<div>Hello everyone,</div>

<div>This is a resend, I am not sure the message ever made it to the list. If it did, please disregard it. The error I received from the Postfix server at the previous send attempt is at the bottom of this email.</div>

<div>----------------------------------------------------------------------</div>
<div>I have spent the past 2 days trying to get a JABRA 250 Bluetooth headset to work with my Nokia 770. I followed the instructions at <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://maemo.org/maemowiki/BluetoothHeadset" target="_blank">
http://maemo.org/maemowiki/BluetoothHeadset </a> and everything went fine, up to the point described in the Wiki. I have also compiled the alsa-utils package to get the "aplay" utility and tried to play some sound.
</div>
<div> </div>
<div>Nokia770-45:~# ./aplay -D plughw:Headset /media/mmc1/xp.wav <br>Playing WAVE '/media/mmc1/xp.wav' : Signed 16 bit Little Endian, Rate 22050 Hz, Stereo</div>
<div> </div>
<div>This command never returns unless I press ctrl-c and kill it. There seems to be some sort of connection established, but all I hear in the headset is some hissing and popping, I have no idea how to describe it. It's definitely not silence, but it has no connection to the content of the WAV being played either. Here's what btsco says during all this:
</div>

<div> </div>
<div>The last 2 lines appear after I press CTRL-C to kill "aplay" and then CTRL-C to kill btsco.</div>
<div> </div>
<div>The same hissing/popping sounds are heard when using the "hstest" tool from bluez-utils (this one plays the sound directly over Bluetooth as far as I can tell). And also the same type of sound is heard when using chan_bluetooth (
<a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.crazygreek.co.uk/content/chan_bluetooth" target="_blank">http://www.crazygreek.co.uk/content/chan_bluetooth</a>) with the ported version of Asterisk on the Nokia 770.
</div>
<div> </div>
<div>This seems to have been reported before (not for the 770): <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://sourceforge.net/tracker/index.php?func=detail&aid=1273754&group_id=116589&atid=678258" target="_blank">
http://sourceforge.net/tracker/index.php?func=detail&aid=1273754&group_id=116589&atid=678258 </a> . However, the solution "pskey mapsco 0" only seems to work with CSR Bluetooth chips, and the 770 has a TI chip.
</div>
<div> </div>
<div>If anyone's interested, I'm attaching the output of a hcidump during all this.</div>
<div> </div>
<div>Has anyone been successful in establishing SCO connections between a Nokia 770 and a Bluetooth headset? According to this: <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://article.gmane.org/gmane.linux.bluez.devel/6728" target="_blank">
http://article.gmane.org/gmane.linux.bluez.devel/6728 </a> , Nokia is working on Bluetooth headset support. Could anyone at Nokia give us an update?</div>
<div> </div>
<div>Thank you,</div>
