[Bluez-users] Belkin F8T002 PC Card problem with Bluez

[Bluez-users] Belkin F8T002 PC Card problem with Bluez

[Alexandre Jousset@NL]

	Hi all,

	I am trying for 3 days to configure this card on my laptop. I am 
running Mandrake 9.2beta with a hand-compiled kernel 2.4.22.

	First, to make my card recognized by the hardware, I have to enter 
"cardctl insert". It does not do this automatically. Is this normal ? 
But when I remove the card it beeps and knows that the card is no more 
here. But this is not the most important problem... Here it is...

	I succeeded to know what to do to have the card recognized by the 
kernel (compile with CONFIG_SERIAL as a module) and now when I do the 
"cardctl insert"command, I have the new /dev/ttyS4 device that appears. 
OK. But then, when I try to hciattach it with "hciattach /dev/ttyS4 any 
flow", the CPU is loaded and in the /var/log/messages logfile is 
appended a lot of lines, all the same, saying "h4_recv: Unknown HCI 
packet type ef", with the last "ef" changed with "0f", "18", etc... each 
time a different hexadecimal number.

	I patched the drivers/char/serial.c module source and the 
include/linux/pci_ids.h to have the chip recognized by the serial module.

	Output of lspci -vv is :

	This is my first try with bluetooth so if I made something wrong, 
please tell me...

	So, why is my log full of unknown HCI packets ? Thanks in advance.

try "hciattach /dev/ttyS4 bcsp".

Send the patch (diff -urN) to the mailing list.

Re: [Bluez-users] Belkin F8T002 PC Card problem with Bluez

[Alexandre Jousset@NL]

	Hi all,

	I tried with setserial to set ttyS4 to irq 3 (it gave me this value
once when doing setserial autoconfig) -> hang.

	I tried with setserial to set port to 0x4010 (as listed as second I/O
ports region with lspci), no error but hciconfig hci0 up fails with timeout.

	With the original setup (irq 11 and ports at 0x4000, as the serial
module set them and the config that put the lines h4_recv: Unknown HCI
packet type xx), I wrote a small C program to read ttyS4 and print the
numbers on stdout. I noticed some reccurrent value so I told the program
to put a newline before each value 18. The output is :

-----------------------------------------------------------
18 20 e8 36 be f0
18 20 e8 36 be f8
18 20 e8 36 be f8
18 20 e8 36 ef 0f
18 24 e8 36 ef f0
18 24 e8 36 ef f0
18 20 e8 9b be f8
18 20 e8 36 ef 0f ff
18 20 e8 36 ef 0f ff
18 20 e8 9b be f8
18 24 e8 36 ef f0
18 20 e8 36 ef 0f
18 24 e8 36 ef d0
18 20 e8 36 ef d0
18 20 e8 9b be f8
18 20 e8 9b be f8
18 20 e8 9b be f8
18 20 e8 36 ef 0f
18 20 e8 36 ef 0f
18 20 e8 36 ef 0f
18 20 e8 9b be f8
18 20 e8 36 ef 0f ff
18 20 e8 9b be f8
18 20 e8 36 ef 41
18 20 e8 36 ef 0f
18 20 e8 36 ef 0f
-----------------------------------------------------------

	So that must mean something but I don't know what. The first octet is
always 18, the second is either 20 or 24, the third always e8, the
fourth either 36 or 9b, the fifth either be or ef, the sixth either 0f
or d0 or f8 and when it is 0f it is sometimes followed by ff...

	Any clue ?

	Thanx !

I think this is the BCSP protocol, but with wrong terminal settings or a
wrong baud rate. Try to attach your device with BCSP and different baud
rate settings and replug it every time to have a clean state.

[Bluez-users] Re: Belkin F8T002 PC Card problem with Bluez

[Will Partain]

(I am picking up a thread about this card from back in September.)

To recap, with Belkin F8T002 card plugged into a Presario
908EA laptop running a modified current-RH9 kernel [added a
few lines as Alexandre Jousset suggested earlier in this
thread]. Then with...

   # /etc/rc.d/init.d/pcmcia restart 
   Shutting down PCMCIA services: cardmgr modules. 
   Starting PCMCIA services: cardmgr. 
 
In the syslog for that, you see...

    /sbin/hotplug: invoke /etc/hotplug/pci.agent () 
    /etc/hotplug/pci.agent: ... no modules for PCI slot 02:00.0 

Anyway, it's there:

    # cardctl ident 
    Socket 0:

      manfid: 0x0279, 0x0001 
      function: 2 (serial) 

An 'hciattach' then "works", where "works" is defined to
mean "something happened".  The simplest form
(hciattach /dev/ttyS4 any) spews nonsense, as was seen
earlier in this thread.

The glorious Marcel suggested 'hciattach /dev/ttyS4 bcsp'
(which simply replies: "BCSP initialization timed out").  He
further suggested fiddling with baud rates and the like;
neither Alexandre not I have had any luck with that (it
still just times out).

So: Has anyone made further progress on this device and/or
has any suggestions?  (I am serially incompetent and short
of time, but I'll try to help if I can.)  Thanks and regards
to all,

Will

	I did not try again but I can tell that, according to my experience and
what Marcel told me, the problem seems to reside on an incorrect setting
in the serial communication. So it seems to be bcsp but with other
settings. If we knew what sequence of bytes the bcsp protocol sends it
would be possible to check in the log, when attaching without bcsp but
with an other setting that 'any', to see which is good. Hm this is not
very clear but people with knowledge of this can understand ;-) In fact,
if it were possible to set the parity settings and other settings in
command line it could be simpler to try which combination is the good one...

	For the moment I can not do this because the serial module in my kernel
(the one in Mandrake 9.2) does not recognize the card. When I tested it
was with a specially compiled kernel with serial.c as a module and I was
obliged to rmmod the module to insmod it after. The problem is that I am
unable to get all modules necessary to recompile the Mandrake kernel (it
tells me things like supermount not loaded and I don't find this
module)... Anyway...

	My 2p.

Alexandre Jousset.
