hiI tried with secp256,secp384,secp521 the time consumption I different while using each one of them to complete the handshake.secp256 ----> 1.5 secsecp384----> 3 secsecp521----> 10 secthese are the the time consumption while using corresponding c...

if we are sending more than 1500 bytes(any value more than mentioned MTU) from the packet sender.is the nx_udp_socket_receive function will give the entire data as once or it will give fragmented data(means it will print the large chunk of data in tr...

here am using TCP echo client application code from ST.am using nx_tcp_socket_send and nx_tcp_socket_receive for TCP sending and receive operation.from server side when am sending 3000 bytes of data its splitting into 3 packets and send to client s...
