终端设备收不到IEEE_addr_rsp消息

代码大致入下；

1、先注册ZDO_RegisterForZDOMsg(App_TaskID, IEEE_addr_rsp);

2、发送IEEE地址请求，ZDP_IEEEAddrReq(0, ZDP_ADDR_REQTYPE_EXTENDED, 0, 0);

3、在process event函数的ZDO_CB_MSG消息增加对IEEE_addr_rsp的处理代码。

测试发现如果不将-DRFD_RCVC_ALWAYS_ON=FALSE设置成TRUE，终端设备无法收到IEEE_addr_rsp消息。我在编译选项里面已经加入了NWK_AUTO_POLL选项，为什么还必须将-DRFD_RCVC_ALWAYS_ON=FALSE设置为TRUE呢？

哪位大神知道这是什么原因，是不是哪里的设置有问题呢？

你的POLL RATE设置成了多少？

您好，f8wConfig.cfg的配置入下：

/* The number of milliseconds to wait between data request polls to the coordinator. */
-DPOLL_RATE=1000

/* This is used after receiving a data indication to poll immediately
 * for queued messages...in milliseconds.
 */
-DQUEUED_POLL_RATE=100

/* This is used after receiving a data confirmation to poll immediately
 * for response messages...in milliseconds
 */
-DRESPONSE_POLL_RATE=100

/* 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

麻烦你帮我分析下是什么原因？我自己实在是不知道哪里没有设置对，谢谢。
