Hi all,  
I am trying to put XBEE 3.0 module in sleep mode through Python app. However I am getting EALREADY error. I configured XBEE to be end device using XCTU. How can I over come this error and put XBEE module in sleep mode? Thank you for your time.

Python sleep() will pause for an hour, day or whatever if given the proper value. It does not allow other processes take place (in same script) however. A better way is to use an event which will create an event on timeout.

Have a look at threading.Timer. It runs your function in a new thread without using sleep().

from threading import Timer

def hello():  
print “hello, world”

t = Timer(30.0, hello)  
t.start() # after 30 seconds, “hello, world” will be printed

The second method to delay would be using the implicit wait method:

driver.implicitly\_wait(5)

The third method is more useful when you have to wait until a particular action is completed or until an element is found:

self.wait.until(EC.presence\_of\_element\_located((By.ID, ‘UserName’))
