thank you both. Quick last (hopefully) question: i am trying to edit the file in nano, but whe i do controlO to save and exit, it tells me "permission denied" and does not save the changes... is there anything i need to do? thanks! (it happens both when i try to edit with bluetooth on and off)

It's a system file which you'll have to edit as root. Try sudo nano.
