I start a scan BT_DEVICE::BT_DEVICE() { discoveryAgent = new QBluetoothDeviceDiscoveryAgent(); discoveryAgent->setLowEnergyDiscoveryTimeout(5000); connect(discoveryAgent, &QBluetoothDeviceDiscoveryAgent::deviceDiscovered, this, &BT_DEVICE::AddDevice); connect(discoveryAgent, &QBluetoothDeviceDiscoveryAgent::finished, this, &BT_DEVICE::ScanFinished); } void BT_DEVICE::BLE_Scan() { qDeleteAll(devices); devices.clear(); discoveryAgent->start(QBluetoothDeviceDiscoveryAgent::LowEnergyMethod); if (discoveryAgent->isActive()) { m_deviceScanState = true; } } Then on deviceDiscovered event I add my remote device to a list void BT_DEVICE::AddDevice(const QBluetoothDeviceInfo &info) { if (info.coreConfigurations() & QBluetoothDeviceInfo::LowEnergyCoreConfiguration) { auto d = new DeviceInfo(info); if (d->getName() == "MyDeviceName") devices.append(d); } } Finally on finished event void BT_DEVICE::ScanFinished() { QVariant dev_list = QVariant::fromValue(devices); } But what actually is finished ? Remote devices sends beacons constantly, so as for me it never finished. I should scan it constantly.

I think 32-bit version will run

No it will not. RaspberryPi is ARM, not x86...

I see. Any forecast when a newer version will be available for RaspberryPi ?

@jenya7 This is something you have to ask Debian.
