FULLNAME turn to shortname

[Chaoyue Ying]

I'm trying to design custom advertising package.The code as follow:

static void advertising_init(uint8_t type)
{
    uint32_t               err_code;
    ble_advertising_init_t init;
		ble_advdata_service_data_t self_data;

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

    init.advdata.name_type          = BLE_ADVDATA_FULL_NAME;
    init.advdata.include_appearance = true;
    init.advdata.flags              = BLE_GAP_ADV_FLAGS_LE_ONLY_GENERAL_DISC_MODE;

    init.advdata.uuids_complete.uuid_cnt = sizeof(m_adv_uuids) / sizeof(m_adv_uuids[0]);
    init.advdata.uuids_complete.p_uuids  = m_adv_uuids;
		
		add_type = type;
		self_data.service_uuid = BLE_UUID_DEVICE_INFORMATION_SERVICE;
		self_data.data.p_data = &add_type;
		self_data.data.size = sizeof(add_type);
		
		init.advdata.p_service_data_array = &self_data;
		init.advdata.service_data_count = 1;
		
    init.config.ble_adv_fast_enabled  = true;
    init.config.ble_adv_fast_interval = APP_ADV_INTERVAL;
    init.config.ble_adv_fast_timeout  = APP_ADV_DURATION;
    init.evt_handler = NULL;

    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);
}

The addtype is a global variable.

However,The raw of advertising package look like this.

The type is 0x08 and it finded in gap is BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME.

But it should be a fullname.

How should I correct it?

Hi,

You could try to  use sd_ble_gap_device_name_set() to set the complete local name of the device. It will help to set the device name in the SoftDevice, ensuring it appears correctly in advertising packets. Also, you could try to initialize advdata separately and then assign it to init.advdata.

Hi,

I resolved it.It due to the name is too long so that more than 31 words and correct automatically so that it be changed to short name even so sd_ble_gap_device_name_set() was used.

I advertise it with externed flag and I get the result as I expected.
