Hello,

for a Java programm I have to know the bluetooth device class of my lokal
bluetooth device

local.init('myName', 0x010101);

But I have no idea what device class and so which number I have to enter.
Can you help me? I use a laptop with USB bluetooth dongle and win xp sp2.
I already had a look to the bluetooth specification (Assigned Numbers) but
did not understand it.

best regards
Sarah

This depends on what kind of device and what services you are offering to
prospective users.

Let me know this and we can choose the right one!

Hello Rob,

Well, my intension is to write a software for a local computer which
monitors if a particular Bluetooth device (usually a mobile phone) is
available.
So, my Computer (a laptop by Asus) is equipped with a Bluetooth USB Dongle
(class 2). The Operating System is Windows XP SP2 but I think this should
not be important, is it?. The device I currently want to detect is a Nokia
6230 but this should not be important as well, right?
I don't mind which services the mobile phone os offering. I just want to
discover the device.s

The important line in the library i'd like to use is

local.init('myName', 0x010101);

This is the line where my local Bluetooth device (the USB Dongle) is going
to be initialised. But this line of code doesn't work. I have to enter the
"right" class number for my device instead of 0x010101.

If you need more information, please tell me!

Best regards
Sarah

Doesn't work how? it won't compile, won't run..... What java API are you using?

To define a CoD for a laptop computer from the assigned numbers document we can
use.....

Major Service Classes (bits 23-13)
Nothing relevant so: 00000000000

Major Device Class (bits 12-8)
Computer : 00001

Minor Device Class (bits 7-2)
Laptop: 000011

Format (bits 1-0)
standard format: 00

So from MSB->LSB we have

00000000000 00001 000011 00

hence

00000000 00000001 00001100

in hex is: 0x00010C

Hope this helps

Rob
