    I remember my high school science teacher would ask, "Any questions?" After close to a minute of silence he would add, "Do you understand enough to have any questions??" Not sure what you're even offering.

    if you don't understand then you are unlikely to need to

    turned out UDP was a poor choice, there is no guarantee UDP packets will be delivered at all or even arrive in order sent.
    i changed over to an espwebserver model and used http GET/POST requests which worked ok but on a busy network or with poor wifi reception and having multiple clients made synchronizing victron device responses with the web requests very clumsy. ESPAsyncWebServer allows for a better solution has worked nicely, so far.
    a WebSocket Server will probably be the ultimate solution when i find time to learn another trick.

    best place to start is the arduino ESPAsyncWebServer demo

    i took some ideas from this, but used littlefs rather than the deprecated spiffs


    to really get anywhere you want an understanding of c++ , html and one of the browser scripting languages like js or php
    this can answer most questions

    my current educational project is a weather station webserver;

    would love to find a socket to fit TYWE2S ESP8285 Module
    i was using the m3 but the price/availability ratio has soured
