Pebble autodetection for OS X
Pebble autodetection for OS X

On POSIX systems (specifically OSX) this will attempt to auto-detect
the Pebble device node. If multiple nodes are present it will try to
use the most recently used Pebble.

I'm not sure what the Linux naming convention is for bluetooth devices
- the autodetection routine is simple to modify once I have examples.

Windows will require some work with device enumeration since COM ports
are not named.
