I do not know whether or not this might be relevant, but my Panasonic TV can only be a "receiver" for bluetooth, or a "sender". It cannot be both at the same time, and when I once had the patience to search the depths of the settings, it told me that when I switched it, it would only switch back if I again spent good drinking time in the depths of the menu.
Whatever I was trying to do, I decided that life was too short, so I gave up.
