Send data using QBluetooth

[Mihaill]

Hi!
My PC (Ubuntu 20) connected o Bluetooth, I can get address and try listen QBluetoothServer:

    QBluetoothLocalDevice device;
    connect(m_bluetoothServer, &QBluetoothServer::newConnection, this, [](){qDebug()<<"wwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww";});
    if (device.connectedDevices().length()) {
        m_bluetoothServer->listen(device.connectedDevices()[0]);
    }

How I can send data "10000000-0000-0000-0000-000000000000" on service "{99999999-9999-c8c8-c8c8-d2d2d22d2d2d}" ?
