Import data from Scubapro Aladin Sport Matrix

[Berthold Stoeger]

Dear all,

I'm trying to import dive logs from a Scubapro Aladin Sport Matrix according to the 
manual. This is on Kubuntu 17.04 and subsurface compiled from source.

Pairing with bluetoothctl works as described, with the exception that I have to remove the 
device before pairing. Nevertheless, import fails. In qt-ble.cpp, l. 449 the 
"connectToDevice()" call returns immediately with the following console output:
> qt.bluetooth.bluez: Unknown l2cp socket error: 
> QBluetoothSocket::UnknownSocketError "Device or resource busy"
> qt.bluetooth.bluez: No settings found for peer device.
More details at the end of this mail.

Googling for the l2cp socket error I only found this:
https://bugreports.qt.io/browse/QTBUG-55150

I tried disconnecting after pairing in bluetoothctl, but this actually interrupts the 
connection and leads to a different failure mode.

Does that mean I have to wait for Kubuntu to ship with recent Qt? :(

Thank you,

Berthold
