My 6.0.1 Tablet seems to have fully-functioning Bluetooth, yet it does not "see" my new Viper VTooth Dartboard. My BB Classic detects it, so the dartboard appears to be working, but the phone is not compatible. I've seen various issues reported around the internet about Bluetooth dropping off after upgrading from Lollipop to Marshmallow. I'm wondering if I should try to downgrade my tablet to 5 from 6, and would like input from anyone experienced in this area. Thanks in advance.
