Is there any error control in UDP protocol?
No Error control or flow control is provided by UDP. Hence UDP depends on IP and ICMP for error reporting. Used for simple request response communication when size of data is less and hence there is lesser concern about flow and error control. It is suitable protocol for multicasting as UDP supports packet switching.
Is the User Datagram Protocol ( UDP ) connectionless?
User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. Unlike TCP, it is unreliable and connectionless protocol. So, there is no need to establish connection prior to data transfer.
How to send and receive UDP packets with ESP8266?

How to create a UDP socket for a client?
The entire process can be broken down into following steps : UDP Server : Create UDP socket. Bind the socket to server address. Wait until datagram packet arrives from client. Process the datagram packet and send a reply to client.
Which is UDP protocol does not require a handshake?
Since UDP does not require a handshake, attackers can ‘flood’ a targeted server with UDP traffic without first getting that server’s permission to begin communication. A typical UDP flood attack sends a large number of UDP datagrams to random ports on its target computer.
What are the port numbers for UDP protocol?
User Datagram Protocol (UDP) is a Transport Layer protocol. UDP is a part of Internet Protocol suite, referred as UDP/IP suite. UDP port number fields are each 16 bits long, therefore range for port numbers defined from 0 to 65535; port number 0 is reserved. Port numbers help to distinguish different user requests or process.
