Trying to add 2 floats an int and the char '-' to char array

Robin2:
If the purpose is just to send a sequence of characters with Serial there is no need to build them into an array. Just send them with separate Serial.print() commands. The receiving device won't know the difference.

Hai, i am trying to send it with the rf24 library to my raspberry so it can get the values separated by the - character. it just seemed like an easy way to do but clearly i was wrong -__-
