Hi,
I'm trying out the following packages on Fedora Core 4, x86_64:
bluez-pin-0.24-2
bluez-libs-2.20-1
bluez-utils-2.20-1
dbus-0.33-3
Unfortunately hcid crashes with "buffer overflow detected" when pairing.
Is this a known problem?
Marcel, I'm happy you decided on moving to ASCII based storage. Is there
any documentation on this? Perhaps I can update the man pages if I can
get this working.
Thanks,
Fredrik

Hi Fredrik,
Use the latest CVS version. Probably this problem is related with the wrong
error handling
in the function reply_handler_function.
If you are using dbus pin helper, check if the service is
running(registered) and if the PinAgent
d-bus configuration file(bluez.conf) is in the system d-bus configuration
directory(/etc/dbus-1/system.d/) .
Regards,
Claudio

try bluez-utils-2.21 or the latest CVS. I fixed some possible buffer
overflows lately.

I did this some time ago and no, it is not documented at the moment.
Feel free to update all the manual pages. The hidd also now caches the
device information.
