自己测试了下，进入睡眠后。利用片选脚进行唤醒后，如果不重新配置寄存器的话通信就不正常。

但是查看了官方例程并没有配置寄存器。

直接使用官方例程测试下，是否唤醒后能正常工作

你好，能给一下官方的测试CC113L和CC1150的通信的例程吗？

你好，我现在试着让系统进入睡眠模式，运行的是这两条指令：

CC1101_SET_CSN_HIGH( );
CC1101_Write_Cmd(CC1101_SPWD)；

但是没有明显的效果，请问你是怎么进入睡眠模式的？最好能把程序贴出来，先谢谢你了。

你可以参考simpliciTI代码中关于sleep和wakeup的操作

if(mrfiRadioState != MRFI_RADIO_STATE_OFF)

MRFI_RxIdle();

mrfiSpiCmdStrobe( SPWD );

/* Our new state is OFF */
mrfiRadioState = MRFI_RADIO_STATE_OFF;
