Simple Service Discovery Protocol

Hi,

Simple Service Discovery Protocol

Send advertise/Notify using UDP with port=1900 is failing using BSD socket.

I am sending broadcast message.

Am I missing something.

const u8* notify_data = "NOTIFY * HTTP/1.0\r\n" "Host: 239.255.255.250:1900\r\n" "Cache-Control: max-age=900\r\n" "Location: ">probuf1/index.html\r\n" "NT: upnp:rootdevice\r\n" "USN: uuid:test::upnp:rootdevice\r\n" "NTS: ssdp:alive\r\n" "Server: NBF4/1.0 UPnP/1.0 test\r\n\r\n";

int sock_;
SOCKADDR_IN addr_;

sock_ = socket (AF_INET, SOCK_DGRAM, IPPROTO_UDP);
if(sock_ == -1)
{ return;
}

addr_.sin_family = PF_INET;
addr_.sin_port = htons(port_num);
addr_.sin_addr.s_addr = INADDR_NONE;
int ret = connect (sock_, (SOCKADDR*)& addr_, sizeof(addr_));

int size = sizeof(notify_data)/sizeof(notify_data[0]);

int bytes_sent = sendto (sock_, (char *)notify_data, size, 0, (SOCKADDR*)& addr_, sizeof(addr_));

if (bytes_sent < 0) { return; // Failed here }
