[solved]Turn on/off bluetooth hardware working in GNOME but not in KDE

I have arch with Gnome and KDE desktop.

In Gnome when i turn off Bluetooth from Settings or from nm applet, it also turn off bluetooth hardware (LED turns off too).
But on KDE desktop, if i turn off bluetooth from System Settings or from nm applet, it turn it off only at software but not the hardware (LED doesn't turn off).

Here is info about bluetooth device

[samtech@M4800 ~]$ dmesg | grep Blue

I tried to turn it on/off using hciconfig hci0 up/down and bluetoothctl's power on/off commands but all are only turning it off at software.

How do i turn off bluetooth radio at software as well as at hardware from KDE as it is doing from Gnome ?

# rfkill list

What program/applet are you using on gnome to disable bluetooth?

do it good first, it will be faster than do it twice the saint wink

Bluez and gnome-bluetooth

here is rfkill list output

From KDE - It gives same output regardless of bluetooth turned on/off from system settings.

[samtech@M4800 ~]$ rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: dell-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

From Gnome - Bluetooth turned On

[samtech@M4800 ~]$ rfkill list
0: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no
1: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: dell-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no

From Gnome - Bluetooth turned Off

[samtech@M4800 ~]$ rfkill list
1: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
2: dell-bluetooth: Bluetooth
	Soft blocked: yes
	Hard blocked: no
3: phy0: Wireless LAN

My conclusion : gnome uses soft blocking the bluetooth.
You may go back to KDE and in a console 

# rfkill block bluetooth

Then see what happen and resuming by 

# rfkill unblock bluetooth

do it good first, it will be faster than do it twice the saint wink

That's great!!
It's working!

Is there any way to tell KDE applet to run those commands when i turn on/off bluetooth from applet menu or from System Settings ?

That's a bit of reading bluedevil code. Sorry I can't help you.

No problem, i can live with it and can manually issue command when required.

Anyways, it was a great help. Thanks a lot.

I started loving Arch smile

You may write a shell script that will keep watching the bluetooth status and issue the command for you.

Ya, i will try that.
But first i need to consult wiki to know how to watch bluetooth status.

You could make a couple custom application launchers that you could click to control bluetooth. One for off and another for on, or if you want to get fancy write a script that works as a toggle. I did something similar to control cpu frequency scaling. I assume you can  add custom items to Gnome panels and KDE panels. It's been a while since I tried using Gnome3 or KDE. This solution will work regardless of desktop environment provided you can make custom items.
