Mr.Sigurd, sorry for the late reply.

Based on the sample program you gave me
I was able to test and get the device name.

thank you very much.

Mr. Sigurd: Thank you for your reply.
I didn't notice your reply so quickly.

I will try the program code you gave me.

thank you very much.

Hi!

Here is some code snippet that can help you find the advertising name in the advertising data.

typedef struct
{
    uint8_t * p_data;   /**< Pointer to data. */
    uint16_t  data_len; /**< Length of data. */
} data_t;

#define N_AD_TYPES 2
/**@brief Function for handling Scaning events.
 *
 * @param[in]   p_scan_evt   Scanning event.
 */
static void scan_evt_handler(scan_evt_t const * p_scan_evt)
{
    ret_code_t      err_code;
    data_t          adv_data;
    uint16_t        data_offset = 0;
    uint8_t         ad_types[N_AD_TYPES];
    uint8_t       * p_parsed_name;
    uint16_t        parsed_name_len;


    switch(p_scan_evt->scan_evt_id)
    {
        case NRF_BLE_SCAN_EVT_FILTER_MATCH:
            // Initialize advertisement report for parsing
            adv_data.p_data   = (uint8_t *)p_scan_evt->params.filter_match.p_adv_report->data.p_data;
            adv_data.data_len = p_scan_evt->params.filter_match.p_adv_report->data.len;

            ad_types[0] = BLE_GAP_AD_TYPE_SHORT_LOCAL_NAME;
            ad_types[1] = BLE_GAP_AD_TYPE_COMPLETE_LOCAL_NAME;

            for (uint8_t i = 0; (i < N_AD_TYPES) && (data_offset == 0); i++)
            {
                parsed_name_len = ble_advdata_search(adv_data.p_data, adv_data.data_len, &data_offset, ad_types[i]);
            }

            if(parsed_name_len != 0)
            {
                p_parsed_name = &adv_data.p_data[data_offset]; //The name we found
                NRF_LOG_HEXDUMP_INFO(p_parsed_name,parsed_name_len);
            }

            break;

        case NRF_BLE_SCAN_EVT_CONNECTING_ERROR:
            err_code = p_scan_evt->params.connecting_err.err_code;
            APP_ERROR_CHECK(err_code);
            break;

        default:
          break;
    }
}
