Hi!

It sound like a pin problem. Try first to connect to you headset with:
# hcitool con 3B:59:A0:94:0A:00

If it is also refused, try to change the security settings in 
/etc/bluetooth/hcid.conf to user or to none and try to reconnect with 
the above command.

No, it's not refused, but I see no connections.

When I have changed the hcid.conf, what to do to use the changes?



my original hcid.conf:

device {
	# auth disable;
	# encrypt disable;
	iscan enable;
	pscan enable;
	name "BlueZ %h (%d)";
	class 0x700100;
	lm accept;
	lp rswitch,hold,sniff,park;
}
options {
	security auto;
	autoinit yes;
	pairing multi;
}

try to replace the line :
    security auto;

by:
    security user;
or:
    security none;

here is an extract of the hcid,conf that was installed with ubuntu:

         # Security Manager mode
         #   none - Security manager disabled
         #   auto - Use local PIN for incoming connections
         #   user - Always ask user for a PIN
         #

Hi all.

I'm not sure but I see in the "connection-display" that my headphone is
master. Is this right or should it be slave?


an for hciconfig -a I read that the dongle is slave?

How do I change this? (I need to?)


# hciconfig -a
hci0:   Type: USB
        BD Address: 00:0A:94:02:7D:A0 ACL MTU: 384:8 SCO MTU: 64:8

        Manufacturer: Cambridge Silicon Radio (10)



I also can't connect a rfcomm socket

# rfcomm -i hci0 connect 0 00:0A:94:A0:59:3B 1
Can't connect RFCOMM socket: Resource temporarily unavailable


What ca I do, step by step, do get more informations to let the
headphone work? I think there is something wrong with my configuration
but I don't know what.


Thanks 


Johannes

It doesn't matter; the profiles above don't care.  There's actually a
power advantage to being master.  The difficulty comes if you need to
connect another device to the other end; then you end up in a scatternet
if that end is not the master, and that causes a considerable loss of
efficiency (and possibly worse).

fwiw, the itech r35 wouldn't allow a connection from my pc until i
changed hcid's link mode from

lm accept,master;

to

lm accept;

and restarted hcid. It may be because at the time the headset was also
connected to my cellphone... later on it didn't have this requirement.

headsets that can do a2dp and headset/handsfree may prefer or require
being master so they don't have to do a scatternet to communicate to two
devices at the same time.

in all cases the same result: it does not work!

This in my configuration file:

device {
	# auth disable;
	# encrypt disable;
	iscan enable;
	pscan enable;
	name "BlueZ %h (%d)";
	class 0x700100;
	lm accept;
	lp rswitch,hold,sniff,park;
}
options {
	# security auto;
	# security none;
	security user;
	autoinit yes;
	pairing multi;
}


Next I tried when the headphone is in pairing-mode:
# hcitool inq
Inquiring ...
        00:0A:94:A0:59:3B       clock offset: 0x3453    class: 0x240404

And the same in headphone-normal-mode:
# hcitool inq
Inquiring ...

Is this correct?


When trying to play a mp3 I get this result:
