GPS double output on output return value

[kujuablockchain]

Hi,

I've been on this for days. Basically i am trying to return the latitude and longitude values. The output works, the problem is that is outputs double even if i put a sleep time limit of 3 or 5 seconds. Is there a way to have the return value of print_locations only return one set of latitude and longitude? I am obviously doing something wrong.

code:

from kivy.lang import Builder
from plyer import gps

from kivy.properties import StringProperty

    self.gps = gps
    self.gps.start()
    time.sleep(5)
    self.gps.stop()

    pass

    gps_location = StringProperty()

        #self.cols = 1
        self.spacing=40
        self.padding=40

        self.add_widget(Button(text='Update and check logs', font_size=40, size_hint_y=None, height=80, on_press=gpsstart))

        self.gps = gps

        def on_location(self, **kwargs):
            self.gps_location = '\n'.join(['{}={}'.format(k, v) for k, v in kwargs.items()])

        def print_locations(**kwargs):
            location = '{lat}, {lon}'.format(**kwargs)
            #location = location.split(":")[-1]
            print(location)
            return location

        self.test = TextInput(text='aim is to print the latest location is here\nbut "print_locations" outputs double', multiline=True, size_hint_y=None, height=160, padding=30)
        self.add_widget(self.test)

        try:
            self.gps.configure(on_location=print_locations)

        except NotImplementedError:
            import traceback
            traceback.print_exc()

do not use time.sleep()
de interval of report is in minTime

gps.start(minTime, minDistance)

you can write gps.start(10000, 10)
where =
min_time, # minTime, in milliseconds
min_distance, # minDistance, in meters

now yours report lat and long every 10 seconds, you can do 1 report and then gps.stop()

sorry for my english
