I am experiencing the same problem outlined in this question, a laggy Bluetooth mouse (Logitech MX Anywhere 2S). It seems a common solution is to edit /var/lib/bluetooth/<device id>/<peripheral id>/info and change the ConnectionParameters.Latency to 0.

When I try this with Fedora 35 (kernel 5.15), the values revert back to their original state after a few minutes and the mouse remains laggy.

What is overwriting these values in Fedora? Is there a proper way to change Bluetooth mouse latency, perhaps with the bluetoothctl tool?

Maybe a custom udev rule? – Aaron D. Marasco Jan 11 '22 at 23:45
Thanks, but this is a fresh install. `/etc/udev/rules.d/` is empty. – drs Jan 12 '22 at 03:20
I meant maybe you could write up a new rule "when you see this device, do this." – Aaron D. Marasco Jan 12 '22 at 21:14
You can try editing some values under `[LE]` in `/etc/bluetooth/main.conf`, e.g. `ConnectionLatency=`. I'd post this as an answer, but in my very quick test it didn't work. Maybe you have better luck if you try unpairing and then repairing the device. – Denilson Sá Maia Jul 25 '22 at 09:02
