[Bluez-devel] using scanner with bluez and question to csr-hci-commands

[Bluez-devel] using scanner with bluez and question to csr-hci-commands

[andreas.knuth]

Hi,

A time ago I installed csrsniff and bpasniff from cvs. I have a FTS and=
 a
BPA-Sniffer.

When I'm looking now into the cvs I can't find the code again. Why?

Now its time for me to try using this with linux too. currently I am on=
ly
tried the bpasniff. It works.  the outcome from the bpasniff looks like=

baseband packages.
Have someone written some tools for decoding the packages? Or are there=

some source /info-link available for this topic?

Second question.
The csr-ships supporting a lot of additional HCI-commands (I guess its
implementation specific ...). What I have found in your CVS is the
possibility to set the BT-Address.
Is there someone working on getting the following HCI-commands implemen=
ted
in bluez - at least in cvs for testing - too?

Display supported key length of the module
Display acl connection keylength
warm-reset Resets the module
cold-reset Resets the module
Get or set the min keylen
Get or set the max keylen
Get or set if a unitkey is used

It would be helpful for testing BT implementaions, because testing the
black boxes from our supplier is not so easy without tools.
Is this genrally possible - or are there some restrictions from CSR?



Mit freundlichen Gr=FC=DFen / kind regards

Andreas Knuth

the bpasniff is mostly complete. However the master/slave switching are
not really detected and the sniffing of encrypted links is not
supported. The csrsniff is still not finished and maybe never will be.
Ask Frontline for a Linux version of the FTE software.

It should decode at least LMP and feed the data into L2CAP. Maybe I have
to check again if I really committed the code. At the moment I am at the
LinuxTag and don't have the BPA-105 with me.

Use "hciconfig hci0 revision" as root.

> Display acl connection keylength

Use the "bccmd" tool.

> warm-reset Resets the module

Both are not implemented yet.

> Get or set the min keylen

You can use the "pskey" tool for it.

> Get or set if a unitkey is used

Don't deal with unit keys at all. It is a security risk.

I can do a lot of special things for CSR chips if you need them. However
you have to ask me nicly or convice me with money or some other gifts ;)

you need special hardware for it.

check www.fte.com, but keep in mind that csrsniff doesn't contain
working code.
