Client can not get "Hello" message from server.
What is wrong?

server

SPI2.setup({ mosi:B15, miso:B14, sck:B13 });
var eth = require("WIZnet").connect(SPI2, B10);
eth.setIP({ ip: '192.168.1.5' }); 
console.log("IP = "+eth.getIP().ip);

var server = require("net").createServer(function(socket) {
socket.write("Hello World");
socket.on('data', function(data) {
console.log(">"+JSON.stringify(data));
socket.write("Hello");
});
});
server.listen(1234);

client

var client = require("net").connect({host: "192.168.1.5", port: 1234}, function() {
console.log('client connected');
setInterval(function() {
client.write('Get');
}, 1000);
client.on('data', function(data) {
console.log(">"+data);
});
});

Are you running these two bits of code on the same Espruino, or two different Espruinos? If it's two different Espruinos you don't seem to have set up ethernet on the client...

I guess it's possible that WIZnet can't connect to itself - the connect call is blocking on the existing WIZnet driver, so then it wouldn't be able to hand control over to the server so that it could accept the connection.

What did each device print to the console? Did they get to the point of connecting?

Client print : "Hello World" just once, server does not print anything
But if i will delete line 10 of server code, server once per second print: "Get"
