Hi Charlie,

That was the best information I need during some days, so I could have the appropriate treatment.

Thank for your help.

Hi VDMinh,

Sorry, I did not realize your test environment also has another ZC enabled with a different PAN ID.

It is quite tricky on your use case. Zigbee is initially designed or try to avoid static PAN ID on practice usage. NCS will not have much difference since it uses the same ZBOSS stack. It will also have security concerns on this kind of Zigbee network, return back to dynamic PAN ID seems a good idea. I do suggest you switch to NCS as soon as possible for your development, the new version ZBOSS stack used by NCS has fixed some critical bugs. nRF5 SDK Thread_Zigbee_v4.1.0 is currently in the maintenance stage now, there will be no major update in the future.

Best regards,

Charlie

Hi Charlie,

Did you test carefully. I relize the issue is still stay there.

As you can see below, ZED can not join to right PAN.

I tried many ways, such as other API, but it not better.

Did NordicSemi team foresee this satuation, now I begin disbelieve about static PANID setting, and maybe I return back dynamic PANID, or tranfer to nCS.

Thank you.

Hi Duc,

I checked your source code and find the issue. Here I list all the modification need to be done based on original exmaples:

light_bulb: change to "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" in main.c line 71

light_switch: change to "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" in main.c line 66

light_coordinator: add "ZB_PIBCACHE_PAN_ID()=0xABCD;" to "zigbee_helper.c" line 282

Best regards,

Charlie

Hi Charlie,

I tried above ways many times, and it wasn's better.

Because test results of us were different, so I give you my code, could you check them.

https://www.dropbox.com/s/hoigni3n3qe0ln3/light_control.rar?dl=0

The code is been " C:\Nordic_Semi\Thread_Zigbee_v4.1.0\examples\zigbee\light_control "

Thank you.

Hi VDMinh,

For the ZC, I modify the "#define ERASE_PERSISTENT_CONFIG ZB_FALSE" then it can pass the tests you specified on my setup now.

Remember to "Erase All" before you program the new firmware.

Best regards,

Charlie

Hi Charlie,

The commands you added that I did before, now I check it again.

The work case happen, then it's will fault after reset ZC / Bulb / Switch. I give you some results of test.

1. Bulb and Sw didn't get PAN_ID, Sw couldn't send data to Bulb.

I did step by step:

And logs were got:

2. Bulb and Sw booted to seem right PAN_ID, but they didn't work:

And logs were got:

Do you think I should shutt off PAN scan ? If can, how to do it ?

Thank you.

Hi VDMinh,

Sorry, I did more test today, move "ZB_PIBCACHE_PAN_ID()=0xABCD;" to "zigbee_helper.c" line 282 should work now.

For "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" in zigbee_helper.c, I actually mean main.c. I have correct the former answer to avoid confusion. I suggest you modify this definition on all the three examples. For the coordinator, it will always create a new network with PAN ID 0xABCD. For the other two devices, they will join the coordinator formed network instead of their former cached one.

Best regards,

Charlie

Hi Charlie,

* I tried to add "ZB_PIBCACHE_PAN_ID()=0xABCD;" to "zigbee_helper.c" line 472 in ZC, but it's still not ok, even worse.

* About "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" in zigbee_helper.c, I'm not real clear, what is ERASE_PERSISTENT_CONFIG affect in "zigbee_helper.c", I think it has influence a bit in only "main.c". Could you explain more.

Thank you.

Hi VDMinh,

Thanks for explaining your use case.

Can you add "ZB_PIBCACHE_PAN_ID()=0xABCD;" to zigbee_helper.c line 472?

also make sure "#define ERASE_PERSISTENT_CONFIG ZB_TRUE" in main.c.

NCS should also have similar settings that can set static PAN ID.

Charlie

Hi Charlie,
Example, you can see below image:

Incidentally, we have two factorys, side by side.
They are two different systems, different ZCs, different Servers, and maybe two different owners.
By using dynamic pan_id, maybe ZED 1.3 connect to ZC 2, that is also incidentally.
And we implement for factorys, we don't wanna to use binding/finding, just power on and running.

I think like as IP address, someone uses dynamic, another use static, dependent their situations.
About us, for many reasons, we choose static pan_id, in our stage it's more convenient, like as 10 points versus 9.5 points.
I agree with you, I have to manage for conflicting.

With nCS, could this issue solved satisfactorily ?

Thank you.

Hi VDMinh,

Can you explain your purpose to set static PAN ID for those devices?

As far as I can understand, PAN ID is just like the IP address for the Zigbee network, I am not sure what will happen when you set two devices with the same PAN ID. As a Zigbee application developer, I do not think you should work on the bottom level so much.

Hi Charlie,
I'm still work on "Thread_Zigbee_v4.1.0", cause I added few functions base on this flatform. Now, I haven't switched to nCS yet.

I tested "light_coordinator" and "light_bulb" with below configuration:

But, I relized that pan_id was not stable (see below image):
Step 1. ZC power on, it has 0xABCD pan_id, that's right >> Bulb power on, Bulb also has right pan_id
But:
Step 2. Just resetting only ZC, it has other random pan_id
And:
Step 3. Continues resetting only ZC, it has another one pan_id

>> So, "ZB_PIBCACHE_PAN_ID()" is not achieve my wish. Please give me more guidances.

Thank you.

Hi Duc Minh Vo,

I believe you should be able to set PAN ID with ZB_PIBCACHE_PAN_ID(). This must be done before the stack is started. Additionally, this only works if it does not have an existing PAN ID stored, so you need to have ERASE_PERSISTENT_CONFIG set to ZB_TRUE.

I kindly remind you to switch to NCS if you are still in the early stage of your development. The nRF5 SDK is currently in the maintenance stage and its Zigbee stack is a bit out of date, you can find more information here: nRF Connect SDK and nRF5 SDK statement.

Best regards,

Charlie
