Is there any pass Key in Zigbee with Zstack Home 1.2.1 like bluetooth. I want my device to join in my network only, it should not join to other Coordinator. And same my Coordinator should allow to join only my Ende device or Router. How can i achieve this

You can change TC_LINK_KEY to your private one.

Where to change it. where is TC_LINK_KEY

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

You can change -DDEFAULT_KEY="{0x5A, 0x69, 0x67, 0x42, 0x65, 0x65, 0x41, 0x6C, 0x6C, 0x69, 0x61, 0x6E, 0x63, 0x65, 0x30, 0x39}" in f8wconfig.cfg.

I have used same key as mentioned above by you in ZC and i changed the key in End device. But End device is joining to that ZC

ZED with different key would associate with ZC. However, the TC_LINK_KEY is different so ZED would be unauthenticated and would leave the network about 10 seconds later.

Thanks YK, but it is not leaving the network. By the way who will initiate the leave request, ZED or ZC?

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

ZED should initial the leave.

Yk, it is not happening, it is joining but it is not leaving from the network. The following changed i have done, uint8 zgPreConfigKeys = TRUE;

in ZGlobal.c and the Compile options are
ewarm
CC2538_USE_ALTERNATE_INTERRUPT_MAP=1
FEATURE_RESET_MACRO
SECURE=1
TC_LINKKEY_JOIN
xNV_INIT
xNV_RESTORE
xHOLD_AUTO_START
ZTOOL_P1
MT_TASK
MT_APP_FUNC
MT_SYS_FUNC
MT_ZDO_FUNC
xLCD_SUPPORTED=DEBUG
MULTICAST_ENABLED=FALSE
ZCL_READ
ZCL_WRITE
ZCL_REPORT
xZCL_EZMODE

ZCL_IDENTIFY
ZCL_ON_OFF

FEATURE_SYSTEM_STATS
xHAL_PWM
HAL_LED=FALSE

If you use TC_LINK_KEY, you should set zgPreConfigKeys=FALSE.

0 Johnson E over 10 years ago in reply to YiKai Chen

I have changed that also, but it is joining and sending the data also

Do you use Ubiqua Packet Sniffer to check over the air messages?

0 Johnson E over 10 years ago in reply to YiKai Chen

Intellectual 270 points

I used packet sniffer from TI. End device is sending data request and sending data for every second

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

Can you attach sniffer log so I can have a look?

0 Johnson E over 10 years ago in reply to YiKai Chen

Intellectual 270 points

I have attached the log 6114.Link.psd

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

After checking your sniffer log, your ZED joins ZC which means the TC_LINK_KEY is not changed on your ZED. I suggest you to erase the flash on your ZED and try again.

0 Johnson E over 10 years ago in reply to YiKai Chen

Intellectual 270 points

Yes, i have erased the Flash and flashed it.
In ZC, i used
-DDEFAULT_KEY="{0x01, 0x03, 0x05, 0x07, 0x09, 0x0B, 0x0D, 0x0F, 0x00, 0x02, 0x04, 0x06, 0x08, 0x0A, 0x0C, 0x0E}"

In ZED i used
-DDEFAULT_KEY="{0x01, 0x03, 0x05, 0x07, 0x09, 0x0B, 0x0D, 0x0F, 0x00, 0x02, 0x04, 0x06, 0x08, 0x0A, 0x0C, 0x0D}".

When i debug, "osal_memcpy( zgPreConfigKey, defaultKey, SEC_KEY_LEN )" is giving same key what i have set.
How can i know in sniffer, what is the key of ZC and ZED. So that i can check myself in the sniffer.

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

I suggest you set breakpoints at the line "osal_memcpy( zgPreConfigKey, defaultKey, SEC_KEY_LEN )" on both side of ZC and ZED. When ZC and ZED stop at these breakpoints, check the value of defaultKey on ZC and ZED.

0 Johnson E over 10 years ago in reply to YiKai Chen

Intellectual 270 points

As i told in previous post, the defaultKey is same as i set in the DDEFAULT_KEY. But it is joining.

0 Johnson E over 10 years ago in reply to Johnson E

Intellectual 270 points

Is there any thing i set. I tried lot. But it is still joining to Coordinator.

0 YiKai Chen over 10 years ago in reply to Johnson E

Guru 735695 points

Sorry, I make a mistake in replying you about TC_LINK_KEY settings. Actually, you have to change DEFAULT_TC_LINK_KEY in nwk_globals.h not DEFAULT_KEY in f8wconfig.cfg. Please revise it and try again. I have tested it on my EVBs and it works as expected. When a ZED uses different TC_LINK_KEY, it will get authenticated fail and reboot about 10 seconds later.

Thanks Yk, it's working now.

Nice to know it works now. By the way, please help to verify my answer to benefit others that have the same question.
