nrf24l01在stm32f103中如何实现一发多收

meteor

希望哪位有心人帮忙解答nrf24l01在stm32f103中如何实现一发多收（由一个nrf24l01相同发送数据给多个nrf24l01）

正点原子

一个设置发送模式，其他都设置为接受模式，就可以实现一发多收

<br>那原子个，发送端的自动应答不会有影响吗？

<br>---------------------------------
<br>你可以关闭自动应答。

每个接收的无线模块设置为不同的频道，发送端要给哪个接收端发送时在主函数更改对应频道就可以，也可以设置为不同的地址

<br>如何设置其他通道的收发，我使用0通道可以接收数据，但是用其他通道就接收不到数据，而且发送端也一直显示状态是发送数据。

<br>有许多问题
<br>1.为什么在发送函数中使用通道0（0x01），接收端就可以接收数据，而使用通道1(0x02)却不可以?
<br>2.当将使能通道的应答模式和使能通道的接收地址中的0x02设置0x03，接收端又可以接收数据，其实应该还是通道0接收的数据
<br>3.当接收端接收不到数据时，为什么发送端接收到应答，显示发送数据而不是发送失败，
