Can I see the sketch ?
The sketch you used with blynk edgent.

I will give it a try as soon as possible, and I will let you know if I figure it out.

It’s a good idea, thank you, I’ll give it a try

@ebda3

It’s a good idea

No, it’s a bad idea that uses four times more memory than necessary.

Pete.

[PeteKnight]

@Bisri please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly
Triple backticks look like this:

I Think Can Using More Than Sistem Delay Interval(4 Or 5), But With Using Same Delay Interval,

1 Sistem Timing For 1 Function Or Methode Algorithm,

When Using 2 Sistem Timing Interval, But Using Different Delay Or Not Compability(Count Or Value Timing 1 And Timing 2)Can Make Project Crash,

What is the best way to avoid a breakdown in your opinion?

Sorry, I don’t understand any of that.

@ebda3

It depends what’s causing the “breakdown”.

On the subject of timers, you need to understand the capabilities of BlynkTimer and the fact that you need to avoid timers that coincide at the same point in time. You are using a single threaded MCU that can only execute one code instruction at one time. You also need to understand how long each of your functions takes to execute, so you can stagger your timers accordingly. You should probably read this…,

Using BlynkTimer or SimpleTimer

Many users seem to struggle with the basic concepts of using BlynkTimer in their projects, despite the excellent discussions and tutorials that exist on this forum, so I thought I’d write a guide that will hopefully help clarify things. It’s rather long, as it attempts to explain the reasoning behind why and how we use timers, and covers some more advanced subjects, but I’ve tried to organise it in a way that helps people to find answers to specific questions… Why use a timer at all? Let’s say …

Pete.

[ebda3]

@PeteKnight

يعتمد ذلك على سبب “الانهيار”.

فيما يتعلق بموضوع المؤقتات ، تحتاج إلى فهم قدرات BlynkTimer وحقيقة أنك بحاجة إلى تجنب أجهزة ضبط الوقت التي تتزامن في نفس الوقت. أنت تستخدم MCU واحدًا مترابطًا يمكنه تنفيذ تعليمات رمز واحد فقط في وقت واحد. تحتاج أيضًا إلى فهم المدة التي تستغرقها كل وظيفة من وظائفك في التنفيذ ، بحيث يمكنك ضبط المؤقت وفقًا لذلك. ربما يجب أن تقرأ هذا … ،

Thank you but the crash only happens in blynk edgen

[PeteKnight]

Blynk Edgent has more functionality, so may be less forgiving of bad coding.

Pete.

[Bright_Adinkra]

Please is the void loop save with the code in
I thought blynk want clean void loop ?
I want to known please

[John93]

@Bright_Adinkra you should keep your void loop clean as possible for a good reason, check this out :
https://docs.blynk.io/en/legacy-platform/legacy-articles/keep-your-void-loop-clean

[Bright_Adinkra]

Yes but you’ve put code there

[John93]

You mean blynk.run and timer.run ?

[Bright_Adinkra]

You post 4days ago telling the guy “try this”

[Bright_Adinkra]

Which you did some Checking WiFi connection in the void loop

[John93]

Incase you didn’t notice we used if statement, so the code will check the internet connection first and If you are not connected then the offline mode will be activated.
