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:

Please I need help with Bluetooth Feature.
Thanks.
Un abrazo.
