Public bug reported:
https://askubuntu.com/questions/957071/atheros-ar9285-bluetooth-dual-
mode-not-working-on-lubuntu-16-04
Everything can be found on this link. Anyway, I make a hardcopy about
it.
My problem is that I have a AR9285 bluetooth + wifi card in a HP probook
4330s. I tried several methods from the internet, still not working the
bluetooth dual mode.
Enabling the btcoex=1
Main symptomps: first after boot the bluetooth.service is in halt state.
After restart I can start the bluetooth manager. But When I open, I
can't connect to any devices and it drops there is no bluetooth
adapters.
here is the outputs.

hcitool dev doesn't drop any kind of adapters. When I plug a custom BT
adapter, drops back a device handler for this.
In my opinion the correct device descriptor is missing from the ath9k
driver.
EDIT1:
Removed ath9k.conf
I tried:
modprobe -rfv ath9k
modprobe ath9k btcoex_enable=1
