Hi,

Please see this post (note that the FICR approach from the other approach in that thread does not work from the app core on the nRF5340).

Hi

I tried these  bt_id_get() or bt_le_oob_get_local() they should not give correct mac address

Hi,

Ah, you are right, that does not work with the random static address. I tested now, and bt_read_static_addr() works. You can use it like this:

	static char addr_str[BT_ADDR_STR_LEN];
	struct bt_hci_vs_static_addr addr;
	int addr_count;

	addr_count = bt_read_static_addr(&addr, 1);

	if (addr_count > 0)
	{
		bt_addr_to_str(&(addr.bdaddr), addr_str, sizeof(addr_str));
		printk("BT addr: %s\n", addr_str);
	}

Note that you need the following includes:

#include <zephyr/bluetooth/hci_vs.h>
#include <zephyr/drivers/bluetooth/hci_driver.h>

And also need CONFIG_BT_HCI_VS_EXT=y in your prj.conf or similar.

Thanks for reply

I already include 

#include <zephyr/bluetooth/hci_vs.h>
#include <zephyr/drivers/bluetooth/hci_driver.h>

Hello,

I wanna read and write MAC address no matter it's public or static one,but must be the same one.

and I am using NRF52833DK, I know bt_read_static_addr() to get static MAC address via this this article.

Now I wanna set this address,do these any API to change it?
