Every time I boot up my XPS-13 9343 it's a 20 minute battle to get the bluetooth mouse to function. Why so difficult. Once I finally get there, the mouse works great.
I don't think there is any problem with the mouse, I think the problem is with the XPS-13. The reason I say that is that sometimes while I'm retrying the bluetooth connection, wireless will quit working on the XPS-13. When it does that, I reboot again and both wireless and bluetooth work.
