Description
We have some issues with Ruptela HCV5 bluetooth-enabled device, but on top of that we can't easily handle errors as it seems that Qt ignores org.bluez.Error.AuthenticationCanceled.
Here's some relevant application output with bluetooth logging categories enabled:
qt.bluetooth.bluez: Bluez 5 detected. qt.bluetooth.bluez: Registering profile under "/qt/profile/MyApp198073/0" "e8e10f95-1a70-4b27-9ccf-02010264e9c8" qt.bluetooth.bluez: Detecting bluetoothd version qt.bluetooth.bluez: Using /proc/<pid>/exe qt.bluetooth.bluez: Using /proc/<pid>/cmdline qt.bluetooth.bluez: Detected bluetoothd version 5.55 qt.bluetooth.bluez: Bluetoothd: "5.55" qt.bluetooth: Using BlueZ LE DBus API qt.bluetooth.bluez: Creating QtBluezDiscoveryManager qt.bluetooth.bluez: Initiating discovery for pairing on "D4:B8:66:A7:C7:9E" qt.bluetooth.bluez: Sending pairing request to "D4:B8:66:A7:C7:9E" qt.bluetooth.bluez: Failed to create pairing "org.bluez.Error.AuthenticationCanceled"
I've got error and pairingFinished signals connected:
connect(m_localDevice, &QBluetoothLocalDevice::pairingFinished, this, &RuptelaBTDevice::onPairingFinished); connect(m_localDevice, &QBluetoothLocalDevice::error, this, &RuptelaBTDevice::onLocalDeviceError);
But none o these are emitted in this case for some reason.
Some other user also discovered this issue in Qt forums: https://forum.qt.io/topic/145293/bluetooth-pairing-fails
