ESP8266 Community Forum

I set a new goal. I'm trying to connect a App or Html page with the Esp8266, and making a socket connection..

I'm able to connect to the Esp using a program on the computer:
http://sockettest.sourceforge.net/

Then I tried a Cordova (Android / Ios) plugin to try to setup a socket connection. I tried:
https://github.com/Tlantic/cdv-socket-plugin

But I'm unable to connect ..

I want to configure my esp8266 as server so I setup like this in the Serial console:

*** SERIAL ***
// Connect to the network
AT+CWJAP="SSID","PASS"
AT+CIFSR
192.168.1.103

// Make it a server
AT+CIPMUX=1
AT+CIPSERVER=1,8000
*** /SERIAL

*** HTML ***
Then I have a HTML page trying to connect to the server:
if ("WebSocket" in window) {
console.log("WebSocket is supported by your Browser!");
// open the websocket
ws = new WebSocket("ws://192.168.1.103:8000");
}
*** /HTML ***

When the HTML page visit the server I get:

*** SERIAL ***
+IPD,0,431:GET / HTTP/1.1
Upgrade: websocket
Connection: Upgrade
Host: 192.168.1.103:8000
Origin: null
Pragma: no-cache
Cache-Control: no-cache
Sec-WebSocket-Key: dCJ7dO0cFCL8Bfjszc6CVg==
Sec-WebSocket-Version: 13
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits, x-webkit-deflate-frame
User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.124 Safari/537.36


OK
*** /SERIAL ***

After a while my webconsole displays:
*** HTML ***
WebSocket connection to 'ws://192.168.1.103:8000/' failed: Connection closed before receiving a handshake response
** /HTML ***

And ESP said...
*** SERIAL ***
Unlink
*** /SERIAL ***

I tried to send messages in both way. But I think there must be a handshake first.

after getting connected, there will be a connection timeout when no data is being tx'd/rx'd.
connection will automatically be terminated by esp module. you will need to reconnect.

Yeah after a while its disconnected.

But in that time it must be possible in some way to send data right? My console said its missing handshake before it can send data

You have to send the server response to the browser. In addition, you would have to implement the other features of a websocket server. So basically you probably don't want to use websockets.
