I have 2 rii i8 keyboard with built in Bluetooth who won't Connect with the xrs 4900 in the beta version,also have trouble with the Bt 200 remote if it's conncted with Bluetooth,it hangs and become unresponsive a lot,so I have unpaired it and use it in ir mode instead.
I have also tried to Connect my Sony headphones in Bluetooth and they do Connect,but if I watch live TV with they connected in the buzz 5 app the picture stutters and freeze,but if I disconnect them everthing is fine.
So maybe a issue with the Bluetooth in the software?
