Bluetooth module is 'working' but doesn't detect any device at all. I installed https://github.com/lwfinger/rtlwifi_new, and rtl8723au_bt-kernel Then i followed Pilot6's instructions in this post: RTL8723BE Bluetooth does not work and finally got everything installed, but still nothing is detected. Maybe i should have uninstalled the first drivers before installing Pilot6's ones? Also i couldn't download rtl8723au-bt-dkms using apt-get, i had to download the .deb from the web and run the installer. Please help me, i don't know what else to do.

This specific device is not known to Linux kernel yet. But it is not a big problem. I can add it there.

You need to create a bug report by running

ubuntu-bug linux

in terminal.

Follow directions to create the report and post the output of

usb-devices | awk '/13d3/' RS=

to the bug description in addition to an explanation of the bug.

When you create the report, post a link to it here.

I will build a test module that should enable bluetooth for you. If it works well, I will send a patch to kernel maintainers and post a workaround here.
