DBus APIs for HCI/L2CAP?

DBus APIs for HCI/L2CAP?

[Tom Allebrandi]

Hi -

Is there a DBus API for issuing HCI commands? I want to be able to issue
vendor specific commands.

Also, I want to be able set the Limited Inquiry Access Code for both
discovery and discoverability. I see the Discoverable property in
org.bluez.Adapter but I don't see any way to set the IAC.

Similarly, is there a DBus API for L2CAP? I need to be able to manually
setup channels and control the packets that I send over those channels.

I'm working with profiles that are not yet implemented in BlueZ. Also, I
need to be able to generate malformed packets for test purposes.

I'm pretty sure that I can do all of the above with BTIO or the socket
interface. I'm just trying to be a good boy and use DBus :-).

Cheers!

D-Bus is not really meant for data, it is a high level/convenient API
for applications, so if you are trying to implement a profile you
should probably stick with sockets or use BTIO as bluetoothd and obexd
does.

Ok. As I said, I'm trying to be a good boy. I've heard Marcel say words like
"use DBus not sockets" enough times that I was starting in from that end
:-). BTIO looks like a reasonable compromise.

Do you (or anyone) know if there is a Perl<->.so interface? (Perl for
Windows has an interface package that allows arbitrary functions to be
called from any old DLL. (I've never figured out XS.))

I'm not afraid of C/C++ programming, I just do a lot of my scripted type
stuff in Perl.

In my case, I'm not actually implementing whole profiles. I'm more
interested in creating feature/function centric parts of profiles similar to
the way test cases work in PTS.

That, and some downstack support API thingies since {system("hcitool");} is
just clumsy.

Thanks for the info.

Cheers!
