Hi Juan,
I copied this to the discussion list as others may be interested.
The BTRespond sample works with iCommand or other Bluetooth client programs,
such as the Lego Mobile Phone application.
Run the BTRespond example and it waits for a connection. You can then connect
to the NXT using iCommand. An example such as DirectNXT works. You should use
1234 an the PIN. "Connected" is displayed on the LCD when a successful
connection is made.
You can then control the NXT using the Lego Communications protocol. The
emulation of the Lego Communications protocol is not perfect but it allows
several different Bluetooth remote control programs to drive the NXT.
You can extend BTRespond and process MESSAGEWRITE commands sent from a PC or
other client. Currently BTRespond closes the connnection, and waits for a new
connection if you send it any MESSAGEWRITE command, but you can make messages
do whatever you like. (Brian added a Message class to iCommand to make it
easier to send MESSAGEWRITE commands , but I am not sure that it is in an
iCommand release yet).
I have not tested initiating a connection from the NXT mainly because I do not
have a second NXT. There is no high-level support for this in the Bluetooth
class, but it may work by sending the appropriate low-level commands to the
Bluecore chip, in the same way that the LCP class does. This can be done from
Java, but you will need to read the Bluetooth Interface Specification in the
Lego Blueooth Development Kit, to understand how to do this.
In a future release, we will add Bluetooth Java stream processing and
high-level methods for connecting to another NXT.
The next release will also support downloading programs over Bluetooth.

Hi, Lawrie, I tested 0.2 version with the examples and I dont have any
problem.
Good Work.
But I dont know how to use Bluetooth Communication. I dont understand the
example BTRespond.
Currently I am testing Ultrasonic Sensor and Hitechnic Compass Sensor, and I
dont have any problem.
I have developed a Simple Class R2D2 to test Sound Class:
