yup, I was studying how to use LE in bluez recently. I can run Attribute server/
client on two Ubuntu machines. Then, I use gatttool to verify the primary and
characteristics data. I wrote my notes in my blog. If you have interests, you
could read for reference.

I only modified EnableLE and AttributeServer two values in main.conf and
add --enable-attribute on building bluez. Then, it can work. I can use dbus-send
to query data. I also wrote the notes about setting up gatttool in bluez over
BR/EDR.
