Part Number: CC2530

Hello!

I am using several coordinator and several end device.

I hope that any end device communcate to proper coordinator with same channel.

But now any end device can't find it's coordinator.

Every coordinator can know only one end device's IEEE address.

Please help me.

Thanks in advance.

I couldn't under your scenario. If you have several coordinator and form different Zigbee networks, you should only enable permit joint on the coordinator that you want device to join to make device join. Then, they can start to communicate.

Hello YiKai Chen

Thanks for your reply.

I gonna match one coordinator and one end device.

In this way,I have several coordanators and several end devices.

Coordinator consist of cc2530 and WiFi module,cc2530 communication with wifi module by using UART.

So, I can register IEEE address of end device to coordinator through inteface of wifi module.

Sorry for my poor paint skill.

I hope that every end device communcate with it's coordinator.

Hello YiKai Chen.
In one room,I established several coordinators and several end devices.
Any end device join to other coordinator.
I am using same channel for several coordinators.

I have give you solution in my first reply. Only enable permit join on one coordinator at a time to enable specific device to join.

Hello YiKai Chen.

Questions:
1) When Coordinator know IEEE address of end device,end device can only join to the coordinator?
2) When coordinator run after backoff for long time,end device can only join to the coordinator?

Problem:
1) All coordinator use same channel.

I hope your full understanding.

1. You can implement white list on your coordinator to only allow device with IEEE address on white list to join and stay. Coordinator can send leave request to other devices that are not on the white list.
2. If you enable NV_RESTORE on your coordinators and devices, there is no problem.

It doesn't matter all coordinators use the same channel.

Hi YiKai Chen.

I came here I have one question.
You write "It doesn't matter all coordinators use the same channel."

What happen that several coordinator use same PAN ID?

Thanks in advance.

If those coordinators are on the same channel and there is PANID conflicts, coordinator will increase PANID to generate new PANID.

Thanks for your reply.

if coordinator increase PANID to generate new PANID,how to know changed panid of it's coordinator for those end devices?

0 YiKai Chen over 8 years ago in reply to Piaozhun

Guru 735695 points

If I remember correctly, device would turn to orphan state and send beacon request to find original Zibee network with new PANID.

0 Piaozhun over 8 years ago in reply to YiKai Chen

Expert 2620 points

You mean that end device increase PANID to generate new PANID too?

0 YiKai Chen over 8 years ago in reply to Piaozhun

Guru 735695 points

There is another information called ext PANID which is unique for every Zigbee network. When PANID changes, device would try to find original Zigbee network with ext PANID.
