Geofence in Arduplane

Hello, I am facing problem in setting up the geofence:
this is the script i used

“”

from pymavlink import mavutil

import time

print(“before connecting”)
drone = mavutil.mavlink_connection(’/dev/serial/by-id/usb-3D_Robotics_PX4_FMU_v2.x_0-if00’)

drone.mav.request_data_stream_encode(drone.target_system, drone.target_component, mavutil.mavlink.MAV_DATA_STREAM_ALL, 4, 1)

drone.mav.command_long_send(1,1,207,0,1,
0,0,0,0,0,0)

drone.mav.fence_point_send(1,1,0,5,-353613970,1491728970)
drone.mav.fence_point_send(1,1,1,5,-353612170,1491729430)
drone.mav.fence_point_send(1,1,2,5,-353613280,1491732030)
drone.mav.fence_point_send(1,1,3,5,-353615720,1491726070)
drone.mav.fence_point_send(1,1,4,5,-353612170,1491729430)

drone.mav.param_set_send(1,1,“FENCE_BREACH_MAXALT”,100.0,6)
drone.mav.param_set_send(1,1,“FENCE_BREACH_MINALT”,10.0,6)
drone.mav.param_set_send(1,1,“FENCE_ACTION”,2,6)
drone.mav.param_set_send(1,1,“FENCE_CHANNEL”,7,6)
any suggestions??
