    Ubuntu can't see my bluetooth hardware

    Hi folks.

    I bought a mini pci-e card (combo Wifi and bluetooth) for my laptop SAMSUNG r469

    name of the card
    Code:
    lspci -nn | grep -i netw
    02:00.0 Network controller [0280]: Intel Corporation Centrino Wireless-N 2230 [8086:0887] (rev 71)
    The Wireless-N 2230 must contain the bluetooth 4.0, but I cant see.

    Code:
    igor@R469:~$ rfkill list all
    0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
    Here some info from dmesg

    Re: Ubuntu can't see my bluetooth hardware

    Was this card designed to work with this laptop? If not, the bluetooth may not work as part of this Intel card. It may not be supported by the motherboard chipset.

    FYI, it appears that this laptop had an option for bluetooth support. A clue here:

    https://sites.google.com/site/driver...river-notebook

    in that a Broadcom bluetooth driver (for XP) is offered, and only Atheros and Realtek WiFi card drivers are offered.

    It's possible you can add a separate bluetooth card somewhere on the motherboard. I have done this on a couple of Dell laptops, where there was a place to plug it in - very easy to add. Sometimes bluetooth is an option that isn't practical because the motherboard doesn't have a socket soldered on for it, even though some versions of the computer were sold with that option.

    Of course, you can buy a cheap USB bluetooth dongle (for under $2 USD), but they are still a bit annoying plugged into your USB port.
