CCS/CC2640R2F: how to connect address in central

Tool/software: Code Composer Studio

hi ,

I am working  on 2640r2f board  i want to connect peripheral boards to central without prerssing key

i have did without pressing key for 1 one board now i want to  connect another board without pressing key one after one 

i have did that for both connecting but its connect address different as show below in process role event changed some

could you suggest me how connect peripherals address  to central in what condition should place before service uuid  and central address

static void SimpleBLECentral_processRoleEvent(gapCentralRoleEvent_t *pEvent)
{
    // if (scanIdx == -1)
         // {
         //   if (!scanningStarted)
         //   {
           //   scanningStarted = TRUE;
            //  scanRes = 0;


        Display_print0(dispHandle, 1, 0, Util_convertBdAddr2Str(pEvent->initDone.devAddr));

        SimpleBLECentral_startGapDiscovery();
           // }
     //     }

    // DELAY_MS(4000);

        // if filtering device discovery results based on service UUID
        if (DEFAULT_DEV_DISC_BY_SVC_UUID == TRUE)
        {
          if (SimpleBLECentral_findSvcUuid(SUNLIGHT_SERV_UUID,
                                           pEvent->deviceInfo.pEvtData,
                                           pEvent->deviceInfo.dataLen))
          {
            SimpleBLECentral_addDeviceInfo(pEvent->deviceInfo.addr,
                                           pEvent->deviceInfo.addrType);
          }
        }



        // discovery complete
     //  scanningStarted = FALSE;

        // if not filtering device discovery results based on service UUID
     // if (DEFAULT_DEV_DISC_BY_SVC_UUID == FALSE)
      //  {
          // Copy results
       //   scanRes = pEvent->discCmpl.numDevs;
        //  memcpy(devList, pEvent->discCmpl.pDevList,
          //       (sizeof(gapDevRec_t) * scanRes));
      //  }

     //   Display_print1(dispHandle, 2, 0, "Devices Found %d", scanRes);

        if (scanRes > 0)
        {



          SimpleBLECentral_connectToFirstDevice();
        }



           if (pEvent->gap.hdr.status == SUCCESS)
        {
          state = BLE_STATE_CONNECTED;
          connHandle = pEvent->linkCmpl.connectionHandle;
          procedureInProgress = TRUE;

          // If service discovery not performed initiate service discovery
          if (charHdl == 0)
          {
            Util_startClock(&startDiscClock);
          }

          Display_print0(dispHandle, 2, 0, "Connected");
          Display_print0(dispHandle, 3, 0, Util_convertBdAddr2Str(pEvent->linkCmpl.devAddr));

          SimpleBLECentral_Handler(1);


          }
        else
        {
          state = BLE_STATE_IDLE;
          connHandle = GAP_CONNHANDLE_INIT;
          discState = BLE_DISC_STATE_IDLE;

          Display_print0(dispHandle, 2, 0, "Connect Failed");
          Display_print1(dispHandle, 3, 0, "Reason: %d", pEvent->gap.hdr.status);
        }


    if(state == BLE_STATE_DISCONNECTING)
    {
        state = BLE_STATE_IDLE;
        connHandle = GAP_CONNHANDLE_INIT;
