SOLVED!!! i've increased the size of the char from 4 to 7 and i get values!!!

Show FULL code

And what is the value of rpm whe the problem is happening ?

itoa works, I use it every days

I think but i could be wrong that the issue is related the way which your app handles interrupts. It isn't able to work with them,
only rounds of engine uses interrupts and so do not work.

Five for both char variables.

What the length of RemoteXY.giri ?

I've just focused my attention on that flag, thanks.

Some debug:

1) when i connect, the flag goes 1 and i control the RGB led;

2)On the app i put 2 char boxes [5], one for the temperature (i read the value no problem) and the other to show RPM of the engine. This second box shows always a flashing "00" and when it starts to generate numbers (rounds of engine) suddenly the connect_flag goes to 0( i need to reenter in the app).

I used your guide to convert from int to char with sprintf, itoa doesn't work. I see right values in my serial monitor, but not in the app (no RPM, yes temperature).

This is my code, hope it helps:

if (currentmillis - lastmillis <= interval){ 
 detachInterrupt(IR);
 rpm = half_revolutions * ((60000/(currentmillis - lastmillis)));
 //Serial.print(rpm); 
 //Serial.print(" RPM");
 //Serial.print("\n");
 half_revolutions = 0;
 lastmillis = currentmillis;
 attachInterrupt(IR, rpm_fan, FALLING);
  }
sprintf (RemoteXY.giri, "%d", rpm);

ICACHE_RAM_ATTR void rpm_fan(){
  half_revolutions++;
 }

if (RemoteXY.connect_flag != 0) {
  // connection established
}
else {
  // connection off
}

I'm working with a nodemcu v3 for a project to use at school during open events. My project is done with a RGB led, a Dallas temperature gauge, a DC engine (PWM)+photo resistor+laser beam [i read spins], 16x2 LCD.
So the led lights randomly, the engine runs randomly too and on the display it shows the temperature and rounds per minute. This happens when "NO CLIENT" is connected to the nodemcu,
While it someone is connected to nodemcu, it will being drived by the app.
So i don't know which syntax to use for my "if" cicle:

if (??????????????????????)
  {
  RemoteXY.rgb_1_r=random(0,255);
  RemoteXY.rgb_1_g=random(0,255);
  RemoteXY.rgb_1_b=random(0,255);
  RemoteXY.slider=random(0,100);
  }

I tried:

WiFi.status() != WL_CONNECTED
!client.connected()
WiFi.waitForConnectResult() != WL_CONNECTED
WiFi.localIP().toString() == "0.0.0.0"

Which is the compatible function to use with the RemoteXY library??? I tried calling the WiFi.begin() function too.
Thanks
