How to send UDP packet using javascript to local network broadcast

Question

I have build an android application that listen to the UDP broadcast url (eg: 192.168.1.255), and a website that should send a UDP packet to the broadcast url to find all devices connected to the same network at the moment, that will respond to the broadcast message by sending another broadcast to the same url. is there anyway to send UDP packet using native javascript? if not is there any alternative?

So the only solution is to use nodejs? – Converse

No, you could use any other JS runtime, but you definitely can't send arbitrary UDP packets from a browser context. – Puritanical

Answer 1

After so many research and asking, looks like there is no way to send UDP packet from native javascript due to security concerns
