i am trying to receive dns sd broadcast messages on my esp8266 using the following code:

var wifi = require("Wifi");

wifi.connect("awifi", {password:"apwd"}, function(err){
    console.log(err);
    const dgram = require('dgram');
    const srv = dgram.createSocket('udp4');
    srv.addMembership('224.0.0.251');
    srv.bind(5353, '0.0.0.0', bound => {
        console.log('bound');
        function onDatagram(msg, info) {
            console.log('memory');
        }

        bound.on('message', onDatagram);
        bound.on('close', function(err) {
          console.log('s:close', err);
        });
    });
});

wifi.stopAP();

unfortunately i get only the following warning:

WARNING: Recv 869 too long (UDP)!

any ideas how to overcome this? I assume its a problem about max datagram message size?
