Possible issue when more than 1 bluetooth controllers on PC #30

Hi!

I have the newest up-to date Ubuntu 15.10.
My PC has built in bluetooth controller 2.1.
I have bought also USB bluetooth controller stick 4.0 which is compatible with Your button to be able to connect with it.

Everything is working on my 1st computer where I have no built in bluetooth. So only USB bluetooth used (version 4.0). But on my 2nd computer when built in bluetooth exists (version 2.1) it does not even if I plug in USB bluetooth (version 4.0)...

$: hciconfig -a

When I do startScan no error appears:


Successfully created D-Bus connection
Successfully created D-Bus object manager
Manager: checkObjects
Manager: new adapter, 00:27:13:F3:5F:84

but clicking on the button gives nothing. Button is not scanned...

When I am checking the output of the bluetooth service it seems that only old controller is used for scanning (hci1 type 1 discovering 1 method 0 - no information about discovering by hci0) :

My thought was - hmm maybe it uses wrong controller for scan. SO I do:

sudo hciconfig hci1 down

to make down this old 2.1 controller and leave up hci0. But then when I make startScan I receive error:

Failed to start scan: GDBus.Error:org.bluez.Error.NotReady: Resource Not Ready, 36

Why it returns error when 2nd controller (bluetooth 4.0) is still up and ready for use?

    TX bytes:13775 acl:0 sco:0 commands:432 errors:0

I don't have any idea where the problem on the 2nd computer may be :/
Did I provide enough amount of information?

I'm in the same boat - I have to use bluetoothctl application, and type 'select 5C:F3:70:6D:7A:F9' to make bluetoothd use the right controller as default

I have been a bit overwhelmed the last two weeks. I will go trough all the feedback and make a new release as soon as possible!

Heh thanks. After select appropriate adapter and turn on scanning via bluetoothctl it works.

@fabianbergmark maybe the logic should be like:

allBluetoothControllers.filter( e.controllerCanHandleBluetoothVersion_4_0() ).findFirst()?

or

allBluetoothControllers.filter( e -> e.isRunning() && e.controllerCanHandleBluetoothVersion_4_0() ).findFirst()?

But as the owner of the code for sure You know better! :)
Thanks for willing to fix it!
