Arduino stops working after some receivings from RF

Question

I made a sketch that receives an rgb code from a remote Arduino using nrf24l01 and while it works for the first receivings then it stops working. I placed a testing Serial.println in the loop to test if Arduino stops to work completely or it doesn't receive any other data. Finally, I understood that it continues to work but it doesnt receive more data. Bellow is my code:

#include <RF24Network.h>
#include <RF24Network_config.h>
#include <Sync.h>
#include <TimerOne.h>
#include <SPI.h>
//#include <nRF24L01.h>
#include <RF24.h>
RF24 radio(8,10);
RF24Network network(radio);
volatile int i=0; 
volatile int d=0; // Variable to use as a counter
volatile boolean zero_cross=0; // Boolean to store a "switch" to tell us if we have crossed zero
int AC_pin= 4; // Output to Opto Triac pin
int dim = 0; // Dimming level (0-128) 0 = ON, 128 = OFF
int freqStep = 65; 
struct payload_rgb
{
 unsigned int red;
 unsigned int green;
 unsigned int blue;
};
struct payload_lightuv
{
 unsigned int light;
 unsigned int uv;
};
RF24NetworkHeader header;
payload_rgb payloadrgb;
payload_lightuv payloadl;
void setup() {
 // put your setup code here, to run once:
 pinMode(AC_pin, OUTPUT);// Set AC Load pin as output
 pinMode(9, OUTPUT);// Set AC Load pin as output
 pinMode(5, OUTPUT);
 pinMode(6, OUTPUT);
 attachInterrupt(0, zero_cross_detect, RISING); // Choose the zero cross interrupt # from the table above
 Timer1.initialize(freqStep); // Initialize TimerOne library for the freq we need
 Timer1.attachInterrupt(dim_check, freqStep); 
 Serial.begin(115200);
 radio.begin();
 network.begin(90,01);
}
void loop() {
 network.update();
 while ( network.available() )
 {
 Serial.println("Rec");
 network.peek(header);
 if(header.type=='r'){
 network.read(header,&payloadrgb,sizeof(payloadrgb));
 analogWrite(6,payloadrgb.red);
 analogWrite(9,payloadrgb.green);
 analogWrite(5,payloadrgb.blue);
 }
 if(header.type=='l'){
 network.read(header,&payloadl,sizeof(payloadl));
 dim=payloadl.light;
 }
}
Serial.println("!"); //this is the test println
}
void zero_cross_detect() { 
 zero_cross = true; // set the boolean to true to tell our dimming function that a zero cross has occured
 i=0;
 digitalWrite(AC_pin, LOW); // turn off TRIAC (and AC)
} 
void dim_check() { 
 if(zero_cross == true) { 
 if(i>=dim) { 
 digitalWrite(AC_pin, HIGH); // turn on light 
 i=0; // reset time step counter 
 zero_cross = false; //reset zero cross detection
 } 
 else {
 i++; // increment time step counter 
 } 
 } 
}}

Additionally, this Arduino controls an ac dimmer. Bu I have not done it yet. How can I fix the problem without removing any feature?

• Manatok: Is it maybe running out of memory? I am not familiar with network.read but does this memory get free'd ?
• Christos Mitsis: Why network.read should use memory? The only thing that uses memory are the variables and structures. And even if it used, shouldn't the arduino stop completely?
• Manatok: I think it would have to buffer that input and if it is allocating memory each time and not cleaning up, maybe its running out. But this is just a guess. ..."If you run out of SRAM, your program may fail in unexpected ways; it will appear to upload successfully, but not run, or run strangely"...arduino.cc/en/Tutorial/Memory
