Hello, I am new to using Mayflies and XBee modules, so I’m hoping I can get some help here since the modules I’m planning on using are the 900 MHz XBee Pro S3B. Programming the modules correctly in the XTCU is something I don’t entirely grasp, but for the moment I will focus on programming the Mayfly.

Right now I am just trying to get two Mayflies to send/receive temperature measurements from the Mayfly’s built-in temperature sensor. This first bit of code is for the Mayfly making the measurement and sending the data. The green LED (pin 8) is just so I can easily tell that the Mayfly is running the loop when I have it plugged into a wall.

#include <Wire.h>
#include "Sodaq_DS3231.h"

void setup() 
{
  Serial1.begin(9600);
  Wire.begin();
  rtc.begin();  

}

void loop() 
{
  digitalWrite(8, HIGH);
  rtc.convertTemperature();
  
  Serial1.print(rtc.getTemperature());
  Serial1.println(" deg C");
  
  delay(1000);
  digitalWrite(8, LOW);

  delay(1000);
}

#include <Wire.h>

#include "Sodaq_DS3231.h"

void setup()

{

Serial1.begin(9600);

Wire.begin();

rtc.begin();

}

void loop()

{

digitalWrite(8, HIGH);

rtc.convertTemperature();

Serial1.print(rtc.getTemperature());

Serial1.println(" deg C");

delay(1000);

digitalWrite(8, LOW);

delay(1000);

}

This next bit of code is for the Mayfly receiving the data and then printing it to the serial monitor so that I can verify that it is indeed receiving the data.

#include <Wire.h>

void setup() 
{
  Serial.begin(57600);
  Serial1.begin(9600);
}

void loop() 
{
  Serial.println(Serial1.read());
  delay(250);
}

#include <Wire.h>

void setup()

{

Serial.begin(57600);

Serial1.begin(9600);

}

void loop()

{

Serial.println(Serial1.read());

delay(250);

}

Right now my serial monitor just prints out a bunch of -1 values. Any help is appreciated. Thanks!
