Usage

IRfidReader rfidReader;

public override Task Initialize()
{
    Resolver.Log.Info("Initialize...");

    rfidReader = new IDxxLA(Device, Device.PlatformOS.GetSerialPortName("COM1"));

    // subscribe to event
    rfidReader.RfidRead += RfidReaderOnTagRead;

    // subscribe to IObservable
    rfidReader.Subscribe(new RfidObserver());

    return Task.CompletedTask;
}

public override Task Run()
{
    rfidReader.StartReading();

    return Task.CompletedTask;
}

private void RfidReaderOnTagRead(object sender, RfidReadResult e)
{
    if (e.Status == RfidValidationStatus.Ok)
    {
        Resolver.Log.Info($"From event - Tag value is {DebugInformation.Hexadecimal(e.RfidTag)}");
        return;
    }

    Resolver.Log.Error($"From event - Error {e.Status}");
}

private class RfidObserver : IObserver<byte[]>
{
    public void OnCompleted()
    {
        Resolver.Log.Info("From IObserver - RfidReader has terminated, no more events will be emitted.");
    }

    public void OnError(Exception error)
    {
        Resolver.Log.Error($"From IObserver - {error}");
    }

    public void OnNext(byte[] value)
    {
        Resolver.Log.Info($"From IObserver - Tag value is {DebugInformation.Hexadecimal(value)}");
    }
}
