After many, many, many questions liker this am convinced the bluetooth feature of soundbars are not intended to be used by TVs, because TVs in general don't have BT capability. The BT portion, to me, is intended for your smartphones, like hey, there is this soundbar sitting there and when the TV is not on, can I play my smartphone on it?
Am convinced there is a hardwire connecting method between TV and soundbar, not through BT.
