Procedure to Change Coordinator Zigbee Channel

zigbee1 — Mon, 24 May 2021 12:03:28 GMT

I'm currently trying to understand how to get the coordinator able to change from one zigbee chanel to an other one.

JN-AN-1247-Zigbee-3-0-ControlBridge and Jn5189

My investigations are on the usage of ZPS_eAplZdpMgmtNwkUpdateRequest() which if I well understood is an implementation of the ZDP Mgmt_NWK_Update_req (cluster 0x0038) specifications.

While I see the controler moving to the channel specified in the call, I do not see any announcement prior to this change to inform ALL devices (and especially ZR) of such change.

The end result, is the Controler is alone, and none of the Router have move to the new channel.

Am I missing one step ?

here after is the the way ZPS_eAplZdpMgmtNwkUpdateRequest() is called:

u32ChannelMask = 0x00008000 // Channel 15

u8ScanDuration = 0xfE // Radio channel change

u8ScanCount = 0x00

u16NwkManagerAddr = 0x0000 // Controler network address

HI @zigbee1,

I am hope you are doing great.

I checked the variables that your are using. What is the Destination that you are using?

Please look at the values that I am using with the ZWGUI Tool.

Also, please look at the next image using a sniffer. I am seeing the NWK Update Request and also the router is sending the broadcast

At the end, the router changes jump to the channel that was set by the coordinator.

Regards,

Mario

Mario, thanks it works. My issue was that I was not using broadcast FFFF for the destination address but 0000 .
