Custom MAC address for each advertising sets

[Nilon123456789]

I'm playing a bit with the multiple_adv_sets sample code and I want to be able to control the MAC address for my  non connectable adv and for the connectable adv. I tried to set the flag BT_LE_ADV_OPT_USE_IDENTITY but it only made the nrf switch bettwen the same MAC address. Is there a way to set one custom MAC address for each?

Found how! 

You need to set in your advertising parms an id and set the option BT_LE_ADV_OPT_USE_IDENTITY
then you need to create two ids.

You also need to add in your prj.conf this line

CONFIG_BT_ID_MAX=2

static bt_addr_le_t addr_broadcaster;
static bt_addr_le_t addr_connectable;

static const struct bt_le_adv_param non_connectable_adv_param = {
	.id = 0,
	.options = BT_LE_ADV_OPT_USE_NAME | BT_LE_ADV_OPT_USE_IDENTITY,
	.interval_min = 0x140,
	.interval_max = 0x190,
	.peer = NULL,
};
static const struct bt_le_adv_param connectable_adv_param = {
	.id = 1,
	.options = BT_LE_ADV_OPT_CONNECTABLE | BT_LE_ADV_OPT_USE_NAME | BT_LE_ADV_OPT_USE_IDENTITY,
	.interval_min = BT_GAP_ADV_FAST_INT_MIN_2,
	.interval_max = BT_GAP_ADV_FAST_INT_MAX_2,
	.peer = NULL,
};

void main(void)
{
    // ...
    
    err = bt_addr_le_from_str("FF:FF:FF:FF:FF:FF", "random", &addr_broadcaster);
	if (err) {
		printk("Invalid BT address: %d\n", err);
		return;
	}
	
	err = bt_addr_le_from_str("FF:AA:AA:AA:AA:FF", "random", &addr_connectable);
	if (err) {
		printk("Invalid BT address: %d\n", err);
		return;
	}
	
	bt_id_create(&addr_broadcaster, NULL); // ID 0
	bt_id_create(&addr_connectable, NULL); // ID 1
	
	// ...
}
