I'm not sure of anything, but it has worked for me in the past, and I get
the exact same results if I comment out the auth and encrypt commands in
the hcid.conf file. I've left them commented out for the rest of my
debugging.

I don't think the answer is quite this simple for the following reasons:

1) my hcid.conf file has
 security auto;
which if I understand it correctly is supposed to use the
/etc/bluetooth/pin file as opposed to the pin_helper application.

1a) If I change this to "security user" the bluez-pin helper launches (but
my Palm T times out before I can enter the PIN on the laptop!) If I try to
pair the T610 phone with the laptop when "security user" is set, the
bluez-pin helper program DOES NOT LAUNCH, and hcidump -X says the
following:

HCIDump - HCI packet analyzer ver 1.12
device: hci0 snap_len: 1028 filter: 0xffffffff
> HCI Event: Connect Request (0x04) plen 10
  B2 E6 1D D9 0A 00 04 02 52 01
< HCI Command: Accept Connection Request (0x01|0x0009) plen 7
  B2 E6 1D D9 0A 00 00
> HCI Event: Command Status (0x0f) plen 4
  00 01 09 04
> HCI Event: Connect Complete (0x03) plen 11
  1A 29 00 B2 E6 1D D9 0A 00 01 00


2) My Palm T pairs correctly with the Pin in the /etc/bluetooth/pin file
when I use "security auto" (but the T610 phone does not).

3) I have pin_helper set to /usr/bin/bluez-pin (which when I run it
manually appears to work just fine...) and when I (successfully) pair my
Palm T, it does not ask me for a pin, but uses the one in the pin file (if
"security auto" is set).


I find it interesting to note that when "security user" is set, although
the bluez-pin program runs, my Palm T fails in the pairing attempt before
I have time to enter a Pin.  BUT, under the same conditions, the bluez-pin
tool never launches when my T610 attempts to pair.  {This seems to be a
problem with the hcid <-->bluez-pin tool connection?}

When I'm using "security auto" the PalmT pairs just fine with the pin in
the /etc/bluetooth/pin, but the T610 does not.

All of the above tests were done with auth and encrypt turned off.



>Even an application with L2CAP_LM_MASTER set can force the role switch
>at connection creation.

The only applications I'm running are hcid, sdpd and rfcomm which are
started in my bluetooth services (rc.d) file. I even commented out the
"rfcomm bind all" command from my /etc/rc.d/init.d/bluetooth file, but it
didn't change anything.

The default hcid.conf is quite good and you should only change the name
or class of device.

You will only accept this connection if you become the master of the
piconet.

This mean unsupported remote feature which may lead to that the phone
does not support the role switch. Check with "hcitool info ..." and
report.

And how is the sdpd started? Do you use the -m switch?

So it looks like because the phone isn't paired with BlueZ, it won't
give the information hictool is requesting...

As to the "role switch". I'm not doing anything explicitly. hcid.conf has the
following entry which may be involved:
  # Default link mode
        #   none   - no specific policy
        #   accept - always accept incoming connections
        #   master - become master on incoming connections,
        #            deny role switch on outgoing connections
        #
        #lm accept,master;
        #
        lm accept;

       # Default link policy
        #   none    - no specific policy
        #   rswitch - allow role switch
        #   hold    - allow hold mode
        #   sniff   - allow sniff mode
        #   park    - allow park mode
        #
        #lp hold,sniff;
        #
        lp rswitch,hold,sniff,park;


(If I use lm accept,master instead of the lm accept that is in the file,
the phone still does not pair...I have also tried using lp hold,snif
instead of the lp rswitch,hold,sniff,park same result, phone does not
pair.)

you set yourself into security mode 3 by using auth and encrypt. Are you
sure that you know what you are doing?

The PIN helper can't provide a PIN as it seems. Fix this.

Even an application with L2CAP_LM_MASTER set can force the role switch
at connection creation.

When attempting to pair blueZ with the T610 Phone:
hcidump -x gives:

obviously, I see where they start to diverge, but I don't know
why...

As I said, I can pair a palm T to the computer, so my PIN appears to be
working correctly... and I can pair the phone with the Palm T, so the
phone appears to be at least paritally working...

this is unsupported remote feature. What says "hciconfig -a" and
"hcitool info <phone-bdaddr>"? Are you forcing the role switch?

[Bluez-users] Trouble pairing with new phone...

[Jay W. Summet]

Ok, I had a SE T610 phone, and it paired with BlueZ no problems. I also
have a Palm T and it paired with no problems...

The phone stoped charging, and I got it replaced under warantee.

Now, I can't pair the phone with the laptop running Linux/Bluez. (After
entering the PIN on the phone, it gives a "Bluetooth connection failed"
message.)

I deleted the pairing between all devices.

The phone is able to pair with the Palm. The Palm is able to pair with the
laptop (running Bluez) and the phone. The phone still won't pair with the
laptop.

My questions:
1) Is there a way to initate pairing FROM the laptop?

2) Anybody see this type of behavior before?
 (Is it a problem with my new phone? The old one worked fine...)

Jay

[Bluez-users] Re: Trouble pairing with new phone...

[Jay W. Summet]

As an update, I just had a friend of mine try pairing with HIS SE T610,
and it didn't work any better.  So I'm wondering if this behavior is
common to all SE T610's?

I'm using HCID/SDPD version 2.10 (Mandrake 10.1).
