Hi, is there any chance that I can get bytes string or bytes array from hex string? I mean , get`"00001111"` or [0,0,0,0,1,1,1,1] from "08" ?

Hello, does something like println("08".toInt(radix = 16).toString(radix = 2)) suit your needs ? You can also add some padding for the leading zeroes.

I'm sorry I mean "00001000" or "[0,0,0,0,1,0,0,0]"

[Wout Werkman]

"08".toBigInteger(16).toString(2).padStart(8, '0')

Tip: these kind of questions are perfect for asking ChatGPT or friends

The BigInteger looks a bit overkill here 🙂.

[Wout Werkman]

True, but I don't know the usecase

[Klitos Kyriacou]

What is your use case? I'm asking because you ask for a "bytes string" but there's no such thing: "00001000" is a char string.
