I finally could make Nokia HDW-3 work with Fedora 8 by applying the patch listed in this mailing list.

At least everything is fine at the moment though I get the following error while playing (it still plays fine) -

[AO_ALSA] alsa-lib: pcm_bluetooth.c:417:(bluetooth_hsp_hw_params) Protocol not available (92)

Thanks

I have a Nokia HDW-3 which has been used with btsco successfully before in Fedora 4. Now, it seems I can't somehow pair it.

Here is my hcid.conf file look like:
options {
# Automatically initialize new devices
autoinit yes;

security user;

pairing multi;

# Default PIN code for incoming connections
passkey "BlueZ";
}

hcitool scan or inq can find the headset. And I also have successfully paired with my Motorola Mobile Phone (entering PIN at both Phone and Laptop side) - so I think pairing can be done with the current state of my bluez stack.

The hcidump -X -V always gives me the following results whenever I try to connect with my headset or run some command like, hcitool info <bt-addr of headset> or send direct command like CreateBonding through dbus or even when I switch-on my headset (I wonder why my dongle wants to connect with the headset since I have not saved any information of my headset in the Laptop).

These are my current bluetooth packages:

rpm -qa | grep bluez*

bluez-utils-3.20-6.fc8
gnome-bluetooth-0.10.0-1.fc8
bluez-libs-3.20-1.fc8
bluez-hcidump-1.40-1.fc8
bluez-utils-cups-3.20-6.fc8
bluez-gnome-0.14-8.fc8
bluez-gnome-analyzer-0.14-8.fc8
pybluez-0.9.2-1.fc7
bluez-utils-alsa-3.20-6.fc8
gnome-bluetooth-libs-0.10.0-1.fc8
bluez-libs-devel-3.20-1.fc8

It would be really helpful if somebody can point me somewhere why the pairing isn't happening.

Thanks
Mahtab
