Re: lwIP netconn: netif_addr, what is the correct variable

Thanks! Sadly I could not get it to work. Your example uses BSD sockets which I would like to avoid. It would be really great if someone could help me to get it work. Please see my example. Thank you very much! static void udp_send_multicast(void *pvParameters) { char tag[] = "udp_multicast_send_tas...

lwIP netconn: netif_addr, what is the correct variable

Hello, I would like to use the netconn api in lwIP to use multicast. There is the function "netconn_join_leave_group" which has the parameter "netif_addr" which is described as "the IP address of the network interface on which to send the imgp message".

Re: ESP32 TFT display library

Thank...
