Python parsing Bluetooth RFCOMM for 9 bytes

My data looks like this when it comes from the device (biofeedback device). There are 9 bytes in total, and I need to buffer so much, and then poll it for new/recent packets. The start packet unfortunately starts with 0x00

So far the only thing I've found that looks like what I want to do is this, but I don't know how to implement it. http://code.activestate.com/recipes/408859/


Data:  [0000002d0270025e00]
Data:  [0001004a0006026547]
Data:  [0002004b000a026343]
Data:  [00]

My code so far looks like this...

import bluetooth, sys, time, os, binascii, struct;

# Create the client socket
client_socket=BluetoothSocket( RFCOMM )

client_socket.connect(("10:00:E8:AC:4D:D0", 1))

data = ""
try:
	while True:
		try:
			data = client_socket.recv(9)
		except bluetooth.BluetoothError, b:
			print "Bluetooth Error: ", b

		if len(data) > 0:
			print "Data:  [%s]" % binascii.hexlify(data)

except KeyboardInterrupt:
	#print "Closing socket...",
	client_socket.close()
	#print "done."
