Bluetooth Simultaneous Scanning and Non-Connectable Advertising using Identity not allowed?

[prathje]

I am trying to simultaneously scan and advertise (non-connectable) using the identity in both cases.
However, I am not able to start advertisements as the config is reported as invalid.
Apparently, the following line prevents the start of advertisements:

zephyr/subsys/bluetooth/host/id.c

Line 571 in 5130db3

(param->options & BT_LE_ADV_OPT_USE_IDENTITY)) {

I am currently unsure if this behavior is intentional, and I am misusing the identity configuration or if this line should actually be changed to: !(param->options & BT_LE_ADV_OPT_USE_IDENTITY) as the identity case should indeed not set a NRPA (as the comment claims).

Some clarification would be greatly appreciated, thanks.

I am using the following config and code:

CONFIG_BT_PRIVACY=n
CONFIG_BT_EXT_ADV=n
CONFIG_BT_SCAN_WITH_IDENTITY=y

struct bt_le_scan_param scan_param = {
            .type       = BT_LE_SCAN_TYPE_PASSIVE,
            .options    = BT_LE_ADV_OPT_ONE_TIME,
            .interval   = 0x0010,    // TODO: Adapt interval and window
            .window     = 0x0010,
    };

    int err = bt_le_scan_start(&scan_param, device_found_cb);
struct bt_data ad[] = {
            BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
            ...
    };
   
   err =  bt_le_adv_start(
         BT_LE_ADV_PARAM(BT_LE_ADV_OPT_NONE | BT_LE_ADV_OPT_USE_IDENTITY,
                 BT_GAP_ADV_FAST_INT_MIN_2,
                 BT_GAP_ADV_FAST_INT_MAX_2,
                 NULL),
         ad,
         ARRAY_SIZE(ad), NULL, 0);
