Can you share an example of what you would like to convert to what?
There are various built-in functions on the String object and the Buffer object that can be used to convert between different representations of the same data. Just needs an example from you so we know exactly what you're looking for.

Yes, I need to convert characters, for example I'm receiving 48 65 6c 6c 6f 20 77 6f 72 6c 64 21 , that it means Hello world! in ascii, this Hello world is what I want to share on screen.

And how exactly are you receiving that ascii?
Is it in a string: `"48656c6c6f20776f726c6421"`? Or some other format?

Yes, it's a payload that I receive with Lora node (the data comes from an arduino program adn in a future it will be temperatures), and the format as you say is a string.

Assuming that String is in `msg.payload`, then the following function will do it:
```auto
msg.payload = Buffer.from(msg.payload,"hex").toString()
return msg;
```

Perfect, thanks knolleary, I would try it with the mate who program the arduino in a few hours and I say something, but i seems good.
