i also came across that the callback functions have to be declared at the top of the code... this is not the case in the OSX version.

i will update the examples.

I tried the new version.
Compiling works fine.
Now I need tot test if it will work

Thanks for the efford

okay.

just added the forward declarations to the examples.

I tried to connect to my RPI as a server.

The ESP is saying it does have a connection and is sending mesaages.

I doe receive an error on the raspberry:

Code: Select all[W 151109 23:19:58 iostream:425] Read error on 8: [Errno 104] Connection reset by peer
[W 151109 23:19:58 iostream:359] error on read
    Traceback (most recent call last):
      File "/usr/lib/python2.7/dist-packages/tornado/iostream.py", line 354, in _handle_read
        if self._read_to_buffer() == 0:
      File "/usr/lib/python2.7/dist-packages/tornado/iostream.py", line 421, in _read_to_buffer
        chunk = self._read_from_socket()

        chunk = self.socket.recv(self.read_chunk_size)
    error: [Errno 104] Connection reset by peer


I did write some code in Pytho for the server at the RPI.
The code is:

Code: Select all#!/usr/bin/env python
import tornado.httpserver
import tornado.ioloop
import tornado.options
import tornado.web
import tornado.websocket

TestVar = ""
from tornado.options import define, options
define("port", default=222, help="run on the given port", type=int)

class WebSocketHandler(tornado.websocket.WebSocketHandler):
    def open(self):
        print 'new connection from : %s' % self.request.remote_ip
        self.write_message("connected")

    def on_message(self, message):
        print 'message received : %s from ip %s' % (message, self.request.remote_ip)
        TestVar = self.request.remote_ip + ' ' + message
        self.write_message('message received : %s' % message)
        print TestVar

    def on_close(self):
        print 'connection closed from : %s' % self.request.remote_ip

if __name__ == "__main__":
    tornado.options.parse_command_line()
    app = tornado.web.Application(
        handlers=[
            (r"/", WebSocketHandler)
        ]
    )
    httpServer = tornado.httpserver.HTTPServer(app)
    httpServer.listen(options.port)
    print "Listening on port:", options.port
    tornado.ioloop.IOLoop.instance().start()


Do you see something I'm doing wrong?

- Mon Nov 09, 2015 6:20 pm #33592 seems you are creating a websocket on the server.

esp-socket is not handling websockets.

can you try with a raw tcp socket instead?
