I doubt, that Ubuntu/Windows are both blocking device from connecting.
You can try to pair with your phone via BT for eg.
Seems like something else is wrong, I also tried pairing to a third device but unable to connect there earlier. For reference, all connection attempts are via Bluetooth. Would a factory reset of the device help fix this?
I have the same problem :(
anyone got a fix i have same problem with razer atheris and my adapter is lost.
