hello,
I ama using lwip-1.4.1 ontop of freertos,
using a simple udp connection, I am not able to achieve the sequence
boadcast_receive_broadcast.
The first two instrunctions succeedes, however, the third, returns always
ERR_VAL (-6).
The code is nearly:
/* setup , DHCP enabled */
conn = netconn_new(NETCONN_UDP);
l_eConnErr |= netconn_bind (conn, IP_ADDR_ANY, hostPort);
l_eConnErr |= netconn_connect(conn, iIP_ADDR_ANY, remotePort);
netbuf = netbuf_new();
netconn_set_recvtimeout(conn, 1);
/* exchange data */
l_eConnErr = netconn_sendto(conn, netbuf, IP_ADDR_BROADCAST, remotePort);
// returns ERR_OK
l_eConnErr = netconn_recv(l_psConn, &l_psIONetBuf);
// returns ERR_TIMEOUT, correct in my case
l_eConnErr = netconn_sendto(conn, netbuf, IP_ADDR_BROADCAST, remotePort);
// returns ERR_VAL
