Trying to get my BCM 43142 card's bluetooth to work on Lenovo z50. I followed instructions from this forum to install the akmod-wl to get the wifi working. But I am not able to get bluetooth working.

When I go to Settings -> Bluetooth, it says Bluetooth is disabled.

uname -r

Output from lspci

$ lspci | grep BCM
lspci -v | grep BCM
02:00.0 Network controller: Broadcom Corporation BCM43142 802.11b/g/n (rev 01)

rfkill says

$ rfkill list bluetooth
2: ideapad_bluetooth: Bluetooth
   Soft blocked: yes
   Hard blocked: no
$ rfkill unblock bluetooth
$ rfkill list bluetooth
2: ideapad_bluetooth: Bluetooth
   Soft blocked: no
   Hard blocked: no

Output from hciconfig and hcitool

$ hciconfig 
$ hcitool dev

Same here, but I have a Lenovo G510.

@cx0der - Does it get detected by bluedevil?

abadrinath gravatar imageabadrinath ( 2014-08-24 04:35:46 -0500 )edit

is there a directory /var/lib/bluetooth/

I installed Bluedevil, still no luck. When I run bluedevil-monolith and click on the icon, it says no adapter found.

/var/lib/bluetooth directory is present, but empty

OK, so bluetooth card is not detected.

See if this fixes it:

sudo yum install bluez-hid2hci
sudo systemctl restart bluetooth.service

I had the same problem in a Dell Inspiron 11 3000, with the same bluetooth / wifi chip. Here's how I solved it in Fedora 25:

I hope it helps.

I have this problem too. I resolved it some time ago on Ubuntu, but have no time/not enough patience to configure it on Fedora too.

It is (probably) caused by lack of Bluetooth firmware (approriate information you will find in dmesg). Unfortunately, in most tutorials/to-do which I found over the Internet, most people suggest to copy firmware from Windows machine for example here.. Some of them pack firmware, for example here.

Anyway, I think that you need to find binary with firmware, copy it to /lib/firmware/brcm/ and then restart system. Please let us know if you have succeed, and write step-by-step tutorial :-)
