Oh, I actually don't need any helps.

I solved this problem myself.

I just respond brec's question.

So, I think you can close this.

Thanks for your note.

You should use that in any case. Have you resolved the issue, or does it still not work? If not, can you share your code so that I can see if I spot something?

For now I'm using "CONFIG_BT_LL_SW_SPLIT=y" in prj.conf file.

So that's why I should use bt_ctlr_set_public_addr().

Thanks for precise information.

Hi,

Note that if you use the SoftDevice controller, sdc_hci_cmd_vs_zephyr_write_bd_addr() is called when you call bt_ctlr_set_public_addr(). Specifically this is because the implementation of bt_ctlr_set_public_addr() when using the SoftDevice controller is like this (nrf\subsys\bluetooth\controller\hci_driver.c):

void bt_ctlr_set_public_addr(const uint8_t *addr)
{
	const sdc_hci_cmd_vs_zephyr_write_bd_addr_t *bd_addr = (void *)addr;

	(void)sdc_hci_cmd_vs_zephyr_write_bd_addr(bd_addr);
}

I just use the first one.

Thanks for let me know second one. 🙂

I solve this my own. I didn't know there are some APIs for that.

Anyway, I'll close this.
