I have no more code. I load the code I post in both arduinos. With "it" I mean the arduino Serial function.
I post all code, it is an example from xbee librarie. I just changed MY value and the lecture of a sensor for: pin5 = 135;
If I use Serial function, after send data by xbee, it shows more trash. For example, if I write: Serial.println("hello"); in the last line of loop function, I will obtain "hello" and lot of trash.
