how to use service to send data

edit

I have a package of a drone https://github.com/simmubhangu/pluto_drone and I have to arm the drone and make it to take off. But I cant figure out how to use rosservice to move the drone and make the drone to take off. All the services are defined it the PlutoPilot.srv file.How can I use it to send data to the drone. The drone uses wifi to connect to the laptop.

my code is like this

#!/usr/bin/env python

from plutodrone.srv import *


import rospy

class send_data():

    def __init__(self):


        rospy.init_node('drone_board_data')
        self.resp1 = rospy.Service('PlutoService', PlutoPilot, self.arm)




        resp = PlutoPilotResponse()


    def arm(self,resp):
        resp = PlutoPilotResponse()
        resp.rcRoll = 1500
        resp.rcPitch = 1500
        resp.rcYaw = 1500
        resp.rcThrottle = 1000
        resp.rcAUX4 = 1500
        return resp

if __name__ == '__main__':
    while not rospy.is_shutdown():
        test = send_data()

        rospy.spin()

This code doesn't arm the drone. How does the code interact with the drone?
