nrf2401的配置在头文件中，若要修改，仅需改一下头文件中的相关值即可。在第一次配置操作结束后，

只有最后两个字节的命令字可以被更改，前16个字节的修改无效，如果需要修改前16个字节的命令字（如通道接收地址，接收数据长度等），

则需要掉电（PWR_UP置低）后重新上电（PWR_UP置高），才能对芯片进行彻底初始化操作。-nrf2401 configuration in the header file, to change, just change it in the header file associated value. In the first configuration operation is completed,

Only the last two bytes of the command word can be changed, change the first 16 bytes is invalid, if the need to modify the first 16 bytes of the command word (such as channel receiver address, the received data length, etc.)

You need to power down (PWR_UP set low) after re-power (PWR_UP set high), in order to complete the initialization of the chip.
