感谢回复，这个帖子过的时间有点久了，我现在有时间重新看这部分的内容之后，上面的json内容可能会有误解。我重新贴一下：

{
	"$schema":"file:\/\/\/BlueZ\/Mesh\/local_schema\/mesh.jsonschema",
	"meshName":"BT Mesh",
	"netKeys":[
		{
			"index":0,
			"keyRefresh":0
		}
	],
	"appKeys":[
		{
			"index":0,
			"boundNetKey":0
		},
		{
			"index":1,
			"boundNetKey":0
		}
	],
	"node":{
		"composition":{
			"cid":"0002",
			"pid":"0010",

				}
			]
		},
		"IVindex":5,

		"sequenceNumber":807
	}
      }

上面这一块是我上个回复的json内容(排版容易看点)。这个我看了一下确实是provisioner(树莓派(bluez))的数据。另外我用它作为provisioner添加了两个节点，node_1和node_2，它们的内容是下面的json：

{
	"$schema":"file:\/\/\/BlueZ\/Mesh\/schema\/mesh.jsonschema",
	"meshName":"BT Mesh",
	"netKeys":[

	],

					}
				]
			},
			"IVindex":5,
			"sequenceNumber":13
		},
		{

		"configuration":{
			"netKeys":[
				"0000"
			],
			"elements":[

				"models":[

	],
	"IVindex":5,
	"IVupdate":0
}

1. 从上面结果看下来的话provisioner确实既有configuration client也有configuration server了。
2. 我还想额外提一个问题，假设这里有两个灯设备，我的网关作为配置者(provisioner)也能够控制这两个灯。在不使用组播的前提下，我用单播控制两个灯，那在网关这边只需要在主元素里定义一个generic on-off client就够了吧？有没有必要在主元素定义一个generic on-off client控制灯A，在次元素A定义一个generic on-off client控制灯B？提这个问题的目的主要是想是否可以在client端这边只用主元素，不额外用次元素定义这么多client，毕竟控制端不会保存状态。

Wireless-Tech 你从哪里得出这样的判断？

在我第二个json里面有这一部分，贴出了配置者的单播地址是0x0077，我单独贴出来这一部分：

"provisioners":[
		{
			"provisionerName":"BT Mesh Provisioner",
			"unicastAddress":"0077",
			"allocatedUnicastRange":[
				{
					"lowAddress":"0100",
					"highAddress":"7fff"
				}
			]
		}
	],

对比我第一个json里面的元素，它的单播地址也是0x0077：

"elements":[
				{
					"elementIndex":0,
					"unicastAddress":"0077",
					"models":[
						{
						"modelId":"1001",
						"bind":[
							1
						]
						}
					]
				}
			]

这应该可以认为它是配置者的设置。

补充一下，网上用bluez测试mesh的资料太少了，所以我不怎么清楚从哪下手，为数不多的资料可能就是官方的一个pdf了https://www.bluetooth.com/wp-content/uploads/2020/04/Developer-Study-Guide-How-to-Deploy-BlueZ-on-a-Raspberry-Pi-Board-as-a-Bluetooth-Mesh-Provisioner.pdf有兴趣可以玩一下。
