I have a 43" Q60A I just purchased. I cannot get it to pair with my Samsung HW-J250 Soundbar. I placed it right in front of the TV. When I look for "Bluetooth Speakers" it can't find it. I have verified the Bluetooth is working on both the TV and the Soundbar by pairing a portable JBL speaker to the TV, and pairing my cell phone to the Soundbar. The Soundbar is only 4 years old. I tried updating the firmware on the bar, following instructions to use a Fat16 formatted USB drive, but that didn't seem to work. May not matter because the last update was in 2017 which is when I got the Bar.
I can't find the specs on what Bluetooth protocol the Bar has. Any help is greatly appreciated.
