[Bluez-users] hci_uart and Ambicom BT2000E

[Daniel Jimenez]

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

check it with "ps x".

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.

Marcel

Know any PCMCIA cards that DO work in Linux?

my COM One Bluetooth PCMCIA card (MC310) works.
