Hi to all, i'm looking for a way to set the source port of an UDP send to a defined number, it seems that lwIP chooses this number randomly. Is there a way to set a value in the netbuf or the netconn to a defined port number in my UDP send part? netconn_connect(tftptxcon,&modsrv_addr,ip_data_out.port); // Open connection tftpsrvbuf=netbuf_new(); // Create netbuf txdata=netbuf_ref(tftpsrvbuf,ip_data_out.buf,ip_data_out.ptr); // Assign the data netconn_send(tftptxcon,tftpsrvbuf); // Send the UDP data netconn_delete(tftptxcon); // Delete the connection netbuf_delete(tftpsrvbuf); // Delete the netbuf Thank you all for your ideas!
