BlynkTimer crashes whole program

Hello, everybody!
Hardware: SIM800C+ArduinoUNO+Android.
Maybe, someone knows, how to solve this problem: When I add BlynkTimer in my program - blynk begins to disconnect. Without BlynkTimer everything works fine.

Here is the program:

#define BLYNK_PRINT Serial
#define TINY_GSM_MODEM_SIM800
#define BLYNK_HEARTBEAT 60
#include <RF24Network.h>
#include <RF24.h>
#include <SPI.h>
#include <TinyGsmClient.h>
#include <BlynkSimpleSIM800.h>
#include <SoftwareSerial.h>
#define pinBOOT 9
//BlynkTimer timer;
SoftwareSerial SerialAT(7,8); // RX, TX (17,16)
TinyGsm modem(SerialAT);
char auth[] = "-M86LN2UMefPv2T";
char apn[]  = "internet.mts.ru";
char user[] = "";
char pass[] = "";
RF24 radio(4,5);
// Network uses that radio
float data[2];
float data1[2];
float data2[2];
float data3[2];
int state = 0;
WidgetLED ledTest(V5);
WidgetLED ledLight(V7);

BLYNK_WRITE(V4){  /////////TEST
  if (param.asInt())
  {
    ledTest.on();
  }
  else
  {
    ledTest.off();
  }
}
RF24Network network(radio);
void sendDirectiveOff(){
   RF24NetworkHeader header(03);    //кому отправляем
   state = 0;
   Serial.println("sending state...");
   Serial.println(state);
   network.write(header,&state,sizeof(state));
}
void sendDirectiveOn() {                
 RF24NetworkHeader header(03);    //кому отправляем
 int state = 1;
 Serial.println("sending state...");
 Serial.println(1);
 network.write(header,&state,sizeof(state)); 
}
BLYNK_WRITE(V6){  //////LIGHT
  if (param.asInt())
  {
    sendDirectiveOn();
    Serial.println("Light on!");
  }
  else
  {
    sendDirectiveOff();
    Serial.println("Light off!");
   
  }
}
void printValuesToBlynk(){
  Blynk.virtualWrite(V0, data1[0]);
  Blynk.virtualWrite(V1, data1[1]);
  Blynk.virtualWrite(V2, data2[0]);
  Blynk.virtualWrite(V3, data2[1]);
  if(data3[0] == 1){ledLight.on(); } else {ledLight.off();}
  Blynk.virtualWrite(V8, data3[1]);
}
//int timer_printBlynk = timer.setInterval(5000L, printValuesToBlynk); 
void setup() {
  Serial.begin(9600);
  delay(10);
  // Set GSM module baud rate
  SerialAT.begin(9600);
  delay(3000);
  digitalWrite(pinBOOT, HIGH);            
  delay(1000);
  digitalWrite(pinBOOT, LOW);
  Serial.println("Initializing modem...");
  modem.restart();
  Blynk.begin(auth, modem, apn, user, pass); 
  while (Blynk.connect() == false) { }
  SPI.begin();
  radio.begin();
  network.begin(120, 00);
 // timer.enable(timer_printBlynk);
  //timer.setInterval(5000,printValuesToBlynk);
}

void loop() {
  // put your main code here, to run repeatedly:
  Blynk.run();
 // timer.run();
  network.update();
      while ( network.available()){
      RF24NetworkHeader header;                            
      network.read(header,&data,sizeof(data));                  // читаем данные 
      Serial.println("From: ");
      Serial.println(header.from_node);
      if(header.from_node == 1){
       data1[0] = data[0];
       data1[1] = data[1];
      } else if (header.from_node == 2){
       data2[0] = data[0];
       data2[1] = data[1];
      }  else if (header.from_node == 3) {
       data3[0] = data[0];
       data3[1] = data[1];
      }
    }
}

Clean your loop.

Ok, only with Blynk.run() in loop and with commented timer - works.
With Blynk.run() in loop and with uncommented timer - disconnects. Mean, that uncommented only one line at the begin of the programm: BlynkTimer timer;
The same with SimpleTimer library.

That’s a very different issue to the one that you reported when you began this topic.

This line of code is outside of any function, so I don’t think it will do anything. If that is the case then attempting to enable a non-existent timer isn’t likely to produce a good result.

And, as @Blynk_Coeur says, your void loop is incompatible with good Blynk operation.

Thanks for your answer! But I solved this problem some other way, please, close this topic!

When you solve your issue, we need to know how you did.
I think @PeteKnight agree with me.

Ok! I desided not to use BlynkTimer or SimpleTimer. I just added a counter in the void loop(). So, when the counter increases 10 times - it means that 10 seconds passed. (I receive one message per second from other nrf224l01). So we can call the method to send values to Blynk. Like this:

void loop() { 
  Blynk.run();
  network.update();
      while ( network.available()){
      RF24NetworkHeader header;                            
      network.read(header,&data,sizeof(data)); 
      Serial.println("From: ");
      Serial.println(header.from_node);
      if(header.from_node == 1){
        Serial.println("1");
       data1[0] = data[0];
       data1[1] = data[1];
      } else if (header.from_node == 2){
         Serial.println("2");
       data2[0] = data[0];
       data2[1] = data[1];
      }  else if (header.from_node == 3) {
         Serial.println("3");
       data3[0] = data[0];
       data3[1] = data[1];
      }
      counter=counter+1;
      if(counter==10){
        Serial.println("hello");
        counter = 0;
        printValuesToBlynk();
      }
    }
}

I did that because, unfortunately, I could not found out, how to use BlynkTimer correctly.

It’s just my opinion, but I think you’ll be having much worse disconnection issues with that void loop.

Thanks, Pete, I undersatand, that it is better to keep loop() clean. But in this particular case to keep it clean I have to use interrupt pin in nrf24l01 (there is an irq pin there) ant it will be a great problems during implementation this way. So, for now, this program works fine without any disconnections so, maybe, one day, I will implement this with inetrrupts. If I do that, I will definetely share in this branch.
