Following is the code I am trying. But I don't receive any output. The drone arms when connected using 'COM6' port, but not using udp. Kindly, point out the issue.
import argparse
from pymavlink import mavutil
def arm(mav_connection, arm_command):
# Wait for the first heartbeat
# This sets the system and component ID of remote system for the link
mav_connection.wait_heartbeat()
print("Heartbeat from system (system %u component %u)" %
(mav_connection.target_system, mav_connection.target_component))
mav_connection.mav.command_long_send(mav_connection.target_system, mav_connection.target_component,
mavutil.mavlink.MAV_CMD_COMPONENT_ARM_DISARM, 0, arm_command, 0, 1, 0, 0, 0, 0)
msg = mav_connection.recv_match(type='COMMAND_ACK', blocking=True)
print(msg)
# return the result of the ACK message
return msg.result
if __name__ == "__main__":
parser = argparse.ArgumentParser(description='Send arm/disarm commands using MAVLink protocol.')
parser.add_argument('-c', '--connect', help="Connection string", default='udp:localhost:14550')
parser.add_argument('-a', '--arm', type=int, choices=[0, 1], help="Arm/Disarm command", default=1)
args = parser.parse_args()
mav_connection = mavutil.mavlink_connection(args.connect)
result = arm(mav_connection, args.arm)
print(f'Result of arm/disarm command: {result}')

Your question is clearly about pymavlinkm which is for Python. This github repo is for a completely different Java library, dronefleet mavlink.
I suspect you may have better luck here: https://github.com/ArduPilot/pymavlink
