I would like to see bluetooth devices over my computer. I have a Asus x79 Deluxe which supports Bluetooth 4.0. It would be nice if that worked under Linux.

I have installed the following packages:

  • bluez-utils
  • libopenobex1

I have blueman installed and clicked on "turn bluetooth on". After that, when I click on devices it does not see any. When I click on "Adapters" I get an empty popup.

What is the problem and how can I further investigate it / solve it?

My System

$ sudo hcitool scan

I am not sure, but I think the WLAN chipset BCM4352 is also the part that handles bluetooth.

I am afraid BCM4352 is not supported by current Linux kernel's b43 driver. I would suggest trying Dell's or Broadcom's proprietary drivers instead, see also this answer for same problem on an older version of Ubuntu.

If they provide a .deb package for Ubuntu 14, you'll likely be able to see the device with blueman and use it.

NOTE: it will affect your wifi functionality as well

    I have seen that page. However, I have enabled a proprietary driver and WLAN seems to work. What does the wl in the column "alternative" mean? – Martin Thoma Sep 26 '14 at 13:30
  • And what does "PHY" mean on that page (in the table header row). – Martin Thoma Sep 26 '14 at 13:37
  • "PHY" is the radio chipset, see also the Wikipedia page – Deim0s Sep 26 '14 at 13:43
  • "wl" is just another wireless driver in Linux, but is not alternative to yours as you can see from that table, there's no point in trying it. You say that you have enabled a proprietary driver, but this is not what I said in the answer. You need to use the one provided by vendor (Dell/Broadcom/Asus...), if there's any available. Your chipset is not yet supported natively. So yes, it will be difficult to make it work. – Deim0s Sep 26 '14 at 13:45
