I'm a noob in Ubuntu. Bluetooth in my Ubuntu is not working. It was working fine in Windows but not in Ubuntu. I've searched many pages in Ubuntu forum, but none of them made bluetooth work. I think I know the problem. I'll paste it below:

anvesh@anvesh-Lenovo-G500:~$ sudo rfkill list
0: ideapad_wlan: Wireless LAN
    Soft blocked: no
    Hard blocked: no
1: ideapad_bluetooth: Bluetooth
    Soft blocked: yes
    Hard blocked: no
2: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no
3: brcmwl-0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

anvesh@anvesh-Lenovo-G500:~$ lsusb; dmesg | grep -i firmware

  • Open a terminal window with CTRL + t and copy the highlighted command lsusb; dmesg | grep -i firmware; rfkill list all; dmesg | grep -i bluetooth; uname -a; lsmod | grep bluetooth and paste into terminal with CTRL + Shift + v and you can highlight the results from terminal with your mouse/touchpad and copy with CTRL + Shift + c Edit your question to include these results – Jeremy31 Apr 25 '15 at 12:21
  • its too long to comment – lucky annu Apr 25 '15 at 12:28
  • edit to add the info or you can go to paste.ubuntu.com enter the info and post the URL you get – Jeremy31 Apr 25 '15 at 12:30
  • i think i know the problem ill paste it below show me a way to solve it anvesh@anvesh-Lenovo-G500:~$ sudo rfkill list 0: ideapad_wlan: Wireless LAN Soft blocked: no Hard blocked: no 1: ideapad_bluetooth: Bluetooth Soft blocked: yes Hard blocked: no 2: phy0: Wireless LAN Soft blocked: no Hard blocked: no 3: brcmwl-0: Wireless LAN Soft blocked: no Hard blocked: no – lucky annu Apr 25 '15 at 12:30
  • Start with rfkill unblock all Then I still will need results from lsusb; dmesg | grep -i firmware – Jeremy31 Apr 25 '15 at 12:37
  • What kernel uname -a I can get this one to work – Jeremy31 Apr 25 '15 at 12:57
  • If you do sudo update-usbids and then lsusb 105b:e065 should identify as a bluetooth device now and my answer will make it work – Jeremy31 Apr 26 '15 at 16:25

First we need to get some files

sudo apt-get install linux-headers-generic build-essential
wget https://www.dropbox.com/s/f503f6r686riiow/fw-105b_e065.hcd
echo btusb | sudo tee -a /etc/modules

If uname -a shows that you have a 3.13 kernel, then 

wget https://www.dropbox.com/s/rlv2prqzzptcr6f/bluetooth-trusty.tar.gz
tar -zxf bluetooth-trusty.tar.gz
cd bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp ~/fw-105b_e065.hcd /lib/firmware/brcm/BCM43142A0-105b-e065.hcd
sudo cp ~/fw-105b_e065.hcd /lib/firmware/
sudo modprobe btusb

If you have a 3.16 kernel 

wget https://www.dropbox.com/s/uocd0xqaprm4yvi/bluetooth.utopic.tar.gz
tar -zxf bluetooth.utopic.tar.gz
cd bluetooth
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo cp ~/fw-105b_e065.hcd /lib/firmware/brcm/BCM43142A0-105b-e065.hcd
sudo modprobe btusb

If updates happens to install a new kernel that doesn't yet support the device, you will need to do the following to get it working again

cd bluetooth
make -C /lib/modules/$(uname -r)/build M=$PWD clean
cp /boot/config-$(uname -r) .config
cp /usr/src/linux-headers-$(uname -r)/Module.symvers Module.symvers
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo modprobe -r btusb
sudo modprobe btusb

If you have a different series kernel, just add it in a comment. If you do a sudo update-usbids and look at lsusb you should notice that device with ID 105b:e065 is identified as a Broadcom BCM43142A0 Bluetooth
