<p>Sends the contents of <i>data</i> to the remote device identified by <i>request</i>, and returns a new <a href="qbluetoothtransferreply.html">QBluetoothTransferReply</a> that can be used to track the request's progress. <i>data</i> must remain valid until the <a href="qbluetoothtransfermanager.html#finished">finished</a>() signal is emitted.</p>
<p>The returned <a href="qbluetoothtransferreply.html">QBluetoothTransferReply</a> object must be immediately checked for its <a href="qbluetoothtransferreply.html#error">error()</a> state. This is required in case this function detects an error during the initialization of the <a href="qbluetoothtransferreply.html">QBluetoothTransferReply</a>. In such cases <a href="qbluetoothtransferreply.html#isFinished">QBluetoothTransferReply::isFinished</a>() returns <code>true</code> as well.</p>
