[Bluez-users] UART bluetooth chip problem

[Bluez-users] UART bluetooth chip problem

[-- Attachment #1: Type: text/plain, Size: 742 bytes --]

Hi, I am currently using a bluetooth chip by bluegiga (www.bluegiga.com),
called WRAP THOR 2022-1-B2B.
I set the configurations on the chip so that it is running at 115200 baud
rate. After, I tried doing the following:

# hcid
# hciattach -s 115200 /dev/ttyS1 any 115200 flow
# hciconfig
hci0:   Type: UART
        BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
        DOWN INIT RUNNING
        RX bytes:0 acl:0 sco:0 events:0 errors:0
        TX bytes:4 acl:0 sco:0 commands:1 errors:0
# hciconfig hci0 up
Can't init device hci0: Connection timed out (145)

I checked and error code 145 indeed means Connection timed out on my header
files (errno.h).
What might be wrong?

Thanks a lot.

Cheers,

  Arthur

first, you should ask you module manufacturer what chip they are using
and then what transport they use.

Hi Marcel, thanks for your reply.

Since I can change the setting on the bluetooth chip, I am currently using
UART H4 and baudrate 115200. As for what chip they are using, I suppose they
manufacture their own bluetooh chip?

Thanks,

  Arthur

no they don't. With what tool do you change the settings?

Hi, I used pstool, which is a tool bluegiga made to change settings of the
bluetooth chip via SPI interface. To be more specific, settings I changed on
the bluetooth chip includes:

PSKEY_HOST_INTERFACE UART H4
PSKEY_VM_DISABLE  true
PSKEY_UART_CONFIG  00a8
PSKEY_UART_BAUD_RATE  115200
PSKEY_ONCHIP_HCI_CLIENT   0000

I tried noflow as well, but doesn't seem to help.

When you say what chip the module manufacturer is using, what do you mean
specifically?
Do you mean the "type" option in hciattach (ericsson, digi, csr... etc) ?

Thanks a lot for the help.

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 different
firmwares.

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_INTERFACE how do I find out whether it is UART H4 or H5?

H4 is that standard UART protocol and that's probably what you want to use.

The "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/modify it
with PSTool.

> PSKEY_VM_DISABLE  change to true?

Yes. This disables the internal Virtual Machine inside the chip. In our case
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.

> 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
used 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

Ops, one more thing,
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!

I just tried both UART H4 (with settings I mentioned before, plus I tried
both flow and noflow)
and also UART H5 (same settings, besides the config option I used 1806,
which is their default one. tried flow and no flow as well).

When I select csr as the type, hciattach gives me initialization time out
for all of the above I tried.
when I select any as the type, hciattach succeed, however I get connection
time out error when I try hciconfig hci0 up.

Thanks,

  Arthur

Hi Arthur,

the build id is the firmware identifier. It is a uint16 and you also
find it as HCI Revision or LMP Subversion in case of a CSR chip.

I don't know anything about their module. I don't know what firmware
version they use and what kind of special settings they might have.
However a CSR chip in general is fully supported and with bccmd from CVS
you even have a powerful tool for its configuration, but you need to
know what you are doing.

The comments you got are almost one-to-one extracts from the pskeys.txt
file that comes with every CSR firmware. If they don't do better then
send these modules back and order other CSR based modules from a company
that knows what their customers are asking them.

Regards

Marcel

Hi Marcel,

I checked the firmware version and this is what it says:
"The chip reports version 1503 (0x05df):
bc02x_8unified_fl_bt1.2_18_200407161536_encr56 2004-07-16"

What should I ask the support group then? It seems like they verified that
the settings I used on the chip is sufficient to modify the chip so that it
fits the requirements of hciattach (baud_rate and setting it to use external
HCI provided by hcid).

What other things would you suggest me to try? Hopefully you can help me to
get this to work. Thanks a lot!

Cheers,

  Arthur

I am not 100% sure, but I think the PS key for UART configuration and
baud rate settings were with HCI 18.x firmware. Meaning that there
exists per transport PS keys. However I might be also wrong here. Tell
them to send you the pskeys.txt file.

Marcel

Hi Marcel,

After the weekend I finally get a reply to the email that I sent asking for
pskeys.txt.

"Unfortunately not. But I have pskeys.html instead. :) I hope that will do.
Please do not pay attention to the default values mentioned in the file,
some
of them may vary in out modules."

I'm not sure whether I can attach files to this mailing list. So I send the
pskeys.html file to your personal email (marcel@holtmann.org) seperately,
hope that's fine. Once again, thanks a lot for your help.

Cheers,

  Arthur

the pskeys.txt and pskeys.html contain the same information. I prefer a
text file, instead of a HTML file. Everybody who uses a decent OS knows
the reason for that ;)

However I think that you need to configure PSKEY_UART_CONFIG_H4 if you
wanna use H4 as transport. The problem actually are the values that
differ from the default. The one thing that the bccmd is missing is
support for SPI as transport otherwise it would read the non-default
values and we would see what they did with their modules. The PSTool can
actually do the same, but don't ask me how. I never did that before.

Maybe using BCSP as transport will work much better, because they didn't
fucked up its configuration.

Marcel

Hi Marcel,

I tried the using the BCSP as the protocol and set the
PSKEY_UART_CONFIG_BCSP value as 0806, however, when I tried to attach the
chip again, using:

hciattach -s 115200 /dev/ttyS1 bcsp 115200 noflow

I get BCSP initialization error. I tried using flow too but that doesn't
help. Finally, I used "any" for the type again and the hciattach worked.
However when i run hciconfig hci0 up i get another connection timed out. :(

I have absolutely no idea what might be wrong... :( Hope you have some
clues.

Thanks,

  Arthur

I have no clue, because I don't know the settings of this module. The
any identifier is too stupid to detect a working UART, but the csr and
bcsp identifiers will do this. Maybe your UART is broken. Can you use
PSTool over the UART?

Marcel

Hi Marcel, sorry for the late reply. I was busy working on something else
for the past week.

I have tried using PStool over UART. I have a seperate mini circuit board
that connects to the chip via UART and I connect to that circuit board via
parallel port. However, I haven't tried the UART on the system that I'm
trying to connect to the chip to. I did some investigation by adding printf
statements in the hciattach source code and recompiled it. It seems like the
initialization stalls when it is trying to read from the UART fd.

I used csr as the type. It hangs in the read_hci_event function within the
csr function. It seems like UART is working as I can write to the file
descriptor opened, but it is not getting any response back from the chip
after the (GET_BUILD_ID) command is written to the UART.

Would there be some different command I need to send? Or would the chip is
not a csr chip? Or being able to write without failing still doesn't show
that the UART is working on the system?

Thanks a lot,

  Arthur

I think your UART is not configured correctly. Ask your Bluetooth module
manufacturer to help you. Or make it work with Windows and PSTool over
the UART and we can work from there on.

Thanks Marcel, I'll try to figure out whether the UART is messed up
meanwhile. Will let you know the result ASAP.

You might try "noflow" instead of "flow" to see if there is some problem
with the UART flow control setup/signals.

Hi Marcel, thanks for your reply.

Since I can change the setting on the bluetooth chip, I am currently
using UART H4 and baudrate 115200. As for what chip they are using, I
suppose they manufacture their own bluetooh chip? 

Thanks,

  Arthur

	first, you should ask you module manufacturer what chip they are
using 
	and then what transport they use.
