CC1101 OOK 异步直通模式

现在的问题就是用频谱仪能检测到发射信号，但是用专门接收OOK信号的接收模块不能看到高低电平的变化，用其他OOK的遥控器能够看到高低电平规律的变化

你可以先用FIFO模式，看是否通上。然后使用异步模式，这里可能的问题是你的PA_TABLE的设置问题。

请问PA_TABLE的设置为什么会影响接收呢？

您好，刚才我测试过了，使用您的OOK的FIFO配置代码，还是不能接收，PA表我已经全部初始化为0xC0了

• 
  
• 第一个要是0
  

您好，上面的配置可以使用FIFO发送和接收了，改成OOK调制方式，能够通过GIO0发射出去，但是切换为射频输入时，使用GIO2不能接收信号，看不到信号有输出，GIO2的配置为0x0D,请问是什么原因呢？望解答

您好，请问cc1101在FSK模式下，可以不用接收前导码和帧同步码吗？我把MDMCFG2=0x03(能接收)改成MDMCFG2=0x00(不能接收)后就无法通信了，不知道是什么原因，求TI的大神帮忙解决下，非常感谢
