Hi Sven
I assume you mean buffer?
Yes, but you will note the 500~700 are not viewable.

It is a feature to prevent the websocket from node-red to browser being overloaded.
In situations like this, if you actually need to inspect 700 individual bytes, it is notmally recommended you write the payload to a file for closer inspection.
NOTE: the data is there (at server-side) it is just not transmitted to the debug (to keep the editor responsive)
