CSR firmware question...

[Jean Tourrilhes]

	Hi guys,

	A few questions regarding CSR firmware : what's a commonly
available BT USB dongle with a recent CSR firmware.

	Long story :
	I'm hitting various bugs with the CSR firmware in my D-Link
USB dongles (0x1bb), where I can easilly deadlock the dongle. My 3Com
dongle, which has a more recent firmware (0x20e), behave much better,
but not perfect.
	D-Link doesn't provide a firmware updater, but, beeing
fearless, I tried to firmware upgrade a D-Link dongle and ended up
with a dead dongle (can't even put back the original firmware on it).
	From the release notes, the latest CSR firmwares have zillions
of bug fixes. I really wonder how I can enjoy the bug fixes.

	Thanks in advance...

	Jean

P.S. : Marcel, do you have a version of btdfu that can write the
firmware image to the dongle ? Or some documentation ?

as I know there are only dongles with HCI 16.14 firmware available.

The D-Link dongle DBT-120 (Rev B3) can be updated using the Apple
firmware update file. After that it will be HCI 18.1 with default boot
mode set to HID. Maybe other revisions of the D-Link dongle don't work
and I already put some of dongles to death while playing with firmware
upgrade.

I never announced the new version of the btdfu, but now as you asked for
it, here it is:

	http://www.holtmann.org/linux/bluetooth/btdfu-0.3.tar.gz

Use it at your own risk, because you can kill your dongle !!!

Read what the CSR guys had written about signed firmware and that it is
not possible to move firmware from one manufacturer to another !!!

	This is exactly what I did. I have a rev B3, and I used Apple
file.
	What do you mean default boot set to HID ? I look similar to
what I'm seeing.

	Yep, seems easy.

	Actually, I realised that I can't even use that, the dongle no
longer has a control pipe. Grrr....

	Yep, I read that, I won't comment to stay polite.

try running hid2hci :)

If this does not work, show us /proc/bus/usb/devices.

	Try, and it won't work, the device doesn't even have a control
pipe anymore. Dead.

as far as I know, every USB device has a control endpoint.

your firmware update must be successful, because this looks like a
dongle with HCI 18.1 firmware in HID mode. Use hid2hci. It must work.

	Found the reason. Under 2.6.X, hid2hci doesn't work. On the
other hand, works fine in 2.4.X. And of course need to be done every
time I plug the dongle.

I just checked it and it works under 2.6. I don't know what's wrong with
your kernel or system?

There exists a PS key for the boot mode that you can change to always
boot up the dongle in HCI mode.

It appears as a HID device instead of a Bluetooth device. Presumably so
that the PeeCee BIOS can use a Bluetooth keyboard as if it were a USB
keyboard, and do its emulation thing to make _that_ appear as a PS/2
keyboard....

Try running 'hid2hci' from recent bluez-utils. It should 'convert' it
back to being an HCI device again.

Is btdfu app USB only?

A quick skim through the source leads me to believe it is. Will their be
a UART one?

Hi Rod,

yes, it is USB only.

I have no plans to do this and even if I find the time for it, I won't
do it, because I don't need it. Actually the upgrade support of version
0.3 is only there, because a company paid me for writing it.

Re: [Bluez-devel] CSR firmware question...

[Carl Orsborn]

Hi, Jean,

Can you reveal what you're doing with the CSR device when
you suffer deadlock?  We may recognise the symptoms, and possibly
know of a workaround or of fixed firmware.

Build 0x1bb is "HCI 15.3", released in August 2002.  Build 0x20e
is "HCI 16.4", released in October 2002.  HCI 16.4 introduced
basic scatternet support and fixed some issues in HCI 15.3.

HCI 16.14 (build 0x33d) was published to product manufacturers
in April 2003.  This fixed a handful of issues in HCI 16.4.  You
may be able to get hold of this, but I have no knowledge of
what firmware D-Link have tested with their hardware and have
subsequently (signed and?) published.

If your hardware is suitable (i.e., if it has an 8 Mbit flash
device), you may be able to load HCI 18.1 or HCI 18.2; these
support BT 1.2.

Carl

	Trivial deadlock :
	initiating a connection to a device within 80ms of receiving
incomming connection from same device. Unknown if bug is in fw or
stack, but firmware deadlock.

	Intermitent failure :
	Initiating connection (page) within 20ms of bringing HCI
device up. Sometime it works, sometime it doesn't.

	None, as far as I can see. That's why I was looking at other
vendors.

Is the incoming connection a connection request from the remote device, or a
connection complete?

If the latter, is it from an auto-accept filter, or from your host 
accepting the connection?

This feels as though it might be from an LMP collision - one of the 
nastier elements
of the baseband specification.  When collisions occur (two devices 
initiate LMP
transactions at the "same" time) the firmware sometimes defends itself 
with lengthy
timeouts, but I'm unaware of any resulting deadlocks in current firmware.

I assume "bringing HCI device up" means your local BT device.  The CSR
device should be ready for a single HCI command as soon as the host 
transport
is established, though to signal readiness, the device sends a NOP 
command_complete
to the host when it starts.  I don't know if your host code waits for this.

It's fairly common for host stacks to use an HCI Reset command after a 
device
has started.  I don't know if your host code does so, but this shouldn't 
matter.

You say the device sometimes doesn't work.  How does the host perceive
the command doesn't work?  Failure to respond, or command rejected?
