Hey there!
I am facing a very frustrating issue, where my nRF54L15 (custom board) BLE peripheral just won't appear in mobile apps.
For example, right now I am trying to set up the MCUmgr via BLE and I have everything configured but neither iOS nor Android
will show the device, be it with the nRF Connect or the Device Manager apps. Also other thirdparty BLE dev apps don't work.
When scanning with the nRF BLE Sniffer on a Mac, the peripheral instantly shows up perfectly fine. The package seems to be structured
right and at this point I don't know what else to do... I know that it can't be the hardware itself because (1) Sniffing shows valid packets going through the air, and (2) in an earlier stage, I was able to see ADVs perfectly fine with the exact same hardware, sadly I can't restore that exact code.
Below is the advertising packet in code and after that the raw bytes captured by Wireshark using the BLE sniffer.
struct bt_le_adv_param param =
BT_LE_ADV_PARAM_INIT(BT_LE_ADV_OPT_CONN, BT_GAP_ADV_FAST_INT_MIN_2,
BT_GAP_ADV_FAST_INT_MAX_2, NULL);
static const struct bt_data ad[] = {
BT_DATA_BYTES(BT_DATA_FLAGS, (BT_LE_AD_GENERAL | BT_LE_AD_NO_BREDR)),
BT_DATA_BYTES(BT_DATA_UUID128_ALL, SMP_BT_SVC_UUID_VAL),
};
static const struct bt_data sd[] = {
BT_DATA(BT_DATA_NAME_COMPLETE, CONFIG_BT_DEVICE_NAME,
sizeof(CONFIG_BT_DEVICE_NAME) - 1),
};
The LE link layer bytes.

Is anyone facing a similar experience?
