We have been notified already, but most kernel fixes don't come from Canonical.
It appears the problem is the 'btbcm' kernel driver. I suggest your best option is to try a newer kernel, and the best way to do that is to wait until Ubuntu 22.04 is released this weekend. Alternatively you can try newer kernel versions from https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D Probably the quickest solution however is to change to a different brand of USB Bluetooth dongle. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-hwe-5.13 in Ubuntu. https://bugs.launchpad.net/bugs/1969633 Title: Continuous Bluetooth timeouts [Broadcom BCM20702A] Status in linux-hwe-5.13 package in Ubuntu: New Bug description: My computer is an ASUS A88XM-A with AMD A8-7600 Radeon R7. Pluggable USB 2 Bluetooth dongle. Logitech K480 Bluetooth keyboard and Keychron K7 Bluetooth "keyboard". The Bluetooth manager finds the K480 but pairing always fails. The keyboard flashes blue but dongle steady blue. The K7 does not even show up. (But then the "keyboard" does not even work using a USB cable.) Bought dongle and K480 4 years ago, never got them to work at all, gave up as a bad investment. I ordered a K7 wireless keyboard. What I received was a Bluetooth keyboard. Bluetooth does not work. Plugging it in with a USB cable partially works (function keys and End key do not work). Got the K480 working with my Samsung Galaxy 5 Android tablet, but not with my computer. I want Bluetooth but do not know how to get it to work. It still does not work after 4 years of cold boots and the replacement of the power supply. I went to the Keychron Facebook Linux group. They were complaining that Ubuntu does not support Bluetooth and that the Keychron function keys do not work.
