Unlike TCP, UDP lacks reliability and operates in a connectionless manner, eliminating the need for prior connection establishment before initiating data transmission. Similar to the process of establishing a connection with TCP, connecting via UDP involves entering the IP Address and Port Number, as shown in the following screen.

UDP port connect

Clicking the Connect button prompts the display of a connection progress screen, resembling the presentation observed during the drone connection using TCP. Upon successful connection, a notification will confirm " **Communication Link Established**," and the top bar of the screen will change to a vibrant green color.
