Arduino Uno's with Xbee's - getting random numbers returned?

Hi all, I’ve got two Arduino Uno’s connected wirelessly with two XBee modules and they seem to be connected correctly but when I look at the serial on Arduino, I get a few random numbers creeping in which is confusing, when I test the sending code to A Xbee connected to an explorer, I get the correct inputs.

51,48, 13 ,10, 51, 48, 13, 10, 51, 48, 13, 10

The problem is the 13’s and the 10’s popping out of no where. I’m using a flex sensor to get a reading and then control a servo on another side.

Code for sending:

int const Finger1 = A0; //the pin the test flex is connected to
 
void setup(){
Serial.begin(9600); //open up the serial port on 9600
}
 
void loop(){
 
int FingerV1 = analogRead(Finger1); //read in the values of the flex sensor

//if (FingerV1 > 200) FingerV1 = 200;
//else if (FingerV1 < 100) FingerV1 = 100;

byte servoVal1 = map(FingerV1,255, 75, 0, 255); //map our values to give a good solid range
 
 Serial.println(servoVal1); //print our values on the serial
 
 delay(100);
}

Code for receiving:

#include <Servo.h>

Servo myservo1;  // create servo object to control a servo


void setup()
{
   Serial.begin(9600);
   
   myservo1.attach(9);  // attaches the servo on pin 9 to the servo object

}

void loop()
{
   if(Serial.available() >=1)
   {
    byte servoAng1 = Serial.read();


    // Send the servo to the position read... <-- you get to make this happen
    Serial.println(servoAng1);
    myservo1.write(servoAng1);
   }
}

The problem is the 13's and the 10's popping out of no where.

You mean the carriage return and line feeds?

Don't use println() if you don't want them. But, if you don't, how will you know when one value ends and another begins?
