I'm not sure if this is what you're looking for when you say build id for the chip, but this is what i see when I look at the back of the chip:

CE 0682
FCC ID: QOQWRAP2022-1-V2V
IC: 5132A-20221B2B
BlueGiga Technologies Inc.
20031219
WRAP THORNADO BTBM Ver.4.0

Thanks a lot!

Hi Marcel,

I just received a reply from the support group of the company that we bought the chip from. Here's some answer to the questions I ask him with regards to how to change the chip such that the HCI will be ran by host processor (which is the case we need right?).

--------------------------= -------------------------------------------------------------------

> PSKEY_HOST_INT= ERFACE how do I find out whether it is UART H4 or H5?

H4 is that sta= ndard UART protocol and that's probably what you want to use.

The &q= uot;H5" host transport protocol is properly known as the "Three
Wire Uart Transport Layer", but is commonly known as H5 within CSR= .

The value of this parameter defines the protocol. You can check/mo= dify it with PSTool.

> PSKEY_VM_DISABLE  change to true?

Yes. This disables the internal Virtual Machine inside the chip. In our cas= e it disables the iWRAP software.
With BlueZ you need to use HCI module= and not iWRAP.

> PSKEY_UART_CONFIG     = what should I set this as?

H4 requires the usage of HW flow control.

With H4 you need = to modify  PSKEY_UART_CONFIG_H4. Suggested value is 08a8 which enables= HW flow control.

> PSKEY_UART_BAUD_RATE    how do= I find out what baud rate the serial
> port is running?

What serial port you mean? The one on your= PC or something else?

> PSKEY_ONCHIP_HCI_CLIENT   = ;  set this as 0000?

Yes. That enables HCI firmware.
 <= br>> Is there any other things I need to change? Thanks a lot.

No. With those settings you should be fine.

---------------------------------------------------------------------------= ------------------

It seems to me that most of my settings are correct, besides the config i u= sed 00a8 instead of 08a8.
I will try again with these configurations:

PSKEY_HOST_INTERFACE UART H4
PSKEY_VM_DISABLE  true
 PSKEY_UART_CONFIG  08a8
PSKEY_UART_BAUD_RATE  115200
PSKEY_ONCHIP_HCI_CLIENT   0000

#hciattach -s 115200 /dev/ttyS1 csr 115200 flow

I tried using stty /dev/ttyS1 yesterday and it reads 115200 on my computer, so I suppose using that as 115200 for baud rate is correct.

Any other ideas? Thanks a lot.

Cheers,

  Arthur

if you use pstool then this is a CSR chip. What is the build id of this
chip. The correct PS key for the UART config can differ for differentfirmwares.
