Talk:Bluetooth headset
From Gentoo Linux Wiki
I can comfirm that the Sony Ericsson HDH-DS970 headset also works flavlessly.
A note on ALSA and a2player with Mplayer,Xine,XMMS and everything that you want to stream to your headset. Since I was unable to find *anything* about how to get a2play to work with a ALSA sound socket (ie, like /dev/dsp)
Run "a2play -d <bt-address> /dev/dsp" and take an adio cable from the audio output to line-in and you have a stereo bluetooth headset with alsa.
You may also need to have this .asoundrc file in your home directory

[edit] Modifications to BTProximity for a more accurate value
I have modified the btproximity script to give a more accurate meridian value since when it lost connection and had to reconnect it always gave a few (1-3) results as 0 even tough the result should not had been that.
This is only the modified sections
| Code: |
function check_connection {
connected=0;
found=0
for s in `$HCITOOL con`; do
if [[ "$s" == "$DEVICE" ]]; then
found=1;
fi
done
if [[ $found == 1 ]]; then
count=$(($count+1));
connected=1;
else
msg 'Attempting connection...'
count=1; rssi=0; rssi_data=0; rssi_total=0; # Reset the collected data
if [ -z "`$HCITOOL cc $DEVICE 2>&1`" ]; then
msg 'Connected.'
connected=1;
else
msg "ERROR: Could not connect to device $DEVICE."
fi
fi
}
if [[ $connected -eq 1 ]]; then
rssi_data=`$HCITOOL rssi $DEVICE | sed -e 's/RSSI return value: //g'`
rssi_total=$(($rssi_total+$rssi_data));
rssi=$(($rssi_total/$count));
if [[ $count -ge 5 ]]; then # Only check rssi value if we have 5 or more results
if (( $rssi <= $THRESHOLD )); then
if [[ "$state" == "near" ]]; then
msg "*** Device \"$name\" [$DEVICE] has left proximity"
state="far"
$FAR_CMD > /dev/null 2>&1
fi
else
if [[ "$state" == "far" ]]; then
msg "*** Device \"$name\" [$DEVICE] is within proximity"
state="near"
$NEAR_CMD > /dev/null 2>&1
#$START_CMD &
fi
fi
fi
msg "$count, state = $state, RSSI = $rssi, PID = $PID"
fi
sleep $CHECK_INTERVAL
done

[edit] Sony Ericsson HBH-IV835
Bought this headset yesterday, works flawlessly with Skype. Had to upgrade btsco[-kernel] to 0.42 to get a reliable connection.
Music streaming marginal from a Bluetooth 1.2 (CSR) adapter, headset is mono anyway.
Volume controls seem inactive, but the headset is stated as having automatic volume adjustment so volume levels have not been an issue.
As stated (added to the table), the design of the headset is such that it drops the bluetooth link after a short period of inactivity. I'm not sure how easy it would be to script btsco to connect to the headset when a program requests audio i/o, but that would be the idea solution, rather than manual link initiation, or continuously reconnecting (and draining the battery). EDIT: This appears to be fixed with >=bluez-(libs|utils)-3.0, more testing appears to be necessary.
[edit] Needs an update
Several things about this howto and the ebuilds in bugzilla need to be updated, Boky please do so. Ofcourse these are my experiences, I could also be doing something wrong.
- Both the plugz-cvs and libsbc-cvs don't work with the very latest cvs (probably because of some quirk of them committing a little change upstream). The bootstrap.sh file has wrong permissions. So you need to insert a "chmod 755 bootstrap.sh" into both ebuilds before where it does "./bootstrap.sh ...".
- I'm really having a lot of difficulties with bluetooth-alsa-kernel (and with it's predecessor btsco-kernel). Maybe I'm just using a too new kernel or missing some unspecified dependency (emu10k1 in kernel crossed my mind but this isn't it). It just fails to emerge with lots of errors (actually I got it to emerge once some time ago, so I must be close) and I don't seem to need it. I just remove the dependency from the bluetooth-alsa-utils ebuild. I don't install bluetooth-alsa-kernel but apart from that I do everything the same.
- Why do both plugz-cvs and bluetooth-alsa-utils partly install the same files? Something is not right here. I need to install bluetooth-alsa-utils last (so I'm actually still using btsco-0.5) otherwise I only get silence.
Wouldn't it be time to consolidate and make non-cvs ebuilds (as the cvs ones will cause lots of headaches in the future)? And for heaven's sake someone with inside information please clean up the bugzilla page.

Shouldn't the alsa USE flag be set in package.use or via ufed? 98.204.30.89 12:52, 4 July 2008 (UTC)
