Check for connections and disable bluetooth in shell

Check for connections and disable bluetooth in shell

[Jonathan Haug]

Dear bluetooth-experts,

I want to disable bluetooth on my system (via commandline), if there is
no active bluetooth connection -- without being root.

Therefor I need a way to

1.  check if there is an active bluetooth connection

2.  disable bluetooth without being root


For the second part I found

dbus-send --system --type=method_call --dest=org.bluez $(dbus-send
--system --print-reply --dest=org.bluez / org.bluez.Manager.ListAdapters
| awk -F'"' '/at/ {print $2}') org.bluez.Adapter.SetProperty
string:Powered variant:boolean:false

but this doesn't really disable bluetooth: I'm still able to deactivate
bluetooth in the panel.

For the first part I could not find a solution so far.

I'm running Ubuntu 10.04.

Thanks for your help!

'hcitool conn' can show that to you.

Just to complete this thread:

Thanks Gustavo! I'm now using the following script:

		if grep -q off-line /proc/acpi/ac_adapter/ACAD/state; then
			if !(hcitool con | grep -q "state"); then
				rfkill block bluetooth
			fi
		fi

May it be helpful for someone.
