Arduino 与 Raspberry Pi 使用 nRF24L01p 进行通信
Communication between Arduino and Raspberry Pi using nRF24L01p
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 包作为模块的驱动程序。我的 arduino 正在发送一个 "Hello World" 字符串。在这种情况下，RPi 是接收器，程序只是检查它们的通信是否已建立。但我不能那样。是不是因为接收到数据的事件没有触发？或者是配置不正确。在此先感谢您的帮助。

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。接收端对应的通道收到数据后进行响应，采用响应包中的地址。接收通道对应的地址为发送端的发送通道地址，发送端默认使用通道0应答最多，所以应将发送端的通道0地址设置为发送通道地址。
接收最好用1-5通道，因为发送时会用0通道接收响应，发送前会把对方的一个接收通道的地址写入发送通道数据。

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。接收端对应的通道收到数据后进行响应，采用响应包中的地址。接收通道对应的地址为发送端的发送通道地址，发送端默认使用通道0应答最多，所以应将发送端的通道0地址设置为发送通道地址。
接收最好用1-5通道，因为发送时会用0通道接收响应，发送前会把对方的一个接收通道的地址写入发送通道数据。
