[Bluez-users] Ambicom BT2000E card, can't get hciattach to work

[Bluez-users] Ambicom BT2000E card, can't get hciattach to work

[Eran]

Hello,
I recently purchased at BT2000E card and tried making it work with bluez.
I have installed bluetooth drivers and according to the instructions 
from this page 
(http://www.zaurususergroup.com/modules.php?op=modload&name=phpWiki&file=index&pagename=Bluetooth) 
and I had to mess around a bit with the /etc/init.d/bluetooth file in 
order to make things work.
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:
root@thumper:/etc/pcmcia# /usr/sbin/hciattach /dev/ttyS3 bcsp 57600
Can't get port settings: Input/output error
Can't initialize device: Input/output error

2) hcitool scan and cc <phone> works, but hci lq fails:
root@thumper:/etc/pcmcia# hcitool lq 00:80:37:D6:93:D5
HCI get_link_quality cmd failed (0x01)

This command worked for me with another bluetooth card (those cheap 
mavin cards) and I assume it has something to do with the hciattach failing.

Extra info:
I'm on sharp zarusu SL-5500 with OZ 3.3.5 and kernel  
2.4.18-rmk7-pxa3-embedix (default OZ).
cardctl ident output:
root@thumper:/etc/pcmcia# cardctl ident
Socket 0:
  product info: "AmbiCom,Inc", "BT2000E", "Bluetooth PC/CF Card"
  manfid: 0x022d, 0x2000
  function: 2 (serial)
dmesg of bluez drivers doesn't show anything special, And before I 
installed bluetooth drivers the card showed as serial device on /dev/ttyS3.

Thank you all and keep up the good work,
ERan

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

Re: [Bluez-users] Ambicom BT2000E card, can't get hciattach to work

Sorry I forgot to mention it - but hciconfig shows a fully 'up and 
running' interface. I use the bt950_cs driver.
I further checked and most hcitool commands work except the link quality.
I Have tried removing the bluetooth.conf from my pcmcia/ directory and 
use hciattach with /dev/ttyS03, but no success here as well (could not 
find correct parameters). Why is it the preferred way?

I don't try link quality. It's possible, that this function doesn't work with 
this driver or your BT devices doesn't have established connection.

Because there are more BT cards with BT950 uart and ericsson chipset which
supposedly works with serial_cs driver and hciattach.
It's better to have for all these cards only one universal driver.

It's possible, that BT2000E requires some special initialization which 
hciattach doesn't know, but I'am not expert.

Pavel Ruzicka
