RtlSdrManager 0.2.0

Installation

RTL-SDR Manager Library is available via NuGet package manager. You can easily install it via the usual ways.

# dotnet CLI
dotnet add package RtlSdrManager

# nuget CLI
nuget install RtlSdrManager

Usage

Handling RTL-SDR device:

// Initialize the Manager instance.
var manager = RtlSdrDeviceManager.Instance;

// Open a managed device and set some parameters.
manager.OpenManagedDevice(0, "my-rtl-sdr");
manager["my-rtl-sdr"].CenterFrequency = new Frequency {MHz = 1090};
manager["my-rtl-sdr"].SampleRate = new Frequency {MHz = 2};
manager["my-rtl-sdr"].TunerGainMode = TunerGainModes.AGC;
manager["my-rtl-sdr"].AGCMode = AGCModes.Enabled;
manager["my-rtl-sdr"].MaxAsyncBufferSize = 512 * 1024;
manager["my-rtl-sdr"].DropSamplesOnFullBuffer = true;
manager["my-rtl-sdr"].ResetDeviceBuffer();

Asynchronous sample reading from the device:

// Start asynchronous sample reading.
manager["my-rtl-sdr"].StartReadSamplesAsync();

Read samples from the buffer:

// Dequeue from the buffer.
if (!manager["my-rtl-sdr"].AsyncBuffer.TryDequeue(out var data))
{
    Thread.Sleep(100);
    continue;
}

// Use the sample
Console.WriteLine(data);
