什么设置控制enddevice加入网络后周期性的发送 data request 帧？
你可以在f8wConfig.cfg文件中找到
/* The number of milliseconds to wait between data request polls to the coordinator. */-DPOLL_RATE=1000
然后你可以看一下这个定义在哪里使用了。
enddevice采用POLL方式，就是周期性苏醒，然后查询父节点是否有数据。可以看到Enddevice 在IAR的project options->c/c++compiler ->preprocessor->defined symbols中 定义了NWK_AUTO_POLL。然后POLL_RATE决定了苏醒的时间间隔，越长功耗越低，越短功耗越高
