However getting all the right parts, cables and such can be troublesome. However from Samsung's own site I read
" Stereo port for media players, cameras, and other devices to run audio into or out of the TV. " which is in the mini jack noted at

OK, let's say we use that jack, a simple Y audio splitter so you can connect your bluetooth transmitter and the soundbar? writes it can accept such via the soundbar's AUX IN "Connect to the Analog output of an external device" so it appears possible to set it all up.

Here's the Y cable and keep in mind many folk will have to have a service call to sort it all out.
