For multicast support you need to use socket.addMembership() method (The dgram module is mostly compatible with node.js' https://nodejs.org/api/dgram.html). There are node.js ssdp implementations available to have a look at.

Here is an Espruino specific example of an mdns (multicast DNS) module I crafted.

Cool, I will try .... and I guess also socket.setMulticastInterface() can help.
But currently UDP receiving is ok already. I need a help to make correct UDP sending.

Thanks for the link https://nodejs.org/api/dgram.html, if it is fully implemented than by just using socket.send(msg, [offset, length,] port [, address] [, callback]) it should work.

Can you give me in hand in that, PLEASE...?

p.s. I did not go much in C code as I act already on .bin file with JS scripts only.

Txs, Vasily.
