Recently bought a Logitech Triathlon M720 mouse which is lagging when connected through bluetooth.
bluetooth service is publishing following errors in journal:

Already tried this: Bluetooth - ArchWiki

Please note that the same mouse works fine when connected to a Mac or Windows.

Can someone please help me here ?

I’ve the same mouse and sometimes the same problem.
Simply switch the mouse off with the switch on the underside and then on again immediately.
For me it works fine again.

I bought this thing 5 days ago. Restarted both the computer and the mouse at least 5 times today also, still it doesn’t seem to work for me properly.
It works flawlessly after booting for 30 seconds then again starts lagging.

Do you use the included bluetooth adapter?
It’s in the battery compartment.

I tried using the unifying receiver once, it did not work for me, as the instructions mentioned in quick start manual were only meant for Mac and Windows. It mentions a shortcut which I couldn’t map in linux :
Windows : fn + P
Mac : fn + O

How do you make it work with Linux ? Does it require any special software ?

Managed to make it work with unifying receiver with Solaar.
