[Bluez-users] Problems with PCMCIA Bluetooth card (cbt100c)

[Bluez-users] Problems with PCMCIA Bluetooth card (cbt100c)

[Eiko Oltmanns]

Hi,

I have problems with using the conceptronic pcmcia card (cbt100c). The hotplug 
system (on a Suse 9.0 system) doesn't detect the card correctly. It detects a 
modem a loads 'serial_cs.o'. Obviously this can't work. 
So I have to setup this device manually. But I haven't found any information 
about how to do this.
Is it easyer to configure the hotplug system to setup the card correctly or to 
setup the card permanently (I don't need the hotplug function, because I 
don't want to remove the card) ?
Any information, hints or links are welcome!

Thanks in advance!

Eiko Oltmanns

this is correct if the card offers an UART. You have to use hciattach to
attach the serial device to the Bluetooth core.

the card is CSR based, but in BCSP mode or the card has no CSR chip on
it. Or it uses another init baud rate or or or ...

I did  some more research on it. The card has an CSR chip and it is in BCSP 
mode. I can execute hciattach without error messsage now:

Systemlog after inserting the card:

Then I executed 'hciattach ttyS17 bcsp' and started hcid.

Hci0 is up, but I can't use it. 'hcitool scan' doesn't find any devices. The

(This mesage appears frequently until I killl hciattach)

I had a little e-Mail conversation with Antonio Maestre, who tested the card. 
He is using it successfully with kernel 2.6.1.
I am currently running the Suse kernel 2.4.21 (Suse 9.0).
