Torounia
Hi,
I am trying to broadcast a UDP packet from my Raspberry Pi and receive it from another node in the same network. I am following this example Sending and Receiving UDP
I can open the port successfully but when I am trying to send the udp message to the broadcast address of the network (192.168.1.255) I am getting the {:error, :eacces} error. It works fine when I broadcast to 127.0.0.1. I know it is related to permission denied but I don’t understand which permission.
Thanks, Tas

Sending to a broadcast address will fail unless the socket uses the
SO_BROADCASToption. For:gen_udp, the option is spelled like:Torounia
Thank you. It was well hidden in the documentation.
