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.
Constructs a new QBluetoothTransferManager with parent.
[virtual]
QBluetoothTransferManager::~QBluetoothTransferManager()Destroys the QBluetoothTransferManager.
[signal]
void QBluetoothTransferManager::finished(QBluetoothTransferReply *reply)This signal is emitted when the transfer for reply finishes.
Sends the contents of data to the remote device identified by request, and returns a new QBluetoothTransferReply that can be used to track the request's progress. data must remain valid until the finished() signal is emitted.
The returned QBluetoothTransferReply object must be immediately checked for its error() state. This is required in case this
function detects an error during the initialization of the QBluetoothTransferReply. In such cases QBluetoothTransferReply::isFinished() returns true
as well.
If the platform does not support the Object Push profile, this function will return 0
