@m5stack I don’t think that would work, I need it to be written to the card in the raw hex value not in string, since it’s another system, that is going to read it, that will need the correct hex values and not the string converted one.

Solved it, it returns the result in Dec, and not in Hex, don't know if there is a way to convert DEC to HEX [image: 1586098055975-i2c-scanner-simple.png]
