Thanks for the quick reply! Attached is the 'hciconfig -a' in hciconfig.txt...

Bummer on the SCO support. I am looking forward to using it in an embedded linux based telematics system for vehicle hands free functionality. Anything I can do to help besides provide the 'hciconfig -a' output?

Regards,

Todd E. Johnson

Hi Todd,

this depends on whats your design. Do you use SCO over PCM or SCO over HCI? If your embedded device includes a PCM codec you can route the SCO traffic of the Bluetooth chip over PCM and you don't need the SCO audio support for the HCI USB driver.

[Bluez-users] bcm203x module causes kernel panic on boot

I'm a Gentoo user, and recently upgraded from 2.4.22-r5 to Gentoo Dev Sources 2.6.2. After suffering the following areas, I patched with the -mh2 patch, but they persisted.

I use a Belkin F8T001, and bluez-bluefw has always been a bit tempremental with me, so I jumped at the chance of using the bcm203x module in the kernel. Looking through the mailing list, I copied BCM2033-FW.bin and BCM2033-MD.hex to /usr/lib/hotplug/firmware/, unmerged bluefw gave things a try from a power off.

Below, I've pasted sections of the subsequent boot sequence. If the PC's turned on from power off (so the adaptor has no firmware already loaded, my PC will kernel panic, but continue booting and work okay, with the bluetooth subsystem working perfectly. Subsequent soft-reboots load Linux without any kernel panics, with bluetooth still working perfectly.

So, is this panic purely cosmetic, or is something fundamentally bad going on? In addition, could I suggest some documentation on the kernel help page for the bcm203x module to say where the firmware should be acquired/kept?

this is a problem with the early run of hotplug scripts and not a problem of the Bluetooth subsystem. Run the oops through ksymoops and post it to the LKML, because it belongs there.

Hi Todd,

Quoted 36 lines

I am attempting a simple proof of concept at the moment using the KDE Bluetooth Framework.

I have configured the local device class in hcid.conf to: "class 0x700408"

Then the KDE BTDialer needs the following set prior to using the app:

'hciconfig hci0 voice 0x0060'

Once the app launches it connects via rfcomm to the phone and initiates the followin AT commands (Here are the commands, with phone response)

AT+CIND=?
+CIND:
("battchg",(0-5)),("signal",(0-5)),("batterywarning",(0,1)),("chargerconnected",(0,1)),("service",(0,1)),("call",(0,1)),("roam",(0,1)) OK
AT+CIND?
+CIND: 2,5,0,0,1,0,0
OK
AT+CMER=3,0,0,1
OK
AT+CLIP=1
OK
AT+CIND=?
+CIND:
("battchg",(0-5)),("signal",(0-5)),("batterywarning",(0,1)),("chargerconnected",(0,1)),("service",(0,1)),("call",(0,1)),("roam",(0,1)) OK
AT+CIND?
+CIND: 2,5,0,0,1,0,0
OK
AT+CMER=3,0,0,1
OK
AT+BVRA=1

(As you can probably see above, the phone needs charging)

Quoted 7 lines

Upon initiation of 'AT+BVRA=1' the phone will ask "Say a Name or a Command", which I can not hear, nor can it hear me.

And I am attempting to use the "Hands Free" dialer. Vox seemed to work with 2.4, but a new 2.6.2 kernel seems to break this. I would assume that this means it is using SCO over HCI since I no longer hear the voice prompts from my phone, and the phone can not hear me.

I don't know what the problem with 2.6.2 and SCO over HCI and at the moment I have no time to investigate. If your Bluetooth chip is CSR based you can check the SCO mapping with "hciconfig hci0 revision".

Quoted 8 lines

Ultimately I wish to use the phone for hands free calls, but I will also use the phone for vehicle offboard connectivity using the "Dial-Up Networking" to obtain data for the vehicle. For example, Navigation data, E-Mail, Calendar, etc.

I am testing with a Sony Ericsson T608 (from Sprint). The phone works fine with a Jabra BT-200.

Quoted 6 lines

I'm moving towards following specifications defined at
http://www.ami-c.org/, but I am a little ways from achieving my final goal.

Sorry to seem completely clueless, but I am just beginning to use this functionality within my setup, and I'm still learning. Thanks for the information so far!

Go ahead and start playing with BlueZ :)

Regards

Marcel

I don't know what the problem with 2.6.2 and SCO over HCI and at the moment I have no time to investigate. If your Bluetooth chip is CSR based you can check the SCO mapping with "hciconfig hci0 revision".

If the SCO MTU for the device is too low prior to the URB submission, would it generate the -90?

It seems 90 is defined as EMSGSIZE in:

errno.h:63:#define EMSGSIZE 90 /* Message too long */

However, not remapped as other errors are in usb.h.

A quick grep of hci_usb.c reveals the error is generated when:

Line 275: err = usb_submit_urb(urb, GFP_ATOMIC);

Where a bit of the logic determines 'urb->transfer_buffer_length', then submits with the resulting error.

Am I way off here? I have attached the results of 'lsusb -v' to give more info. If you think I may be on the right track, I can _try_ to play with it a bit, but it may take me some time since I am a bit rusty...

Hi Todd,

Quoted 11 lines

If the SCO MTU for the device is too low prior to the URB submission, would it generate the -90?

It seems 90 is defined as EMSGSIZE in:

errno.h:63:#define EMSGSIZE 90 /* Message too long */

However, not remapped as other errors are in usb.h.

A quick grep of hci_usb.c reveals the error is generated when:

Quoted 8 lines

Line 275: err = usb_submit_urb(urb, GFP_ATOMIC);

Where a bit of the logic determines 'urb->transfer_buffer_length', then submits with the resulting error.

Am I way off here? I have attached the results of 'lsusb -v' to give more info. If you think I may be on the right track, I can _try_ to play with it a bit, but it may take me some time since I am a bit rusty...

I am not an USB ISOC expert, so go ahead and play with it. If you have a patch post it to the mailing list.

Regards

Marcel

Hi all,

I have been attempting to get SCO over HCI to work... I have a D-Link DBT-120 (B2). When I startup hcid, I was getting the following error message:

hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb de96e614 err -90
hci_usb_isoc_rx_submit: hci0 isoc rx submit failed urb de96e614 err -90

It appears this occurs since the hci_usb driver is picking a bogus endpoint with a wMaxPacketSize = 0 when submitting the urb.

Attached are a few files for assistance:

hciconfig.txt 'hciconfig -a'
lsusb.txt 'lsusb -v'
hci_usb_sco_debug.log.gz Debug logs from /var/log/messages
patch-2.6.2-tj1.gz a patch

The attached patch includes patch-2.4.24-mh2, a fix for the error, and a few minor fixes so the kernel can build when debugging is enabled...

This does not fix SCO support, It simply assists in getting an endpoint where wMaxPacketSize != 0.

Here is the critical part, or what eliminates -90:

<patch>

drivers/bluetooth/hci_usb.c +0 -0
diff --unified --recursive --new-file linux-2.6.2/drivers/bluetooth/hci_usb.c linux-2.6.2-tj/drivers/bluetooth/hci_usb.c

@@ -833,7 +834,7 @@

#ifdef CONFIG_BT_HCIUSB_SCO
case USB_ENDPOINT_XFER_ISOC:
- if (ep->desc.wMaxPacketSize < size || a > 2)
+ if (ep->desc.wMaxPacketSize <= size)

						break;
					size = ep->desc.wMaxPacketSize;

</patch>

Now that the error is gone, SCO still is not working. Since I enabled debugging with this patch, I was able to capture additional data to assist someone whom knows much more than I in fixing the SCO over HCI_USB.

If I'm completely clueless, please disregard, and sorry to waste your time! Thanks in advance!

Regards,

Todd E. Johnson

The attached patch includes patch-2.4.24-mh2, a fix for the error, and a few minor fixes so the kernel can build when debugging is enabled...

1,$s/patch-2.4.24-mh2/patch-2.2.2-mh2/

Sorry, I meant to say patch-2.2.2-mh2... Sorry about any confusion this may have caused...

Howdy,

Using the patch and information I sent a few days ago, I attemted a SCO connection with a Sony Ericsson BT enabled handset. I attempted to use the KDE BT Dialer from the KDE Bluetooth Framework.

Attached is a file 'hci_conn.txt' which shows the device actually has a SCO connection, however I can not hear anything like I previously could with 2.4.22. I also included 'hciconfig hci0 revision' and 'hciconfig hci0 voice' in this file as well.

While I was attampting the connection, I did a 'hcidump -w hci_dump.raw' and have included it with this mail also.

Is the previous, as well as this, information helpfull?
