 I am in need of a solution to help me use the obex-server programmatically.

        What I need to do is whenever a file is recieved at the server I 
get some kind of callback or signal, so I can call some other 
program/function which was waiting for files from bluetooth. I need this 
to be done in a for loop until the remote device disconnects. It would be 
great If I can call the file recieving code as a waiting function call in 
my code. 

	Any help or pointers are appreciated.

  To: bluez-devel; +Cc: can't, get, a2dp, to, work

hello

I have a problem getting my a2dp connection onto my headset to work on my linux
machine.
But the sco connection works (I didn't test the mic sofar).

I searched the internet for a hint how to solve this matter, but didn't find
anything.
So I think this is the appropriate spot to post my problem.

  Sorry if I'm wrong.

I'm running Debian Sarge with a newly compiled kernel 2.6.14.3.
I got the whole bluetooth subsystem (except debugging I think) coded into the
kernel,
along with the ALSA system.
Following packages are installed:

bluez-utils    2.15-1.1
alsa-base      1.0.8-7
alsa-utils     1.0.8-4

The bluetooth-alsa version is the 0.4 from the cvs. It compiled without any
error,
along with the kernel snd-bt-sco module.

To test the sco connection I did the following:

-load snd-bt-sco
-pair headset with computer ('hcitool cc <btaddr>' with auth and encrypt enabled
in
 hcid.conf, as I think a2dp requires both)
-'btsco <btaddr>'
-play audio using xmms with appropriate alsa-device

After aborting btsco, but leaving the headset still paired I tryed to play audio
via
the command provided on the official bluetooth-alsa site:

 >debian:/usr/src/btsco-0.4# hcitool con
 >Connections:
 >        < ACL 00:13:1B:00:50:32 handle 46 state 1 lm SLAVE AUTH ENCRYPT
 >debian:/usr/src/btsco-0.4# mpg123 --au - smooth.mp3 | ./a2play
00:13:1B:00:50:32
 >High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2 and 3.
 >Version 0.59r (1999/Jun/15). Written and copyrights by Michael Hipp.
 ...(I Cut out part of the mpg123 output)
 >Playing MPEG stream from smooth.mp3 ...
 >Junk at the beginning 49443303
 >MPEG 1.0 layer III, 192 kbit/s, 44100 Hz joint-stereo
 >out of sync (0x2e)
 >couldn't read header on -

At next I tryed the seccond command provided on the site:

 >debian:/usr/src/btsco-0.4# mpg123 --au - smooth.mp3 | sbc/sbcenc |
./sbc/rcplay 00:13:1B:00:50:32
 >High Performance MPEG 1.0/2.0/2.5 Audio Player for Layer 1, 2 and 3.
 ...
 >Playing MPEG stream from smooth.mp3 ...
 >Junk at the beginning 49443303
 >MPEG 1.0 layer III, 192 kbit/s, 44100 Hz joint-stereo
 >Can't get channel number: Success

I'm focussing on the "out of sync" error message now.
The usage of a2play tells me that I'm able to define the input file directly.
So I did:

 >mpg123 --au - smooth.mp3 > smooth.au
Now I got the song in sun audio format.

I tried the following next:

 >debian:/usr/src/btsco-0.4# ./a2play 00:13:1B:00:50:32 smooth.au
 >out of sync (0x2e)
 >couldn't read header on smooth.au

Next up was a different audio format, and hey, the errorcode changed:

 >debian:/usr/src/btsco-0.4# ./a2play 00:13:1B:00:50:32 smooth.mp3
 >out of sync (0x49)
 >couldn't read header on smooth.mp3

So there must be something wrong with the audioformat, I guess.
I seriously don't know which one works or should work.

The headset istself is called "Cyber Headphone".
At least it shows up that way when i do 'hcitool scan'
The headset itself works fine with the a2dp connection running winXP and a
Toshiba stack.

Thanks for the help.

Hi, 

Could you guys add BPP ReferencePrinting service into the sdptools and
checked in? I don't know how many perple will benefit from this, at
least it will not hurt. And I think more people will use it later. 

and if you checked in, could you let me know the CVS version number? 

Thanks. 

Lan

Hi all,
I made a simple software to send small pictures to all bluetooth  
devices in range (it's used by a museum ).
This software is made in C using bluez api, I've used two bluetooth  
dongles : one to make periodic inquiry (not with HCI periodic inquiry  
command by with a loop) and the other to make sdp query looking for  
obex push service and sending image.
My requirement was to use this software in some embedded linux based  
computer so I chose to limit external library, I made all using  
pthread so there is an infinite thread for inquiries and one thread  
to handle every sdp query and relative connection when devices are  
discovered. I've discarded also using python or other scripting  
languages for the platfom limitations.

All works but I found it not so efficient, also with 6/7 devices it's  
really slow to identify and connect to devices, some times connection  
are unexpectedly closed and so on....

Is it my approch to the problem wrong or bluetooth protocol is not  
suitable for this type of use?

I'm using libs version 3.7-1 (on debian 4.0)

Many thanks
Fabrizio
