Harald's Random Stuff

xbee-python is out in version 2.0.0 which officially supports the ZigBee (Series 2) version of the Digi XBee modules. Thus time to update my test programs to this new library.

Here the result:

import serial
from xbee import ZigBee
import time

PORT='/dev/ttyUSB0'
BAUD_RATE=9600
ser = serial.Serial(PORT, BAUD_RATE)

# ZB XBee here. If you have Series 1 XBee, try XBee(ser) instead
xbee=ZigBee(ser)

#MAC, number written on the back of the XBee module
# CO3 = my coordinator
# EP1 = my endpoint with the LED on pin 11
device={
        "CO3":'\x00\x13\xa2\x00\x40\x52\x8d\x8a',
        "EP1":'\x00\x13\xa2\x00\x40\x4a\x61\x84'
}
#64 bit address
led=False

#change remote device function
xbee.remote_at(dest_addr_long=device["EP1"],command='D2',parameter='\x02')
xbee.remote_at(dest_addr_long=device["EP1"],command='D1',parameter='\x03')
xbee.remote_at(dest_addr_long=device["EP1"],command='IR',parameter='\x04\x00')
xbee.remote_at(dest_addr_long=device["EP1"],command='IC',parameter='\x02')

while 1:
        #set led status
        led=not led
        if led:
                xbee.remote_at(dest_addr_long=device["EP1"],command='D4',parameter='\x04')
        else:
                xbee.remote_at(dest_addr_long=device["EP1"],command='D4',parameter='\x05')
        # wait 1 second
        time.sleep(1)

ser.close()

Time to learn Python. I was mostly guessing my way through the Python code of this library. Luckily it’s far easier to read and understand than some other languages. Maybe I am just not a friend of putting $ signs in front of variables.
