Re: [Bluez-users] Setting up an hotplug connection with USB dongles

Hi Erwin,

thanks for that very useful link.

If have everything up an running, only two minor issues left on the PANU side:

1. It seems that I need to do an "hcitool scan" to make pand --search working, 
e.g.

              hcitool scan
              pand --nodetach --role PANU --search --encrypt 
--pidfile /var/run/pand.pid

It does work without hcitool scan, when I use the BT device address

              pand --connect <BT device address>

2. On the client side, I do not get dhcp to work. When I run 

               dhclient bnep0

I see on the PANU (from syslog):

Dec 19 23:07:42 topsi dhclient: DHCPDISCOVER on bnep0 to 255.255.255.255 port 
67 interval 5

There is no entry in the syslog file in the DHCP server (which is NAP). Its 
dhcpd.conf looks like this:

# Bluetooth
subnet 192.168.2.0 netmask 255.255.255.0 {
  range 192.168.2.100 192.168.2.150;
#  option broadcast-address 204.254.239.31;
  option domain-name "vix.com";
  option domain-name-servers 192.168.2.1;
  option broadcast-address 192.168.2.255;
  option routers 192.168.2.1;
}

Any ideas are welcome.

Thanks,
Rainer
