Bluetooth bug : Failed to pair

Postby freenestor » 2015-10-14 19:17


Context :
I have a Thinkpad X201 with Debian 8 LXDE. Cf.
I installed blueman and blueman-applet for systray
I have a Sony wireless keyboard (model N° CECH-ZKB1FR). Cf. (this one is for Great Britain) : ... NL_vf1.pdf

Prolem :
When I add the keyboard via blueman-applet, I can detect it, but when I try to connect, I have this message : "Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken."

Investigation :
I had a look at
I use bluetoothctl (bluetooth-agent does not work, which i do not know why).

me@think:~$ bluetoothctl
[NEW] Controller E0:2A:82:F2:9F:BD think [default]
[NEW] Device 74:2F:68:AB:D1:CA Wireless Keyboard
[bluetooth]# pair 74:2F:68:AB:D1:CA
Attempting to pair with 74:2F:68:AB:D1:CA
[CHG] Device 74:2F:68:AB:D1:CA Connected: yes (I typed the code on wireless keyboard just after "Connected: yes" - EDIT : I am sure it is the good one)
Failed to pair: org.bluez.Error.AuthenticationFailed
[CHG] Device 74:2F:68:AB:D1:CA Connected: no

Thanks for your help,

Several people have the same problem on this thread :
One says " Problem is coming with kernel 3.2.0-24-generic-pae but not with kernel 3.2.0-23-generic-pae ". My own kernel is 3.16.0-4-amd64. Do I necessarily have to upgrade or is the solution elsewhere ? e.g. ... 4#p1469064 says the problem is in the btusb module.I want to stay on Debian stable and I really do not want to break my install...

Thanks for your help,
