problem with /dev/rfcomm0

[Riccardo Veraldi]

Hello,
I haev Kubuntu 6.06
I configured it to connect via UMTS/GPRS using bluetooth
device.
Actually I think I did everything correctly but when I start pppd
or gnme-ppp or kppp I have the following error

Failed to open /dev/rfcomm0: Connection refused


the bluetooth device is seen correctly

I can ping the phone mac address with l2ping

I do not know what else I can do...
here I report my whole configuration.
any suggestions ?


here is /etc/bluetooth/rfcomm.conf

rfcomm0 {
  bind yes;
#       # Bluetooth address of the device
        device 00:12:37:9D:3C:53;

here is /etc/bluetoth/hcid.conf

}

# Default settings for HCI devices

        lp rswitch,hold,sniff,park;

        # Authentication and Encryption (Security Mode 3)
        #auth enable;
        #encrypt enable;
}

in the file pin I put the pin number for bluetooth communication



Here is the TIM file (provider) in /etc/ppp/peers

# These are the options to dial out to your default service provider.
# Please customize them correctly. Only the "provider" file will be
# handled by poff and pon (unless with extra command line arguments).

# You usually need this if there is no PAP authentication
noauth

# The chat script (be sure to edit that file, too!)
#connect "/usr/sbin/chat -v -f /etc/chatscripts/provider"
connect "/usr/sbin/chat -v -f /etc/chatscripts/umts_tim"

# Set up routing to go through this PPP link

# Default modem (you better replace this with /dev/ttySx!)

# Bluetooth interface in case of channel 0 usage, else substitute with
