[SOLVED] No bluetooth - hardware not found on ASUS laptop.

Hello guys,

After searching through the wiki, forums and externally I am yet to solve my problem, so I created yet another Bluetooth topic!

My ASUS laptop runs XFCE and WIFI works perfecly with its Qualcomm Atheros AR9462. Bluetooth does not. Packages bluez and bluez-utils are installed and I followed the instructions in the wiki.

bluetoothctl # devices (and other commands, such as power on) outputs 'No default controller available'.
btmgmt # power on outputs Set Powered for hci0 failed with status 0x11 (Invalid Index).

I have not tried to use hciconfig and hcitool, as these are now only availble from the AUR bluez-utils-compat package and their functionality is mostly replaced by bluetoothctl and btmgmt [wiki].

PC: ASUS UX32L
Kernel: 4.18.16-arch1-1-ARCH
Bluetooth hardware: (unsure) Qualcomm Atheros AR9462 Wireless Network Adapter

I have tried to disable and re-enable WIFI on BIOS as desbribed here to no avail.
My problem seems to be very similar to the one posted recently here and I have also found similar, older topics around. Sadly, none of them helped me solve my problem.

I doubt the Bluetooth hardware is faulty, as I have used it with another distro (Solus) in the past.

Any help will be much appreciated!
Cheers,

Well finally I found the solution: bluetooth was disabled in the bios...
