Hi,
I have some problems with sdp on a Intrinsyc Cerfcube 255
(http://www.intrinsyc.com/products/cerfcube/) running a Linux 2.4.19
kernel patched with the mh17-patch (and some platform specific patches).
The problem is that I can't get to discover anything on the device. I
have tried with two mobile phones, and a laptop running RH 9.0.
From the laptop I either try 'spdtool browse bdaddr' or 'sdptool search
SP' after adding SP service to the SDP record of the Cerfcube. I am able
to browse the service record of the mobile phone, but not the Cerfcube.
The output could be: 'Failed to connect to SDP server on
00:0A:94:00:20:2A: Resource temporarily unavailable'. Other reasons I
have experienced are: 'Host is down', 'Connection timed out', and
'Connection refused'.
My final goal is to make a connection (SP profile) between a Midlet
running on a Nokia 6600 and the Cerfcube. I have tested this setup with
the laptop and the phone and it works. But this will only work if
service discovery works.
At first I thought that maybe the problem was caused by using old
versions of bluez on the Cerfcube, but I have just cross-compiled and
installed bluez-2.8 (lib and utils) and the situation is the same.
Here's the output from 'hcidump -x' from the Cerfcube when trying
'sdptool browse' from the laptop.

I'm using a USB bluetooth dongle for both the Cerfcube and the laptop.
So, what to do next?
Best regards, Rolf.

this can happen sometimes. It is mostly a chip problem.

Can't help you here until someone sends me a Cerfcube and I can do my
own tests.

Marcel

Just tried on more time, and I was able to discover the SP service of
the laptop.

I have tried a couple of more times from the Cerfcube to search for SP
on the laptop and also on my Sony Ericsson T610. Approx. 4 out of 5
times the search will succeed and otherwise I'll get the error message:
"Service Search failed: Connection timed out".
Searching for SP on the Cerfcube from the laptop does (still) not work.

and it is still the same problem. One side sends the config request, but
the other don't receives it. Try to browse from the Cerfcube a service
on your laptop's SDP database.

Uups, guess I'm not using my brain for thinking right know.
No the mh14 kernel patch does not fix the SDP browsing problem.

Well I can understand that. When rereading my post I can see I have
expressed myself rather vague.
I meant:
Two months ago I initially tried the mh17-patch (as this was the
newest). SDP browsing did not work. I also tried the mh13- and
mh15-patch but that did not help. SDP browsing still non-working. I then
went on with other projects.
This time (this week) I decided to try again. Again using the mh17
kernel patch, but now with the bluez-libs-2.8 and bluez-utils-2.8. Still
SDP browsing is not working on the device.

:-) (should have read the manual better)
The other dongle I have available has HCI 16.4 firmware. If it is of any
help here's the output from "hcidump -x -t" from the laptop (browsing
the Cerfcube using the HCI 16.4 firmware dongle). I'm still using the
mh14 kernel patch.

This can happen. You won't need the bfusb.o driver. Try a clean compile.

You can use "hciconfig hci0 revision" or look it up on my CSR page.

I think that this change "Fix non-blocking socket race conditions" could
have caused some problems. One part of it already has :(

Yes (but I haven't tested much), although I get this error message when

Sorry for being a little bit puzzled now. How do I see what the firmware
version is for my current dongle? I translate the HCI Rev hex number to
469 in decimal so should I just put the decimal point after the 4?
At the moment I also have another USB dongle available and the output
from "hciconfig hci0 version" is
[root@xscale3 /root]# hciconfig hci0 version
hci0: Type: USB
BD Address: 00:0C:76:B1:05:74 ACL MTU: 192:8 SCO MTU: 64:8

Which give HCI Rev number 525 in decimal. Are my dongles really that
antique?
Final question. I'm curious about why I should try the mh14-patch? Do
one experience subtle differences between the output from hciconfig?

Well that could definitely account for some very-hard-to-find bugs, so I
hope that's not the case :-) Thanks for your help so far!

Was only an idea. In general the BlueZ should now be endian safe, but
you never know for sure ;)

After compiling a new kernel and reflashing:
[root@xscale3 /root]# hciconfig -a

With regards to endianess, good quiestion. After googling around I
actually think it can be both. But I made a small program testing it and
it said little endian.

the problem is that this "Config req" request never reaches the other
side. And because of that the laptop sides sends a "Disonn req" after
some time.

Try using 2.4.19-mh14 and show us the output of "hciconfig -a" on your
Cerfcube. Is the Cerfcube a big endian machine?
