Hello,

I'm 100% I do it totally wrong but I've no new ideas anymore how to get it to work.
Thanks!

Your DataHandler function takes a char instead of a char * (and it's the same for the return value).
Also, to compare two strings stored in char arrays, you have to use strcmp. The == operator will just compare the two pointers, not the strings.
