Zigbee install codes list contend problem

[L.Hoffmann]

I am writing a coordinator application based on the zigbee CLI example.
I am using SDK for Thread and Zigbee v4.1.

I am using a function in zboss_api called zb_secur_ic_get_list(zb_uint8_t* table, zb_uint8_t *cnt) in order to get information about the added install codes. I found out that the content of the structure of returned back in “table” looks lik this:

 

typedef zb_uint8_t zb_128bit_ic_t[18];  /*!< 16 byte / 128-bit code * 2byte CRC.*/

typedef zb_128bit_ic_t zb_instal_code_t;

 

/** @brief Install Code Table Record Format */

typedef ZB_PACKED_PRE struct bdb_secur_ic_table_record_s

{

  zb_ieee_addr_t ext_addr;      /*!< 64-bit IEEE address that is unique to every device.*/

  zb_ic_types_t  icType;              /*!< install code type */

  zb_uint8_t bByte;                   /* Byte - definition   unknown */

  zb_instal_code_t instal_code; /*!< install code bytes + CRC */

}

ZB_PACKED_STRUCT

bdb_secur_ic_table_record_t;

 

So writing Install Codes with zb_secur_ic_add(…) and reading them back with zb_secur_ic_get_list(…) works fine:

 

Nr 0:

   Device Extended Address: 0x804B50FFFEE2756F

   Keytype: 3 (ZB_IC_TYPE_128)

   Key: 4205B841EB5656B86DF2F1887EFDBE032C37

   ?: 0

 

So I write, delete and read back install codes works perfect for some time. But at one point zb_secur_ic_get_list(…) only returnes back “0xFF” as contend of some install code entrys:

 

Nr 0:

   Device Extended Address: 0xFFFFFFFFFFFFFFFF

   Keytype: 255 (Unknowen)

   Key: FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

   ?: 255

 

The maximum number of install codes “ZB_CONFIG_N_APS_KEY_PAIR_ARR_MAX_SIZE” is set to 200.

Currently I am only using 15 install codes at the same time.

 

Do you have any Idea, what could possibly lead to that problem?

 

Best regards

Hi,

I am sorry for the late reply.

I cannot find zb_secur_ic_get_list() function in our documentation, so perhaps even if it may be part of the ZBOSS stack it may be a function not supported by our SDK. Anyways, could you perhaps share the code where you are using this function and printing it's results?

So I write, delete and read back install codes works perfect for some time. But at one point zb_secur_ic_get_list(…) only returnes back “0xFF” as contend of some install code entrys:

What function are you using to delete the install codes? Perhaps the zb_secur_ic_get_list() function is returning 0xFF if the content of the install code entry is deleted?

Best regards,

Hi Marjeris.

Thank you for your response.

In your cli example v4.1.0 you are using the function “bdb ic add <h:install code> <h:eui64>” to add install codes to the coordinator. In order to correctly use the install code policy to safely commission a Zigbee 3.0 network with over 100 nodes, I also need functions to delete and read back currently existing install codes. Can you please tell me which functions from your SDK I can use to do that?

Best regards

Hi Lutz,

Sorry for the late reply, I have asked our Zigbee developers for more information. In the zboss_api.h header there are declarations of multiple functions for install code management, some of them are not present in the Infocenter for some reason (we are looking into that).

zb_ret_t zb_secur_ic_add(zb_ieee_addr_t address, zb_uint8_t ic_type, zb_uint8_t *ic);
zb_ret_t zb_secur_ic_set(zb_uint8_t ic_type, zb_uint8_t *ic);
zb_ret_t zb_secur_ic_get_list(zb_uint8_t* table, zb_uint8_t *cnt);
zb_ret_t zb_secur_ic_get_by_idx(zb_uint8_t* param, zb_uint8_t index);
zb_ret_t zb_secur_ic_remove(zb_ieee_addr_t address);
zb_ret_t zb_secur_ic_remove_all(void);
zb_ret_t zb_secur_ic_str_set(char *ic_str);
zb_ret_t zb_secur_ic_str_add(zb_ieee_addr_t address, char *ic_str);

For removing install codes: zb_secur_ic_remove() - this is present in the infocenter

zb_secur_ic_get_list() should allow to read existing install codes (this was not in our documentation, so I wasn't aware of this function in my previous answer).

Best regards,

Marjeris
