The Bluetooth submenu will let you make a wireless
connection between your NXT and other Bluetooth devices
(like other NXTs, and computers). You can use a wireless
Bluetooth connection to send programs to other NXTs, to
download programs from your own computer
without using a USB cable, or other cool things like using the
Remote Control in the software to get direct control of your
robot and send it on missions!
