Vendor HCI command

Question

Hi,
Iam trying to send Vendor HCI command.
Iam getting error 87 (Invalid Parameter)
Is patterns required after data?
Code snippet:
PBTH_VENDOR_SPECIFIC_COMMAND pVendorSpecificCommand;
DWORD dwSize = sizeof(BTH_VENDOR_SPECIFIC_COMMAND) + 3;
BYTE outputbuffer[254];
unsigned char data[] = {0x04, 0x04, 0x24};
pVendorSpecificCommand = (PBTH_VENDOR_SPECIFIC_COMMAND)::LocalAlloc(LPTR, dwSize);
pVendorSpecificCommand->ManufacturerId = 2;//Intel
pVendorSpecificCommand->LmpVersion = 0;//To All radios
pVendorSpecificCommand->MatchAnySinglePattern = TRUE;
pVendorSpecificCommand->HciHeader.OpCode = 0xFC00;
pVendorSpecificCommand->HciHeader.TotalParameterLength = 3;
memcpy(pVendorSpecificCommand->Data, data, 3);
DWORD dwErrCode = DeviceIoControl(hRadio, IOCTL_BTH_HCI_VENDOR_COMMAND, pVendorSpecificCommand, dwSize,outputbuffer, 254, 0, NULL); if (!dwErrCode)
dwErrCode = GetLastError();
::LocalFree(pVendorSpecificCommand);

Answer 1

I am doing the same thing but it always seems to fail with 1314 error while calling the DeviceIoControl for this IOCTL
HANDLE procToken;
  LUID luid;
  TOKEN_PRIVILEGES tp;
  OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES | TOKEN_QUERY, &procToken);
  LookupPrivilegeValue(NULL, SE_LOAD_DRIVER_NAME, &luid);
  tp.PrivilegeCount = 1;
  tp.Privileges[0].Luid = luid;
  tp.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED;
  BOOL retVal = AdjustTokenPrivileges(procToken, FALSE, &tp, sizeof(TOKEN_PRIVILEGES), (PTOKEN_PRIVILEGES) NULL, (PDWORD)NULL);
HANDLE hRadio(NULL);
 BLUETOOTH_FIND_RADIO_PARAMS frp;
 ZeroMemory(&frp, sizeof(frp));
 frp.dwSize = sizeof(frp);
 BOOL bFound = TRUE;
 HBLUETOOTH_RADIO_FIND hrf = BluetoothFindFirstRadio(&frp, &hRadio);
BluetoothFindRadioClose(hrf);
b = DeviceIoControl(hRadio, IOCTL_BTH_HCI_VENDOR_COMMAND, buffer,
   bufferLen, pResponseBuf, responseBufLen,
   &bytesReturned, NULL);
This fails with error  ERROR_PRIVILEGE_NOT_HELD
How did you solve this issue.
