[Bluez-devel] Bonding

[Jose Vasconcellos]

Hello,

I see that the dbus message RemoveBonding clears the link key
on the bluetooth adapter but does not remove the entry from the
linkkeys file. Afterwards ListBondings still shows a bonding and
CreateBonding reports that a bonding already exists. Is this the
correct behavior?

actually it should remove the entry from the linkkeys file. Otherwise
this is a bug. Can you check the log files for errors.

Hi Marcel,

I don't see any error message in syslog or anywhere else.
The commands themselves don't seem to report anything
unusual.

I am pretty sure that it works as expected. What distro do you have
running. Maybe SELinux is restricting access to /var/lib/bluetooth/

OK, I did a little bit of digging and here's a better description:
Removing a device that has lower case hex numbers does not
remove it from the linkkeys file. You must use upper case.

[Bluez-devel] Role switching

[Olivier Le Pogam]

Hi,

I've tried two concurrent "connect" to 2 remote devices (a mobile
phone and a XP RFCOMM server) and systematically get a errno
110 on the "connect" that goes to the XP box.

I have followed Marcel advice (lm set to master) and I have recompiled
my 2.18.2002 kernel with the MH7 patch.

A "hcidump" shows that XP server is trying to switch master / slave so I
suppose that's the reason of my errno 110 (the mobile remains in slave)

Just in case ... has anybody worked a bit on the MS stack / driver and
could tell me if it's possible to disable role switch so it could remain as 
slave ?

There is a parameter under Windows CE (NoRoleSwitch) but could not
find the same for XP SP2.

Regards,
Oli

Looks like the problem is that the function textfile_del in 
common/textfile.c
calls write_key with the icase parameter set to 0. This is NOT fixed in CVS.

[Bluez-devel] Case handling (was: Bonding)

[Jose Vasconcellos]

Hi Marcel,

Looking at this code I find the logic a bit convoluted.
I don't see the point of the case checking. Wouldn't
be easier to convert any address coming from the dbus
to upper case once?

Jose

that should have been fixed. What version of bluez-utils are you
running.

check the CVS when it was fixed (if we didn't forget it). I am pretty
sure that if was fixed before 3.7, but I might be mistaken here. If it
is still broken or the patch was incomplete, please fix it and send in a
patch for it.

I added now textfile_casedel() and it makes use of it. So the CVS
version should work as expected.
