I was assuming that some of the profiles are already implemented and can easily be re-used for your application. If I were to write my own profiles is there any book/reference that can guide me? I'm planning to write applications to build PAN, exchange objects and IM chat...

Hcidump -x gives me something like..
device: hci0 snap_len: 1028 filter: 0xffffffff

and the process does not exit, unless I suspend it explicitly.

stop thinking in profiles. Profiles are applications and since we are in
the Linux world, yes, there are already some applications do deal with
certain profile definitions from the specification.

For PAN you can use pand and for object exchange there are lot of them,
but none of it is the default one. The IM chat would be tricky, because
there is no standard for it. However as Michal already posted, there is
a project for it.

Of course. It will show you the HCI packets when you establish a
connection from another terminal. If the device is idle you will see
nothing and if you run it a non-root you will see only a few packets.

[Bluez-users] BT programming

[Mandalia Hiren-AHM047]

hi there

I'm a newbie to BT programming. I have successfully installed my BT 
hardware device using BlueZ packages. As a next goal I need to write my own code for simple applications like Chat and/or PIM Item Transfer based profile. Does blueZ have implemented profiles like OBEX, DUN, etc that I can use?
 
Also when I'm trying to connect to a particular remote BT device using  
hcitool cc .. it does not work..no connection is established.. any idea why is that happening?
 
Thanks
Hiren Mandalia

the profiles are implemented in applications. Either you find a
application that fits your needs or you have to write one. Be more
specific about what profiles and what roles do you wanna support.

Check with "hcidump -X" what's the error code, but as I always say there
is no need to establish an ACL link by hand. The kernel core will do it
when one is needed.

Marcel
