However when I do a println of the tag I get 10 characters plus another character, which is always Å
I am storing the tag values into an array of chars (char*) and when I try to output the tag in HEX the compiler says that it cannot convert char* to long int.
So, print them one-by-one, in a loop.You can't print arrays in a single print statement, except for char arrays with a NULL terminator.
I thought there were 8 binary bits in 1 byte
Not sure if this is handled internally by the Serial
