Yes, I am using UDP sockets without problem.

No idea of what is your problem. What I do and works for me, in short:

----
pkg load sockets;
% UDP Socket for reception
rcv_sck=socket(AF_INET, SOCK_DGRAM, 0);
bind(rcv_sck,rcv_port);
% UDP socket for sending
send_sck=socket(AF_INET, SOCK_DGRAM, 0);
client_info = struct("addr", send_ip, "port", send_port);
connect(send_sck, client_info);
%Receive requests
[args_serial,len_s]=recv(rcv_sck,1000);
%Send results
send(send_sck,results_ser);
----

Let me know if you also want the code for the client side.
Good luck.
