LP-EM-CC2340R5: How does the Central display peripheral names during scanning?

Tool/software:

Hi Ti team,

When CC2340R5 (Central mode) is scanning for Bluetooth devices, why can't it detect the names and signal strengths of Peripherals? However, the smartphone app (simplink) can display the names and signal strengths of Peripherals during scanning.

void Central_ScanEventHandler(uint32 event, BLEAppUtil_msgHdr_t *pMsgData)
{
    BLEAppUtil_ScanEventData_t *scanMsg = (BLEAppUtil_ScanEventData_t *)pMsgData;

    switch (event)
    {
        case BLEAPPUTIL_SCAN_ENABLED:
        {
            centralScanIndex = 0;
            MenuModule_printf(APP_MENU_SCAN_EVENT, 0, "Scan status: Scan started...");

            break;
        }

        case BLEAPPUTIL_SCAN_DISABLED:
        {
            uint8 i;

            for(i = 0; i < APP_MAX_NUM_OF_ADV_REPORTS; i++)
            {
                memset(&centralScanRes[i], 0, sizeof(App_scanResults));
            }

            // Go over the advertise reports that was saved in the host level and save it
            for (i = 0; i < scanMsg->pBuf->pScanDis.numReport; i++)
            {
              GapScan_Evt_AdvRpt_t advReport;
              // Get the address from the report
              GapScan_getAdvReport(i, &advReport);

              memcpy(watchchar[i],advReport.pData,advReport.dataLen);
              // Add the report to the scan list
              Central_addScanRes(&advReport);


            }
            UART2_write(uart, (const char *)"scan finish !!!\r\n\r\n", strlen((const char *)"scan finish !!!\r\n\r\n"), NULL);

            MenuModule_printf(APP_MENU_SCAN_EVENT, 0, "Scan status: Scan disabled - "
                              "Reason: " MENU_MODULE_COLOR_YELLOW "%d " MENU_MODULE_COLOR_RESET
                              "Num results: " MENU_MODULE_COLOR_YELLOW "%d " MENU_MODULE_COLOR_RESET,
                              scanMsg->pBuf->pScanDis.reason,
                              scanMsg->pBuf->pScanDis.numReport);
            break;
        }

advReport.pData = 0   advReport.dataLen = 0

memcpy(watchchar[i],advReport.pData,advReport.dataLen);
