[REGRESSION] Natty: bluetooth phone connection not working properly

[Simone Tolotti]

Binary package hint: bluez

After upgrading to Natty I am missing some essential features from the bluetooth stack.
I can authenticate my phone but I can't configure it for DUN networking.
Also I can't browse files on the phone or send files to it.
All those actions worked without issues on Maverick.

hcidump log about trying to configure device for DUN networking, trying to browse files and trying to send a file to the phone.

[Krishna (krishnab)]

I am using Ubuntu 11.04.. I can send files to the device.. But I cannot browse the device ....

[Everthon Valadão (valadao)]

If I do a pairing with my PC and phone, at the first time I can successfully send files from my phone to the PC (and vice-versa). I can also browse the phone and use it as a bluetooth modem. After restarting the PC, if I try to send a file from my phone to the PC, I get a message "Connection FAIL". BUT, if I try it again, it succeed!

So, maybe the "bluetooth obex daemon" (or something like that) isn't running or ready at the first attempt, but at the second trial to send a file it is. However, the networking connect doesn't work anymore, unless I remove and redo the pairing process.

So, if someone could instruct me what log files and debug info do you need to try to fix this problem, I'm happy to provide them.

This is reported against an old version of Ubuntu and many things has changed since then. Because of that we won't fix this issue however if this behavior repeats on a modern version please fill a bug report against it and we will take it from there.
