[Bug 1872122] Re: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) Subsystem [8086:0034] Kernel 4.19+: Bluetooth not working; Ubuntu 20.04
I am receiving a similar error with my Microsoft Surface bluetooth mouse after upgrading to the latest kernel.

That indicates it is a problem with the kernel, doesn't it? The desired behaviour exists in previous versions but is broken in current versions where the only component changing is the kernel version. I too am seeing this and specifically with the AC 9560's Bluetooth's BLE on a 4.19 kernel - I am unable to scan or query any BLE devices with this hw and kernel now. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872122 Title: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) Subsystem [8086:0034] Kernel 4.19+: Bluetooth not working; Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872122/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So it doesn't seem to be an issue in kernel. If you think there is still something wrong in the software (bluez?), please add the affected projects. ** Changed in: linux (Ubuntu) Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872122 Title: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) Subsystem [8086:0034] Kernel 4.19+: Bluetooth not working; Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872122/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

So, the main problem has been identified: In kernel v < 4.19 the "normal" BLE commands work. In kernel v > 4.19 only the BLE extended (BT 5.0) commands work. When software relies on the "normal" BLE commands, issues arise when kernel v > 4.19 is being used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872122 Title: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) Subsystem [8086:0034] Kernel 4.19+: Bluetooth not working; Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872122/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

First, hcitool has been deprecated for a long time. Please use btmgmt instead. Second, please do a complete shutdown, unplug power cable for a while and power on. Attach system journal log of this boot for it will contain firmware loading information that is necessary to take further investigation. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1872122 Title: Intel Corporation Cannon Point-LP CNVi [Wireless-AC] [8086:9df0] (rev 30) Subsystem [8086:0034] Kernel 4.19+: Bluetooth not working; Ubuntu 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1872122/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
