I wasn't able to connect with rfcomm, but I was with hidd --connect
<bdaddr>. I've attached some sample output.

a5.txt, s5.txt, and d5.txt are what's output when I press those keys
five times.
mouse.txt is what's output when I press the mouse key and move my finger
in a Z shape from the upper left to the right, then down to the lower
left, then over to the right.
