bluez-utils 2.25 (binary only, incl. Pin-Change and NAP)

• Package: master/make/pkgs/bluez-utils/

Official Linux Bluetooth protocol stack

General

It was quite an adventure to get this working, without any BlueZ documentation, but here we go :-)

PAN

Freetz PAN Server:

• Use provided default config
• Start/enable DBUS & BlueZ

(Android) PANU Client:

• Pair your device with fritz.fonwlan.box-0
• Make your device discoverable

Freetz PAN Server:

• Find your device

  hcitool scan
  

• Trust your device:

  dbus-send --system --type=method_call --dest=org.bluez --print-reply /org/bluez/$(pidof bluetoothd)/hci0/dev_YY_YY_YY_YY_YY_YY org.bluez.Device.SetProperty string:Trusted variant:boolean:true
  

• Restart BlueZ to persist data

Android PANU Client:

• Make the connection (Android: root required!):

  hcitool scan
  pand --connect xx:xx:xx:xx:xx:xx
  sleep 7
  netcfg bnep0 dhcp
  setprop net.dns1 46.182.19.48
  ifconfig rmnet0 up # trick to make apps think there is an internet connection
  

Ignore any message from the Android browser that there is no connection :-)

Automation: use Script Manager or use NC Bluetooth Tether.

Ubuntu client:

• Make the connection:

  hcitool scan
  sudo pand --connect xx:xx:xx:xx:xx:xx
  sudo ifconfig bnep0 up
  sudo dhclient bnep0
  

Tested with a Sitecom CN-517 USB dongle (pretty generic) through a USB-hub on a 7270v2 international with the (patched) btusb module and an Android device with a CyanogenMod 7 ROM and with a Ubuntu Lucid Lynx client.

lsusb:

VID=0a12
PID=0001
CLS=224
SCL=01
SPEED='full'
VER='2.0'
ISOC=1
INUM=2
ICLS1=224
ISCL1=01
ICLS2=224
ISCL2=01

Not tested with hci_usb (earlier kernels; will probably work) and bfusb (AVM - BlueFRITZ! USB).

DUN

• Select ‘Replace kernel’
• Select package pppd (Standard packages, Point-to-Point)
• I have no idea how DUN works, so maybe someone else can write the rest of the guide :-)

DBUS

See all interface methods:

dbus-send --system --dest=org.bluez --print-reply /org/bluez/$(pidof bluetoothd)/hci0 org.freedesktop.DBus.Introspectable.Introspect

See the properties of your adapter:

dbus-send --system --type=method_call --dest=org.bluez --print-reply /org/bluez/$(pidof bluetoothd)/hci0 org.bluez.Adapter.GetProperties

See the properties of your device:

dbus-send --system --type=method_call --dest=org.bluez --print-reply /org/bluez/$(pidof bluetoothd)/hci0/dev_YY_YY_YY_YY_YY_YY org.bluez.Device.GetProperties
