Other Parts Discussed in Thread: Z-STACK

Hi all,

We use Z-Stack 1.2.2 and have sniffer with below log

/cfs-file/__key/communityserver-discussions-components-files/158/150923_5F00_End_2D00_Device-join-fail.zip

This fail sniffer is coordinator perform permit join through broadcast that association through router and update device to trust center,but not be allow from trust center that remove it. Router send leave command and not rejoin to this device.

Then we try use the other router perform permit join through broadcast like below sniffer log

/cfs-file/__key/communityserver-discussions-components-files/158/150923_5F00_End_2D00_Device-join-through-router-permit.zip

that association from router and update device be allow from trust center that send out Tunnel transport key to end device

What status trust center will reject child and send remove device?

Please help this. thank you.

Best Regards,

Ethan Chen

    Hi Ethan,
    A major difference between the two logs is the time delay between the original permit-join command, and the actual association. In the unsuccessful case, this delay is almost as long as the permit-join timeout. To rule out the possibility that the permit-join timed out before the trust center receives the update-device, can you please repeat the problematic scenario with a much shorter delay?
    Can you please list the details of all the argumemts you use with the permit-join command (especially the address mode - whether it is set to Addr16Bit (2), AddrBroadcast (15), etc, as well as the other arguments)?
    Best regards,OD

    Hi OD,

     

    I have checked this issue and find why trust center remove device?

    Because of our customer perform permit join follow TI's example code that always set the significance bit to true.


    if someone router sends out ZDP_MgmtPermitJoinReq through broadcast and PermitDuration is disable with significance to true that

    trust Center authentication will be disallowed with the effect that if an APSME-UPDATE-DEVICE.indication is received indicating that a new device

    has joined, The Trust Center shall then issue an APSME-REMOVEDEVICE.request to refuse the new device.
