Hi,
I have running a multithreaded system. In one thread I have a such of
discovery function over UDP and programmed with the netconn API. The
other thread sent and receive data over tcp. This one is programmed with
the raw API. With the discovery thread I'm able to change the IP Address
on the fly. When I do that, the following code is running to set the new
data and restart the interface:
netconn_close(conn);
netif_set_addr(udp_netif, &newip, &netmask,
&gateway);
netif_set_up(udp_netif);
netif_set_default(udp_netif);
err = netconn_bind(conn, IP_ADDR_ANY, 5556);
If I do that twice, my tcp connection over the raw tcp is broken. All
functions of the raw tcp api are called from the tcp thread. My question:
- If I close the netconn connection, what does it happen with the tcp
connection? is going to close as well?
- how is the rigth order to shutdown both interfaces and restart it again?
Thank you in advance
Pablo
