I can do everything sequentially on the ESP8266. E.g. serve a page OR send endless data over HTTP. I did not find an example on how to do both "in parallel". Is there an example that does this or one I can adapt?
This use case should be similar to "upload big file" while still serving other pages.
How can I keep one HTTP connection open while still serving other HTTP requests?
How many HTTP requests can be served in parallel?
