[Bluez-users] rfcomm pairing and timeout

[Bluez-users] rfcomm pairing and timeout

[Andreas Fehr]

Hi

I've still a problem with pairing my phone with my bluetooth dongle. My 
phone asks me if I want a serial port connection with computer. As soon 
as I accept this, the dialog to enter the pin shows but disappears 
within about 1 second. Far to few time to enter any pin.

Is there a way to set some other timeout for pairing? Just in case it 
helps, I dumped the bluetooth connection below (including timestamps and 
some hint where I want the enter the pin). (./hcidump -X -V -t)

Thanks for any hint,
Andreas

and what hardware are you running this on? Is it Intel, AMD, 32-bit or
64-bit (uname -a).

Hi Marcel,

it's a Fujitsu Siemens Lifebook P7020 with a Pentium M 1.1GHz.

Linux mycomputer 2.6.17.4 #1 Fri Jul 7 20:43:16 CEST 2006 i686 i686 i386 GNU/Linux


And again, vmware with USB and the same bluetooth dongle does work and 
the old driver 2.x did work to.

How did you configure the PIN on your machine?
Do you have a passkey agent?

> the old driver 2.x did work to.

Do you know, that the PIN handling changed with BlueZ 3.0?

Short:
- pin is no longer in /etc/bluetooth/pin. Now is in /etc/bluetooth/hcid.con=
f.
- set "security auto;" and "passkey "yourpin";" in /etc/bluetooth/hcid.conf
  and try again.

I guess you do not see a timeout, but an rejection, since hcid has no PIN a=
nd
no passkey-agent, so it already knows, that it cannot authenticate the phone
and rejects it right away.

No, I use passkey in hcid.conf

I figured it out reading hcid.conf. Would be better to have something in 
the README or the ChangeLog or somewhere else. Is there some 
documentation I missed? I grepped for pin and pin_helper (to find some 
replacement for the old pin_helper).

See my answer above.

I tried both, security auto and security user (with kill and restart of 
hcid in between).

Why would hcid try to connect if there is no pin or passkey-agent? My 
phone gets connected.


Thanks,
Andreas

and this is only used for incoming connections. It is not the default
PIN for outgoing connection.

This was in the announcement of the BlueZ 3.0 series.

Leave it to "auto". It makes no sense to tune this parameter.

I don't see a PIN code or Link Key request in your hcidump. This is the
strange thing.

We send the SABM and then phone should answer with an UA. Are you sure
that channel 3 is the correct one?

What command are you using for the connection.

Ok, I'll remove this, as I don't want incoming connections.

Well... I didn't use the 3.0 version, blame me for not being up to date 
with each version :-)

Should this come from the computer or the phone?

Well, it did work with the old version of bluez. And my phone asks me to 
accept a serial connection. So this seems ok for me. Unless there is a 
change in the definition between bluez-2.x and bluez-3.x, it still 
should work.

I'll downgrade to a version 2.x, but this wont happen till this evening. 
What is the last version of the 2.x series, 2.25 or 2.26? Just to make 
sure, that the rest of the system still works as expected.


>MH: What command are you using for the connection.

I start minicom with /dev/rfcomm0 I guess, minicom only opens the port.

Thanks,
Andreas

Anyway... this might be the problem... how do I configure a pin_helper? 
I read the announcement of BlueZ 3.0, all I saw was the new ability with 
a D-Bus passkey agent. But how to setup? (I have to admit, I didn't read 
the D-Bus documentation, but a link would be nice).

Ok, just downgraded from 3.1 to 2.25. This version does work with my 
Linux Kernel 2.6.17.4

I tested 2.6.16.17, 2.6.17.2, and 2.6.17.4 all of them worked with BlueZ 
2.25, none of them worked with 3.1 (I did not test BlueZ 3.0).

If once paired with 2.25, it does work with BlueZ 3.1.



Below, find hcidump -X -V -t of this 2.6.17.4 with 2.25 (hcidump 1.30):

There is a "passkey-agent" that's compiled but not installed, in the hcid
subdirectory. Copy this into your path, then do

    passkey-agent --default 9999

before trying to pair the phone.

This worked for me.

Isn't this the same 'problem' with the agent to be for the incoming 
connections only?

No success... and now I have lost my pairing of the device I created 
with BlueZ 2.25 :-/

Thanks anyway for the hint :-)

I don't think so. However, my knowlede comes from lurking in this list
and playing with bluez-3.1 since ~3 days, so i might be wrong.

Can't you just initiate a pairing from the phone, so you can use the
passkey in hcid.conf? Maybe that's what i did, which let me claim it
worked ;-)

I'll play with this stuff more intensively next week and try to put together
some howto so we can all use our phones until kbluetoothd and co have caught
up ;-)

Hi again

I finally had time to test the 3.2 release of bluez. But I got the same 
result as described above with the 3.1 release.

I have to admit that I use a different phone now as my original crashed 
on me (not during a bluetooth session). But this shows me, that this is 
not necessarily phone dependent.

Any news on the developer front, what should I try to help resolving the 
problem?

Thanks,
Andreas
