# 7.3 Using UDP

The User Datagram Protocol (UDP) functions as a protocol within the Transport Layer. It is an integral component of the Internet Protocol suite, commonly known as the UDP/IP suite. Differing from TCP, UDP is characterized by its lack of reliability and connectionless nature. Therefore, it eliminates the requirement for prior connection establishment before initiating data transmission.

Much like establishing a connection using TCP, the process of establishing a connection using UDP entails entering the IP Address and Port number, as exemplified in the subsequent screen.

Initiating the Connect Button triggers the display of a connection progress screen, mirroring the presentation observed while connecting the drone using a TCP connection.

After a successful connection, the user will receive a voice notification confirming "Drone Connected," and the top bar of the screen will change to a vibrant green color.
