Arduino Connection Pi Connection
我想使用nRF24L01p模块在Arduino和Raspberry Pi（运行win10 iot）之间建立通信。我使用“ IS_nRF24L01p” nuget软件包作为模块的驱动程序。我的arduino正在发送“ Hello World”字符串。在这种情况下，RPi是接收器，并且该程序仅用于检查其通信是否建立。但是我不能。是否是因为未触发接收数据的事件？还是配置不正确。预先感谢您的帮助。

{
Serial.begin(9600);
radio.begin();
radio.setRetries(15, 15);
radio.setChannel(10);
radio.openWritingPipe(rxAddr);
radio.stopListening();
}
void loop()
{
const char text[] = "Hello World";
radio.write(&text, sizeof(text));
delay(1000);
Serial.println("Sent."); // TO check whether the data is sent.

从您提供的代码中，我找不到用于注册nRf24_OnDataReceived事件处理程序的行。请尝试添加类似于以下代码的处理程序。
private void setup()
{
System.Diagnostics.Debug.WriteLine("Initialize MTPNordic");
nRf24.InitNordicSPI(new SpiConnectionSettings(0), 3000000, 12, 13);
nRf24.OnDataReceived += new nRF24L01P.OnDataReceivedEventHandler(nRf24_OnDataReceived);
RFConfiguration();
}
抱歉，我没有nRF24L01p模块来测试此问题。请随时告诉我是否对您有帮助。

}
发送方发送数据时，数据包中的地址采用“ TX_ADD”的地址。该地址是接收端的几个接收通道（6个通道）之一。接收到数据后，接收端对应的通道会做出响应，并采用响应报文中的地址。接收通道对应的地址为发送端的发送通道地址，发送端使用通道0最多回答默认值，因此应将发送端的通道0地址设置为发送通道地址。
最好使用1-5个通道进行接收，因为发送时将使用0个通道来接收响应，并且在发送数据之前将对方的接收通道的地址写入发送通道。
