What you see is that we start connecting with the default values and then the slave (the mouse) will correct us and tell us what connection parameters it needs. We accept them and actually change the LE link to use these parameters. However we end up forgetting them. So every time you connect this procedure keeps repeating itself. >>> >>> I fixed this as well, but for that you will need a bluetooth-next kernel where I enabled the management API for passive scanning and a modified bluetoothd that will then allow you a smooth experience. If the slave updates the connection parameters we remember them for devices using auto-connection. So once the connection is triggered via passive scanning the values will be remembered. >>> >>> At the moment, I have one minor issue with the re-connection within bluetoothd and once that is fixed this should be pretty instant. >> >> >> Okay, great, glad to hear that you're already on it.

I had to merge with rc3 because rc1 wouldn't boot on my machine for some other reason. At first I had rfkill soft blocked when resuming from standby but then I pulled again and it fixed it. I saw Johan made a commit about blocked devices maybe that was it. So it works really well! Connections are instant and the mouse reconnects every time. The only time that connection is slow is the first time after a reboot, like you mention above; that's not really a problem.
