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?

Regards,

Matin

Thanks for reply

I already include

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

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.

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

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).
