nRF24l01基于STM32的一对二通信

九五凤凰

找了好多资料说nRF24l01最多可以是实现1对6的通信或者6对1 的通信，可是自己实践了一下，目前只做通了一对一的通信。现在想做1对2的通信（一发二收），查资料说<p style="z-index:187;position:absolute;padding-bottom:0px;widows:2;text-transform:none;background-color:#ffffff;text-indent:0px;margin:0px;padding-left:0px;width:339px;padding-right:0px;font:169px/169px 宋体, '655a4b84a0116c175f0e488f0020001', 宋体;white-space:nowrap;orphans:2;letter-spacing:normal;height:169px;color:#313d31;top:2546px;word-spacing:0px;padding-top:0px;left:1448px;-webkit-font-smoothing:antialiased;text-shadow:rgba(0, 0, 0, 0.00392157) 1px 1px 1px;-webkit-text-size-adjust:auto;-webkit-text-stroke-width:0px;" class="reader-word-layer reader-word-s1-5">对于</p>

对于0和1通道，接收端和发送端的地址是可以都写成5个字节的地址，当然可以两端是同样的地址，很容易就实现了通信；但是对于2、3、4、5通道，接收端的地址只有低字节可以设置，发送端的发送地址却是5个字节的。如何相同是个问题。对于通道1和2、3、4、5通道为什么在设置地址上不一样这点很疑惑，还有就是对于通道0和1可以设置相同的地址也很疑惑。如果相同的地址，接收端是如何判断到底是通道0还是通道1呢？

<br>个人觉得你最好去看下英文原版的数据手册，中文版基本都是删节版。他们说的6对1是指的6发1收。你说的1发2收我觉得不太可能，如果用到自动应答的话，一个发送机怎么去判定是哪个发来的应答信号呢

<br>那如果把自动应答去了，我发送的数据通过两块板子接收，我的两个接收板子都有屏，可以通过屏查看他们是否通信成功。我用的是IAR的开发环境，可以通过watch查看他们的寄存器的值，如果这样呢，你觉得一发二收还可行吗？

jiaozhu

接收机的接收地址设置成一样的话应该是可以的，发送机只管把数据发出去，到底有没有接收机在收它也不管了，到底有几个在收，它更是管不了，无应答的话也就是代表发送机与接收机之间没有沟通了。你可以试试，我也没弄过。

<br>我采用了另一种方式，让通道0采用自动应答，而通道1不自动应答，通过watch查看他们的寄存器的值。让两个从机先运行，然后再开主机，试了一下，成功了，\(^o^)/~谢谢你的帮助

<br>还有一种方式，自动应答的信号中是可以包含数据的，这样的话就是表面上是2发1收，但你可以通过自动应答数据包将数据返回去。你也可以研究研究，这个难度就大点了，但是就包含了应答信号，保障性大。
