connect(2): initiate connection on socket - Linux man page

The connect() system call connects the socket referred to by the file descriptor sockfd to the address specified by addr.The addrlen argument specifies the size of addr.The format of the address in addr is determined by the address space of the socket sockfd; see socket(2) for further details.. If the socket sockfd is of type SOCK_DGRAM then addr is the address to which datagrams are sent by Create UDP object - MATLAB udp - MathWorks u = udp(___,Name,Value) creates a UDP object and specifies additional options with one or more name-value pair arguments. If you specify an invalid property name or property value, the object is not created. Connect the UDP object to the host. fopen(u) Write to the host, and then read from the host. fwrite(u,65:74) A = fread(u,10) UDP — ESP8266 Arduino Core 2.7.2-26-g83fc47f6 documentation UDP¶. The purpose of example application below is to demonstrate UDP communication between ESP8266 and an external client. The application (performing the role of a server) is checking inside the loop() for an UDP packet to arrive. When a valid packet is received, an acknowledge packet is sent back to the client to the same port it has been sent out.
