[Bluez-devel] bluetooth headset not working

[Bluez-devel] bluetooth headset not working

[Kevin Fenzi]

[-- Attachment #1.1: Type: text/plain, Size: 1086 bytes --]

Greetings. 

I recently had a chance to look at the new bluez-utils and the setup
for headsets. Very much nicer than any of the old methods. :) 

However, I can't seem to get my headset working with twinkle (or any
other phone app). 

I have setup my ~/.asoundrc. 
I can play audio to my headset via mplayer or aplay fine. 
When I try and set twinkle to use the ALSA bluetooth device it seems
like it opens the headset, and then it spits out: 

ALSA lib pcm_bluetooth.c:417:(bluetooth_hsp_hw_params) Protocol not
available (92) 
ALSA lib pcm_bluetooth.c:417:(bluetooth_hsp_hw_params) Protocol not
available (92)

Then it goes to 100% cpu and unresponsive. 

ALSA bug? or bluez-utils? Anyone seen this before or have
a work around? 

twinkle-1.1-3.fc8.x86_64
alsa-lib-1.0.15-0.2.rc2.fc8.x86_64
bluez-utils-3.20-2.fc8.x86_64

I talked with the twinkle developers, and they say it's not an issue
with twinkle. See: 
http://tech.groups.yahoo.com/group/twinklephone/message/1879?l=1

Happy to provide info or debugging... CC me for faster response.

aplay or mplayer are talking to the ALSA device that uses the A2DP profile.  
The phone app needs to use the device with the HFP profile.  It looks like 
you got that set up in .asoundrc since a plausible subroutine is reporting 
the error.  Next question: does your headset do HFP, or is it purely a 
music headset (A2DP)?  Some headsets, including the Motorola HT820, will 
auto-switch, but I think not every music headset will do so.  Hope this 
helps!

Humm... do all headsets do A2DP? I thought mine did not.

I am using a jabra BT 250v headset. 
It's not a music headset. 

I have a few more headsets I can dig up here to test with if you think
it's something with the jabra.

The ones with 2 earpieces and a mass of about 100 grams invariably (?) do 
A2DP which transmits stereo at 44100 Hz or 48000 Hz, compressed with the 
SBC codec.  The single-ear ones with a mass of about 20 grams invariably 
(?) do HSP/HFP, monaural at 8000 Hz, I think uncompressed.  That would be 
your Jabra BT 250v.  Some but not all of the music headsets can switch 
protocols and have call control buttons for HFP; these are advertised as 
"works with Skype".

So the Jabra is capable of doing the HSP protocol, and when the message 
says the protocol is "not available", the problem is likely not in the 
headset.  Not likely that the headset is broken or has buggy firmware, but 
just for paranoia, it would be a good data point if the same message were 
seen with a different headset.  

I've seen a similar message when I didn't have bluetoothd-service-audio 
configured to autostart and forgot to start it manually.  Do you have the 
corresponding protocol/profile daemon running?  I don't have my laptop 
handy to look up the name of this daemon but I think it's 
bluetoothd-service-sco.  This is in bluez-utils-3.19 (3.20 is latest; 
probably came in at 3.16.)

Unfortunately that's about the limit of my expertise, since I haven't 
messed with the HSP/HFP feature of the Motorola HT-820 that I have.

Actually bluetoothd-service-audio takes care of both A2DP and HSP.  
Unless you specified explicitly the profile to use in your .asoundrc  
(e.g. "profile a2dp") the selection process goes as such that A2DP is  
used if available and otherwise HSP.

Right. Thats my understanding as well.

I can duplicate it with another headset here later...

bluetoothd-service-audio?

Yeah, seems to run fine, but makes no difference in the output. ;(

Bummer. Thanks for helping out!

If anyone else has any ideas I would love to get this working...

      Do u mean the bluetoothd-service-audio will read .asoundrc?
      could you tell me how to write .asoundrc if i want to use a2dp and
hsp.now my .asoundrc is:

      pcm.headset {
      type bluetooth
      }

      ctl.headset {
      type bluetooth
      }

      pcm.bluetooth {
      type bluetooth
      device 00:0D:3C:EB:53:F0
      }

when i use  "aplay -D bluetooth -f S16_LE /1.wav ",i will get the following
error.

No. The values in .asoundrc are given to the bluetooth alsa plugin  
which then passes them over to the audio service using a unix socket.

If you want to have one alsa device for A2DP and another for HSP it  
might be a good idea to explicitly state the profile you want to use  
for each device. You do this by providing a line such as "profile  
a2dp" in addition to the device and type lines. I just checked the  
code and the plugin will map "hifi" and "a2dp" to A2DP and "voice"  
and "hfp" to HSP (it's actually a bug that it doesn't recognize "hsp").

Looks like the audio service crashed. What architecture are you  
running this on and what compiler did you use? It would be good if  
you could try to reproduce this by running bluetoothd-audio-service  
through valgrind or gdb and get a proper backtrace of the crash. To  
do this remove the /etc/bluetooth/audio.service file (hcid should  
detect this and unregister the service but if it doesn't you need to  
restart hcid), and run "/usr/lib/bluetooth/bluetoothd-service-audio - 
s" either through gdb or valgrind.

Looks like the audio service crashed. What architecture are you  
running this on and what compiler did you use? It would be good if  
you could try to reproduce this by running bluetoothd-audio-service  
through valgrind or gdb and get a proper backtrace of the crash. To  
do this remove the /etc/bluetooth/audio.service file (hcid should  
detect this and unregister the service but if it doesn't you need to  
restart hcid), and run "/usr/lib/bluetooth/bluetoothd-service-audio - 
s" either through gdb or valgrind.

hi Johan
    the crash of bluetoothd-service-audio has been resolved now.i think it 
is a bug.in avdtp_stream_get_transport(),the mtu pointer will be 
unaccessible.
In a2dp_setup_complete(),avdtp_stream_get_transport() wants to pass the 
address of cfg->pkt_len.but the cfg is a packed struct.so the normal 
pointer of uint16(pointer mtu in avdtp_stream_get_transport is this type) 
should not be used here.of cause my cpu is arm.

 
thanks

No. The values in .asoundrc are given to the bluetooth alsa plugin 
which then passes them over to the audio service using a unix socket.

If you want to have one alsa device for A2DP and another for HSP it 
might be a good idea to explicitly state the profile you want to use 
for each device. You do this by providing a line such as "profile 
a2dp" in addition to the device and type lines. I just checked the 
code and the plugin will map "hifi" and "a2dp" to A2DP and "voice" 
and "hfp" to HSP (it's actually a bug that it doesn't recognize "hsp").

Thanks for this info. It should now be fixed in the CVS.
