Hi,

Many thanks to both of you. I have migrated my code to SDK15.3, and it is working as intended now.

Regards

Hi,

How does your advertising_init() function look like ? Do you place any data in the srdata field?

In ble_app_uart example we put the UUID in the srdata like this:

static void advertising_init(void)
{
    uint32_t               err_code;
    ble_advertising_init_t init;

    memset(&init, 0, sizeof(init));

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = false;
    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_LIMITED_DISC_MODE;

    init.srdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.srdata.uuids_complete.p_uuids  = m_adv_uuids;

    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_TIMEOUT_IN_SECONDS;

    init.evt_handler = on_adv_evt;

    err_code = ble_advertising_init(&m_advertising, &init);
    APP_ERROR_CHECK(err_code);

    ble_advertising_conn_cfg_tag_set(&m_advertising, APP_BLE_CONN_CFG_TAG);
}

If you have data in srdata and doing scannable advertising, the SD will respond with the srdata to the central. You will not automatically get the event BLE_GAP_EVT_SCAN_REQ_REPORT when this happens, this is something that you need to explicitly enable, for v5.1.0, with sd_ble_opt_set(). You can e.g. put this at the end of advertising_init() function:

ble_opt_t ble_options;
memset(&ble_options, 0, sizeof(ble_options));
ble_options.gap_opt.scan_req_report.enable = 1;
err_code = sd_ble_opt_set(BLE_GAP_OPT_SCAN_REQ_REPORT, &ble_options);
APP_ERROR_CHECK(err_code);

In SDK 15.3.0, The available advertising types are in ble_gap.h:

/**@defgroup BLE_GAP_ADV_TYPES GAP Advertising types
 *
 * Advertising types defined in Bluetooth Core Specification v5.0, Vol 6, Part B, Section 4.4.2.
 *
 * The maximum advertising data length is defined by @ref BLE_GAP_ADV_SET_DATA_SIZE_MAX.
 * The maximum supported data length for an extended advertiser is defined by
 * @ref BLE_GAP_ADV_SET_DATA_SIZE_EXTENDED_MAX_SUPPORTED
 * Note that some of the advertising types do not support advertising data. Non-scannable types do not support
 * scan response data.

But the 'Advertising' module in the SDK does not allow non-connectable advertising - you have to do it "manually":

Sorry - missed your SDK version!

This is totally different in earlier SDK versions - may not be applicable to your version, 14.2
