Connecting a Treo650 to a Freecom DataTank 2

  1. Install bluez2-utils from Optware
  2. Install the following kernel modules: bluetooth, hci_usb, l2cap, bnep, rfcomm, hidp
  3. Create /dev/rfcomm0 as follows:
    mknod /dev/rfcomm0 c 216 0
  4. Enable routing from ppp0 to eth1 (don’t do this if you use ppp for your internet connection):

    /etc/init.d # diff -u routing.orig routing
--- routing.orig        Sat Mar 22 18:57:23 2008
+++ routing     Sat Mar 22 15:14:29 2008

  5. Edit /etc/ppp/options as follows:

    noauth
    crtscts
    lock
    local
    proxyarp
    ktune
    192.168.1.XX:192.168.1.YY
    ms-dns 192.168.1.ZZ

    (edit the last two lines to suit your network topology, the first IP address
    is your gateway device, the second IP address will be assigned to the client,
    and the third IP address is your DNS server)
  6. Add the following line to /etc/dnsmasq.conf:
    interface=eth0,ppp0
