Just though I would share in case anyone else needs to use igmp I can confirm it works. I have used the iot_demo as its lwip has igmp enabled. Below is the code I used on wifi connection.
Code: Select all
case STATION_GOT_IP:
wifi_get_ip_info(STATION_IF, &ipConfig);
if(ipConfig.ip.addr != 0) {
connState = WIFI_CONNECTED;
{
struct netif* netif = eagle_lwip_getif(STATION_IF);
if (NULL != netif) {
if (!(netif->flags & NETIF_FLAG_IGMP)) {
netif->flags |= NETIF_FLAG_IGMP;
igmp_start(netif);
}
ip_addr_t ipgroup;
ipaddr_aton("239.255.0.1", &ipgroup);
err_t err = igmp_joingroup(&netif->ip_addr, &ipgroup);
if(ERR_OK == err) {
dmx_sever_init();
} else {
// ERROR("igmp_joingroup result %d", err);
}
} else {
// ERROR("netif %d", netif);
}
}
return;
}
break;
