[Bluez-devel] btsco doesn't start

[Bluez-devel] btsco doesn't start

[Nicolas Montavont]

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 :

hci0:   Type: UART

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

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

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

Re: [Bluez-devel] btsco doesn't start

[Nicolas Montavont]

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
