What Contains

In NRF24L01.cs file

/// <summary>
/// Initialize
/// </summary>
public async Task InitializeAsync();
/// <summary>
/// Send
/// </summary>
/// <param name="data">Data</param>
public async void Send(byte[] data);
/// <summary>
/// Receive
/// </summary>
/// <param name="length">Packet Size</param>
/// <returns>Data</returns>
public byte[] Receive(byte length);

How to Use

• First, you need to create a NRF24L01 object. After that you should call InitializeAsync() to initialize.

// Create and Initialize
// CSN Pin, CE Pin, IRO Pin, SPI Friendly Name, Receive Packet Size
NRF24L01 sender = new NRF24L01(0, 23, 24, "SPI0", 12);
NRF24L01 receiver = new NRF24L01(0, 5, 6, "SPI1", 12);
await sender.InitializeAsync();
await receiver.InitializeAsync();

• Secondly:

sender.Send(Encoding.UTF8.GetBytes("ZhangGaoxing"));
receiver.ReceivedData += Receiver_ReceivedData;
private void Receiver_ReceivedData(object sender, ReceivedDataEventArgs e)
{    
    var raw = e.Data.Skip(1).ToArray();
    var res = Encoding.UTF8.GetString(raw);
    Debug.Write("Received Raw Data : ");
    foreach (var item in raw)
    {
        Debug.Write($"{item} ");
    }
    Debug.WriteLine("");
    Debug.WriteLine($"Received Data : {res}");
}

• If you want to close the sensor, call Dispose().

sender.Dispose();
receiver.Dispose();
