https://bugzilla.kernel.org/show_bug.cgi?id=201363 --- Comment #1 from Samantha McVey (samantham@xxxxxxxxxx) --- Created attachment 279011 --> https://bugzilla.kernel.org/attachment.cgi?id=279011&action=edit dmesg with bluetooth Update: I have extracted Lenovo's RTL8822BE wifi and bluetooth firmware from their Windows driver packages and gotten the bluetooth partially working. It works if the system is up to sleep and then woken up again, though it doesn't work when the system is booted up for the first time. lsusb info: Bus 004 Device 008: ID 0bda:b023 Realtek Semiconductor Corp. I am hosting the firmware here https://github.com/samcv/A485-RTL8822BE-firmware which has detail about how I extracted the firmware so I will only repost relevant info here. So there is still an issue loading firmware at boot, which hopefully makes this issue easier to solve.
