z-stack重新搜索网络rejoin的时间间隔

z-stack重新搜索网络rejoin的时间间隔可以重那些地方修改，我想让复位时，LED闪烁的亮度高点

uint16 zgRejoinPollRate = REJOIN_POLL_RATE;

/* This is used as an alternate response poll rate only for rejoin request.
* This rate is determined by the response time of the parent that the device
* is trying to join.
*/
-DREJOIN_POLL_RATE=440

这个变量定义在f8wConfig.cfg文件中
