Hi, hopefully this is the right list (please don't blame me if not :) It seems it is no more possible to pair with Genius Navigator 900 Pro mouse. It seems it's older mouse probably with no SSP/ built-in PIN. # bluetoothctl [bluetooth]# pair ADDR [CHG] Device ADDR Connected: yes [CHG] Device ADDR Connected: no [CHG] Device ADDR Connected: yes Failed to pair: org.bluez.Error.AuthenticationRejected [CHG] Device ADDR Connected: no Hcitool "trick": # hcitool cc ADDR;hcitool auth ADDR HCI authentication request failed: Input/output error The above error is shown before the PIN dialog appears. I also tried Blueman GUI, but it tracebacks (report also sent). Moreover: # hciconfig hci0 sspmode 0 Can't set Simple Pairing mode on hci0: Input/output error (5) So I cannot try without SSP. It seems there is nothing related in dmesg. IIRC the mouse worked in the past. $ uname -r 4.5.7-200.fc23.x86_64 OS: Fedora 23 userspace: bluez-5.39 machine: Lenovo ThinkPad X240 adapter probably: Intel Centrino 7260 2 x 2 AC+ BT 4.0 module: btintel: Intel Bluetooth firmware file: intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq Could you advice some other tricks how to get it working? I could also bisect the problem later thanks & regards Jaroslav -- 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
