Typically, when connecting to the esp8266 using a browser, you can see on the serial "winsock connected... ip address" and then when you disconnect the serial says winsock disconnected. Are there any gui buffer limitations or anything else that would prevent this winsock from operating, are there things to look out for that would prevent the connection from working?

typically the only time you run in to memory problems is when a web page is being loaded initially. Once the web socket connection is established it will send the data to the browser dynamically while keeping a cache on the device if new client connects or the page is refreshed i the browser.

Also note that only 4 simotanouse connection can happen with the esp any any one time.

Thanks for that info Mike. The attached program works perfectly in all aspects. I am trying to figure out why adding to the GUI the remmed out textboxes in the gui sub kills the winsock connect, winsock disconnect on a 4mbit esp running A65.

The only difference between a perfectly working setup where the winsock works great on several different browsers, on all different machines, including iphone, mac, etc. (only one connection to the esp though), is the addition of 6 textboxes. Does this sound like a winsock problem, or a gui buffer problem or something else?

I have tried many different ways of doing the gui, with different "wait" setups and "returngui" setups and they all do the same thing when I add the 6 additional textboxes, winsock connect and disconnect don't work and the browser window is just blank, but program is running.

Any help or ideas would be great. Thanks!
