Details
For UDP, the sock.getdata method only extracts the data from a single UDP datagram, even if several datagrams are stored in the RX buffer. When incoming UDP datagram processing is based on the on_sock_data_arrival event, the use of the sock.nextpacket method is not required, since each invocation of the on_sock_data_arrival event handler "moves" processing to the next UDP datagram.
This method is useful when it is necessary to move to the next datagram without re-entering the on_sock_data_arrival event handler. Therefore, sock.nextpacket is only necessary when the application needs to process several incoming UDP packets at once and within a single event handler.
