Detailed Description

The QBluetoothTransferManager class transfers data to another device using Object Push Profile (OPP).

QBluetoothTransferManager uses OBEX to send put commands to remote devices. A typical OBEX transfer is initialized as follows:


  // Create a transfer manager
  QBluetoothTransferManager *transferManager = new QBluetoothTransferManager(this);

  // Create the transfer request and file to be sent
  QBluetoothAddress remoteAddress("00:11:22:33:44:55:66");
  QBluetoothTransferRequest request(remoteAddress);
  QFile *file = new QFile("testfile.txt");

  // Ask the transfer manager to send it
  QBluetoothTransferReply *reply = transferManager->put(request, file);
  if (reply->error() == QBluetoothTransferReply::NoError) {

      // Connect to the reply's signals to be informed about the status and do cleanups when done
      QObject::connect(reply, SIGNAL(finished(QBluetoothTransferReply*)),
                       this, SLOT(transferFinished(QBluetoothTransferReply*)));
      QObject::connect(reply, SIGNAL(error(QBluetoothTransferReply::TransferError)),
                       this, SLOT(error(QBluetoothTransferReply::TransferError)));
  } else {
      qWarning() << "Cannot push testfile.txt:" << reply->errorString();
  }

Note that this API is not currently supported on Android.
