Hello,

> I can get an RFCOMM to work, but when trying to work with hci I fail:
> 1) on /etc/init.d/bluetooth I have a line that does hciattach:

I have this card (Pretec BT2000E) with Sharp Zaurus SL-C860 with Cacko rom.
For this card exists now 3 drivers.

1. bt950_cs
This driver is probably from Marcel Holtmann and is part of BlueZ.
hciattach is not needed for this driver.
http://www.holtmann.org/linux/bluetooth/

2. bt2000e_cs
I use mometally this driver, because it works for me and it is part of Cacko
rom installation. There are some fixes with suspend/resume problems
and uart speed.
hciattach is not needed for this driver too.
http://www.iral.com/~albertr/linux/bt2000e/

3. serial_cs
This path is preferred, but I can't find right parameters for hciattach.
I've tried many combinations like this:
hciattach /dev/ttyS3 ericsson 460800
But all without success.
If somebody run card with this driver please write to the list!

If this works, you must have corretly runned hciattach...
What shows "hciconfig"?

This is my cardctl ident:
Socket 0:
  product info: "Pretec", "BT2000E", "Bluetooth PC/CF Card"
  manfid: 0x022d, 0x2000
  function: 2 (serial)

Yes card is identified as UART.

I have this config file: /etc/pcmcia/bt2000e.conf
-----------------------------------------------------------------------------
device "bt2000e_cs"
  class "bluetooth" module "bt2000e_cs"

card "AmbiCom BT2000E Bluetooth Card"
  version "AmbiCom,Inc", "BT2000E"
  bind "bt2000e_cs"

card "Pretec BT2000E Bluetooth Card"
  version "Pretec", "BT2000E"
  bind "bt2000e_cs"
------------------------------------------------------------------------------

This card works good for me.

Best regards,

Pavel Ruzicka
