CC2541 偶尔停止广播只有重新上电才重新开始广播

协议栈是1.32的，晶振都是用的20ppm的，模式是一般广播模式，按说会一直周期广播啊，但是偶尔会停止广播。求解

采用低功耗工作模式不？

代码中的搜索如下变量，默认基本是0,则广播30.72秒后会停止

// By setting this to zero, the device will go into the waiting state after
// being discoverable for 30.72 second, and will not being advertising again
// until the enabler is set back to TRUE

uint16 gapRole_AdvertOffTime = 0;
