Using

API

QLegoDevice

auto scanner = new QLegoDeviceScanner();

QObject::connect(scanner, &QLegoDeviceScanner::deviceFound, [=](QLegoDevice *device) {
  qDebug() << "Address:" << device->address();
  qDebug() << "Firmware:" << device->firmware();
  QTimer::singleShot(10000, device, &QLegoDevice::disconnect); // Disconnect after 10 seconds.
});

See examples/helloworld.cpp for a more complete example.
