[Bluez-users] AmbiCom BT2000E

[Bluez-users] AmbiCom BT2000E

[Troy A. Griffitts]

Hey guys.  Has anyone has success using and AmbiCom BT card with kernel
2.6.9?  I just upgraded to FC3 from FC1, which was a 2.4.x to 2.6.x
kernel upgrade.  I used to use the bt950 driver with this card just
fine.  Now I can't seem to get anything to work.


card "AmbiCom BT2000E Bluetooth Card"
  version "AmbiCom,Inc", "BT2000E"
  bind "serial_cs" class "bluetooth"
#  bind "btuart_cs"
#  bind "bt950_cs"

Here is the output with the serial_cs driver:

Dec  6 16:14:23 charis cardmgr[4396]: socket 0: AmbiCom BT2000E
Bluetooth Card
Dec  6 16:14:23 charis kernel: ttyS1 at I/O 0x2f8 (irq = 11) is a

ttyS1 2>&1'
Dec  6 16:14:28 charis cardmgr[4396]: + Initialization timed out.




Here is the output with the btuart_cs driver:

use only 'bind "serial_cs"' and remove the 'class "bluetooth"' for now.

When you see this then you got a new serial port ttyS1 in your system
and you must attach this device to the hci_uart driver using hcittach.

The only problem is now, that the parameters are not always clear. I
assume that the BT2000E is the Ambicom card with the Ericsson chip
inside and so you should try "hciattach ttyS1 ericsson".

If this won't work then try 2.6.10-rc3 first before anything else.

Regards

Marcel
