Question regarding to implement a UDP client using net_app APIs


Robert Chou
 

Hi,

 

I’m comparing implement a UDP client by using net_app and net_context APIs.

 

When using net_context APIs, I’m able to send and receive data from any peer (register receive callback through net_context_recv()).

Since UDP is connectionless, it’s an expected behavior as long as I don’t call net_context_connect().

 

However, if I use net_app APIs to implement a UDP client, it seems that I’m unable to do the same thing.

I’m able to send out the data to the requested peer by calling net_app_send_pkt().

However, I’m unable to receive the data from the peer by registering the receive callback through net_app_set_cb() and without calling net_app_connect().

 

Is this an intended behavior of net_app API?
