Hello

I'm using a Socket CF+ Rev E (Nokia chipset, hci v. 1.0b) in a Zaurus
called "collie" running bluez 2.11 to get network connection from a PC
NAP called "ebox" running bluez 2.10 with a USB dongle (CSR hci v1.1,
but similar problems happens with a ISSC hci v1.1)

Here is the strange problem I have. The devices see eachother in
hcitool scan, but l2ping from collie to ebox doesn't work. ebox can
l2ping collie. If ebox l2ping collie, during this I can l2ping
from collie to ebox, use pan, sdptool etc. (why ?!?)

If I press ctrl-c on either ebox or collie, the other one stops
l2pinging with a "Connection reset by peer".

Collie report "Protocol error" when I try to l2ping ebox without
running l2ping from ebox to collie. If I use the ISSC dongle (keyspan
bt-2a) it then simply says "Connection timed out".

If before pressing ctrl-c I have a pand connected, then they can
l2ping eachother as much as they want.

The problem of course is pand sdptool etc. doesn't work either.
Any suggestion ? I tried to change master\slave roles with hciconfig
hciN lm, but it didn't help

I'm sure this comes from the hci v 1.0b card from collie because other
devices work fine (they can l2ping, sdptool browse and pan connect to
ebox) while collie refuses to l2ping any other device (they can l2ping
collie !) but my cellphone.

hcid.conf from the server ebox:
options {
        autoinit yes;
        security auto;
        pairing multi;
        pin_helper /etc/bluetooth/givepin;
}
device {
        name "ebox.externe.net";
        class 0x020100;
        iscan enable; pscan enable;
        lm accept,master;
        lp hold,sniff,park,rswitch;
        auth enable;
        encrypt enable;
}


hcid.conf from the client collie:

options {
        autoinit yes;
        security auto;
        pairing multi;
        pin_helper /etc/bluetooth/givepin;
}
device {
        name "collie.externe.net";
        class 0x120114;
        iscan enable; pscan enable;
        lm accept;
        lp hold,sniff,park;
        auth enable;
        encrypt enable;
}


Even more bizzare : Collie can ping my s65 cellphone (after I type its
pin on the S65) so pin/l2ping should be fine.

root@collie:/etc/bluetooth# l2ping aa:aa:aa:aa:aa:aa
Ping: aa:aa:aa:aa:aa:aa from bb:bb:bb:bb:bb:bb (data size 20) ...
0 bytes from aa:aa:aa:aa:aa:aa id 0 time 79.80ms
0 bytes from aa:aa:aa:aa:aa:aa id 1 time 84.97ms
2 sent, 2 received, 0% loss
root@collie:/etc/bluetooth# l2ping cc:cc:cc:cc:cc:cc
Can't connect.: Protocol error

My S65 is aa, colie is bb, ebox is cc. Of course, ebox can l2ping the
S65

Collie is a Zaurus using bluez 2.11, ebox is a PC using bluez 2.10.
Another Zaurus with a CSR hci v.1. can do everything fine.

The only workaround I've found is :
. leaving a l2ping to collie running in the background, launched by
cron. Collie can then use pan, l2ping, sdptool etc.  normally

. using my reflashed dbt-120 dongle (hci v1.2) to which collie can
perfectly l2ping, using the very same hcid.conf files (!) - only the
btaddr is changing. Of course I can't leave my dbt-120 there - I need
it on another machine for its advanced hid features (boottime support
for mouse etc.

Any better solution or workaround would be appreciated. But I'd be
even more interested if someone could help me understand why all this
is happening. So far all my googling gave me no result.
