanning
├── notification  — Battery, key events
└── _transport    — ITransport (BLETransport or TCPTransport)

ITransport
├── ConnectAsync()  — Connect via BLE or TCP
├── SendAsync()     — Send command data
├── Disconnect()    — Close connection
└── SetReceiveCallback() — Handle incoming data
