Emmanuel,
I don't think the standard Lego software works with BTRespond, although there
is no real reason why it shouldn't as BTrespond, and the LCP class that it
uses, emulate most of the commands that the standard Lego firmware supports.
However, I did not get the LEGO software to work with BTRespond, but I did not
try to debug why it wasn't working as I did not think anyone would want to use
the LEGO software with lejos. The Bluetooth programs that I have successfully
got to work with BTRespond are: iCommand, the Lego Mindstorms mobile phone
program, my own mobile phone program, and a PC remote control for the NXT
called OnBrick.
The NXT screen remains blank when BTRespond is running until a connection is
successfully displayed, when it says "Connected".

Hello,
I would like to run the simple example BTRespond. Do I really need to
download iCommand to run it ? So far I managed to connect my computer with the
NXT thanks to a Bluetooth stick I plugged via USB in the computer. The computer
says it is connected but the NXT's screen stays blank. I guess I can't use the
LEGO software as it assumes that the NXT runs with the LEGO firmware.
Regards,
Emmanuel

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.
