I have a hex file, the first few lines of which look as follows: :100000000C9434000C945A000C945A000C945A002E :100010000C945A000C945A000C94DA020C945A0076 :100020000C945A000C945A000C945A000C94120927 :100030000C945A000C945A000C9476080C945A00B4 :100040000C945A000C945A000C945A000C945A00C8 :100050000C945…

You need to decide if you want it as text or an array of Numbers. If the file is really long and Depending on your arduino, you might not have enough memory to save it either way

At what point in your process do you need text? As binary, it will take half the space...

Does this hex file vary? Do you need to dynamically read it Or you just need it accessible as a variable and its content is always known and the same? How big is it? Which arduino? (You can transfer numbers rather than text and the receiving arduino can re-generate the ascii HEX version)

So, convert each source byte to ASCII as you are about to write it to the output buffer.

The file remains the same and is not very big.

I don't see how that changes my answer.

If you know the file why do you need to transfer it to the second arduino? To your question, if it’s small enough to fit in flash (given it does not change), you could do a const char fileContent[] PROGMEM = R"—8<—8<—( :100000000C9434000C945A000C945A000C945A002E :100010000C945A000C945A000C94DA020…

I need to transfer it to another microcontroller and need the hex format to be saved to string.
