[Bluez-devel] dfutool problems

All,

I recently ran "dfutool archive foo" on my IBM bluetooth adapter
(Broadcom) thinking it would save my firmware to the file "foo".  It
created a zero-length file, said that the operation timed out, and
exited.  Ever since, by bluetooth adapter has been stuck in DFU mode:

# dfutool archive foo
Available devices with DFU support:

         1) Bus 003 Device 034: ID 0a5c:2000 Interface 0 (DFU mode)

Select device (abort with 0): 1

Firmware upload ...
Can't upload next block: Connection timed out (110)

from dmesg:
usb 3-1: Product: Broadcom Bluetooth Download Device

Does anyone know why it did that and how to get the adapter out of DFU
mode?  I don't want to have to buy a new adapter... :)

Thanks.

Jarom Hatch

the Broadcom ones fail for no reason. Seems that their implementation of
DFU is buggy. I have seen that before.

However there is no tool to get it back into normal. It is not that
complicated, but you have to poke around the source code of dfutool for
that.

Regards

Marcel
