I have a [Dell Inspiron][1] 15R 5520 laptop. Bluetooth is not working at all.

rfkill list all gives 

0: hci0: Bluetooth

    Soft blocked: no
    Hard blocked: no

1: phy0: Wireless LAN

    Soft blocked: no
    Hard blocked: no

2: brcmwl-0: Wireless LAN

    Soft blocked: no
    Hard blocked: no

dmesg|grep -i bluetooth gives

hciconfig gives

I have visited the site http://wireless.kernel.org/en/users/Drivers/b43 and according to it

lspci -vnn -d 14e4: gives

08:00.0 Network controller [0280]: Broadcom Corporation BCM43142 802.11b/g/n [14e4:4365]

    Flags: bus master, fast devsel, latency 0, IRQ 17
    Memory at c1500000 (64-bit, non-prefetchable) [size=32K]

    Kernel driver in use: wl

So I got my PCI-ID as 14e4:4365 which it says is not supported. The alternative is wl.

What should I do?

My Wi-Fi is working normally without any problems, but Bluetooth is not working.

sudo dpkg -i wireless-bcm43142-dkms_6.20.55.19-1_amd64.deb gives following error

Could it be that your laptop's bluetooth device is attached to USB, not PCI bus? Try lsusb and see if it comes up. E.g. (on my machine): 

$ lsusb
...
Bus 001 Device 005: ID 0a5c:21e6 Broadcom Corp. BCM20702 Bluetooth 4.0 [ThinkPad]
...

You should also update BIOS first, if you have any hardware detection problems.

This will probably come as off-topic here, but I'll briefly describe how I managed to update BIOS on a Dell laptop:

  • download FreeDOS pre-built ISO image and use it to make a bootable USB drive;
  • download BIOS update from Dell support site, make sure you get the version that will run under DOS
  • boot into FreeDOS and run the BIOS update.

This bluetooth chip is not supported by kernel drivers. To get it work. it is better to report a bug at launchpad. It needs to be added to btusb driver and also you will need to convert and add firmware for that. Anyway it it can't be solved here.

Have you try this, and type in the terminal this:

 sudo apt-get install dkms
 sudo apt-get install blueman
 sudo dpkg-reconfigure Bluetooth

and it might work fine this way.
