yeah you have reason, I'd like to do a cast ... so the cast correct is that
text_arrived[i] = (char)buf[i];
thanks for the explanation, so I want id like to do this :
I've a trasmitter and the receiver, from the trasmitter I send out something for example the char '2' , on the receiver Id like to check if '2' is for the receiver or not ... I'm trying to find out an easy way for to do that ... you can suggest something ?
So, im spending a lot of hours on that ... but I didn't find an effeciency solution ...
Thanks Andrea ...
