Zigbee install codes

[Litvinus]

Hi,

my zigbee network for 120 sensors. if i declare 120 install codes then most of them don't work. The "zb_secur_ic_add" function works without error, "zb_secur_ic_get_list" returns the correct count, but the table is filled with either zeros and FF. If I declare 30 codes, then everything works correctly and the devices are added. the size of the memory has increased:

#define ZIGBEE_NVRAM_PAGE_SIZE 69632

#define ZIGBEE_NVRAM_PAGE_COUNT 2

#define ZIGBEE_NVRAM_CONFIG_PAGE_SIZE 4096

#define ZIGBEE_NVRAM_CONFIG_PAGE_COUNT 1

#include "zb_mem_config_max.h" 

#define ZB_CONFIG_OVERALL_NETWORK_SIZE  200

By the way, it seems that the function of "zb_secur_ic_get_by_idx" does not work correctly. returns -1. Moreover, if you declare codes for 30 devices, and then read the table, then the codes are not in the order in which they were announced. But everything is there. If you declare 100, then there is nothing at all.

Hi

What have you set ZB_CONFIG_N_APS_KEY_PAIR_ARR_MAX_SIZE to be large enough to fit this amount of install codes?

Best regards,

according to the description:

https://infocenter.nordicsemi.com/index.jsp?topic=%2Fsdk_tz_v3.1.0%2Fzigbee_mem_cfg_feature_ram.html&anchor=zigbee_mem_cfg_ram_feature_include

for the coordinator it is 

#define ZB_CONFIG_OVERALL_NETWORK_SIZE  200

#define ZB_CONFIG_N_APS_KEY_PAIR_ARR_MAX_SIZE ZB_CONFIG_OVERALL_NETWORK_SIZE

Hi,

I apologize for the delay.

I have asked our developers internally, and this seems to be related to a bug regarding NVRAM corruption after switching to another page. Our developers are investigating this and in discussion with DSR. I will update you when I have more information.

Best regards,

Marte

Hi,

The Zigbee team has managed to reproduce it on their side, and observed that the list returned by zb_secur_ic_get_list() is correct up to 31 install codes. Adding a 32nd install code will cause the list to be broken, and all install codes 1-31 will be filled with FF, while install code number 32 will still be correct. After this, new install codes will be correct, but will eventually be broken again after enough is added.

They do not have a solution for the problem yet, but they are still working on it.

Best regards,

Marte

Hi,

OK. Please let us know when solutions appear.

Hi,

This problem is not reproducible in nRF Connect SDK v1.7.0 with ZBOSS 3.8.0.1. It will be fixed in a new release of nRF5 SDK for Thread and Zigbee which will provide several bugfixes. 

Best regards,

Marte
