Flock of Birds

[Atul Thakur]

Hi,
I am new to this community. I am using Flock of Birds (FOB=1). Following is the simple scripts I am trying

PHP Code:

import viz
viz.go()
BAUD_FOB = 38400
PORT_FOB = 1

sensor = viz.add('flockofbirds.dls')

def mytimer( num ):
    print sensor.getPosition()

viz.callback( viz.TIMER_EVENT, mytimer )
viz.starttimer( 0, 0.5, viz.FOREVER ) 


The output expected is the dynamic positions of Wanda as I move it. But I am getting same coordinates repeated.
However, if I run the script again, I get the new coordinates <which shows that hardware works fine>, repeating again.
Not sure what is the mistake in the code, I am making.
Someone, kindly help.
