CC2530DK: CC2530 assoc full,device can rejoin net

Part Number: CC2530DK
Other Parts Discussed in Thread: Z-STACK

HI~

I use Z-Stack Home 1.2.2a.44539 and set :

MAX_NODE_DEPTH                    1
NWK_MAX_DEVICE_LIST          0

NWK_MAX_ROUTERS                1

the zigbee architecture :

        C    (depth 0)

         |

        R   (depth 1)

I try to power off  and power on the router to simulate the router lost and  come back

.

1.the router can't join to the net

2.the coordinator assoc is 0 ( I think is AssociatedDevList full)

3.how to do when the router lost the parent and child to auto maintain the assoc list?

4.Z-Stack-Mesh-1.0.0 is the same result

    Can you attach original psd file?

    Hi Anson

    I think that you want the router to remember its previews network, so you have to enable the Nv, so make sure to have these flags enabled NV_INIT and NV_RESTORE in the preprocessor options of the project.

    Hi Anson Chen69,

    As Luis says, make sure to use the NV_RESTORE flag. Additionally 0xFFFFFFFFFFFFFFFF address on your coordinator is a reserved value by the IEEE association used to represent NULL addresses, uninitialized devices and in some cases a broadcast address or distributed security device so, mi recommendation is to change it to the default IEEE address or any different from 0xFFFFFFFFFFFFFFFF or 0x0000000000000000.

    I hope this helps,

    Regards

    the coordinator assoc is 0 but it doesn't mean AssociatedDevList is full. It means coordinator doesn't enable permit join at this moment. Do you enable NV_RESTORE when you test this?

    Power on R1, R1 can't rejoin to the zigbee (Beacon request)
    I know to enable NV_INIT and NV_RESTORE the R1 can use 0x031F return the net but that not i want

    ****************************************************************************************************************************
    1.
    I hope when R1 powerdown(simulate lost or damage), the R3 can join to the net but R1 parent AssociatedDevList id full( psd file can't see any disassociation notification)

    I hope is:

    C                                  C                                                 C

    R1      >>>>               R1(lost or damage)      >>>>  R3

    R2                               R2                                              R2

    R3                              R3
    (Beacon request)   (Beacon request)

    2.
    I use AssocRemove to do :
    C                                  C                                                      C AssocRemove child R1                                                                   C

    R1            >>>>          R1(lost or damage)    >>>>>                                                                                                        >>>>     R3

    R2                               R2                                                    R2 AssocRemove parent R1 and rejoin the zigbee                      R2
                                                                                                 
    R3                              R3                                                       R3
    (Beacon request)    (Beacon request)                             (Beacon request)

    but when the node is much. Idon't think it is good idea !!!!!!!

    So,have any suggest or idea

    If you don't enable NV_RESTORE, you have to enable permit join to allow device to join.

    Hi YiKai,
    You mean is coordinator permit join is disable. so the R1 power off and the R3 can't join the net not the coordinator assoc full.

    1.How to enable permit join ??

    2.I have try NLME_PermitJoiningRequest(0xFF) in the coordinator but not work. The R3 still is beacon request but AssocRemove the R1 don't do anything the R3 can join
  • 0 in reply to Anson Chen69
    Guru 735695 points
    1. Call NLME_PermitJoiningRequest(0xFF) on coordinator should enable permit join.
    2. Can you provide sniffer log with coordinator permit join enable but router cannot join? By the way, do you power recycle coordinator when you do this test?

    I have see this :
    e2e.ti.com/.../538280

    1.so you think when assoc full to enable Call NLME_PermitJoiningRequest(0xFF) the R3 should be join the net
    2.Can I use ZStack-CC2530-2.5.1a to provide sniffer log. Because I development is in ZStack-CC2530-2.5.1a, I just check it is improve in Z-Stack Home 1.2.2a.44539
    3.Do you know Chinese?

    Guru 735695 points
    1. No, when assoc full to enable Call NLME_PermitJoiningRequest(0xFF), the R3 shouldn't be join the net.
    2. Yes
    3. Yes

    Hi ~ YiKai

    about 1.~ I'm sure I'm the case.

    Is there any idea and advice can be solved?

  • 0
    Guru 735695 points
    Yes, your AssociatedDevList is full. It shows on Dev.Cap=0x0 in Beacon Payload (NWK Layer Decode).

    So~It is not bug in zigbee technology or TI thing It's not bug.

    If association table of ZC or ZR is full, no device can join.

    If the zigbee net device is full(all ZR) and when I remove the one ZR(damaged or can not work) form the net ,I can't add any other device.

    If i want to add new ZR to replace the damaged or can not work ZR.

    I only can do is reset the ZC to reorganization zigbee net.

    I think the remove ZR's(damaged or can not work) parent and child should be clean the remove ZR association recording to add the other new device.

    and one question: Are you TI engineer????

    thanks.
    about the this :
    If association table of ZC or ZR is full, no device can join.

    If the zigbee net device is full(all ZR) and when I remove the one ZR(damaged or can not work) form the net ,I can't add any other device.

    I think the remove ZR's(damaged or can not work) parent and child should be clean the remove ZR association recording to add the other new device.

    do you have any idea or suggest ??
  • 0 in reply to Anson Chen69
    Guru 735695 points
    If you leave ZR with leave request and get response, it would be remove from association table. However, if association table is full and this is not the case, there is no better alternative in Z-Stack Home 1.2.2a and previous stack. Z-Stack 3.0 has child aging and can handle this so I suggest you to use Z-Stack 3.0.

    Z-Stack 3.0 . Can solve my problem or may be able to solve my problem ??
    thanks!
    I will go to test.
