Bluetooth issues on Dell Inspiron 3521 Atheros AR9485 Combo chip

Bluetooth isn't that much important to me but anyways, I don't want some components of my system to not work (it just bothers me).

So bluetooth doesn't works because Arch reports there is no bluetooth adapter found. Here are some logs to assist in this matter:

 rfkill list all
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

Output of hcitool (it's empty, no devices found)

hcitool dev
Devices:

Output of lsusb:

Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 005: ID 0c45:64ad Microdia

and finally:

sudo lsmod |grep blue
bluetooth             487424  13 btrtl,btintel,bnep,btbcm,ath3k,btusb
rfkill                 20480  7 bluetooth,dell_laptop,cfg80211
crc16                  16384  2 bluetooth,ext4

Any help in this regard will be highly appreciated. Thanks!

Re: Bluetooth issues on Dell Inspiron 3521 Atheros AR9485 Combo chip

Are you using connman for wifi? Connman can block bluetooth/wifi in mechanism different from rfkill. So if that is the case you may try "connmanctl enable bluetooth"
Have you tried "bluetoothctl", tool?

I am not using connman for WiFi. As for the bluetoothctl, same result:

[bluetooth]# list
[bluetooth]# show
No default controller available

However, AR9485 manages my bluetooth and lsusb also confirms this:
