终端设备刚上电的时候可以收到数据，差不多30秒后就收不到数据了；
终端设置如下：
/****************************************
* The following are for End Devices only
***************************************/
-DRFD_RCVC_ALWAYS_ON=FALSE//TRUE
/* The number of milliseconds to wait between data request polls to the coordinator. */
-DPOLL_RATE=2000
/* This is used after receiving a data indica
tion to poll immediately
* for queued messages...in milliseconds.
*/
-DQUEUED_POLL_RATE=100
