Title:
Bluetooth devices fail to re-connect after sleep.
Status in bluez package in Ubuntu:
Confirmed
I notice similar behaviour on 20.10, Dell XPS 13 7390 2-in-1, Logitech M590
When I open Settings->Bluetooth, which takes a sec or two, something seems to
get triggered and the mouse starts working again.

Like I mentioned, the kernel drivers seem fine. It appears to be a
userspace software regression, either in bluez or in the gnome
components that call bluez. the adaptor seems dead after resuming from
sleep, until the gnome bluetooth settings panel is opened. this must
call some sort of refresh
If it's a kernel regression, please bisect the kernel:

Well, that's sort of irrelevant for those of us having this problem. I
just checked, and mine is a Broadcom BCM20702A0, so not exactly a niche
vendor. I'm especially concerned since it seems like it's just not
correctly re-scanning for bluetooth devices after waking from sleep due
to some sort of
That means the bluetooth controller really wakes up after started a
scanning.
Recent BT 4.0 controllers from Intel or Qualcomm shouldn't have this
bug.

i just had a bug for 20.10 merged into this one. note that in my case,
this just started happening since upgrading to 20.10, and it happens
with multiple different brands of bluetooth adaptor. as well, if use my
keyboard to open the bluetooth settings panel in gnome, then everything
immediately
