Dear Developers,
I just bought an Plantronics M2500 headset and I have problems to make
it work in my linux box. I hope you can help me.
The problem is I can not start btsco. Here is the output when I try to
start btsco :
Device is 2:0
Error: btsco open (2-0): No such device or address
Here are the details of my settings:
I have a bluetooth PCMCIA 3com card, version 3 (driver serial_cs and
hci_uart), and a linux-2.6.9 kernel (with bluetooth support from this
kernel), btsco from CVS (revision 1.4 when I load the module). Alsa
driver (1.0.8) were compiled outised the kernel.
I also try with the linux-2.6.10 kernel with patch-2.6.10-mh3.gz from
bluez, and I get the same.
Once I did hciconfig hci0 up and hciattach ttySx 3com, I can see my
headseat :
hcitool scan gives me :
00:03:89:79:84:48 M2500 by Plantronics
(to have this result, I have to put the headset in connection mode.)
but hcitool info 00:03:89:79:84:48 gives me :
Requesting information ...
Can't create connection: Connection timed out
I have same outputs if I try sdptool (sdptool browse or cc...)
In the Readme file it is written
3. run the daemon (enter the passkey if it's the first time 'round)
btsco bdaddress
How can I set the passkey ? I know I have a code (0000), when do I have
to set up this code ?
Here are other details, as you suggest in readme file :
hciconfig -a :

Any help would be really appreciated. Thanks a lot...

Hi Nathanael and Lars,
Thanks a lot for these clarifications... I succeed to establish the
connection through btsco.
I finaly use the alsa modules in the kernel and make the modification
to hcid.conf.
While it worked with aplay, it didn't work with gnomemeeting and then I
tried to disconnect and reconnect. Now, I always get the following
message, even after rebooting :
Can't connect RFCOMM channel: Permission denied
If I try sdptool --search ... it gives me the same output (Permission
denied).
I get this either if I put the headset in pairing mode or not.
I am sorry to ask these questions, I am not really familiar with this
equipment...
Thanks again !
Nicolas

Hi Nicolas,
I had similar problems getting the M2500 headset, it's not getting the
Pin # when first connecting. I created a simple file pin_helper_simple:
#----------------------
#!/bin/sh
echo "PIN:0000"
#----------------------
Then I modified the hcid.conf under options{} and pointed to the new pin
helper:
pin_helper /etc/bluetooth/pin_help_simple;
After that running btsco <address> worked. Also note, for the first
connection you might have to put the headset into pairing mode.
Cheers,
Nathanael

looks like an alsa problem, because this device means the alsa device.
It detects that your snd-bt-sco is device 2 (third sound card) but it
seems to have a problem to connect. Maybe a problem with alsa-lib? Can
you connect to the snd-bt-sco by other programs, like alsamixer? In your
case it should be alsamixer -c2
I'm no expert for this part though... (if I'm for any part at all, anyway).
best regards,
~ Lars
