Qt Bluetooth query when running on Linux with BlueZ
-
Hi,
I am using Qt5.4.1 on Linux with BlueZ4.101
When trying to connect to another slave device, I have following queries:
- How does pairing happen ? I don't have agent running but still requestPairing(QBluetoothAddress(address), QBluetoothLocalDevice::AuthorizedPaired) succeeds.
- I get following log during pairing:
qt.bluetooth.bluez: OrgBluezDeviceInterface* getDevice(const QBluetoothAddress&, QBluetoothLocalDevicePrivate*) reply failed QDBusError("org.bluez.Error.DoesNotExist", "Does Not Exist")
I enabled logging in my app and here are the logs:
qt.bluetooth.bluez: Bluez 4 detected.
