Blynk Ir Connection - NEED HELP

Need Help With My Project
1

Hi,

I am trying to switch on my A/C from blynk. When I tested it out without Blynk it worked good, so the Ir codes and Ir led are connected good. The problem is when I put Blynk on top of it, it is not wokring. Here I my code for sending Ir signal

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>
#include <IRremote.h>

char auth[] = "xxxxxxxx";
IRsend irsend;

unsigned int irTemp17 [] = {3050,1550, 550,1050, 500,1050, 550,250, 550,300, 500,300, 550,1050, 500,300, 550,250, 550,1050, 500,1050, 550,250, 550,1050, 500,300, 550,250, 550,1050, 550,1000, 550,300, 500,1050, 550,1000, 550,300, 500,300, 550,1000, 550,300, 500,300, 550,1050, 500,300, 550,250, 550,300, 500,300, 550,250, 550,300, 500,300, 550,250, 550,300, 500,300, 550,300, 500,300, 550,300, 500,300, 550,250, 550,250, 550,300, 550,1000, 550,300, 500,300, 550,1000, 550,300, 550,250, 550,1000, 550,1050, 550,250, 550,250, 550,300, 550,250, 550,300, 500,300, 550,300, 500,1050, 500,1050, 550,1000, 550,300, 500,300, 550,300, 500,300, 550,1000, 550,300, 500,1050, 550,250, 550,300, 550,250, 550,300, 500,300, 550,250, 550,300, 550,250, 550,250, 550,300, 500,300, 550,300, 500,300, 550,300, 500,300, 550,250, 550,250, 550,300, 550,250, 550,300, 500,300, 550,250, 550,300, 500,300, 550,300, 500,300, 550,250, 550,250, 550,300, 550,250, 550,300, 500,300, 550,250, 550,300, 550,250, 550,250, 550,300, 550,1000, 550,1050, 500,1050, 550,1000, 550,300, 500,300, 550,1000, 550,300, 500};

void setup()
{
  Serial.begin(9600);
  Blynk.begin(auth);
}

BLYNK_WRITE(V12) {
if(param.asInt == HIGH) { 
irsend.sendRaw(irTemp17, sizeof(irTemp17) / sizeof(irTemp17[0]), khz);
}}

void loop()
{
  Blynk.run();
}

Anyone knows what is the problem. Thanks in Advanced…

That looks pretty much OK to me. I used IR with Blynk too to switch on/off my Amplifier and TV and it worked very well. I can’t really see what’s going wrong here. I’m thinking it is a timing issue. I think that @Pavlo uses something similar to control his A/C, maybe he knows?

if(param.asInt == 1)

Hi. Thanks for the reply I tried that too instead of high I wrote 1 but it still didnt work

5

It’s param.asInt() now that you mention it :slight_smile:

6

HI, thanks for the help but I tried but it still isn,t not working. @Pavlo maybe you know

Sorry, have a little time to review your code. Here is my AC controller with Particle Photon. Please also mind that I’m not the best coder in the world. I just make it work and forget )
