Hello, I have a new set of Bose QC35 that won't my pair with ubuntu 16.10 (dell xps 9550). I tried everything I could find on this mailing list (http://marc.info/?l=linux-bluetooth&m=148314289530765&w=2) and askubuntu.com (http://askubuntu.com/questions/833322/pair-bose-quietcomfort-35-with-ubuntu-16-04-over-bluetooth) but nothing seems to help. I'm trying to pair using either dual mode or bredr, as suggested in the askubunu answer. Using ControllerMode = dual I get: [bluetooth]# devices Device 04:52:C7:62:27:75 LE-Pigment Pete [bluetooth]# pair 04:52:C7:62:27:75 Attempting to pair with 04:52:C7:62:27:75 [CHG] Device 04:52:C7:62:27:75 Connected: yes Failed to pair: org.bluez.Error.AuthenticationFailed [CHG] Device 04:52:C7:62:27:75 Connected: no OnControllerMode = bredr I can't even find the device, but if remembered from the dual mode scan, I get: [bluetooth]# devices Device 04:52:C7:62:27:75 LE-Pigment Pete [bluetooth]# pair 04:52:C7:62:27:75 Attempting to pair with 04:52:C7:62:27:75 Failed to pair: org.bluez.Error.AuthenticationRejected I'm not sure what causes this or where to keep looking, as none of the questions I found online have this exact problem. Could you help guide me? -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
