Public bug reported: For kernel version >= @TO_BE_FILLED@, it fails to pair with BT4.0 HID devices and leave error messages in syslog:
Bluetooth: hci0: request failed to create LE connection: status 0x0c Which can be detailed by btmon: < HCI Command: LE Extended Create Connection (0x08|0x0043) plen 26 #800 [hci0] 30.895622 Filter policy: White list is not used (0x00) Own address type: Public (0x00) Peer address type: Random (0x01) Peer address: DB:DD:51:2D:1C:CC (Static) Initiating PHYs: 0x01 Entry 0: LE 1M Scan interval: 60.000 msec (0x0060) Scan window: 60.000 msec (0x0060) Min connection interval: 30.00 msec (0x0018) Max connection interval: 50.00 msec (0x0028) Connection latency: 0 (0x0000) Supervision timeout: 420 msec (0x002a) Min connection length: 0.000 msec (0x0000) Max connection length: 0.000 msec (0x0000) > HCI Event: Command Status (0x0f) plen 4 #801 [hci0] 30.896453 LE Extended Create Connection (0x08|0x0043) ncmd 1 Status: Command Disallowed (0x0c) Indicating this is actually a firmware problem. Verified this has been fixed at least in upstream linux-firmware commit 29a536a02cadb75b84c6c0b5d7af22d34d278563, firmware release version 21.10.0.6. With that firmware blob placed under /lib/firmware/intel and a cold boot, dmesg gives updated revision and device pairing works as expected: Firmware revision 0.1 build 184 week 15 2019 ** Affects: linux-firmware (Ubuntu) Importance: Undecided Assignee: You-Sheng Yang (vicamo) Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1829737 Title: Bluetooth: hci0: request failed to create LE connection: status 0x0c (Intel 9462/9560) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1829737/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
