Hi all,

In a previous thread Marcell recommended I use serial_cs and hci_uart for my Ambicom PCMCIA bluetooth adaptor.

I've got serial_cs working, and it's created device /dev/ttyS1.

I did a hciattach /dev/ttyS1 ericsson and that returned no errors/notices.

hciconfig hci0 up hangs and does nothing. I can control+c out of it.

...

I do notice this in /var/log/messages:

hcid[6522]: HCI dev 0 registered
hcid[6437]: HCI dev 0 registered
hcid[6295]: HCI dev 0 registered
hcid[7097]: Can't init device hci0. Connection timed out(110) hcid[7098]: Can't init device hci0. Connection timed out(110) hcid[7099]: Can't init device hci0. Connection timed out(110)

...

I am on kernel 2.6.5.

Tia,

you should check how many hcid you have running. There must only be one.

The other problem is that not every serial based PCMCIA card works right now with the 2.6 kernel. Some do and some don't and actually this is a problem in the serial subsystem, but I don't know where.

Regards

Marcel

Do you mean by doing hciconfig -a? I only see one interface that way.

check it with "ps x".

Interesting and disappointing. I bought this card because I thought it worked based on the hardware list :(. What can I do to find out if it's the card?

I tested a Pretec card with an Ericsson chip on it and the card don't works either, but sometimes I get some bytes. I don't have enough time to dig deeper into it, but it must be possible to use these cards with serial_cs and hci_uart.

Regards

Marcel

Know any PCMCIA cards that DO work in Linux?

Thanks,

my COM One Bluetooth PCMCIA card (MC310) works.
