I am struggling with making bluetooth scanner demo work for linux. I have
installed BlueZ on my Ubuntu virtual machine via
sudo apt-get install libbluetooth-dev
But when I run the btscanner demo, the 'scan' button comes out disabled. I
don't get any warnings or errors but I can never scan.I have also tried the
following code in separate project but it doesn't find any bluetooth
devices.
void MyClass::startDeviceDiscovery(){
// Create a discovery agent and connect to its signals
QBluetoothDeviceDiscoveryAgent *discoveryAgent = new
QBluetoothDeviceDiscoveryAgent(this);
connect(discoveryAgent, SIGNAL(deviceDiscovered(QBluetoothDeviceInfo)),
this, SLOT(deviceDiscovered(QBluetoothDeviceInfo)));
// Start a discovery
discoveryAgent->start();
//...}
// In your local slot, read information about the found devicesvoid
MyClass::deviceDiscovered(const QBluetoothDeviceInfo &device){
qDebug() << "Found new device:" << device.name() << '(' <<
device.address().toString() << ')';}
My question is how can I make bluetooth work for linux? How do I wire up Qt
to use BlueZ? I hear about Qdbus as well but I don't know exactly how does
that fit in the picture since the demos don't seem to use it.
I am using Ubuntu 4.04 and BlueZ version 4.11 which I believe is supported
by Qt. I am new to linux world though.
Any tips would be greatly appreciated. Thanks
