Hi! I have a problem when using xbee between my computer and my arduino.
I have a loop that looks for serial input, and if available it reads it and use the command to give a reply.
If i have this string in the bottom of the loop:
Serial.println(); everything works fine.
It looks for commands and gives reply.
BUT, if I remove the code in the bottom, so I only get a serial reply when I want to, nothing works.
Anyone here have an idea?
