The NWK route record command records the route along the way, which results in a route
record indication at the gateway. Now, the gateway knows the route back to node “ E. ”
A → B → C → D → E
When the gateway transmits data to node “ E, ” it will indicate a source route in the data
request. As usual, ZigBee specifies the exact over-the-air form of a source routed data
request. A bit in the NWK frame control field indicates the packet is source-routed.
The term “ relay ” merely refers to the intermediate nodes between the gateway and the
destination node (see Figure A.2). They are in the same order as recorded with the route
record command, and the index just indicates the “ next-hop. ”
我的设备拓扑A → B → C
A:协调器
B:0xF584
C:0x41F9
使能many to one，并且有route record后，发送数据时为何不带source route？该如何使用呢
附件为抓到的数据包，···· ·0·· ···· ···· = Source Route Included: [0x0] No
我这里解析你的抓包，route record是 B->A发送的，并不是C->B->A的。
并且，该route record包中是有source route的，如图
