[Bluez-users] Network Access Point - pairing problem

[Bluez-users] Network Access Point - pairing problem

[D.W.]

[-- Attachment #1: Type: text/plain, Size: 546 bytes --]

Hello,

I want to use bluez for a standalone network access point. All works fine(pand or dund), the thing is that the pairing doesn't work at first contact (client is a windows-pc). 

So I have to establish a rfcomm-connection manually(from the server side rfcomm connect 0 btad) first. This pairing works,  I disconnect and then I am able to connect the client to the NAT.

Does anybody know what's wrong and what I can do to make the pairing work without this manually initiated rfcomm-connnection ?

Thanks in advance,

Daniel

are we talking about security mode 2 or security mode 3? What kernel do
you use?

[Bluez-users] Network Access Point - pairing problem

[D.W.]

[-- Attachment #1: Type: text/plain, Size: 1343 bytes --]

Hi Marcel,
Thank you for your reply.
I use kernel 2.4.22 on an axis devboard82. The bluez stack is not the latest(PAN, SDP, utils, libs are still seperate packages), because I had problems porting later versions to the devboard.
But except the pairing problem at first contact it works perfectly.
Except the PIN (it's a static one at server side) there is no further authentification necessary.
Security mode 2 or 3? What do you mean? Can I check it?
When I try to connect to the server at first contact, I have to enter the PIN(client side) and after entering the right pin I get the message :"Authentification failed." 
Regards Daniel

you use a version where many fixes are missing.

What does "hciconfig -a" say?

Run "hcidump -x" and we can see what really happens.

you forcing a role switch (master role), but you aren't allowing it in
the link policy? Fix this.

The PIN code you entered is simply wrong. Try "BlueZ".

Hi Marcel,

it works perfectly now. Thank you very much for your help.
Where can I change this pin?
I assumed the pin is determined in hcid.conf.

for incoming connections it is read from /etc/bluetooth/pin and you have
to restart hcid after that. Actually I like to change that and let hcid
always read the PIN from that file if needed. So patches are welcome.

btw, what and where is the tried PIN code in that hex dump? B0 3A 4C 3D 0F 00
is obviously Bluetooth address of the remote host, so somewhere here
is the PIN code "05 42 6C 75 65 5A 00 00 00 00 00 00 00 00 00 00 00",
but how it is encoded?

you can use "hcidump -X" and you will see it. You can also read the
specification or think about what "05 42 6C 75 65 5A" maybe means ;)

[Bluez-users] AW: Re: Again dund

[Peter K. Martin]

Hi Marcel,
during my efforts to bring up a bluetooth connection, I'm always logged in
as root.

I checked with ps, here the result:

Linux-Notebook:~ # ps
  PID TTY          TIME CMD
 6340 pts/1    00:00:00 bash
 6348 pts/1    00:00:00 ps
Linux-Notebook:~ # hcid
Linux-Notebook:~ # ps
  PID TTY          TIME CMD
 6340 pts/1    00:00:00 bash
 6363 pts/1    00:00:00 ps

Then I initializedb the BT-function of my Toshiba-laptop:

Linux-Notebook:~ # dmabt
Linux-Notebook:~ # ps
  PID TTY          TIME CMD
 6340 pts/1    00:00:00 bash
 6462 pts/1    00:00:00 ps
Linux-Notebook:~ # hcid
Linux-Notebook:~ # ps
  PID TTY          TIME CMD
 6340 pts/1    00:00:00 bash
 6552 pts/1    00:00:00 ps

The next step was to use the hcitool:

Linux-Notebook:~ # hcitool scan
Scanning ...
        00:0B:CE:00:01:8F       Bluetooth-Modul
        00:02:EE:D0:49:44       PkM 6820

the BT-Modul and my handy (Nokia 6820) were detected. With sdptool I tried
to get the available services, at first of the BT-Modul:

Linux-Notebook:~ # sdptool browse 00:0B:CE:00:01:8F
Failed to connect to SDP server on 00:0B:CE:00:01:8F: Connection refused

and second my handy:

Linux-Notebook:~ # sdptool browse 00:02:EE:D0:49:44
Browsing 00:02:EE:D0:49:44 ...
Service Name: OBEX Object Push

    Version: 0x0100
etc........

At the moment I don't know how to get the daemon hcid running. I think if
this daemon runs, many of the problems are solved, aren't they?

Peter

reading the manual page of ps may help. Or try "ps x" ;)

You must run "hcidump -x" to see what is going on.

Leave it running. You will see something when you do something with the
HCI layer.

You don't need this at the moment.

Hi Marcel,
now I give you the responses of hcidump -x and I hope that you can give =
me a
hint for my next steps to the bluetooth connection.
At first I have to initialize the BT-function of my Toshiba-notebook by
dmabt, then I run the hcidump -x

With hcitool I'm scanning for BT-devices:

the L2CAP response failed with result code 3 and this means "Connection
refused - security block". The link key request is there and you reply
with a link key, but the connection fails. This means that your link key
that is stored on your system is wrong.

There is no easy way to delete a link key at the moment and so I think
the best way is to delete the file /etc/bluetooth/link_key and restart
your running hcid.

Regards

Marcel

now I have a new link_key with the right key :) :)

I'm able to connect via bluetooth

Linux-Notebook:/ # dund --connect 00:0B:CE:00:01:8F

Linux-Notebook:/ # dund --show
rfcomm0: 00:0B:CE:00:01:8F channel 1 pppd pid 6820

marvelous!! But now I need the next step. I want to use the
bluetooth-connection as/like an ethernet-connection as the BT-Modul =
gives me
the function of a switch and router with DHCP

I tried to get infos of the services provided, but no result:

you get these information from PPP.

If the public browse group is not supported you must do this with
"sdptool search --bdaddr 00:0B:CE:00:01:8F lan". Check the manual page
for more details.

Hi Marcel,
I'm not yet able to tell linux, that my bluetooth-connection is a
ethernet-connection. I have no idea how to manage this with PPP. With =
YaST I
tried to define the bt-connection as a networkcard - but it doesn't =
realy
work.

Linux-Notebook:~ # sdptool search --bdaddr 00:0B:CE:00:01:8F lan
Searching for lan on 00:0B:CE:00:01:8F ...
Service Name: Netzwerkzugang
Service RecHandle: 0x10000
Service Class ID List:
  "LAN Access Using PPP" (0x1102)
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 1
Language Base Attr List:
  code_ISO639: 0x656e
  encoding:    0x6a
  base_offset: 0x100

What can I do - ? - perhaps I have to install SuSE 9.2 ??!

Regards
Peter

I don't get your point. The ppp0 interface can be used and when the
routing information are right then this works. It is not different from
dialin with a modem.

The SuSE 9.2 will improve things, because the kernel, libs and utils are
up to date. However I don't know if that is the problem here. You should
remember that "LAN access using PPP" is deprecated and this stuff is all
PPP related. Look on the internet for more information.

Marcel

My telephone system works as DSL or ISDN system and has in addition a
bluetooth accesspoint. It also gives the abilities of a switch and =
router.
So, I tried to initialize via YaST on DSL or ISDN the connection via
bluetooth and expected to find ppp0 interface. But I didn't find it or =
it
doesn't exist already. My question is, how to establish a connection =
that is
able to use the ISDN or DSL functionality (router).

Regards
Peter
