How to use a paired bluetooth device as Smart Lock trusted device?

I am interested in using my Nexus Player (or other bluetooth device) as a Smart Lock trusted device for my phone. My goal was to be able to unlock my device without needing my usual pin while sitting on the couch. It seems like my Nexus Player (which never moves from under my TV) is a good candidate for that. When I navigate to *Settings* -> *Security* -> *Smart Lock* -> *Trusted devices* -> *Bluetooth*, I can see it listed, but not connected: " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Trusted devices not connected (Click image to enlarge) The devices are paired (but not connected): " class="img-fluid rounded" style="max-width: 100%; height: auto; margin: 10px 0;" loading="lazy"> Paired bluetooth devices (Click image to enlarge) Is there any way to use these as Smart Lock trusted devices?
