Hi Folks,
since Debian Etch now also switched to GCC 4.0 as default compiler, it
is time to address all GCC 4.0 problems in the BlueZ source code. I
started two days ago with fixing most of its crazy compiler warnings.
The GCC 4.0 is really picky with the signedness and so I moved over to
explicit types like uint8_t, uint16_t and uint32_t where possible. I now
hope that I haven't introduced any signedness bugs. Please start testing
the CVS versions of libs and utils.
Regards
Marcel

last time I looked at the D-Bus 0.33 changes in the Fedora packages they
seemed to be wrong. Try it with the latest BlueZ CVS.

On a Fedora Core 4 system we have:
dbus-0.33-3
bluez-utils-2.15-7
bluez-libs-2.15-1
hcid starts up fine:
==============================================================================
hcid -n
hcid[12537]: Bluetooth HCI daemon
hcid[12537]: Starting security manager 0
==============================================================================
As soon as I try to get a Bluetooth connection, however, it dies (see
below).
What might be wrong?
This code works well on Fedora Core 3. Has something changed? We establish the
connection as follows:
int connection;
connection = socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
struct sockaddr_rc local;
local.rc_family = AF_BLUETOOTH;
local.rc_channel = 0;
bacpy(&local.rc_bdaddr, BDADDR_ANY);
bind(connection, (struct sockaddr *)&local, sizeof(local));
struct sockaddr_rc remote;
remote.rc_family = AF_BLUETOOTH;
remote.rc_channel = /* supplied channel number */;
bacpy(&remote.rc_bdaddr, &/* supplied addreess */);
connect(connection, (struct sockaddr *)&remote, sizeof(remote));
Now here's now hcid dies:
==============================================================================
hcid[12537]: link_key_request (sba=00:0A:3A:53:D7:FC, dba=00:A0:96:0A:C9:10)

12537: arguments to dbus_type_is_basic() were incorrect, assertion
"_dbus_type_is_valid (typecode) || typecode == DBUS_TYPE_INVALID" failed in

This is normally a bug in some application using the D-BUS library.

I never used sparse outside the kernel, but go ahead and send patches.

Good news. :)
I'd like to know if you're going to accept patches which fixes Linus sparse
warnings, they seems to be trivial though.
PS: I think CVS is back again, it's working here.
Thanks,

start filing bug reports at sf.net so they have to react on it and
hopefully improve their CVS service.

I've been seeing this problem on and off for a week or more.

argh, not again. This crazy error postponed the bluez-{libs|utils}-2.18
release already, because I always build the release packages from the
anonymous CVS.

no you can't, but you can use SDP to retrieve information about the
services/profiles offered by the peer device.

Bluetooth is new to me so I'll describe what I'm looking for in terms of USB.
I'm looking to determine what kind of device is connected to the other end of
the socket in the same way that I'd use the USB Vendor/Product identifiers.

this depends on the information you want. In general you need to use the
BlueZ HCI API.

Please forgive me if I'm asking a question with an obvious answer.
If, from a user-space application, I have a socket which has been created via:
socket(PF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM)
are there any special Bluetooth ioctls which can be used to, for example, query
device information? If so, where can I find and/or read about them? Is there
another interface I should be using? Thanks.
