Custom Widget & Mavlink

[AlexNester-QuadX]

I am creating a custom widget that will use data from mavlink.
So facing some problems:

1. How connect to QopenHD using pymavlink via udp? (Pymavlink on companion computer)

I was try : (https://mavlink.io/en/mavgen_python/)

from pymavlink import mavutil

#Start a connection listening on a UDP port_
the_connection = mavutil.mavlink_connection('udpin:localhost:14550') 

#Wait for the first heartbeat_ 
#his sets the system and component ID of remote system for the link_
the_connection.wait_heartbeat()

was trying addresses but nothing
('udpout:0.0.0.0:14550') and ('udpin:0.0.0.0:14550')
('udpout:192.168.2.1:5760') and ('udpin:192.168.2.1:5760')

and this tutorial not helped me https://www.ardusub.com/developers/pymavlink.html

2. How it possible send own messages? I noticed that all widgets use a class _fcMavlinkSystem

it will be great add to Class 2 objects for example

L_RO_PROP(int,detect_x,set_detect_x,0)
L_RO_PROP(int,detect_y,set_detect_y,0)

and then use in my widget

But hove I can send this from companion computer whith Pymavlink or dronekit?

May be better way use Define MAVLink Messages & Enums ? (https://mavlink.io/en/guide/define_xml_element.html)

please nudge me in the right direction
