Trying to get Bluetooth working on Acer C720 running Debian sid.

Did you enable the bluetooth daemon at boot?

HI,

....$ /etc/init.d/bluetooth status

returns

[ok] bluetooth is running.


Which I think means the bluetooth daemon is running.

But why the patch file fails to load?

Hi all

Found a similar problem on a raspberry pi, which seemed similar so I tried this:

sudo apt-get install firmware-atheros

which did the trick, and now my Acer c720 is fully functional.
