ArtNet-Packets it's a package that contains Classes that implements low level ArtNet protocol packets

How to use:

import { Poll, PollReply } from '@rtf-dm/artnet-packets';
import { Dmx } from '@rtf-dm/artnet-packets';
import { PROTOCOL_VERSION, DIAG_PRIORITY, ARTNET_PORT } from '@rtf-dm/artnet-packets';
import { Socket } from 'dgram';

socket = dgram.createSocket({ type: 'udp4', reuseAddr: true });

const pollPacket = new Poll({
  protoVersion: PROTOCOL_VERSION,
  diagPriority: DIAG_PRIORITY.DpLow,
  flags: 0b00000110,
  targetPortAddressTop: 0,
  targetPortAddressBottom: 0,
});

const dmxPacket = new Dmx({
  protoVersion: PROTOCOL_VERSION,
  net: 0,
  length: 10,
  subNet: 0,
  sequence: 0,
  physical: 0,
  dmxData: [1, 2, 3, 4, 5, 6, 7, 8, 9, 255],
});

pollPacket.setDiagnosticsPolicy('BROADCAST');

await socket.send(pollPacket.encode(), ARTNET_PORT, '0.0.0.0'); // sending a broadcast poll packet to trigger ArtNet node reply with poll reply

socket.on('message', (data: Buffer, remoteInfo: RemoteInfo) => {
  if (PollReply.is(data)) {
    const pollReply = PollReply.create(data); // new instance of poll reply
    const pollReplyPayload = new PollReply().decode(data); // poll reply payload

    console.log(`remote node response with PollReply`);
    console.dir(remoteInfo);
    console.dir(pollReply);
    console.dir(pollReplyPayload);

    const dmxUdpPacket: Buffer = dmxPacket.encode();

    socket.send(dmxUdpPacket, ARTNET_PORT, remoteInfo.address);
  }
});
