Kept getting a message in the Bluetooth _client_, which said the
socket timed out or received an invalid response or something. Most
people seem to believe that it is due to a bug in the Bluetooth stack
on Android 4.2.1 and suggest using reflection to access a method that
actually works as intented. I couldn't get it to work correctly though.
Kept the code here because this whole branch is a WIP, and we need
to figure out how to make Bluetooth work one way or another.
