RF24Mesh network.available() always returns false

Using Arduino Networking, Protocols, and Devices
#1

For around a month now I’ve been working on a project with the RF24Mesh library between a Mega 2560 and a UNO. The pins have been the same since the beginning and I changed the code a little which seems to make network.available() always return false. I tested the setup with the example code and it worked fine. I looked through my code and nothing seems to be wrong and its not giving my any errors.

Here is my code:

Master (UNO):

#include <Arduino.h>
#include <Wire.h>
#include "Adafruit_PWMServoDriver.h"
#include "RF24Network.h"
#include "RF24.h"
#include "RF24Mesh.h"
#include <SPI.h>
#include <EEPROM.h>

RF24 radio(7,8); // CE, CS
RF24Network network(radio);
RF24Mesh mesh(radio, network);

Adafruit_PWMServoDriver pwm = Adafruit_PWMServoDriver();

const int servos[] = { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
const int extreme[] = { 150, 590 };

int pulse[11];

void setup () {
  Serial.begin(115200);
  mesh.setNodeID(0);
  mesh.begin();

  pwm.begin();
  pwm.setPWMFreq(60);
}

void loop () {
  mesh.update();
  mesh.DHCP();

  if (network.available()) {
    RF24NetworkHeader header;

    network.peek(header);

    int degree[11];

    switch (header.type) {
      case 'M':
        network.read(header, &degree, sizeof(degree));
        break;
      default:
        network.read(header, 0, 0);
        break;
    }

    for (int i = 0; i < 11; i++) {
      pulse[i] = map(degree[i], 0, 180, extreme[0], extreme[1]);

      Serial.print(F("Servo #:"));
      Serial.print(i);
      Serial.print(F(" Degree:"));
      Serial.println(degree[i]);
      
      pwm.setPWM(servos[i], 0, pulse[i]);
    }

    Serial.println("");
  }
}

Node (MEGA):

#include "RF24.h"
#include "RF24Network.h"
#include "RF24Mesh.h"
#include <SPI.h>
#include <Wire.h>
//#include <EEPROM.h>

RF24 radio(7,8); // CE, CS
RF24Network network(radio);
RF24Mesh mesh(radio, network);

#define id 1

const int controls[] = { 0, 1, 2, 3, 4, 6, 7, 8, 9, 10 };

int degree[11];

void setup () {
  Serial.begin(115200);
  
  mesh.setNodeID(id);
  mesh.begin();
}

void loop () {
  mesh.update();

  for (int i = 0; i < 11; i++) {
    degree[i] = analogRead(controls[i]);
  
    degree[i] = map(degree[i], 0, 1023, 0, 180);

        if (!mesh.write(&degree, 'M', sizeof(degree))) {
          if (!mesh.checkConnection()) mesh.renewAddress();
          else Serial.println(F("Failed to send."));
        } else {
          Serial.print(F("Sent OK. Servo #:"));
          Serial.print(i);
          Serial.print(F(" Degree:"));
          Serial.println(degree[i]);
  
          //prevDegree[i] = degree[i];
  
          delay (10);
        }
  }
}

I had it trying to send degrees of 11 pots while at the time I only had 3 plugged in. I changed it to only send data from the 3 pots and it fixed the issue

Thanks.
