Atheros bluetooth doesn't work anymore

Hello everyone. I have a problem with a BT device on my laptop Asus K95VJ. This laptop has WiFi + bluetooth device

[g-virus@arch-laptop ~]$ lspci | grep -i network
03:00.0 Network controller: Qualcomm Atheros AR9485 Wireless Network Adapter (rev 01)

I followed the Arch Bluetooth topic to install the required packages, the Bluetooth worked perfectly... until I have rebooted. What happened next I really no idea...

● bluetooth.service - Bluetooth service
   Loaded: loaded (/usr/lib/systemd/system/bluetooth.service; enabled; vendor preset: disabled)

Re: Atheros bluetooth doesn't work anymore

I don't have this utility because of deprecation. Should I use it?

You should always use the tool that gets the job done ;-)

Re: Atheros bluetooth doesn't work anymore

Did you check the link in my last post and do you use TLP?

Yes, I did, but I can't to find TLP config files and tools on my computer, maybe I don't use it

Re: Atheros bluetooth doesn't work anymore

How can you not know whether you're using TLP (or other, similar, power management tools)?
How did you install archlinux?

This is what typically gets you power saving, https://wiki.archlinux.org/index.php/Power_management

Re: Atheros bluetooth doesn't work anymore

Well, since I can't find any TLP utilities so I don't use it, obviously. Everything is from Arch Wiki how to install, no special changes and addons

Re: Atheros bluetooth doesn't work anymore

One more information I've found out

I just disabled bluetooth.service on autorun, and run it manually after the system will be started fully. It works. The question is why I have problems if the service enabled for autorun

Re: Atheros bluetooth doesn't work anymore

My laptop's N1535's also been quite unstable recently. Devices constantly get disconnected for some unknown reason. Tried reverting some Bluetooth-related packages and ended up with no improvement.

lsusb | grep Qualcomm
Bus 001 Device 004: ID 0cf3:e300 Qualcomm Atheros Communications

But by the way, are you also using KDE Plasma? Could this be an error of the DE?
