Comment 6 for bug 1747336

On elementary OS Loki, adding xenial-proposed and upgrading resulted in a functional bluetooth device. The upgrade did, however, upgrade a lot of packages so I just have to assume the fix is was added from this bug. All that said, it's nice to have bluetooth working. Thank you for all that you do!
