I'm new in ubuntu.

I'm getting an error in ubuntu 14.04 in my lenovo ideapad z50-70:

dmesg | grep -i bluetooth
[   31.243849] Bluetooth: Core ver 2.17

[   39.092466] Bluetooth: Loading patch file failed

I have found a solution in askubuntu "Blacklist the ath3k module echo "blacklist ath3k" | sudo tee /etc/modprobe.d/ath3k.conf and then gksudo gedit /etc/rc.local and add modprobe ath3k above the exit 0 line, save, exit and reboot"

But it doesn't work.

Results of cat /etc/rc.local | tail -4

By default this script does nothing.

modprobe ath3k exit 0

  • Hi, please attach your lsusb output from a terminal (Ctrl + Alt + t), and update your question by editing it. – P.-H. Lin Mar 2 '15 at 7:07
  • Have you installed the package linux-firmware? And add the results of cat /etc/rc.local | tail -4 to your question – Jeremy31 Mar 2 '15 at 23:04
  • @P.-H.Lin........i have updated as per your advice – Javed Akhter Mar 3 '15 at 14:04

Edit your /etc/rc.local file and enter sleep 20 above the modprobe ath3k line and reboot

  • @Jeremy31....after editing /etc/rc.local now i'm getting the results which i updated to original question – Javed Akhter Mar 5 '15 at 15:25
  • The only thing I can think of that might cause the new error is that it might be blocked rfkill list bluetooth – Jeremy31 Mar 5 '15 at 19:24
  • @Jeremy31...yes.There is a soft block on bluetooth.How to permanently remove the softblock???? – Javed Akhter Mar 7 '15 at 4:48
  • sudo rfkill unblock all should remove all soft blocked and you might have to reboot afterwards then check rfkill list all – Jeremy31 Mar 7 '15 at 10:37
  • What kernel do you have? uname -a and what video chipset(s) do you have? It seems this issue is fixed in kernel 3.19.1 but I don't know if it will cause problems if you have anything other than intel video – Jeremy31 Mar 8 '15 at 14:45
