Re: [lwip-users] Recv UDP Problem

[Noam Weissman]

Hi,

Is this code actually a task ?

If it is please add a small delay at end of loop.

Adding a vTaskDelay call at end of loop is common practice. This is important
In order not to starve other tasks running in your system.

I do not know/think that adding the delay will solve your problem but adding 
it, is 
Important.


BR,
Noam.

Subject: [lwip-users] Recv UDP Problem

Hi,

I am able to receive UDP messages but it only works sometimes. In my example I 
sent a UDP message and I get an automatic reply. But this only works every
3-6 messages. What can be the problem. I am working on a Atsame70 with RTOS and 
Lwip 1.4

do {
                if (ERR_OK == netconn_recv(conn, &inbuf)) {
                        netbuf_free(inbuf);
                        netbuf_delete(inbuf);
                        sprintf(text, "Antwort = %i", (counter_ms+10000)); 
//1024
                        netbuf_ref(buf, text, strlen(text));
                        
                        err = netconn_sendto(conn, buf, &remote_ip_addr, 10001);
                }
} while (1);

Thanks for any ideas!
