Remove all your code. And start with bare min sketch (edgent example) see if the esp still crashes.

Btw is your power supply capable of providing sufficient power to your esp ? No loose wires ? Is it a dev board ? If not do you have all the resistors to boot the esp ?

Change the interval. All the functions are called at the same time. This may be also one of the reasons.
Give a 2 or 3 second gap between function call’s.

24

I’m using node mcu to test without the development board and the power source is directly from the laptop @Madhukesh

25

Start doing this.

26

@wasemooo4 please do not tag Blynk staff in your posts like this. If you do then your Blynk community account will be suspended.

Dear @Madhukesh , I have commented on Blynk.virtualWrite(vPIN_BatteryVoltage, Voltage);
Problem solved, what do you think could be the cause?

I’m sorry @PeteKnight , I didn’t know it wasn’t allowed

29

Problem solved, thanks everyone, I canceled BlynkTimer and replaced it with SimpleTimer. After all failed attempts, SimpleTimer managed to solve the problem. It seems that there is a problem with BlynkTimer. Please look into this matter from the founding company

30

Even i faced this issue. But i thought that would be because of my poor coding knowledge and wrong coding practices.

31

Thanks for the info. I’ll create the ticket @vshymanskyy FYI.

32

BlynkTimer vs SimpleTimer should be equivalent, the only real difference is that BlynkTimer allocates more timers (and thus uses a bit more of the memory).

Could you reduce MAX_TIMERS and see if it helps?

33

How ever this particular lib seems to crash. Just to prove this I changed the timer lib with others and left the rest of the code untouched ! And the code works just fine. As soon as i switch back to Blynk timer the code starts to crash.

So it seems like something is wrong with blynk timer. May be i am wrong !!

34

What happens if you use a different object name for your Blynk timer - something other than timer, maybe mytimer ?

Pete.

35

Yeah i remember you said me to fo the same in the previous post i had created. And yes i did as per your instruction but no use. Still crashes.

36

This:

37

Thank you dear @vshymanskyy unfortunately I was not able to solve the problem, it reappeared, but the strange thing is that I changed the code and built a new code that contains two resistors to read the voltage of the batteries and I used pzem-004t and this code also causes the nodemcu to collapse. I don’t know why, but I tried the code on blynk legacy It works without any problem

38

When writing a code that controls the relay, there is no problem, but when adding void and calling it in timer, problems and crashes occur sometimes. The code works correctly, but when I turn the relay on or off, the noemcu crashes directly. I hope you understood what I mean because I do not speak English well @vshymanskyy

39

I also have this problem. Suddenly wemos d1 mini crashes and I haven’t found a solution for it

40

@ebda3 please create your own “need help with my project” topic and provide all of the requested information, along with the information that is outputted to your serial monitor when the device boots then crashes,

Pete.

I think there is a power issue. Place a 100uf cap across Vin n Gnd. Seems like the new Blynk is power hungry, even though the code is same.

Is it because we have many header files ? Sounds silly though :confused:.
