Errors in send command with python 3.3

[GoogleCodeExporter]

When I try sending data to an Xbee using the send() method there is a TypeError 
in the base.py file

the script is:
import serial
from xbee import ZigBee

serial_port = serial.Serial('/dev/cu.usbserial-A800f7SH', 9600)
xbee = ZigBee(serial_port)
xbee.send("at", frame='A', command='MY', parameter=None)
xbee.halt()
serial_port.close()

and the output is:
Traceback (most recent call last):
  File "test.py", line 6, in <module>
    xbee.send("at", frame='A', command='MY', parameter=None)
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/xbee/base.py", line 386, in send
    self._write(self._build_command(cmd, **kwargs))
  File "/Library/Frameworks/Python.framework/Versions/3.3/lib/python3.3/site-packages/xbee/base.py", line 201, in _build_command
    packet += data
TypeError: can't concat bytes to str

If I run the same script on python 2.7 it runs fine. I have tried changing the 
command to all of the optional forms in the documentation on page 6 
(xbee.at(command='MY'), etc) but none of the various options have any impact. 

I am using XBee-2.1.0 on Python 3.3 on a mac.

Thanks for your help

When you call send(), please prefix all data values with b to indicate it is a 
bytes type:

xbee.send("at", frame=b'A', command=b'MY')

This is important on Python 3.X because byte-string literals (which being with 
b) differ from normal strings.

Let me know if you still have trouble.

That fixed it. Maybe you could add that to the examples in the documentation at 
some point. Thanks for the great library.

Glad this fixed it for you. Since no library changes were required, closing as 
WontFix.
