Hi.

I tried that code, but i just recieve unreadyable data at the server.

ws.on('message',function(msg) { print("[WS] "+JSON.stringify(msg)); });

The result in the web-ide is like that:

[WS] "\xC7\xD3\x00\x00\xC7\xD3\x00\x00\xC7\xD3"
[WS] ""
[WS] "\x1A\t\x00\x00\x1A\t\x00\x00\x1A\t"
[WS] ""
[WS] ""
[WS] "/<\x00\x00/<\x00\x00/<"
[WS] "bl\x1C\x00bl\x1C\x00bl"
[WS] "R\x9E\xEF\x00R\x9E\xEF\x00R\x9E"
[WS] "<C\x00\x00<C\x00\x00<C"
[WS] "\xE9\xBC\x00\x00\xE9\xBC\x00\x00\xE9\xBC"

That should be always the same message...

ws.send("hallo welt");

What is wrong with the code? I run it with the pico VERSION 1v85 in combination with the esp8266.
I hope someone can help me with that.

In addition the connection interrupt all the time. Is there an easy solution for a stable connection? I want to send a lot of data from client to the server.

FullCode:

Serial2.setup(9600, {    rx: A3,    tx: A2}); 
var wifi = require("ESP8266WiFi").connect(Serial2, function(err) {
    if (err) throw err;
    wifi.reset(function(err) {
        if (err) throw err;
        console.log("Connecting to WiFi");
        wifi.connect("SSID", "12345", function(err) {
            if (err) throw err;

            var server = require('ws').createServer(onPageRequest);
            server.listen(8000);
            server.on("websocket", function(ws) {
                ws.on('message',function(msg) {
                  print("[WS] "+JSON.stringify(msg));
                });
                ws.on('open', function() {
                  ws.send("Connected to server!");
                });
                ws.send("Hello from Espruino!");
            });
        });
    });
});
var page = '<html><head><meta charset="utf-8"><title>WebSocket Client Test...</title></head><body><script>var ws;setTimeout(function(){';
page += 'ws = new WebSocket("ws://" + location.host + "/my_websocket", "text");';
page += 'ws.onmessage = function (event) { console.log("MSG: "+event.data); };';
page += 'setTimeout(function() { ws.send("Hello to Espruino!"); }, 1000);';
page += '},1000);</script></body></html>';
page += '</script></body></html>';
function onPageRequest(req, res) {
    res.writeHead(200, {        'Content-Type': 'text/html'    });
    res.end(page);
}

In Browserconsole (Chrome) i entered "ws.send(hallo welt)".

Thanks.
