<![CDATA[Convert RFID uid bytearray in HEX String]]>Surely I'm the one doing something wrong, but I can't find a way to convert bytearray to HEX String to be able to "readably" display the UID of a TAG on the display.

Through code I just need to add the .hex() method... but I can't find a way to do it through UI Flow 2 and it seems absurd to me!

you probably know this already - often for things where no native block is available you can use the generic Execute mpy code block as shown in the example in the Project Zone: M5Dial_RFID_as_hex_string_UIFlow2.0.7

Thanks
Felix
