Hi ,

I use nRF connect app to create an advertisement.

But this device cannot be scanned using cc2640r2f.(phone and PC can scan it)

What settings do I need to modify?

SDK:cc2640r2_sdk_1_40_00_45

Please refer to the following for scan code.

GAP_DEVICE_INFO_EVENT.txt

    case GAP_DEVICE_INFO_EVENT:
    {

#ifdef DEV_DISC_BY_SVC_UUID
      //if(str_cmp(addrBuf,pEvent->deviceInfo.addr,6)==1)
      //if(pEvent->deviceInfo.addrType==0x00)
      if(pEvent->deviceInfo.addrType==0x00 || 0x01 || 0x02 || 0x03)
      {
          //if ( simpleBLEFindSvcUuid( WANTED_SERVICE_UUID,
          //                           pEvent->deviceInfo.pEvtData,
          //                           pEvent->deviceInfo.dataLen ) )
          //{
            //simpleBLEAddDeviceInfo( pEvent->deviceInfo.addr, pEvent->deviceInfo.addrType );
            
            scanIndexID++;
            TLwrite(&pEvent->deviceInfo.addrType,1);
            SerialPrintString("\r\n");
            memcpy(addrBuf, pEvent->deviceInfo.addr, 6);
            memcpy(devList[scanIndexID-1].addr, pEvent->deviceInfo.addr, B_ADDR_LEN);
            devList[scanIndexID-1].rssi = pEvent->deviceInfo.rssi;
            devList[scanIndexID-1].addrType = pEvent->deviceInfo.addrType;
            // Convert address to string
            uint8_t *pAddr = (uint8_t*)Util_convertBdAddr2Str(pEvent->deviceInfo.addr);

            // Copy converted string to static device list
            memcpy(devList[scanIndexID-1].strAddr, pAddr, B_STR_ADDR_LEN);
            
          //}
      }
      else
      {
        
        if(pEvent->deviceInfo.eventType==0x04)
        {    
            devList[scanIndexID-1].eventType = pEvent->deviceInfo.eventType;
#ifndef TRANSPARENT               
            memcpy(devList[scanIndexID-1].advBuf, pEvent->deviceInfo.pEvtData, pEvent->deviceInfo.dataLen);  
#endif            
        }
        
        
      }

Thanks.

Hello,

I tried this out using SDK v1.50 (the oldest I had on hand at the moment). I was able to discover my iPhone 11 using both BTOOL and the simple_central example.

I simplified the logic of the GAP_DEVICE_INFO_EVENT as follows:

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

You should also ensure DEFAULT_DEV_DISC_BY_SVC_UUID is set to FALSE. If your device is not discovered in the first DEFAULT_MAX_SCAN_RES advertisements, you will have to retrigger the scan. Setting DEFAULT_MAX_SCAN_RES to a larger amount allows more scan results with a higher likelyhood your advertisement is received, so do try this too.

Hi Ammar,

I use SDK v1.50 and it can work fine.

Thanks.
