Can there be two different coordinators in a big room?

You can disable permit join of Zigbee coordinator by default. When you want to join a device or router in to one of the Zigbee networks, you enable its permit join, and disable permit join again after you finish adding device or router.

Thank you very much for your answer.

I have some questions.

1  How to disable the permit of Zigbee coordinator?Can tell me in detail?

2 When I want to disable permit of one network, I have to close the coordinator and change the code ,How to guarantee the network does not collapse?

Looking forward to your answer

You can use ZDP_MgmtPermitJoin API to enable or disable permit join. There is no need to restart coordinator.

Hi, I do not know "ZDP_MgmtPermitJoin API" .Where is it? Could you tell me how to get it .

Thank you very much.

Hi,I have found the API  ZDP_MgmtPermitJoinReq according to your method,but I do not know how to prevent the other routers joining network after the 150 routers joining network .

1 After the 150 routers joining network  can I use this "ZDP_MgmtPermitJoinReq(&dstAddr, 0x00, 1, FALSE)"  to prevent the other routers .  Where to put it,if it works.

Could you show me the  way? 

Thanks again.

You csn use ZDP_MgmtPermitJoinReq to disable permit join of all other ZC and ZR. Only allow the specific router to enable permit join with ZDP_MgmtPermitJoinReq.

Thank you! I can solve my question.

Could you tell me more details about "ZDP_MgmtPermitJoinReq",or  give me some related information.

I want to study it.
