[Bluez-devel] Trouble with bluetooth headset

[Bluez-devel] Trouble with bluetooth headset

[Clark Pope]

I have a colleague that is stuck trying to get a bluetooth headset working. 
The system is montavista linux 2.6.10 on x86 for development and PPC for 
deployment. Below is his request to me. Any help/guidance you can provide is 
greatly appreciated. Also, if you can recommend a known good combination of 
headset and usb dongle that has working drivers for PPC405 (Xilinx SOC) it 
would save us the trouble of fixing this one. Thanks, Clark

-----

Well, I'll accept any help I can get. As I understand it, Montavista gave us 
Bluetooth packages as not officially supported software, but I would feel 
free to ask them questions if I thought their software was the issue.

With the headset device, I think the problem is with the alsa-bluetooth 
connection. I am getting my guidance from:

http://bluetooth-alsa.sourceforge.net

I am using the "legacy driver" approach with the snd-bt-sco driver and the 
btsco/btsco2 app. One issue involves whether configuration files are set up 
so I don't have to enter the passkey. Normally this is done with a Gnome 
(desktop) app, and that can't work on the 9479. Some of the messages on the 
hcidump trace lead me to believe I don't have all the configuration files 
set up correctly - to get access without a passkey, on the correct RF 
channel, etc.

With hci0 set up, aplay shows the headphone connection:

# aplay -l

**** List of PLAYBACK Hardware Devices ****

card 0: Headset [BT Headset], device 0: Bluetooth SCO PCM [BT SCO PCM]

Subdevices: 1/1

Subdevice #0: subdevice #0

When btsco2 initializes, it tries to connect to the headphone, and there 
seem to be errors in the output (I'm not sure what all of it means, but the 
"connection refused" message seems significant):

More later - when I return from vacation I'll spend more time on it. Any 
help I can get would be appreciated.

the 2.6.10 kernel is highly outdated. Switch to the upcoming 2.6.22
kernel. We are not supporting these old kernels and I am not doing any
backports for it.

Marcel

Re: [Bluez-devel] Trouble with bluetooth headset

[Clark Pope]

So you think the problem shown in the log is related to the kernel version, 
not just some configuration issue? I think the bluetooth part is working it 
just rejects the connect for some reason. Thanks

I don't even know, but I am simply not chasing any bugs from people that
don't run at least a reasonable new kernel. And 2.6.10 is ancient. If
someone else wanna look at it, it is fine by me, but I won't until you
have this issue with a recent kernel and latest bluez-utils.

Regards

Marcel

Guess I should clarify, the original base was 2.6.10 but montavista has 
about 1200 patches applied to it so I'm not sure what the true rev level is 
compared to the stock kernel tree. But the other bluetooth devices seem to 
work okay. Just seems something odd particularly for audio and this 
authentication business with the headset. Any suggestions at all are 
appreciated. -Clark

Re: [Bluez-devel] PS3 compatibility list?

[Clark Pope]

[-- Attachment #1: Type: text/plain, Size: 343 bytes --]

I wonder if there is a good hardware compatibility list for bluetooth 
devices under linux on the PS3? The distribution I have is FC6.

Thanks,
Clark

Re: [Bluez-devel] PS3 compatibility list?

[Simon Ruggier]

As a Linux user, and not someone particularly knowledgeable about
Bluetooth, I would guess that it's most likely that either everything
works or everything is broken, rather than some things failing to work
but not others.  If my guess is accurate, then a list wouldn't be very
useful.

Bluez works on the PS3 under YDL linux. Do an apt-get.
