Re: [Gumstix-users] Boot to Bluetooth

[Brad M. <bmi...@xm...>]

Seth,

The only thing I had to do on the gumstix was change /etc/bluetooth/pin 
to match my access point's pin. gumstix located the network, connected, 
got an address, and I could ssh in after that. I was impressed.

My laptop side is different though... I use the debian "ipmasq" package 
so I can create a new subnet and the ipmasq package takes care of 
masquerading it. pand gets run as

  /usr/bin/pand --listen --role NAP --encrypt

My laptop's /etc/network/interfaces:

auto bnep0
# bluez
iface bnep0 inet static
   address 10.0.3.1
   netmask 255.255.255.0
   network 10.0.3.0
   broadcast 10.0.3.255
   up /usr/sbin/udhcpd /etc/udhcpd-bnep0.conf
   up /etc/init.d/bind9 restart
   up /usr/sbin/ipmasq
   down /etc/init.d/udhcpd stop

my laptop's /etc/udhcpd-bnep0.conf:

start 10.0.3.128
end 10.0.3.160
interface bnep0
option subnet 10.0.3.0
option router 10.0.3.1
option namesvr 10.0.3.1
option dns 10.0.3.1
option broadcast 10.0.3.255
max_leases 32

Note that the access point will typically try to roleswitch to become 
master. That means your gumstix can't connect to any other bluetooth 
devices while the network is up. I had some luck with having my laptop 
*not* do a roleswitch so gumstix could remain the master and connect to 
other slave devices.
