Qualcomm Atheros Communications AR3011 USB 0cf3:3005 Bluetooth headset stopped connecting

[Александр]

1. expected to connect the stereo headset via Bluetooth as usual.
2. Headset stopped connecting
3. Updated again, checked the headset on Android. It works on Android, but not in Ubuntu. - after a recent system update (1-3 years ago), the stereo headset stopped connecting.

Syslog has:

  bluetoothd[901]: Failed to set mode: Blocked through rfkill (0x12)

Can you execute `rfkill list` and paste the result? You may want to try `rfkill unblock all` if you find anything listed as blocked.

[You-Sheng Yang (vicamo)]

I was wrong. You're referring to AR3011 connected to usb bus. But please still try the rfkill command above.
