Hi,
is there anywhere a reference implementation of a TCP Client with Netconn?
I think I'm doing something wrong with the lifecycle of my "struct netconn
*conn".
In particular: If the Server closes the connection to my client, I've got an
NETCONN_EVT_ERROR through the netconn event callback.
Then in my thread I do:
netconn_close(conn);
netconn_delete(conn);
and set my statemachine state to "tryconnect" in which I start with:
if(conn)
{
netconn_close(conn);
netconn_delete(conn);
}
And create a new netconn and try to connect again:
conn = netconn_new_with_callback(NETCONN_TCP, comEvent_netconn_cb);
netconn_bind(conn, IP_ADDR_ANY, 0);
netconn_set_nonblocking(conn, 0);
LWIP_ERROR("comEvent: invalid conn", (conn != NULL), return;);
err = netconn_connect(conn, &remoteip, TCPPORT);
"conn" still exists when I enter tryconnect state. and there it tries to close
and delete it again, while netconn_delete throws an assert saying:
Assertion "netconn state error" failed at line 1119 in ../LwIP/src/api/api_msg.c
Conn-->state is here always 135 which should not exist, therefore garbage.
I'm not using MEMP_MEM_MALLOC
Should I just reuse existing netconn and create it once at startup?
Appreciate somebody's help.
Cheers
