3.13.0-34 kernel

[tapiama]

I'm using this with my Lenovo Yoga 13 - works fine until I did an update today to 3.13.0-34 - and my bluetooth keyboard/mouse no longer works. I run Ubuntu. Please help! :)

Same here. Yoga 11s with kernel 3.13.0-34. The bluetooth fix does not seem to work for me. Any fix available?

[tapiama]

I found a solution, and that's to roll-back to April 28 version (ce2c77c06765ae627a3f491ef2eda807ca530faf) and build that version. It works with 3.13.0-34, and can work with latest version of rtl8723au wifi driver. rmmod + modprobe right after build+install didn't work for me for some reason, but a reboot and bluetooth comes right up.

That did the trick! Thanks so much, I haven't had bluetooth working on this machine since the day I install Ubuntu on it!

Hi all! I also confirm that the April 28 version is needed in order to get the bluetooth working with a Yoga 11s running Ubuntu 14.04, kernel 3.13.0-35-generic. The latest version loads but doesn't work.

Any idea on what got wrong on the more recent revisions?

All the best.

What branch?

I have connected to a BT mouse using the latest version from the "new" branch. BTW, this is completely new code that is merged with btusb.c. It is probably that something like this will be merged with the kernel.

Hi! Just downloaded the "new" branch. It compiled OK, but apparently there was a missing file: $ sudo make install cp: cannot stat ‘rtl8821a_fw.bin’: No such file or directory

Then, I removed the 8821 cp commands from the install target and it installed OK. After reboot it kept working! Tested with a BT file transfer.

Regarding my previous message about the April 28 version, I believe it was the master branch, I've got it from here: https://github.com/lwfinger/rtl8723au_bt/tree/ce2c77c06765ae627a3f491ef2eda807ca530faf

Thanks again, all the best.

[lwfinger]

Thank you for the feedback. That file is now added to the repo.

[rpseng]

Nice! I guess you also need to add rtl8761a_fw.bin.

I have a Lenovo Yogapad 13' running Elementary OS Freya (Ubuntu 14.04). This driver used to work fine until the kernel update. However, I can confirm that a roll back to April 26th of rtk_btusb.c works on 3.13.0-36 after a reboot.

Another confirmation that rolling rtk_btusb.c back to the state it was in on April 26th fixes Bluetooth on the Lenovo Yoga 13 (original). Just don't forget to restart the machine after running sudo make install.

FYI, there is a new 'kernel' branch that has code that will be in kernel 3.21. It handles the Realtek devices just like any other kernel device. Thus far, no changes for older kernels have been included. As problems are reported, I will fix them.
