How to make larger STM32WB55 ZigBee Neighbours Table size

[JayRullia]

Hi.

I am working on a ZigBee project for the STM32WB55. 
I use Zigbee wireless binary of STM32Cube_FW_WB_V1.16.0 as below.

stm32wb5x_Mac_802_15_4_fw.bin, stm32wb5x_Phy_802_15_4_fw.bin, stm32wb5x_Zigbee_FFD_fw.bin. 
It works well for now with using 

zigbee_app_info.zb = ZbInit(0U, NULL, NULL);

Now I need larger nwkNeighborTblSz  to have more nodes, I tried following code.

static void APP_ZIGBEE_StackLayersInit(void)
{

struct ZbInitTblSizesT tblSizes;

tblSizes.nwkNeighborTblSz = 64;

tblSizes.nwkRouteTblSz = 32;

tblSizes.nwkAddrMapTblSz = 32;

tblSizes.nwkBttSz = 32;

tblSizes.nwkRReqSz = 16;

tblSizes.apsPeerLinkKeyTblSz = 32;

tblSizes.heapSz = 32*1024;

tblSizes.heapPtr = malloc(tblSizes.heapSz);

zigbee_app_info.zb = ZbInit(0U, &tblSizes, NULL);

}

My board does not come alive..
So I tried below codes but the board does not come alive.. 

tblSizes.nwkNeighborTblSz = 64;

tblSizes.nwkRouteTblSz = 32;

tblSizes.nwkAddrMapTblSz = 32;

tblSizes.nwkBttSz = 32;

tblSizes.nwkRReqSz = 16;

tblSizes.apsPeerLinkKeyTblSz = 32;

tblSizes.heapSz = 0;

tblSizes.heapPtr = NULL;

zigbee_app_info.zb = ZbInit(0U, &tblSizes, NULL);

1. Anyone can tell me what is wrong in the codes?

2. They say the default value of nwkNeighborTblSz is 64 but I see only 16.

I use  FFD (stm32wb5x_Zigbee_FFD_fw.bin) as wireless binary and use

zigbee_app_info.zb = ZbInit(0U, &tblSizes, NULL);

And the default value of apsPeerLinkKeyTblSz is said as 32 but I see also only 16.

Anybody can help me by anwer the upper questions?

Thanks in advance.

Hi. everyone.. 
Actually I got an answer why the following code does not work.. 

static void APP_ZIGBEE_StackLayersInit(void)
{

struct ZbInitTblSizesT tblSizes;

tblSizes.nwkNeighborTblSz = 64;

tblSizes.nwkRouteTblSz = 32;

tblSizes.nwkAddrMapTblSz = 32;

tblSizes.nwkBttSz = 32;

tblSizes.nwkRReqSz = 16;

tblSizes.apsPeerLinkKeyTblSz = 32;

tblSizes.heapSz = 32*1024;

tblSizes.heapPtr = malloc(tblSizes.heapSz);

zigbee_app_info.zb = ZbInit(0U, &tblSizes, NULL);

}

I chaged tblSizes as global variable and the machine begin to work as I expected..

I guess 
ZbInit(0U, &tblSizes, NULL) keeps using tblSizes variable after returning non-null zigbee stack pointer.

Here I write the answer to my question because I want other guys to see it avoiding same mistake.

Good luck.
