Hello!
Apparently, this is an issue with blueman. the bluetooth manager. This issue has been affecting all the different versions of Ubuntu for the last couple of versions now.
It turns out that the person who wrote blueman had disabled discovery, because pulseaudio was having issues at the time. Pulseaudio has since been fixed, and an updated version of blueman is available through a PPA. Once one updates blueman, everything works as it should.
I am in the process of writing a step-by-step tutorial on how to make fix things to make Bluetooth work in Linux Lite 2.0. I should have it posted within a day or two.
One of the things I must do to test it is to follow the procedure on a laptop that I haven't done anything to install Bluetooth on yet. If the powers that be like it, perhaps it will become part of the manual, and I'm sure that at some point, an updated version of blueman will be included in a future update.
Additionally, at some point, Ubuntu will update their repositories. The problem with the repositories is that it can take a while for updates to be added...
