QT bluetooth not working on Raspberry Pi

[Avtansh Sharma]

Hi,

I ran following code on Raspbian .
Hardware:- Raspberry Pi3

#include <QCoreApplication>

#include <QBluetoothAddress>
//#include <QBluetoothLocalDevice>
#include <QDebug>
#include <qbluetoothlocaldevice.h>
int main(int argc, char *argv[])
{

QCoreApplication a(argc, argv);

QBluetoothLocalDevice aa;
aa.powerOn();
qDebug()<<"name:"<<aa.name();
qDebug()<<aa.address().toString();

qDebug()<<"hi";
}

Output is:-

name: ""
"00:00:00:00:00:00"

Did you try to get a list of all local devices with http://doc.qt.io/qt-5/qbluetoothlocaldevice.html#allDevices ?

@jsulm I tried using link

QBluetoothLocalDevice aa;
aa.powerOn();
QList<QBluetoothHostInfo> b;

b=aa.allDevices();

b had zero count. i.e QT was unable to detect any device.
