[Bluez-users] experience with TDK PCMCIA Bluetooth Card (goBlue)?

[Bluez-users] experience with TDK PCMCIA Bluetooth Card (goBlue)?

[Lars Vilhuber]

Question:
    after searching the list, I see few comments on the TDK PCMCIA 
Bluetooth card. Currently, mine is *not* working, but before I go 
through (upgrade kernel, patch kernel, etc.) sequence, I would like to 
know if anybody has actually got it working.

Symptoms are a collection of

bcsp_recv: Short BCSP packet
bcsp_recv: Out-of-order packet arrive
bcsp_recv: Error in BCSP hdr checksum

which I have seen reported for some cards before, but for which I 
haven't a solution reported.

The above occurs for any data transfer (OBEX or PPP) of any considerable 
size, and culminates in the driver "resetting" the card, and the 
transfer failing.

This is irrespective of using 'hciattach ttyS14 <speed>' or 'hciattach 
ttyS14 bcsp' or 'hciattach ttyS14 tdk'.

OS/Version:
SuSE 9.2, kernel 2.6.8-24.11-default #1 Fri Jan 14 13:01:26
bluez-utils-2.10-15
bluez-libs-2.10-2

so in general your card gets detected as serial port and normal stuff
like "hciconfig -a" is working?

The last time I tested this kernel I haven't found any problems, but you
should think about a kernel update. However I just put in my IBM card
and a Com1 card and both lock up my SMP machine when I start hciattach.
I don't have time to really check what is going wrong here. Do anyone
have serial based Bluetooth cards running with a SMP kernel.

Regards

Marcel

... after some filling up of /etc/pcmcia/ config files... yes. The lists
helped on that:

config.opts AND bluetooth.conf (one may be redundant):
card "TDK goBlue PCMCIA Bluetooth Adapter"
~  manfid 0x0105,0x4254
~  version "TDK","Bluetooth PC Card II","",""
~  bind "serial_cs" class "bluetooth"

and adding an elif condition in /etc/pcmcia/bluetooth conditional on MANFID.

| like "hciconfig -a" is working?

that yields:

I should note that most everything works in principle:
	- I can browse services of other devices using this card

	- I can *not* receive/send larger data chunks (jpeg)
~          or streams of data (PPP connection)

It all breaks apart at the short packet/bcsp/etc.

this looks like a new generation of the card. Please post the output of
dump_cis.

Sounds like a bug in the BCSP driver. Maybe this card uses a variant of
BCSP that the driver can't handle.

I believe the right link is

http://www.tdksystems.com/products/intro.asp?id=3

I bought it here:

http://www.expansys-usa.com/product.asp?code=106260

 > Please post the output of

Socket 0:
   dev_info
     NULL 0ns, 512b
   manfid 0x0105, 0x4254
   funcid unknown [post]
   vers_1 7.1, "TDK", "Bluetooth PC Card II", "", ""
   config base 0x00f8 mask 0x000f last_index 0x04
   cftable_entry 0x03 [default]
     [rdybsy]
     Vcc Vnom 5V
     io 0x01e0-0x01ef [lines=8] [8bit] [range]
     irq mask 0xffff [level] [shared]
   cftable_entry 0x04
     io 0x0000-0x7fff [lines=15] [8bit]

Looks like it is new...

Let me know - if it is new, I will just give it to a Windows-only 
colleague - I need it on a machine where I do not want to run 
non-distribution kernels (I would on another machine, but that's not a 
laptop...), but let me know either way. I'll be happy to run a couple of 
tests until then.

according to my list of CIS entries this is the second generation of the
TDK card. The first one was the same as the IBM Card II and this is the
one that I have and that I tested. There are now two possible problems.

One is that they change the UART that the use. What is dmesg telling
about the serial device that is created when you plugin the card?

The second is that the BCSP setting is different for this card and that
our implementation has a problem with it. There are lot versions of BCSP
around, because the initial one created to much load on the chip where
the host protocol is running (there is not always a Pentium available).

Since I haven't written the BCSP code and I don't have this card for
testing, I can't give you a good advice or testing plan. The PCMCIA
cards are always a little bit tricky. However using the latest kernel is
mostly a good idea. Try 2.6.11-rc2-bk9.

Marcel
