NCS scan request filter dosen't work

[Allen23122452121]

Hi:

CONFIG_BT_FILTER_ACCEPT_LIST=y;

...

static const struct bt_le_adv_param *adv_1_param =

    BT_LE_ADV_PARAM(BT_LE_ADV_OPT_NOTIFY_SCAN_REQ|BT_LE_ADV_OPT_SCANNABLE|BT_LE_ADV_OPT_FILTER_SCAN_REQ,

            Ta1/0.625,

            Ta1/0.625,  

            NULL);

...

 err = bt_addr_le_from_str("FF:EE:DD:CC:BB:AA", "random", &addr);

   err = bt_le_filter_accept_list_add(&addr);

it dosen‘t work,why?

scanner MAC has beed set("FF:EE:DD:CC:BB:AA"):

Looking forward to your reply.

Hello,

Can you elaborate a bit what doesn't work?

For test maybe try to set all address bytes to the same value, I suggest "C3", reason for trying this is that it will ensure the problem is not related to endianness of the address.

Thank you for your reply!

I found the problem but i don't know why;

I printk the address of my scanner in "bt_le_ext_adv_cb.scanned" and i find scanner always changes its random address every time i reset the board.Even if i set the random address as follows:

Do you know why?Could you help me?

Best wishes

Sounds like things are working then. 

From \zephyr\include\zephyr\bluetooth\bluetooth.h you can find:

 * If the application wants to have the stack randomly generate identities
 * and store them in flash for later recovery, the way to do it would be
 * to first initialize the stack (using bt_enable), then call settings_load(),
 * and after that check with bt_id_get() how many identities were recovered.
 * If an insufficient amount of identities were recovered the app may then
 * call bt_id_create() to create new ones.

I expect the problem here is that you don't have settings_load().
