CC2640 SimpleBLEobserver, issue in function parameters, unexplainable behavior at function call.

I modified the SimpleBLEObserver_addDeviceInfo() function with two more parameters as I want to store the pEvtData related to each device found.

the below function call works ok. The deviceInfo.dataLen is correctly transmitted to the function.

    case GAP_DEVICE_INFO_EVENT:
      {
        SimpleBLEObserver_addDeviceInfo(pEvent->deviceInfo.addr,
                                        pEvent->deviceInfo.addrType, pEvent->deviceInfo.rssi, pEvent->deviceInfo.dataLen, pEvent->deviceInfo.pEvtData);
      }
      break;

However if I swap the last two parameters like this

    case GAP_DEVICE_INFO_EVENT:
      {
        SimpleBLEObserver_addDeviceInfo(pEvent->deviceInfo.addr,
                                        pEvent->deviceInfo.addrType, pEvent->deviceInfo.rssi, pEvent->deviceInfo.pEvtData, pEvent->deviceInfo.dataLen);
      }
      break;

then the pEvent->deviceInfo.dataLen does not hold the original value, which is 0x1E for 30 char expected in pEvtData.

here the function I am calling

static void SimpleBLEObserver_addDeviceInfo(uint8 *pAddr, uint8 addrType, int8 addrRssi, uint8 addrDataLen, uint8 * addrData ) // $$
{
  uint8 i;
 
  // If result count not at max
  if ( scanRes < DEFAULT_MAX_SCAN_RES )
  {
    // Check if device is already in scan results
    for ( i = 0; i < scanRes; i++ )
    {
      if (memcmp(pAddr, devList[i].addr, B_ADDR_LEN) == 0)
      {
        return;
      }
    }
    
    // Add addr to scan result list
    memcpy(devList[scanRes].addr, pAddr, B_ADDR_LEN );
    devList[scanRes].addrType = addrType;
    devList[scanRes].addrRssi = addrRssi;    // $$ add rssi value to list
    memcpy( devList[scanRes].addrData, addrData, (addrDataLen > ADDR_RAW_DATA_ARRAY_SIZE ? ADDR_RAW_DATA_ARRAY_SIZE : addrDataLen)); // $$ limit buffer len to array size
    // Increment scan result count
    scanRes++;
  }
}

if I swap the last two parameters addrDataLen holds 0x64 instead of 0x1E set at calling time.

Any thoughts ?
