Thank you.

   I see in your sample code that you are using recvfrom(), but with a NULL address. If you instead pass a pointer to a struct sockaddr_tipc and an address_len of sizeof(struct sockaddr_tipc), a successful recvfrom() will set it to the address of the sender, which you can turn around and pass to sendto() in order to reply. I'm using this in my own code, and so far it has worked fine.

Basically because we did not know you could do that. Will have to look into that. Is there any example code for that?
