Disconnected NodeMCU

Ellis_Bosisio · February 10, 2017, 11:49am

Hi all,
I’m using a Node MCU v2 and Blynk to create a unique remote control for my house.
Everythink works pretty well and I’m able to control differente device like TV, DVD, HiFi and so on.

To keep the user interface simple I introduced a menu (bottom of UI) that select the device;
if TV is selected than the IR code sent from ON/OFF botton is the right one for TV; if you move from menu to DVD the same button (ON/OFF) will control the DVD player. …and and everythink works fine.

Now, to complete my project I decided to introduce colors… The bottom menu everytime a device is selected move the color of active button to the dedicated color.

HERE A SCREENSHOT:

EX: TV is green and DVD is red.

If I select TV from device the ON/OFF button become green. If I select DVD the ON/OFF button became red. This is super helpfull in terms of usability.

Now I got a problem… I probably introduced to many call to Blynk and I’m frequently disconnected. (is it correct?)

I don’t think is a connection problem is this I need the <SimpleTimer.h>… I gave a look to https://github.com/blynkkk/blynk-library/blob/master/examples/GettingStarted/PushData/PushData.ino but I don’t understand very well how to implement it.

this is my code; where/how I have to implement the simple timer:

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
// IR remote
#include <IRremoteESP8266.h>

char auth[] = "ac0c58077892411bae46ed5cd4743f76";

SimpleTimer timer;

@Ellis_Bosisio the PushData example has a link to the SimpleTimer docs on Arduino and Blynk provide the SimpleTimer library with each of their releases. That is becuase “you can’t Blynk without learning how to use SimpleTimer”. It’s as simple as that.

Maximum consecutive setProperties for a decent processor like the ESP is 4, maybe less for others.

So keep a maximum of 4 setProperties for each case, start a timer and send the other 4, then stop the timer. Trial and error will give you the pause time between the first 4 and the second 4 but perhaps start at 100ms.

You can change the baud from 9600 to 115200. 9600 is only required for inferior MCU’s / connection methods.

Hi Costas,
thank you for your quick answer.
I tried to implement as you proposed the simpletimer library.

I need a little support on coding. It’s something pretty new.

I tried to move the device selector (V1) into a void called void timedevice() but it generates problem.
I don’t also understand how to pause after 3lines …where I’m wrong…?

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space

#include <BlynkSimpleEsp8266.h>

You cannot put BLYNK_WRITE() functions inside other functions like void timedevice()
They must be on top.

You need to limit the number of setProperty requests that go out ‘instantly’. When you have the following:

Blynk.setProperty(V2, "color", "#D3435C"); //RED POWER
Blynk.setProperty(V3, "color", "#D3435C"); //RED SOURCE
Blynk.setProperty(V3, "label", "HOME");
Blynk.setProperty(V4, "color", "#D3435C"); //RED SOURCE
Blynk.setProperty(V4, "label", "LEFT/RIGHT");
Blynk.setProperty(V5, "color", "#D3435C"); //RED SOURCE
Blynk.setProperty(V13, "color", "#D3435C"); //RED SOURCE
Blynk.setProperty(V15, "color", "#D3435C"); //RED SOURCE

you end up flooding your hardware (not the server) and your poor little ESP8266 has to drop connection.

Potential fix, get an ESP32 (it has 2 cores, 1 entirely dedicated to keeping you connected).

SimpleTimer fix, write a simple function containing 3-4 (experiment) setProperty calls only.

void mySetPropertyFunction2a(){
   Blynk.setProperty(V2, "color", "#D3435C"); //RED POWER
   Blynk.setProperty(V3, "color", "#D3435C"); //RED SOURCE
   Blynk.setProperty(V3, "label", "HOME");
   Blynk.setProperty(V4, "color", "#D3435C"); //RED SOURCE
}
void mySetPropertyFunction2b(){
   Blynk.setProperty(V4, "label", "LEFT/RIGHT");
   Blynk.setProperty(V5, "color", "#D3435C"); //RED SOURCE
   Blynk.setProperty(V13, "color", "#D3435C"); //RED SOURCE
   Blynk.setProperty(V15, "color", "#D3435C"); //RED SOURCE
}

Then you would write:

case 2:               // Item 2 - DVD
  pinValueV1 = 2;
  timer.setTimeout(50, mySetPropertyFunction2a); // perform the first function almost instantly
  timer.setTimeout(400,mySetPropertyFunction2b); // perform the second function 400ms later (experiment)

Costas · February 10, 2017, 7:44pm

@Ellis_Bosisio from the code provided by @jamin you only really need1b and 2b (not 1a, 1b, 2a, 2b) functions with a 300ms timeout as the first 4 setProperty() calls can be left in for case 1 and case 2. 200ms still crashes an ESP.

You could hook up a Blynk slider to determine the minimum setting between 200ms and 300ms below which the ESP crashes. Saves you having to keep changing the sketch to determine the optimum timeout value.

Jamin · February 10, 2017, 7:46pm

I was going to do it like this, but though it might have been too confusing explaining the b part of it without the a part.

Costas · February 10, 2017, 7:48pm

@Jamin fair point, but just call them 1 and 2, forget the a’s and b’s

BlackTiger · February 10, 2017, 10:00pm

Hi.
And according to you which would be the most suitable processor to avoid this lack of power ???, maybe with an Onion Omega 2 would not have these problems ??

a greeting

BlackTiger.

Costas · February 10, 2017, 10:04pm

@BlackTiger I posted a few days ago that I would wait 6 months before considering an Omega 2 unless you are a serious hacker.

The ESP’s are fine and it’s just a case of working with their limitations. I wouldn’t go looking for other hardware. ESP32’s will be better, but again I wouldn’t but them yet either.

Ellis_Bosisio · February 11, 2017, 3:01pm

Hi all, thank you for all feedback, and thanks also for the deep explanation of the problem.
I opted to limit the ESP. It’s the cheapest and quick.

That said I made al the suggested changes. To avoid problems I created more void function and increased the “delay” between functions. Now code is more stable but I’m still frequently disconnected. I don’t understand why. there are huge gaps between functions now.

Here the code. Where I’m wrong?

Yes confirmed. now is working perfectly.
I think the problem was in where they void funtion was in my sketch. Thank you so much.

I’ll put some picture/video in the Project mad with Blynk area when everythink will be done.
