CC2530 Permit Join and Leave Problem

Shashank Shah

Hi Friends,

I have two issue:-

1.) I am trying to send join permit broadcast to all the device in the network. But it isn't working. Command(ZDO_MGMT_PERMIT_JOIN_REQ) parameters are :-

Address type - broadcast(0x0F)

DstAddr - 0xFFFF

Duration - 0

TCSignificance - 0

When I try to send individual permit joins, it works fine.

2.) I have network as shown below

ZC-----------ZR1------------ZR2

When I try to issue leave network command(ZDO_MGMT_LEAVE_REQ) from ZC to ZR1, it immediately leaves the network. But if I issue the same command from ZC to ZR2, it doesn't work.

Need Help.Thanks.

1. Duration 0 means disable permit join. Try to use 255 as duration which means enable permit join forever.
2. I suggest you to use Ubiqua Packet Analyzer to check why it doesn't work.

Dear YK,

I want to disable join permit, so I have kept duration 0.

Am I missing some compilation flag?

Thanks.

If you keep duration as 0, it would disable permit join. You have to set duration to 255 when you want to allow device to join and set it to 0 when you want to disallow device join.

Dear YK,

I have solved the problems-

Problem 1:

To disable permit join throughout the network, I have to first send broadcast permit join disable (for all other devices) and then disable permit join for ZC.

Problem 2:

I have added MT_ZDO_FUNC, MT_ZDO_MGMT compile flags.

DstAddr should be parents address or device's address that we want to leave. ( only a parent can ask a child to leave or child itself can leave)

Thanks for help.
