Ok.

The problem is that I have laptop and usb-bt dongle, I can initiate any
connection with any device or pairing from laptop, but can't initiate connection
from devices to laptop. Device (Pocket PC for example) simply can't get list of
services from laptop. But! When I use the same dongle with desktop machine
everything works well (with the same /etc/bluetooth/ config).

On desktop I use 2.6, but here I have to use 2.4 because sound driver works only
with it.

think about installing bluez-libs-2.7 and bluez-utils-2.7. In that case
you don't need the bluez-pan or bluez-sdp anymore, because they are
deprecated.

Run "hcidump -w <file>" as root and send us the resulting file after you
tried to connect from your PDA.

Marcel

this looks like a problem in the sdpd. Please install the one from
bluez-utils-2.7 and try again. Is your laptop a big endian machine?

there must be a bug in the sdpd that we don't know of, because the sdpd
has to answer the SDP SS Req instead of disconnecting. However I have no
idea why this happens. Please use another device to browse the SDP
database of your notebook.

I read something about non working select() on LKML, but I thought this
was 2.6. However you should update your kernel to the latest -pre from
Marcelo and or use the latest stable with my -mh patch.

[Bluez-users] rfcomm correction

[Swarup Mohalik]

Please ignore my earlier mail. There was a small but serious typo.
 
I have bluez with bluez-utils-2.7 on two RH 8.0 systems (lx1 and lx2).

When I start rctest -s on lx1 without starting rctest -r on lx2, lx2 hangs
and I have to switch it off and on to restart. This happens EVERY TIME
I try this.  (In the previous mail, I had messed up the -r and -s)

This does not happen when I run l2test in any way. Does it prove that
there is a problem with RFCOMM? I have not seen this problem in
the mailing list. If I have missed it, please inform.

I have not tried the rfcomm transfer the other way because I share lx1
with others.

Thanks in anticipation,
Swarup

as I said before, we need to know what kernel you are using and if
possible, what's the output of "hcidump -x" as root.

Marcel
