Bluetooth Digital output to Lexicon MC-1 Pre-Pro

I just purchased a Sharp Aquos 75" Smart TV (Made by Hisense) and am trying to connect it to my Lexicon pre-pro.  It does have optical digital out, but it's having trouble recognizing the Lexicon. I wanted to know if the Bluetooth output is an option.  I know I would have to buy a receiver, but don't want to do that unless I know the bluetooth output is fully Dolby Digital capabable, or it it's a special format intended only for sound bars.

Sharp Technical support and the manual are useless.

Can anyone advise?  thanks in advance.
