RTOS/CC2538: PAN ID and Connection for Coordinator and Router

Hi YK,

Please see the attached ubiqua. This time retry, one of the router can be link. but the other still have PAN ID 0x1235.

By the way,  in the init function, I put the following setting, I am not sure whether it is related to this issue or not.

Actually, what I expected is after power up all the coordinator, router, End device. They will automatically link together to form a one big network!!

(So, please let me know if there exist any potential problem when I use the following settings)

In Coordinator (CC2538, Zstack 3.0.1),

  bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_FINDING_BINDING);

  NLME_PermitJoiningRequest(255);

In Router (CC2530, Zstack 3.0.1),

  bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_NWK_STEERING | BDB_COMMISSIONING_MODE_FINDING_BINDING);

   NLME_PermitJoiningRequest(255);

In End Device (CC2530, Zstack 3.0.1),

  bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_FINDING_BINDING);

Hi YK,

Ok. let me try.

But you said "enable network steering on ZC" , so, the changes in Coordinator(See red) is as follows: Please confirm.

 bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_NWK_STEERING| BDB_COMMISSIONING_MODE_FINDING_BINDING);

 NLME_PermitJoiningRequest(255);

About ZR, could you please tell me how to do factory reset on ZR?

Thank you very much

Hi YK, Ryan,

After trying , the following bdb_startCommissioning setting seems OK (for 1st time to join only).

For Coordinator:

bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_FORMATION | BDB_COMMISSIONING_MODE_NWK_STEERING |BDB_COMMISSIONING_MODE_FINDING_BINDING |BDB_COMMISSIONING_MODE_INITIATOR_TL);

 NLME_PermitJoiningRequest(255);

For Router:

bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_STEERING | BDB_COMMISSIONING_MODE_FINDING_BINDING | BDB_COMMISSIONING_MODE_INITIATOR_TL);
  NLME_PermitJoiningRequest(255);

For End Device:

bdb_StartCommissioning(BDB_COMMISSIONING_MODE_NWK_STEERING | BDB_COMMISSIONING_MODE_FINDING_BINDING);

Problem discovered: 
When the Coordinator, Router program are downloaded and join in the 1st time, it success!! (I use ubiqua to check, the network depth (Coordinator) is 0, the network depth (Router) is 1). 
But after Coordinator and Router are reset power and try again, Coordinator and Router cannot rejoin!! (ie.,  the network depth (Coordinator and Router) are all 0 !!)
The End device rejoin seems OK.

So, is there any further setting required such that Coordinator and Router can be rejoined after power reset?  

Thank you very much
Bruce Lam

 

Dear YK,

Please see the attacahed rar file. (the pdf has elaboration).

Based on my understanding, in Zigbee connected network, the depth of the coordinator is 0, the child of the coordinator (either router or End device) has the depth 1. So, I expect when Coordinator and the router are join together, the depth of ZC should be 0; depth of ZR should be 1. (If my conclusion is wrong, pleasae correct me)

In ubiqua data, when ZC and ZR are 1st join, it is OK.

After ZC and ZR power reset, all the depth are 0. So, that's why I said "ZC and ZR cannot rejoin after power reset".

Thank you very much

Hi Bruce,

What hardware and example applications do you use to replicate the issue? Please list all changes made to Z-Stack variables. Have you followed any changes are recommended in the Known Issues Wiki? processors.wiki.ti.com/.../Zigbee_Known_Issues_and_Proposed_Fixes

On a side note, you do not need to enable BDB_COMMISSIONING_MODE_INITIATOR_TL if you are not using the TouchLink feature.

Regards,
Ryan

Hi Ryan,

For Coordinator(CC2538),  

I based on GenericApp to modify  (folder path "Home Automation -- GenericApp-- CC2538") .

About the hardware, it is 3rd party zigbee cc2538 gateway(i.e., CC2538 + WIFI IC).

For Router (CC2530) /End device (CC2530),  

I based on GenericApp to modify  (folder path "Home Automation -- GenericApp-- CC2530DB") .

About the hardware, it is 3rd party zigbee cc2530 development board.

About the list of changes(ZC and ZR) made to Z-Stack variables, please see attached setting. (if you found anything wield about the setting, please let me know)

Note: if you want to see ZED Zstack variable changes, please let me know.  

About" the known issue and proposed fix in wiki"(i.e., the link you provided), I have not yet tried when I start to raise my question in the forum.

About the list of the proposed fix, I did the following proposed fix a while ago but the problem still exists!!

2.1 Memory Leak in zcl.c

2.2 Network association issues after prior APS Remove or Leave Request

2.3 Soft Reset/Freezing/Stack Overflow due to BDB_REPORTING on CC2530/CC2531

2.15 Errors due to BDB header build types    (Due to the fact that I cannot found znp.cfg, so assume I don't need to handle this issue, am I correct please?)

But anyway, let me try the other proposed fix.  But please let me know when you have idea about what's wrong in my ZC,ZR Zstack settings.

Thank you very much in advance

Hi  YK,

As I remember, after ZC ZR power reset, some of the ZEDs cannot be controlled through ZC. (But I am not aware whether the lost control ZEDs are the one which is linked to the router!!).   But anyway, let me double confirm in my side.

Yes, in  20190218 (First join-- OK).cubx, it works fine, all ZEDs can be controlled.  But after ZC, ZR power reset, there exists no DEVICE ANNOUNCE data in ubiqua capture which is strange..

By the way, I come up with 1 thing about Zstack which need to be clarified:

(1) In Zstack structure design, when I do join device (ZR /or ZED), is it necessary for the user to "press button(as default) when power up" and then Zstack will jump into something like "Network adjustment mode"?  Actually, I have no buttons in our ZC, ZR and ZED product!!

Thank you very much in advance

Hi Ryan, YK,

About Ryan mention "silent rejoin", I suddenly remind 1 thing:

Please confirm whether  ZDO_STATE_CHANGE will be triggered or not after silent rejoin.  If not,  is there any event trigger for "silent rejoin"? 

Actually, after ZED join /rejoin the network, I assume ZDO_STATE_CHANGE will be triggered and do some hand shaking between ZED and ZC. (Please see the code below)

Then, the ZC will get my "self-defined" DeviceID from ZED.  And then, my program in ZC can control the ZED based on the "self-defined" deviceID.

____________________________________________________________________________________ 

zclXXXXXX_event_loop( uint8 task_id, uint16 events )

{

      .....

       case ZDO_STATE_CHANGE:

         zclBEC2_0_R1App_NwkState = (devStates_t)(MSGpkt->hdr.status);

             if ( (zclBEC2_0_R1App_NwkState == DEV_ROUTER) || (zclBEC2_0_R1App_NwkState == DEV_END_DEVICE) )

              {

                        ...For end device, I put some code here to send data(include "self defined device ID") to ZC ...

              }

 }
