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;
