Implementing UDP on Espruino, Using UDP broadcast to find server IP.

I've finally tried the master build today. Unfortunatelly it does not work when Espruino flashed directly on ESP8266 board.
Notes: I m sure using correct version, in official v1.94 the require("dgram") was not working.

I tried 3 tests and nothing worked.
*** 1. test_dgram_reuseAddr.js - error returned
Flash map 4MB:512/512, manuf 0xc8 chip 0x4014

Uncaught InternalError: Unable to create socket
at line 1 col 15
srv2.bind(port);
=undefined

*** 2. test_dgram_socket.js - nothing returned (expected msg on send and receive)
Flash map 4MB:512/512, manuf 0xc8 chip 0x4014

=undefined
server disconnected
client disconnected

          Notes: I ve tested some extra msg-logs and removed srv.close and client.close.... IMHO, still seams that network.c fails and returns into networkGetFromVarIfOnline();

*** 3. test_dgram_multi.js - nothing returned (expected msg on send and receive)
Flash map 4MB:512/512, manuf 0xc8 chip 0x4014

=undefined
server 1 disconnected
server 2 disconnected
=undefined

          Notes: also very strange that msg "server 1/2 disconnected" received but msg "client disconnected" is not received

p.s. I've tried to get connected to wifi at first, changed client.send(.... IP) to 127.0.0.1 and also to the wifi real IP after ESP is connected. Nothing changed. Would love to debug but do not know how.
