TI中文支持网我想实现路由设备判断协调器是否在线的功能，所以在路由设备发送数据给协调器的时候，在AF_DataRequest函数中或上AF_ACK_REQUEST，然后抓包发现协调器有APS返回。
我在路由设备的AF_DATA_CONFIRM_CMD，中对status进行判断：
afDataConfirm = (afDataConfirm_t *)MSGpkt;
sentEP = afDataConfirm->endpoint;
sentStatus = afDataConfirm->hdr.status;
sentTransID = afDataConfirm->transID;
(void)sentEP;
(void)sentTransID;
if ( sentStatus != ZSuccess )
{}
发现，发送成功的时候sentStatus 为0x00。失败的时候，无论是否开启AF_ACK_REQUEST，收到的都是ZMacNoACK 0xe9。请问为什么没收到ZApsNoAck？
我怎样才能区分开是mac ack还是aps ack？

AF_DATA_CONFIRM
This command is sent by the device to the user after it receives an AF_DATA_REQUEST. For each AF_DATA_REQUEST, a AF_DATA_CONFIRM is always returned. If APS acknowledgement was used for the AF_DATA_REQUEST, the confirm carries the status of whether the APS acknowledgement was received or not (ZApsNoAck – 0xb7). If APS acknowledgement was not used, then the confirm carries the status of whether the MAC acknowledgement (“next hop” acknowledgment) was received or not (ZMacNoACK – 0xe9). This also applies to packets that are sent using AF_DATA_REQUEST_EXT and AF_DATA_STORE.
For APS fragmented packets, the value of the configuration item ZCD_NV_APSF_WINDOW_SIZE determines when an AF_DATA_CONFIRM that carries the status of the APS acknowledgement is received.

感谢回复！！
我在发送函数中已经或上了AF_ACK_REQUEST，但是接收到的还是ZMacNoACK ，没有ZApsNoAck。
还有就是AF_DATA_REQUEST和AF_ACK_REQUEST有什么区别？AF_DATA_REQUEST要怎么样使用？

ZApsNoAck我的路由设备发送心跳包给协调器，在发送函数在AF_DataRequest函数中或上AF_ACK_REQUEST。
抓包能够看到协调器回复的APS：
当我把协调器断电的时候，我在路由设备的AF_DATA_CONFIRM_CMD，中对status进行判断：
afDataConfirm = (afDataConfirm_t *)MSGpkt;sentEP = afDataConfirm->endpoint;sentStatus = afDataConfirm->hdr.status;sentTransID = afDataConfirm->transID;(void)sentEP;(void)sentTransID;if ( sentStatus != ZSuccess )
{}
只能接收到ZMacNoACK ，却接收不到ZApsNoAck。
是不是还有哪里没配置好，或是在AF_DATA_CONFIRM_CMD中没处理好？
