bluetooth stack test - MCAP and HDP

How can I test L2CAP, MCAP, HDP in command line/using script in ubuntu kernel 2.6.35.

When I do

$dbus --system org.bluez /org/bluez/637/hci0/dev_00_09_1F_80_XX_XX

I get follwing signal in ( dbus-monitor --system terminal):

signal sender=:1.4 -> dest=(null destination) serial=528 path=/org/bluez/637/hci0/dev_00_09_1F_80_XX_XX; interface=org.bluez.Device; member=PropertyChanged
   string "UUIDs"
   variant array [
         string "00001200-0000-1000-8000-00805f9b34fb"
         string "00001401-0000-1000-8000-00805f9b34fb"
      ]
signal sender=:1.4 -> dest=(null destination) serial=536 path=/org/bluez/637/hci0/dev_00_09_1F_80_XX_XX; interface=org.bluez.Device; member=PropertyChanged
   string "Connected"
   variant boolean false
signal sender=:1.4 -> dest=(null destination) serial=538 path=/org/bluez/637/hci0; interface=org.bluez.Adapter; member=DeviceRemoved
   object path "/org/bluez/637/hci0/dev_00_09_1F_80_XX_XX"

my assumption is MCAP is not functional. Is there any way I can test each layer of stack separately..
