CC2538: Backup ZC /Concentrator/Gateway in Zigbee network

Dhanraj

Part Number: CC2538

Hello,

Is it possible to configure one of the Zigbee device as a Backup ZC/Concentrator/Gateway in zigbee network so that if primary ZC fails , in that case backup ZC can takeover ??

Try to refer to sunmaysky.blogspot.tw/.../how-to-clone-existing-z-stack.html

so basically we can not pre configure one of the node as backup ZC?

Why not? The steps in the link show you how to do it.

suppose If i clone data to the Backup ZC, and now my both ZC are On then, there will have pan conflict event ?

Yes. But, why do you do that?

off course , i will not do that. was just verifying my understanding.

1) Enable Compiler option MT_SYS_KEY_MANAGEMENT on coordinator.

> is it required on both ZC , ORIGINAL and BACKUP ?

2) Use MT command to read out the following NV items from coordinator that you want to clone.

> this step should be be carried out using Z-TOOL??

3) Also in the comment someone mentioned that -

If you are using the BDB commissioning interface, you have to initialize other nv items like the addrMgr, for which is very convenient to create a network and power cycle the device, after which you can write the nwk parameters of the ZC to be cloned. Also you have to write ZCD_NV_BDBNODEISONANETWORK to TRUE so bdb can restore the nwk parameters.

Additionally, you have to take care of the security material table ZCD_NV_NWK_SEC_MATERIAL_TABLE_START, which is the frame counter + the Ext PAN ID of the network, also you can use the debugging MT interface to match the nwk frame counter of the cloning device.

1. I suppose you should have it on both in case you need to backup the backup one someday.
2. It’s not mandatory to use ZTool. You can use other host that can support MT/ZNP command to do it.
3. I shouldn’t be mandatory.
