Description Håkon (reporter) 2009-12-15 16:58:09 UTC
SOFTWARE VERSION: Maemo 5 1.2009.42-11 (N900)

EXACT STEPS LEADING TO PROBLEM: 
1. Connect handsfree (jabra BT2050) to N900 using the GUI 
2. Make a normal call or inncomming call using GSM/3G nettwork


EXPECTED OUTCOME: Having a normal conversation using handsfree

ACTUAL OUTCOME: loosing sound in the handsfree, having to revert to handset.
After you try to disconnect the handsfree you get a black screen (camerabutton
brings you back...)

REPRODUCIBILITY:
(always, less than 1/10, 5/10, 9/10)
1/3

EXTRA SOFTWARE INSTALLED:happens from day one of use

OTHER COMMENTS:other strange things happens, allso like random disconnects, but
nothing concrete.
This BT handsfree workes on Nokia 5800XP

Comment 1 Andre Klapper maemo.org 2009-12-16 23:56:44 UTC
Thanks for reporting this.

This sounds very similar to bug 5959 which is about different hardware though.


So, how to get more info here (I hope I am not wrong with this):

There are two different logs that would be useful. The first is bluetoothd
debug logs and the second is a HCI-level trace.

For the first you'd need to:

1. install the klogd and sysklogd debian packages (and probably reboot the
device afterwards)
2. after booting and before doing anything with bluetooth do "killall -USR2
bluetoothd" (as root) to enable bluetoothd debug logs
3. after reproducing the issue "grep bluetoothd /var/log/syslog >
bluetoothd-log.txt" and attach the file here.

For a HCI trace do:

1. install the bluez-hcidump debian package
2. (as root) run "hcidump -B -w hci-trace.log while reproducing the issue
3. attach the hci-trace.log (or whatever filename you chose) here

See http://wiki.maemo.org/Documentation/devtools/maemo5 for more information on
how to install the requested packages.

I can confirm on this too. I have the same problem. Everything connected and
the feed back to the headset is received. But when you try to make a phone
call. The sound just choppy and distorted that you cannot understand. I really
hope this bug is fixed..

Maxx: See comment 1.
Comment 4 Maxx 2009-12-29 00:44:18 UTC
 Andre Klapper: provide me the link to Bluez-hcidump for debian and does it
have any compatibility issue with Maemo 5?

Same bug happens also with Nokia BH-904 headset.
Comment 7 Andre Klapper maemo.org 2010-01-14 17:03:12 UTC
Today Nokia released the Maemo5 update version 2.2009.51-1 for public (also
called "PR1.1" sometimes).
If you have some time we kindly ask you to test again if the problem reported
here still happens in this new version - just leave a comment and please also
tell your exact model (though this report originally is only about Jabra).
Comment 8 Maxx 2010-01-14 22:48:44 UTC
Hello Andre,
with the latest update version 2.2009.51. the problem still persist. Sound is
lostly bad. The only way to make ot clear is to try connect to wifi while
making a phone call. 

It happened all the time from day 1 to now. Nothing is fixed. bluetooth headset
works with N95 and N93i just fine. Please fix this terible bug. This device is
almost unusable with handfree kits connected with bluetooth.
Comment 9 Andre Klapper maemo.org 2010-01-15 17:47:12 UTC
Håkon uses Jabra BT2050.
Marko uses Nokia BH-904.
Maxx... no idea.

So:
1) Does this still happen with 2.2009.51-1 (that version has quite some 
   Bluetooth fixes)?
2) If yes, please provide the exact hardware that you use, plus please provide
   a log as explained in comment 5.

Otherwise there's nothing that can be done here.

Comment 12 Håkon (reporter) 2010-01-29 18:00:20 UTC
Yea 3. call in the middle of a sentence i lost the sound again from the BT
handsfree.
Is there any easyer way to get a debug to you ?
Comment 13 Maxx 2010-01-29 22:10:40 UTC
I got Advantalk vfu-bths-03 headset. 
This headset worked flawlessly on my Nokia N93i and N95. But i can't use it on
N900 as explained above. 

so please fix this problem. Bluetooth stack in this device has some serious
stacking issues.
Comment 14 Håkon (reporter) 2010-02-19 16:16:21 UTC
Latest patched fixed this for Jabra BT handsfree.
Comment 15 Andre Klapper maemo.org 2010-02-19 16:20:18 UTC
Great that it works for you now, and thanks for updating here.
