Send 4 hexadecimal values per bluetooth

Hello everybody,

I'm very new at serial programming on arduino and I like to send 4 hexadecimal values per bluetooth to my arduino uno (with a HC 06 module).
Because I'd like to use pin 2 and 3 for RX and TX I used the Software serial library. None of my scripts worked and I'm very frustrated, so could anyone help me, please?

I think your problem is on lines 17 and 27 of your sketch.

But maybe I would have a more useful comment if you had posted a copy your sketch???
