[Bluez-users] connection to Motorola V525 fails

Hello list,

(resent because of the size limitation - please ignore the other mail
if it'll be approved later)

I can't establish a working connection between my computer(s) and my
bluetooth mobile, a Motorola V525. At [1] (sorry, only in German) a user
has described how to get that exact combination to work properly, but it
doesn't work for me.

So what does work? 'hcitool scan' finds my phone. 'sdptool browse
00:...' does list all the services on the phone, and I've found the
channel for the OBEX transfers which is 9. But using the obextool from
[2] fails. It does connect to the phone, and the following PIN
verification completes successfully. Afterwards the phone asks me if the
file transfer should be accepted, I hit 'yes' but that's it - no more
data flows between the two devices.

Now a bit about my system and the software revisions I've used. I've
tried with bluez-utils 2.4 through 2.7 (some of them Debian/unstable
packages, 2.5 from souce). I've tried kernels 2.4.24, 2.6.4 and 2.6.6
with the -mh1 patch. I've tried two different USB dongles, both are CSR
based, but I only have one available at the moment. Here's the output of
'hciconfig -a' for this dongle:

This is a device by Yakumo, one of the cheaper stuff sold around
here. The other dongle was built by Acer, but I don't know its exact
description. Both are USB dongles, obviously, and they're both
recognized flawlessly. At the moment I don't have access to any other
Bluetooth hardware - neither to computers with built-in Bluetooth
support, nor to other dongles or devices.

The remaining files are attached to this mail. The first is the
hcid.conf which is basically the default configuration. I've also tried
with enabling authentication and encryption, but basically I've left
both disabled for most of the tests.

The second file, 'motorola-v525-bluezutils24.dump', is the output of
'hcidump -t -x' during the call to 'obextool push test.jpg 00:... 9'. It
was done with bluez-utils 2.4 (older package from Debian/unstable). The
third is the same but with bluez-utils 2.7 (package from [3]).

I hope someone can make sense of the dumps. I can also provide an
additional dump made by the author of [1] which shows a successful
transfer to his Motorola V525.

Hopefully I haven't forgotten too much vital stuff. I'd appreciate any
help. Thanks.
