Can not pair with bluetooth headphones

[DimanNe]

I can not pair computer and Bluetooth headset (sennheiser momentum 2.0 wireless aebt).
(If it matters, I *CAN* pair and use it on another laptop with Linux and with my android smartphone. So headset itself is working well.)

Here is how I try to pair:
$ bluetoothctl
[NEW] Controller 54:27:1E:33:4B:85 impedance [default]
[bluetooth]# power on
Changing power on succeeded
[bluetooth]# agent on
Agent registered
[bluetooth]# default-agent
Default agent request successful
[bluetooth]# scan on
Discovery started
[CHG] Controller 54:27:1E:33:4B:85 Discovering: yes
[bluetooth]# scan on

I tried to put my headset in pairing mode just before and after issuing "scan on" command. It ends up with nothing - I waited for 3-5 minutes. For example, my smartphone pairs with the headset within 5-15 seconds, my laptop pairs with the headset within about 30 seconds.

Hey,

Thanks for the report. I will mark it as "needs information" because I need a follow up from your side. Once I get the log files I ask about below I will change the status to further.

- what kind of Ubuntu version is installed on the Linux computer that works just wine with your headset?

Also, could you capture a somewhat more verbose logs. I would love to see at least a HCI trace. You can capture it with sudo btmon --write ~/hcitrace.snoop. Just start it and then try to pair with your headset. Also please do not make the test case really long so that it is easier to understand the output :) Finally please read also https://wiki.ubuntu.com/DebuggingBluetooth to understand how different logs for BT debugging can be captured.

Thanks.

Konrad, the bluetooth device in this computer needs the firmware to even be able find devices while scanning. Jesse Sung made hex2hcd to convert the windows firmware with .hex filenames to something that can be used in Linux. Pilot6 wrote this http://askubuntu.com/a/632348/300665 as a general guide
