Hi all

there are 3 ZR and 1ZED in the network。

ZR1 : 0x7450

ZR2 : 0x45b1

ZR3 : 0x96B6

ZED : 0x575d

when the ZR had not forward the msg to ZED , i found that it seems the ZC have not update the link info of device.

i saw that ZC send the msg to ZR3 , and ZR3 have not forward it to ZED.

But ZED send to msg to ZC via ZR2, and ZC could revice it.

there is log :zrg.rar

1990 : ZED send the msg to ZC via ZR2 , And ZC coud get it

It seems that ZC doesn't aware ZED switch parent node from ZR3 (0x96B6) to ZR2(0x4B51) before packet number 6589. After that, coordinator fixes its routing table and can deliver message with correct routing path.

how long did the ZC update the routing path？

The ZED always do polling to ZR2 from the beginning of your sniffer log. Turn off ZR3 make ZC know ZED is not child node of ZR3 anymore and ZC does routing path update.

so my question is why ZED poll the ZR2，and ZC didn't aware it and also send the msg to ZR3。
anyway ，how long does ZC will aware of this new routing path if i have not power off the ZR3？

In general, ZC should send route request when it cannot send message to ZED. Your case might be a bug of Z-Stack.

i saw there is a lot of Router request and i wait for more than 10 minutes 。

but i have saw ZC have aware of this new routing path， it always sends the msg via ZR3 ， although ZED have already sends something via ZR2 to ZC。。。

BR!

I saw that too so I think this is bug of Z-Stack.
