Why JN5169 IoT gateway will form a new ZigBee network even if "preserve the EEPROM"?

Hello,

I want to update the firmware of JN5169 IoT gateway. When burning the image into JN5169, I chose "preserve the EEPROM", but why the gateway still create a new ZigBee network with a new PAN ID? And then the former 64 children nodes are still connecting to the former network?

What is the manual to upgrate the central node of the ZigBee network?

Tks so much!

Hi,

你的zigbee网络是由哪些设备组成的?

Have a great day,

Hi,

One ZigBee IoT gateway with JN-SW-4168

64 Dimmable Lights with JN-AN-1189

Hi,

你只有一个co-ordinator,然后64个device,你co-ordinator建立完网络以后,便可以认为是路由器了。你co-ordinator断电或者断联以后,想要重连的话,必须存在一个网络,但是一旦你断开以后,64个设备失去了路由器,zigbee网络就已经不存在了。device没法自己维持网络,所以co-ordinator找不到网络只能新建一个新网络。所以至少应该再有一个路由器。co-ordinator建立网络以后,一个路由连上去,然后这个路由挂64个设备,如果你co-ordinator断电了或者其他情况断联,那么路由还能维持网络存在。

Have a great day,
TIC

Hi,

The dimmable lights work as Routers, the ZigBee network still exist even if the gateway powers down.

The problem is why the gateway forms a new PAN, instead of rejoining the network.

The gateway formed a new PAN with another channel because the lights as Router works in the target channel?

What is the correct manual to exchange the gateway?

What if the gateway works improperly? How to change it?

再确认一下,我看了JN-UG-3091这个文档,里面说ZLL是没有co-ordinator的,他们创建网络的方式是由initiator和一个router构建的(6.4.1),initiator一般是一个终端设备并且没有路由功能的设备,initiator发起扫描,来跟一个路由器通信,然后控制路由器来开启网络。所以你的网关是initiator?你的其他设备都是router?如果这样,你的问题就是initiator更新以后会创建新网络?查看6.4.2节,一个节点的加入是需要initiator的,由initiator扫描到周边节点,然后让其连接,所以一旦网关initiator离开以后,再次上线,它可能没办法加入网络,因为没有initiator处理新加入的节点。
