[Bluez-users] Profiles on Bluez

[Choi Sonim]

Hello ppl!

What Bluetooth profile do BlueZ support ?
I found some OBEX utilities (which both gnome and kde provides),
and the builtin BNEP support. but that;s it. no hands-free, bpp, opp,a2dp,ftp,
nothing ?

I know it is high-level and everything can be written on top of bluez
but i wonder what is already supported ?

Thank You ppl,
Choi.

SCO (handsfree), A2DP and AVRCP are supported by the bluetooth-alsa driver
http://bluetooth-alsa.sourceforge.net

BPP, depending on which way you want to use it, is a bit of an issue at the 
moment.  I haven't yet found a server that lets my PC accept print requests 
from mobile devices and print them through CUPS.  However working the other 
way, CUPS has a bluetooth backend that supports adding queues for bluetooth 
printers (I believe using HCRP).

OPP and FTP are handled just fine by KDE's 'kdebluetooth' package, if you have 
it installed, bluetooth:/ in a konqueror view should give you a device 
listing, double clicking a device icon should display supported profiles, FTP 
is called "OBEX File Transfer".  In OPP's case, sending a file from a device 
to the PC should automatically open a dialogue to facilitate recieving it.  
Sending files is as easy as right clicking them in a konqueror view and 
selecting "Actions> Send with Bluetooth...".  Gnome's bluetooth utilities 
should have similar funtionality, I cannot comment further as I've never used 
them.

Hi Thomas,

Thank you for the help.

I also found that BlueZ supports PAN and BNEP inherently.

can I please ask about more profiles and protocols like goep, obex, spp, hid,
dun, spp ?

Are they supported ? by whom,where ?

Thanks again !!!!
Choi.

I have to confess, at this point, some of my knowledge on this subject comes 
from Wikipedia; http://en.wikipedia.org/wiki/Bluetooth_profile

You'll need to clarify OBEX, as there are a number of services built on it
GOEP, "Generic Object Exchange Profile" is one of them, I know nothing more 
about it than wikipedia can tell you (not much).  It doesn't appear to be a 
user-accessable feature so much as a basis for other profiles.
OPP I mentioned in my last email, is the one-way sender-initiated file 
transfer protocol.
FTP is similar(ish) to OPP, but usually reciever initiated, and supports file 
browsing, deleting, etc on the remote host.  As mentioned last time, KDE's 
bluetooth services offer it, I forgot to mention obexftp however: 
http://triq.net/obex

There are likely daemons to facilitate OPP recieves other than KDE or GNOME's 
bluetooth packages, but the names of any of these are escaping me.


The HID protocol, compared to most, is simple.  bluez-utils 
provides /usr/bin/hidd, which in general is all you need to use it.  Its man 
page, HIDD(1) contains very little information (as of bluez-3.7), but the 
commands are intuitive enough:
'--server' starts a server for inbound HID connections (for example, my 
cellphone (Sony Ericsson K750i) has a feature it calls "remote control" that 
works with hidd in this way)
'--connect 00:00:00:00:00:00' connects to an active bluetooth input device.  
most keyboards/mice work like this.
'--search' looks for active devices and tries to connect to them 
automatically.


Someone else will have to fill in the details about DUN, bluez provides a 
binary called 'dund', but I don't have a clue how it works.


SPP is handled by rfcomm, which is also simple.
# rfcomm bind rfcomm0 00:00:00:00:00:00 [bluetooth channel]
will create /dev/rfcomm0 as a serial port to the chosen device, which can be 
used by any app (you might need to check permissions, naturally).


# rfcomm release rfcomm0
will delete the device again.


I think that covers just about everything you asked for, feel free to ask for 
clarification on anything.

It is used for dial-up networking (LAP (LAN Access over PPP)), either
with --listen as a server, or with --connect as a client. See e.g.
http://synce.sourceforge.net/synce/bluetooth.php
