cc430f5137接收状态频频死机
问题 描述： 使用cc430f5137一个作为发送端，一个作为接收端。发送端能正常工作，接收端经常死机，一般半小时左右就会死。
用的是TI的代码，只要设置ReceiveOn();就会死机，连串口都不通，如果不设置为接收态就没事。
以下为部分代码，请大师解答，谢谢！

同样的代码在TI开发板上会死机吗？
谢谢，开发板也会死的，用得是利尔达的收发模块，利尔达的代码是依靠看门狗复位处理死机的，不可取。
我在网上查过相关信息，觉得不少人被这种情况坑过，应该会有解决办法吧？

你好这个问题是怎么处理的呀 ，我最近才做了一个板子 ，把程序烧写进去，一开始可以通信，过半个小时候之后，就通信不上了，反应到电流上的变化时 ，正常情况下总电流18mA ，过半个小时候之后 电流就下降到2mA，且通信不上
