Bluetooth on Lenovo G780

Question

It's just not working. In bluetooth settings it says that bluetooth is disabled and switching it does nothing.

~$ rfkill list

~$ dmesg | grep -i bluetooth

Yes, I installed firmware for 105b:e065 and bluetooth is initializing now but still not working. Also:

~$ hcitool dev

It's blank and I can do nothing with hci.

I can get it working but I would like you to file a bug report, some info here on getting started. After my fix has been proven to work, then it can be submitted upstream. If you want, you could install Ubuntu 14.04.2 and use the fix from here — Jeremy31, May 29 '15 at 00:27

Until I can get a dkms done for this, the following will work until a kernel update

sudo apt-get install build-essential linux-headers-$(uname -r)
wget https://www.dropbox.com/s/kj6w4qkantc8sul/btusb-vivid.tar.gz
tar -zxvf btusb-vivid.tar.gz
cd btusb-2.0
make -C /lib/modules/$(uname -r)/build M=$PWD modules
sudo cp btusb.ko /lib/modules/$(uname -r)/kernel/drivers/bluetooth/
sudo modprobe -r btusb
sudo modprobe btusb

Got a dkms one done

wget https://www.dropbox.com/s/texcobck1yjvhzc/btusb-dkms_2.0_all.deb
dpkg -i btusb-dkms_2.0_all.deb

Reboot

It is quite easy to make a dkms of a single module. Look at my dkms.conf at ppa. Just change module name. If you send me a btusb file with all changes, I will post it to ppa next week. – Pilot6 May 30 '15 at 15:10
Why download link is to 2.0, but install command to 1.1? Is it a typo? – Pilot6 May 31 '15 at 09:17
@Pilot6 wrong file name originally. The only change is to include { USB_VENDOR_AND_INTERFACE_INFO(0x105b, 0xff, 0x01, 0x01), .driver_info = BTUSB_BCM_PATCHRAM }, in the device id table – Jeremy31 May 31 '15 at 12:49
I fixed it. You can push this to a ppa. Or maybe it makes sense to collect all this type of additions and add them to a custom btusb ppa. – Pilot6 May 31 '15 at 12:58
@Pilot6 I see this was already submitted http://marc.info/?l=linux-kernel&m=143205702711960&w=2 – Jeremy31 Jun 01 '15 at 09:41
That's true, but without Cc: stable@vger.kernel.org it won't reach stable Ubuntu kernels. I want to make a ppa with btusb-dkms to make it available for current users. – Pilot6 Jun 01 '15 at 09:49
