Audio & Bluetooth
Hi list,
I have a question: for my mobile I use an HAMA Bluetooth headset. If I buy a bluetooth PCMCIA card for my notebook, will I be able to use this headset with this card? recognized as a second soundcard? as a normal headset for my integrate soundcard? recognized by my software phone clients? If I buy an USB bluetooth device, would it be the same? better?
I'm running a Debian SID kernel 2.6.
Thanks for reply

see bluetooth-alsa.sf.net to make the headset appear as another alsa sound card.
i haven't been able to use my cf bluetooth card (in pcmcia slot) since 2.4 but i know people are working on fixing that. almost every new usb adapter works... i was pleasantly suprised recently to find that compusa's "generic" class 1 usb adapter worked right away when i plugged it in.

actually this is not an easy to answer question. First thing is that you should get a Bluetooth device with a CSR chip and at least HCI 16.x firmware on it. The second is that it must route the SCO traffic through the HCI and via a PCM. Then it should be possible.
I would prefer a USB dongle, but there are problems with the driver that are not finally solved yet. PCMCIA cards may have the problem that the bandwith is not high enough or you may get bit errors.
Look at bluetooth-alsa.sourceforge.net and the mailing list archives for more details.

Marcel

How to identify version 16.x or higher ? hciconfig -a only gives a hexadecimal value, that not really gives me get a clue on the firmware version.

Must be blind. Anyhow, i guess this doesn't sound good for sound:

SCO mapping: PCMI have problems with no audio on this dongle. So i take it, that it might be the oldish firmware.

12.7 is prehistoric, unfortunately. The last release for BlueCore01 was 16.something, then we stopped supporting it. If you want further improvements after that, you should get a new dongle. All new ones should have at least BlueCore2 in them (we only have one BlueCore01 customer left and they don't make dongles).

A bit OT, but I tried that on my Sony Picturebook (C1VFK) and got
=====================================
tim@william ~]$ sudo hciconfig hci0 revision
hci0: Type: USB
BD Address: 08:00:46:21:58:29 ACL MTU: 128:8 SCO MTU: 64:8 Build 66
Chip version: BlueCore01b (ES)
=====================================
I guess that means the chip in the in-built Bluetooth is pre-pre-historic.
Is there any hope of upgrading in such a case? Eg could upgrading the BIOS upgrade the BT chip too?
It's really only an academic question,
as Bluez/gnokii are perfectly able for what I want.

this is a pre HCI 11.2 firmware and my oldest card is a Xircom CBT one with build id 101.

No. This is always done separately. However this boot loader shouldn't check the signature of the DFU file and so in general you can try to load a HCI 16.4 on it. Of course at your own risk. Does Sony provide an update for this notebook?

Marcel

Congratulations, this is the oldest chip I've ever heard of in the wild. The "ES" chip is an engineering sample, even before the full production run of BC01b. I'm not 100% sure these are properly supported by the later BC01 firmware, so I wouldn't recommend upgrading the firmware, even if you find away, unless you're pretty sure you can get back.

as far as I know only the Xircom cards are the other ones with beta firmware there were out there in the wild, but the C1VFK is really the oldest one.
The ES is interesting, because once I flashed a BC02 ES with a newer firmware afterwards the ES was gone ;)
However if anyone has old Bluetooth hardware and has replaced it with newer one I would be very happy if they donate these old devices to me, because I collect them. Something like a Bluetooth museum.

Marcel

on hciconfig hci0 revision: "SCO mapping: PCM" is good ? And "SCO mapping:

Is there anyway that can be done to this in regards to audio ?

the SCO mapping HCI is the right one, because for the PCM you need access to the PCM interface on your Bluetooth chip and normally you can't access this on an USB dongle.

For a CSR chip the SCO mapping can be changed.

How can the mapping be changed, if I may ask. I've been looking around and the only material that i found of it, is actually that you stated at some point, that they have to match, but not how it can be changed.

It must be set to SCO over HCI to get it working. Most dongles sold now uses this setting by default. Some older don't. So this is a CSR chip and all settings are in the persistant storage (PS). So you only have to set the PS key for this one to HCI instead of PCM.
Said this there is a Windows program called pstool that can do this for you, but it is not freely available. This is CSR specific and if you dig deep enough into the source code of BlueZ and also the OpenBT project, you can get the knowledge on how to change it. I don't provide a tool for it and I also won't answer any further questions about this.

Marcel
