[Interest] Bluetooth on Qt on Pi (for real this time)

[Jason H]

I've used bluetoothctl to pair to my mac, but when I try to get local adapters on the Pi from Qt, there are none:

log:
Local Adapters:
ASSERT: "!isEmpty()" in file /usr/include/arm-linux-gnueabihf/qt5/QtCore/qlist.h, line 294


code: 
	auto localAdapters = QBluetoothLocalDevice::allDevices();
	qDebug() << "Local Adapters:";
	for (const auto &adapter: localAdapters) {
		qDebug() << adapter.address().toString() << adapter.name(); // <<pairingStatus(adapter.address());
	}

	bool result = listen(localAdapters.first().address());

Any ideas on what it takes to get it working on a Pi? When I run it on my mac, it is fine.

I'm also relatively new to BT. I've copied the chat example as close as possible. But I have _so_many_ questions.

Ultimately, I am providing a serial interface service over BT that operates some hardware on the Pi. the mac/android app will connect to it. I'm currently doing this with sockets but I don't want to require IPs or IP infrastructure.
