Description
When you try to discover devices using the QBluetoothDeviceDiscoveryAgent you immediately get QBluetoothDeviceDiscoveryAgent::InputOutputError, after spending some hours trying to figure out what is going on, I discovered that when I switch the target sdk to API 28 it works flawless.
To reproduce the error the next code snipped is enough:
QBluetoothDeviceDiscoveryAgent *discoveryAgent = new QBluetoothDeviceDiscoveryAgent;
connect(discoveryAgent , SIGNAL(deviceDiscovered(QBluetoothDeviceInfo)),
this, SLOT(deviceDiscovered(QBluetoothDeviceInfo)));
connect(discoveryAgent , SIGNAL(error(QBluetoothDeviceDiscoveryAgent::Error)),
this, SLOT(discoveryError(QBluetoothDeviceDiscoveryAgent::Error)));
discoveryAgent->start();
