Part Number: CC2538
Other Parts Discussed in Thread: Z-STACK, TIDC-ZNP-HOST-SW3, Z-STACK-ARCHIVE, CC2592

Hello E2E Community,

I am trying to Set the Link Key for the ZNP device uising the uint8_t zdoSetLinkKey(SetLinkKeyFormat_t *req) function in znp host framework application.

Params :

ShortAddr : 0x0000 (short addr of the znp device)

IEEEaddr[8] : 0x00124B00193C4192 (ieee addr of the znp device)

LinkKeyData[16] : 5A:69:67:42:65:65:41:6C:6C:69:61:6E:63:65:30:39 (default zigbee link key "ZigBeeAlliance09")

I am getting the following response for the ZNP device (CC2538)

[2020-01-08T17:33:33.3+05:30][INFO]-    SOC OUT --> LEN :1A, SOF :FE, CMD0 :25, CMD1 :23, Payload :00:00:00:12:4B:00:19:3C:41:92:5A:69:67:42:65:65:41:6C:6C:69:61:6E:63:65:30:39, FCS :8D

Will you please help me to know,

Am I doing any this wrong?

How do I set the Link key for a ZNP device to add the other devices in network using the link key?

Which Z-Stack version do you test this and do you try to use ZTool?

0 Ryan Brown1 over 6 years ago

Hello Shiv,

I assume you are using Z-STACK-ARCHIVE HA 1.2.2a as this is the stack used by TIDC-ZNP-HOST-SW3. First make sure that MT_SYS_KEY_MANAGEMENT is defined in your ZNP project as this is not the case by default.

Ryan

Hello Ryan Brown1,

I have enabled the MT_SYS_KEY_MANAGEMENT flag on the ZNP device code & now I am able to get the successful response form the ZNP device for the uint8_t zdoSetLinkKey(SetLinkKeyFormat_t *req);

Now I wants to add the device in network which also has configured the same zigbee link key.
But I am unable to add the device in to the network.

Will you please help me to know,

1. The params I have mentioned above are valid or not?

(should I give the ieee & short addr of ZNP device or the device which should be added to network)

2. Is there any other configuration requied that will enables the permit joining for those devices who has configured the link key?...

Regards,

Shiv Patil.

1. ShortAddr: Specifies the short address of the pair device ofthe link key, IEEEAddr: Specifies the IEEE address of the pair device of the link key.

2. You still need to enable permit join.

Hello YiKai Chen,

Will you please let me know what do you mean by pair device?

Is it ZNP device or the device which must be added to the network.

Shiv Patil.

0 YiKai Chen over 6 years ago in reply to shiv patil

Guru 735695 points

It means the device which you want to add to the network.

Hello YiKai Chen,

Thanks for clearification.

Will you please help me to know,

How do I am able to know the short addr of the device before adding it in to the netwrok?..

Is it perdefined in the perticular deivce code stack or there is a default value for it?...

Regards,

Shiv Patil.

Hello Shiv,

You have to use the DEFAULT_TC_LINK_KEY or install codes for joining devices, afterwards you can modify the application or TC Link Keys accordingly. http://dev.ti.com/tirex/explore/node?node=AES5VdxyX-.OXxWoIFsyPg__pTTHBmu__LATEST&r=pTTHBmu__

Another option I've never tested is MT_AppCnfBDBSetActiveCentralizedKey with keyMode set to zstack_UseAPSKey.

Hello ,

Will you please let me know,

How do I enable the DEFAULT_TC_LINK_KEY on the CC2538 ZNP device so that,

any devices with the link key will automatically added to the netwrok with out setting any configurations?

0 YiKai Chen over 6 years ago in reply to shiv patil

Guru 735695 points

DEFAULT_TC_LINK_KEY is enable by default on the CC2538 ZNP device

0 shiv patil over 6 years ago in reply to YiKai Chen

Genius 3356 points

Hello YiKai Chen,

If I try to add a sample device with default zigbee link configure to the znp device,

The device will not getting added to the network.

I have enabled following flags on ZNP compilation configuration

NV_RESTORE
TC_LINKKEY_JOIN
MT_SYS_KEY_MANAGEMENT
HAL_PA_LNA_CC2592

Should I do any other configuration to enable the default link key?

Why Device will not getting added unless I am set the link key using uint8_t zdoSetLinkKey(SetLinkKeyFormat_t *req)?....

Regards

Shiv Patil.

There’s no need to do any extra step as I know. May I know which Z-Stack/ZNP version you test?

0 shiv patil over 6 years ago in reply to YiKai Chen

Genius 3356 points

I am using the Z-Stack 3.0.2 / CC2538 ZNP device.

& the end device will configure with following defalut zigbee link key

//#define DEFAULT_ZIGBEE_LINK_KEY {'Z', 'i', 'g', 'B', 'e', 'e', 'A', 'l', 'l', 'i', 'a', 'n', 'c', 'e', '0', '9'}
#define DEFAULT_ZIGBEE_LINK_KEY {0x5A, 0x69, 0x67, 0x42, 0x65, 0x65, 0x41, 0x6C, 0x6C, 0x69, 0x61, 0x6E, 0x63, 0x65, 0x30, 0x39}

If I am tyring to add device in to the network using the permit joinning request the device will not getting added to the network.

Will you please help me to solve this problem?...

Do you use sniffer to check what happens over the air?

0 Ryan Brown1 over 6 years ago in reply to YiKai Chen

TI__Guru**** 223557 points

Shiv,

What is the Zigbee Specification of the device you are attempting to join, 3.0 or HA 1.2.2a? If pre-Zigbee 3.0 then make sure that BDB_DEFAULT_TC_REQUIRE_KEY_EXCHANGE is false on the ZNP. As YK mentioned a sniffer log will greatly aid in debugging the issue.

Ryan
