I have a Bluetooth dongle I had lying around.
Plugable USB Bluetooth 4.0 Low… https://www.amazon.com/dp/B009ZIILLI?ref=ppx_pop_mob_ap_share
When I connect it, it showed up in the settings. I am able to pair and connect with a Bluetooth gamepad from the Google Nexus player. It shows connected but doesn’t work.
The buttons don’t do anything. I also tried with the Shield game pad and it gave me an error when wanting to connect although it did pair. Something like input output error.
Is there something more I need to do to get it setup first?
