[Bluez-devel] can't add bnep0 to bridge pan0: Invalid argument

[Bluez-devel] can't add bnep0 to bridge pan0: Invalid argument

[R.M.M]

Hallo,

First of all I'm not completely sure if this is the right group to post
to but since I get no error messages in logs, I hope nobody will feel
offended.

I'm trying to create an NAP under kernel 2.6.18.2 (description from
http://bluez.sourceforge.net/contrib/HOWTO-PAN). I use an USB BT dongle
from Integrated System Solution Corp. and it's been recognised as follows:

~# hciconfig -a
hci0:   Type: USB
        BD Address: 11:11:11:11:11:11 ACL MTU: 678:8 SCO MTU: 48:10
        UP RUNNING PSCAN ISCAN AUTH ENCRYPT
        RX bytes:101 acl:0 sco:0 events:13 errors:0
        TX bytes:299 acl:0 sco:0 commands:13 errors:0
        Features: 0xbf 0xfe 0x8d 0x78 0x08 0x18 0x00 0x00
        Packet type: DM1 DM3 DM5 DH1 DH3 DH5 HV1 HV2 HV3
        Link policy: RSWITCH HOLD SNIFF PARK
        Link mode: ACCEPT MASTER
        Name: 'tempac'
        Class: 0x020100
        Service Classes: Networking
        Device Class: Computer, Uncategorized
        HCI Ver: 1.2 (0x2) HCI Rev: 0x1fe LMP Ver: 1.2 (0x2) LMP Subver:
0x1fe
        Manufacturer: Integrated System Solution Corp. (57)

The problem turn up when I try (after establishing connection) to add
bnep0 interface to pan0 bridge interface. After

~# brctl addif pan0 bnep0

I get:

can't add bnep0 to bridge pan0: Invalid argument

(bnep0 has IP 0.0.0.0 after ifconfig bnep0 0.0.0.0 and is up, though I
get no answer on ping which I could be a routing problem actually. Also
adding eth1 makes no problems).

As I said, no messages in logs, no more information. What's wrong?

Kind regards,

you have a dongle with an invalid BD_ADDR. Return that dongle and get
one which has a valid address. Dongles using this address can't be added
to a bridge.

Thanks a lot for this piece of advice. I wasn't aware there are
unlicensed dongles on the market. Unfortunately I can't give mine back:/
Are they somehow damaged or is it only a software problem?

I heard, that installing it under Windows changes the bt-address...
