器件型号：CC2652P Thread 中讨论的其他器件： SysConfig、 Z-stack
早上好。
我们将测试一些基于 CC2652P ZNP 协调器的拓扑架构、这些架构连接到一条直线型器件、这些器件由定制路由器和定制终端设备组合而成、每个都具有8个"智能插头"型端点、 用于轮询它们的计量/ONOFF 值并由 ONOFF 命令到达。
我们的应用需要至少30个器件的一些线路、这些器件的间距约为20米、从而最大程度地减少了协调器的数量。 低于这些数字的任何数量的器件都不能证明 Zigbee 不适合使用传统的大 Wi-Fi 网络。
固件是 zr_genericapp 和 zed_genericapp 的变体、手动添加工作端点、群集和属性。
1 -我们首先尝试将一系列20台路由器直接连接到一条直线上，标准间约为20/30米
结果并不是很有希望：首次尝试到第10个节点时、设备的现场配对一直在进行、然后面谈在需要6、7次尝试才能成功结束之前逐渐失败。 然后、轮询器件对于第一个节点运行良好、然后在轮询第12 /第13个及以上器件时导致超时。 因此、我们可以减去最大跳数大约为10 (正如 Ryan 几次之前告诉我的那样)。 是否可以以任何方式递增此数字？ 我尝试对默认/ti_zstack_config.h 和 Stack/nwk_globals.h 中的一些旋钮进行调优、但没有区别：

2 -我们将路由器数量限制为8台，从而获得以下拓扑：
然后、我创建了一个脚本来轮询器件的端点(使用 Zigbee2Mqtt API)并测量经过的时间、首先仅轮询每个器件的单个端点(2个集群、计量和 ONOFF)、然后针对8个器件中的每个器件的所有8个端点(智能插头)。 未发生超时。 以下是日志：

因此、向中央路由器线路添加终端设备似乎可以减少跳数并使网络更大、但我们的应用无法接受这些数量级的延迟。
4 -我们还在实验室中将先前测试中的16个器件(8个路由器+ 8个终端设备)带到了内部、保留了绑定和配对、并重复了测量测试
