Hi list, sorry for the noise. It works as it should and the setup I did is correct. Now it works and I do not know why it does not beforehand. Regards, Michael

I struggle with setting up an asio udp socket on Linux that is able to receive broadcasts. I managed the sending of broadcasts, but receiving seems to have a problem. I also managed sending and receiving of broadcasts with the native socket api of Linux. However, in the project we use asio to have portability across platforms and therewith we need to receive broadcast with asio too.

The question is: How should an asio udp socket be setup in order to receive broadcasts?

I did the following:

udp::socket socket(io_service); socket.open(udp::v4()); boost::asio::socket_base::broadcast option(true); socket.set_option(option); socket.bind(udp::endpoint(address_v4::any(),8888));

and then I started receive_from.

What is wrong with this? I did not receive the sent broadcast.
