  I try to stream video data to the server to control 100 ws2812 leds.
  I tried to work with 1byte for each pixel, so the current limitations do not disturb.

  But i get no stable connection. Always if i send between 25 and 60 messages i get:

  WebSocket is already in CLOSING or CLOSED state.
  

  Would be really good so solve this problem first ;) If i couldn't get a reliable connection, i can't use that websocket implementation...

  Please have a look at it. Thanks.

  Great to hear from you. Thank you for your response!

  Now it seems to work 95% :)

  Some of my tests:

  [WS] "hallo welt"
  [WS] "hallo welt 123"
  [WS] "123"
  [WS] "hallo welt 123"
  [WS] "[object Object]"
  [WS] "test"
  [WS] "{\"room\":\"room\",\"msg\":\"message\"}"
  1: [WS] "\x14"
  2: [WS] "PUM\x1F\x1D\x00\x02O^M\x02\x1E\x15MUO\x1F\n\x1C\x1E\x13\b\nO\x0Fe\x8Ah\"\xC9\x8F\x13\x00\xBB\xE0\aO\xEB\xB5JP\xA6\xE0\x05\x00\xE5\xAD\x05Q\xAE\xADR\x00\xA4\xEA\x1BQ\xA8\xE8\r\x00\xB4\x94%Nw\x83y5U\xF1\x16!\x1A\xA1Cl\x05\xEC\x16#U\xAF[#\x04\xE4[tU\xEE\x1C=\x04\xE2\x1E+U\xFE;0=\x18=\xDAF:O\xB5Ru\x1F\xE0\x1FjR\xB5"
  [WS] "{\"room\":\"room\",\"msg\":\"message\"}"
  [WS] "{\"room\":\"room\",\"msg\":\"message\"}"
  [WS] "{\"room\":\"room\",\"msg\":\"message\"}"
  

  The named lines (1,2) should be also the same message as before. My conclusion is, that i still get that "unreadable" data, if i wait a little bit.

  Start the WebSocket and send a Message -> OK
  Send more messages -> OK
  Wait a minute and send one message -> Unreadable Data
  send more messages -> Sometimes OK, timesomes unreadable
  send more messages -> everything OK

  So always if i wait a little bit it seems that the next data package can't processed successfully.

  If i wait for 5-10 Minutes and try to send a message from Chrome:

  WebSocket is already in CLOSING or CLOSED state.
  

  I would be really happy if you could check that again :)
  I will also try the capacitor for the ESP8266.

  Thank you!

  Edit: I looked at the ws.js file. Why you don't allow to send data bigger then 125 character? How can i send more than 125? I need to send more than 300 characters.

  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.
