best way to connect a yaber y30 projector to a bomaker tapio1 soundbar

hi i would like to find the best way of connecting up a yaber y30 projector to a bomaker tapio1 2.0 channel soundbar the soundbar has a optical connection it has a usb connector and a 3.5mm to two rca connectors on the soundbar plus it also has bluetoothas well

apparently the yaber y30 can accept bluetooth by buying a bluetooth transmitter if this is correct can you recommend a top notch bluetooth transmitter that would give me the best sound quality from the soundbar can the soundbar and projector that i mentioned above give me full sound that way thanks marcus need to no asap thanks
