python - thread error

[K.Clemens]

Hi,

I have following code to check the presence/absence of an LE bluetooth device.
I keep on getting following error:

Exception in thread Thread-2:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 810, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 763, in run
    self.__target(*self.__args, **self.__kwargs)
  File "check_beacon_presence.py", line 48, in SendUdp
    sock.sendto(sent_data, ("xxx.xxx.x.xxx", xxxx))
TypeError: function takes exactly 1 argument (2 given)

What I understand from searching the internet is that you can not pass a string into the thread. It has to be a "tulen"?
So what I did was: placind message between []. An other solution would be placing a "," after message without [], but also this does not work.

threadReqAway = threading.Thread(target=SendUdp, args=([message]))

## function for sending udp to loxone miniserver
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
def SendUdp(sent_data):
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    sock.sendto(sent_data, ("xxx.xxx.x.xxx", xxxx))    
## end function udp sending
message = "0"

class CheckAbsenceThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
    def run(self):

        time.sleep(ABSENCE_FREQUENCY)    
        for tag in TAG_DATA:
            elapsed_time_absence=time.time()-tag[3]
            if elapsed_time_absence>=tag[2] : # sleep execute after the first Home check.
                #logging.warning('Tag %s not seen since %i sec => update absence',tag[0],elapsed_time_absence)
                message = "AFWEZIG_"+tag[0]
                #print message
                #SendUdp(message)
                threadReqAway = threading.Thread(target=SendUdp, args=([message]))
                threadReqAway.start()
                #sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
                #sock.sendto(sent_data, ("xxx.xxx.x.xxx", xxxx))

Anyone any advice?

Some more information:

I grabbed the code from the internet.

I replaced

def request_thread(idx,cmd, name):
    try:
        url = URL_DOMOTICZ
        url=url.replace('PARAM_IDX',str(idx))
        url=url.replace('PARAM_CMD',str(cmd))
        url=url.replace('PARAM_NAME',str(name))
        result = requests.get(url,auth=(DOMOTICZ_USER, DOMOTICZ_PASS))
        logging.debug(" %s -> %s" % (threading.current_thread(), result))
    except requests.ConnectionError, e:
        logging.critical(' %s Request Failed %s - %s' % (threading.current_thread(), e, url) )

by

## function for sending udp to loxone miniserver
sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
def SendUdp(sent_data):
    sock.setsockopt(socket.SOL_SOCKET, socket.SO_BROADCAST, 1)
    sock.sendto(sent_data, ("xxx.xxx.x.xxx", xxxx))    
## end function udp sending
message = "0"

and replaced

threadReqAway = threading.Thread(target=request_thread,args=(tag[4],"AWAY",tag[0]))
                threadReqAway.start()

by

threadReqAway = threading.Thread(target=SendUdp, args=([message]))
                threadReqAway.start()

And since then I get the error....
