Hi @williamesp2015,

Congratulations on entering first issue on this repository :smile:

You have version 13 of framework-arduinoespressif which is the same that I have. The only difference in s/w I see now is Windows version - you have Windows 10 and I have Windows 7.

Basing on the logs and description web sockets are unable to connect at all from your PC to ESP. If they do, you would see a message on ESP like:

Open http://192.168.1.114/ to see the scope
[0] Connected from 192.168.1.101
[0] get Text: Hallo from Browser :-) Tue Jul 12 2016 19:12:26 GMT+0200 (Central European Daylight Time)
[0] get Text: ping

I guess this may be some security / blocking by a firewall or maybe some compatibility issue.

Unfortunately I do not have Windows 10 to check. I will try to upgrade my PC to Windows 10 to replicate this issue.

@williamesp2015,

I have installed Windows 10. EspScopeA0-Delta works out of box with Microsoft Edge web browser.

I was thinking about enabling debugging to have some more clues why it does not work for you. Before doing so I propose couple of simple tests:

1. Verify if your router or firewall is not filtering out websocket's traffic on port 81. You should be able to check it on http://portquiz.net/ by entering http://portquiz.net:81

   If port 81 is not filtered out, then you should see a message like:

   

2. Check if websockets are working at all with your web browser. You can do it e.g. on https://www.websocket.org/echo.html

   For me result is as follows:

3. Verify independently if websockets out of web browser do communicate with EspScopeA0-Delta by following "Creating your own test" on the above web page.

   To do so replace var wsUri = "ws://echo.websocket.org/"; with var wsUri = "ws://192.168.1.114:81"; (substitute 192.168.1.114 with IP of your ESP).

   Successful test looks as follows:

   

I wonder what will be the results for you.

Good luck :smile:

I really appreciate your help. All the tests results were OK and also I was changing host name in the websocketserver.h and returned to arduino but no success.

[williamesp2015]

GOOD NEWS. I deleted the project and imported to PlatformIO a fresh project, changed SSID and password, It is working very nice. Thank you very much

This is GREAT NEWS! I am happy it works for you. Thank you for update :smile:

Hi Krzysztof, I think for faster communication when using external ADC, binary data would be the ultimate option. Do you have any suggestion for modify to binary using webSocket.sendBIN?

Hi @williamesp2015,

Binary data transfer is on my "To Do" list planned for Golf version. I would start with MINKO GECHEV'S BLOG.
