Apple TV Gen 2 & bluetooth speakers are not working after Sierra upgrade

[iMore Question]

After Sierra upgrade, my bluetooth speakers (Sonic Gear Pandora 3) and Apple TV Gen 2 are not working with my MacBook Pro (Retina, 13-inch, Late 2013) anymore, I cannot use these devices anymore, even though they are working fine with El Capitan, just before the upgrade. Do we expect to throw all the older devices away? May be Apple has a good relationship with the hardware vendors and want us to buy new devices supported by Sierra.....
