Infrared remote library for ESP8266/ESP32: send and receive infrared signals with multiple protocols. Based on: https://github.com/shirriff/Arduino-IRremote/

This library enables you to send and receive infra-red signals on an ESP8266 or an ESP32 using the Arduino framework using common 940nm IR LEDs and common IR receiver modules. e.g. TSOP{17,22,24,36,38,44,48}* demodulators etc.

v2.8.6 Now Available

Version 2.8.6 of the library is now available. You can view the Release Notes for all the significant changes.

Upgrading from pre-v2.0

Usage of the library has been slightly changed in v2.0. You will need to change your usage to work with v2.0 and beyond. You can read more about the changes required on our Upgrade to v2.0 page.

Upgrading from pre-v2.5

The library has changed from using constants declared as #define to const with the appropriate naming per the C++ style guide. This may potentially cause old programs to not compile. The most likely externally used #defines have been aliased for limited backward compatibility for projects using the old style. Going forward, only the new kConstantName style will be supported for new protocol additions.

In the unlikely case, it does break your code, then you may have been referencing something you likely should not have. You should be able to quickly determine the new name from the old. e.g. CONSTANT_NAME to kConstantName. Use common sense or examining the library's code if this does affect code.

Library History

This library was originally based on Ken Shirriff's work (https://github.com/shirriff/Arduino-IRremote/)

Mark Szabo has updated the IRsend class to work on ESP8266 and Sebastien Warin the receiving & decoding part (IRrecv class).

As of v2.0, the library was almost entirely re-written with the ESP8266's resources in mind.

irremoteesp8266's Issues

LG code port problem

Hi

Library is great, but I have strange problem. I ported LG code send function from here: https://github.com/z3t0/Arduino-IRremote/blob/master/ir_LG.cpp
but it is not working. I am sending ir codes to my LG airconditioner from ESP8266. I also have second device based on arduino as ir-receiver for troubleshooting. Both codes, sent from ESP8266 and from oryginal ir remote looks identically in arduino code grabber, but remote is working fine and codes from ESP are being ignored. What am I doing wrong? Maybe I ported code in a wrong way? I just copied function code and declarations...

This is air conditioner samsung... - how correct do this?

ESP resets if delay is used...

When I press and hold button on my remote for about 10 seconds my ESP resets. It only happens when I use some delay in loop. Even example sketch IRrecvDumo contains 100ms delay in loop resulting ESP to reset.
Any ideas to identify source of problem?

i2c interfacing

Hi. Great job with this library, works like a charm.
i would like to ask you if you can help me, or point me in the right direction, to read the ir signals from the decoder, and send them to the ir transmitter via i2c (i/o port expander.. the esp8266-01 is short on ports as you know...). I have made the connection with the expander (MCP23008), tested and everything, but i don't find any clues to go through i2c with the ir codes. Please help me, thank you.

irsend.sendLG() not working.

Hello All, was working with this code:

/*
Blink
Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the Uno and
Leonardo, it is attached to digital pin 13. If you're unsure what
pin the on-board LED is connected to on your Arduino model, check
the documentation at http://www.arduino.cc

This example code is in the public domain.

modified 8 May 2014
by Scott Fitzgerald
*/

include <IRremote.h>

IRsend irsend;

// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin 13 as an output.
pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
Serial.println("0x88C0051");
irsend.sendLG(0x880094D, 38);
delay(10000); // wait for a second
}

But nothing seems to work, I've try alot of samples too, but not working, please kindly assist

irsend.sendNEC problem

I had some problems getting IRServer to send the right codes to my Toshiba Regza TV. I captured all of the remote codes from the manufacturer's remote and plugged them into the IRServer demo. No dice - definitely LED activity, everything was firing fine, just no reaction from the TV. Working my way through troubleshooting, I captured a set of codes from the infrared LED attached to my ES-01 and compared them to the manufacturer's remote:

Manufacturer remote code:
9050,4500, 650,600, 600,600, 600,600, 600,600, 600,600, 600,600, 600,1700, 600,600, 600,1700, 600,1700, 600,1700, 600,1650, 600,1650, 600,1650, 600,600, 600,1650, 650,600, 600,1700, 600,600, 600,600, 600,1650, 600,600, 600,600, 600,600, 600,1700, 600,600, 600,1700, 600,1700, 600,600, 600,1650, 600,1650, 600,1650, 600

Reproduced code:
9000,4550, 600,600, 600,600, 600,600, 600,600, 600,600, 600,600, 600,1700, 600,600, 600,1700, 600,1700, 600,1700, 600,1700, 600,1700, 600,1700, 600,600, 600,1700, 600,600, 600,1700, 600,600, 600,600, 600,1700, 600,600, 600,600, 600,600, 600,1700, 600,600, 600,1700, 600,1700, 600,600, 600,1700, 600,1700, 600,1700, 600,600, 600,600, 600,600, 600,600, 600

The additional eight pulses at the end caused problems. Comparing your example code to Shirrif's example code:

https://github.com/markszabo/IRremoteESP8266/blob/master/examples/IRServer/IRServer.ino#L30]
irsend.sendNEC(code, 36);

https://github.com/z3t0/Arduino-IRremote/blob/master/examples/IRtest/IRtest.ino#L158
testNEC(0x00000000, 32);

I amended 36 to 32, which removed the spare pulses and got everything working.

missing include

I pulled this to use with https://github.com/arendst/Sonoff-Tasmota and could not get it to compile without adding the line:
#include "IRKelvinator.h"
to the file IRremoteESP8266.cpp

Looking for maintaners/collaborators

Dear @crankyoldgit, @sebastienwarin, @sillyfrog, @pintomax, @roidayan, @bakrus, @renno-bih,

thank you for your great help with this project. Recently I have almost no time to work on this library, while more and more people are interested with PRs and issues more and more often. So if some of you have time and willing to help / take over the project, I would be happy to give you push access to this repo. Alternatively if you want to do it on your own github, I can deprecate mine and place a link to the top of the readme. However given the good number of people already using this repo, I would prefer the first solution.

Best regards,
Mark

Problem air conditioner

Hello
The air conditioner uses a raw 199, this has to change the IRremote.h -> #define RAWBUF 100 to 200 and change IRremoteInt.h #define _GAP 5000 change to 50000, the problem is that there are over 300 air and the string only accepts 255 to solve this?

Problem with big number in NEC Code

When I send the code 0x7E817E81 (decimal 2122415745) it works fine (by using the IRSendDemo sketch). When I send codes like 0x807F817E (decimal 2155839870) or 0x817E817E ‭(decimal 2172551550) it doesn't work so I guess it's possible a problem with Long and Unsigned Long numbers as the problem appears (up to where I tested) with codes bigger than 0x7FFFFFFF.

When I try to send 0x807F817E according to AnalysIR this is what gets sent:

unsigned int Signal_1_1[] = {8960,4523,555,1707,533,597,533,597,533,597,533,597,533,597,533,597,533,576,533,597,512,1728,555,1685,555,1685,555,1707,555,1707,555,1685,555,1685,555,1707,555,576,533,597,533,597,533,597,533,597,533,576,533,1707,555,597,533,1685,576,1685,555,1707,555,1707,555,1707,555,1685,555,576,512,597,533,597,533,576,533,576,533}; //AnalysIR Batch Export (IRremote) - RAW

Here you can see a correct NEC code send by the remote (in yellow) and the same NEC code sent by the sketch (in green):

I have no clue what the problem is (other than the size of the number).

Pinout

Can you tell me if the pin conection is GPIO0 ( irsend(0) ) to GND or to 3.3V ? This two possibilits would invert the led status/
In Arduino is generaly is positive GPIO to GND but because the esp8266 can give low current most blink examples use gpio to 3.3V

irsend.mark(0); doesn't seem to work

I've ported some code that previously worked on a Nano to the ESP8266 using this library. However, beam detection using irsend.mark(0); now seems to have stopped working.

Restarting if continues ir received

i like to say thank you for this library creator and supporting members,
its decoding perfectly but ESP8266 Restarting, If receive continuous IR Signal ,
Iam using gpio13 to connect ir receiver(TSOP1738)

New NEC format

Excellent, excellent job. I've been looking for 2 weeks for this library. I don't know why I couldn't find it earlier.

I have Gree Aircon which seems to be using non-standard NEC protocol. I think its called NEC2.

I have successfully used your library to send raw IR but no luck with the hex codes. I think I need to define a new function irsend.sendNEC2(code,bit_size).

I had good luck with: irsend.sendRaw(buffer, sizeofbuffer,38)

The buffer is "Raw: (139) 8996, -4480, 644, -1652, 644, -556, 644, -556, 640, -1656, 640, -560, 644, -1652, 640, -1656, 640, -560, 668, -532, 668, -532, 664, -540, 640, -560, 640, -560, 640, -536, 664, -564, 612, -588, 612, -588, 616, -588, 612, -588, 612, -560, 640, -588, 612, -1684, 620, -1676, 648, -552, 672, -528, 676, -524, 648, -556, 648, -552, 648, -1648, 648, -552, 648, -1648, 648, -552, 648, -552, 648, -1648, 648, -552, 648, -19928, 676, -1648, 644, -556, 644, -556, 648, -552, 648, -556, 644, -556, 648, -552, 648, -552, 648, -556, 648, -552, 648, -552, 648, -552, 648, -552, 652, -1644, 648, -552, 648, -556, 648, -552, 648, -552, 648, -556, 644, -556, 648, -552, 644, -556, 648, -552, 648, -556, 644, -556, 648, -552, 648, -552, 648, -556, 648, -1644, 648, -556, 644, -1648, 652, -552, 648"

Will this library help me send the buffer above in HEX format?

Someone on AnalysisIR experienced the same issue. http://www.analysir.com/joomla/IRforum/viewtopic.php?f=5&t=420#p598

Decode IR with long IR data

I trying to send IR signal from my phone (IR blaster) with raw length about : 72
8973,4552,500,631,500,631,500,631,500,631,500,631,500,631,500,631,500,631,500,1736,500,631,500,1736,500,1736,500,1736,500,1736,500,631,500,1736,500,1736,500,631,500,1736,500,631,500,1736,500,631,500,631,500,631,500,631,500,1736,500,631,500,1736,500,631,500,1736,500,1736,500,1736,500,42447,8973,2289,500,500
And i try to decode that signal from my ESP.
But i can not receive correct data.
This is what i recieved.
{"Code": "6E61198F","CodeType": -1,"Raw":"9150,4650,500,700,500,700,500,700,500,700,500,700,500,700,500,700,650,700,500,1800,500,700,500,1800,500,1800,500,1800,500,1900,500,700,650,1800,500,1800,500,750,500,1900,500,700,500,1800,500,700,500,700,500,700,500,750,500,1800,500,700,500,1800,500,700,500,1800,500,1800,600,1800,500","RawLength":68,"Bits":32}
{"Code": "FFFFFFFF","CodeType": 1,"Raw":"9000,2400,500","RawLength":4,"Bits":0}

I don't know how to learn correct IR signal if that signal is too long.
Sorry because my english not good.

Implement receiving and receiving sample

On the main page the description says "send and receive infrared signals" but I can only find examples for sending, which works great. Please also implement receiving.

Other timings

Hallo,

fine that we now have the library for esp8266.

However: Previously I controlled my stuff with arduino + BT module, it worked flawless. With IRremoteESP8266 the Panasonic PVR did not work. I had to change the definitions to:

define PANASONIC_HDR_MARK 3413

define PANASONIC_HDR_SPACE 1750

define PANASONIC_BIT_MARK 469

define PANASONIC_ONE_SPACE 1244

define PANASONIC_ZERO_SPACE 384

The Samsung stuff worked "out of the box". However, I recognized thet (for my remote) the signals were a bit too long. So I now use these definitions:

//original by Ken Shiriff:

define SAMSUNG_ONE_SPACE 1600

define SAMSUNG_RPT_SPACE 2250

//modified by Sebastien Warin:

define SAMSUNG_HDR_MARK 4500

define SAMSUNG_HDR_SPACE 4500

//and

define SAMSUNG_ZERO_SPACE 580

define SAMSUNG_BIT_MARK 580

May be these timings are depnedent on the individual remotes.

Best regards

RC-MM Protocol For IRremoteESP8266

ESP8266 NodeMCU Backdoor uPWM hack for IR signals wit UART

FYI: we have just published an article on our blog, with examples, showing how to accurately generate hardware based PWM for IR carrier signals on the ESP8266 NodeMCU, using our uPWM method. (hardware based PWM on the ESP8266 is supported from 100Hz to 1kHz (AFAIK). The method we published supports all common IR frequencies & a good selection of duty cycles. Previously all implemetations on this platform relied on software loops to generate the PWM. For anyone with the time available, there is no reason it couldn't be incorporated into the main IRremote repository. Let us know if you find it useful.

Support for Mitsubishi AC?

Hi,

Would it be possible to enhance this library with support for Mitsubishi air conditioning systems? Code is available here: https://github.com/r45635/HVAC-IR-Control

Wrong decoded IR

Hello,

I've used the sample below to decode my SAMSUNG TV IR codes for test, But I can see that the result is not OK and it differs from what is in https://irdb.globalcache.com/Home/Database,
And as IRDB codes are working fine with my IR sender, I guess the codes that below link is dumping are wrong.
https://github.com/markszabo/IRremoteESP8266/blob/master/examples/IRrecvDumpV2/IRrecvDumpV2.ino

Anyone has experience on how to adjust the codes IRrecvDumpv2 ?

RC5 possible issue

Hello,
i have attached an IR LED (http://goo.gl/m9HZkR) to my ESP module.
I am tring to control my tv from internet sending RC5 signals. (read RC5 and codes with an receiver)
TV accepts the IR signal only after 10-15 tries. Read somewhere that RC5 is very sensitive to timing.

Do you have any idea why ?

Thanks.

56Khz

Is there any way to send and receive @ 56Khz with this library ?

Thanks in advance,

Unknown encoding find in my TV remote.

Actually i am using your library.Its works great in decode some of Fan and AC remote.
Whenever i use TV remote.it all time display unknown encoding.Same remote i used decode my raw code via IRremote.h library in my arduino uno board.So, how to resolve this problem?
If i use Arduino uno board then result should be,
Decoded RC6: 1000C (20 bits) <--- Power button pressed

If i use ESP8266 nodemcu then result should be,
Unknown encoding: F5AD0EC0 (32 bits)

So, please help me resolve this problem.
Even i put double slash at //case AIWA_RC_T501: Serial.print("AIWA_RC_T501"); break ;
file than i compare sketch.So, check this problem.

Issue sending NEC codes, but raw works fine

Hey,

So I know my setup is working since sending raw data controls my Seville Classics fan. The IRRecvDemo says that it's getting NEC codes, and some existing code on Github makes me think it's NEC, but whenever I send NEC out the fan won't respond. If I send the raw data it works fine.

Here's example output from the receiver:

Can anyone help?

Carrier frequency inaccurate

I am just setting up an MQTT-to-IR bridge using a Wemos D1 Mini, but was unable to control our old Panasonic CRT TV. Hooking up the oscilloscope, I found out that the actual carrier frequency was about 32.5kHz instead of the configured 35kHz. The actual remote even uses 36.5kHz. This discrepancy was apparently enough so that the TV did not react at all.

As a quick and dirty fix, I changed the timing in IRsend::enableIROut(int khz) from 500/khz to 465/khz. This gave me a pretty accurate carrier frequency for 35 and the TV works, but I expect that the issue is rather related to additional delays, so an offset would be more appropriate to get accurate results on other frequencies.

Please mark release to add in to Arduino library manager

This library should have a tag to add it into Arduino library manager.

Having issues with sendGC

I'm using sendGC as I'm converting from a iTach. I have it working with 3 other devices but will not control an Onkyo AMP. Exact same codes I'm using through the iTach so I know the codes are good. Any ideas what to try or how to analyse the IR signal?

Thank you!

Where are the IRsend methods mark() and space() defined?

I see only this in IRremoteESP8266.h:

VIRTUAL void mark(int usec);
VIRTUAL void space(int usec);

I need to modify these, but I don't know where...

GPIO interrupt attach in enableIRIn overrides pre-existing interrupt handlers

I couldn't find any documentation but it appears that ETS_GPIO_INTR_ATTACH(gpio_intr, NULL) overrides any pre-existing interrupt handlers.
I will create a pull request with a (potential) fix.

Bug in read_timeout method, "eating" the initial mark duration and producing result different from Arduino...

Hello,

I think there is a bug at line 487 in IRremoteESP8266.cpp, the duration of the mark is not saved and then the data received/interpreted is not the same than the one we get when using iRemote with and arduino board. It also fails to decode most of the protocols I have been able to try.

if (irparams.rcvstate == STATE_IDLE) {
        irparams.rcvstate = STATE_MARK;
        irparams.rawbuf[irparams.rawlen++] = 20;        
    }
    else if (irparams.rawlen < RAWBUF) {
        irparams.rawbuf[irparams.rawlen++] = (now - start) / USECPERTICK + 1;
}

When state is STATE_IDLE then (now - start) / USECPERTICK + 1; should be executed too so that we save the duration of the mark in the buffer.

I changed the code to this and now the protocols I try (Samsung, LG, ...) are successfully decoded, and unknown protocols return me the exact same value that I have when I use the arduino version of iRemote.

I am not sure if moving the test irparams.rawlen < RAWBUF outside is ok, do we have a case where the state can be STATE_IDLE and we have irparams.rawlen not 0 ?

if (irparams.rawlen < RAWBUF) { 
   if (irparams.rcvstate == STATE_IDLE) {
      irparams.rcvstate = STATE_MARK;
   }
   irparams.rawbuf[irparams.rawlen++] = (now - start) / USECPERTICK + 1;
}

Not able to send raw data using dynamic arrays

I'm using this library to send ir data to a device, the raw data is sent to esp via a server and esp receives the raw data in a char array which then I convert to unsigned int array as it is required by irsend.sendraw function. But I'm not able to see any results with this method.Whereas when I hardcode the array and then send that, everything works fine. So can anyone help me? Where I'm going wrong?

I. Sorry to ask you that but do you know how to work an ir receiver with esp lua code ?

Thanks for your help

PLEASE HELP, sendRaw, send GC.

Currently using Arduino UNO with iRemote library to send two sets of pulses by an IR LED connected directly to pin 3 and GND, everything works smoothly.

Now I wanted to use the D1 mini, because is equipped with WiFi, but if I send the same code sequence with the library IRemoteESP8266, always with the IR LED connected directly to pin D3 and GND, nothing works.
I enclose the two sketch used to tests:

I also tried the sendraw but did not work.

Receiving is not working after irrecv.disableIRIn() and irrecv.enableIRIn()

Receiving not working after disabling and re-enabling receiver..

I have attached both the IR decoder for receiving IR codes and IR LED to send IR codes.
When I send the code then it is also received back by receiver. To avoid this I am trying to disable receiver before the sending and enable receiver after sending.

    irrecv.disableIRIn();
    irsend.sendRC5(code, 12);
    irrecv.enableIRIn();

after this I cannot receive any IR code.

hey Mark!

thank for sharing this!
i have a question. is it possible to send a raw data?
if so, is it limitied to a number of chars?

thanks you

Suggestion to the README file - Installation method.

There is a new way of adding libraries via the GUI.

1. Download the ZIP file
2. In Arduino IDE menu: Sketch | Include Library | Add .ZIP Library... point to the downloaded file and it will be added to the Arduino IDE.

air conditioners no work

Any help is welcome thank you

ES-01 pin usage

I'm just finishing up my ES-01 build of an IRServer. The IRServer code currently uses GPIO 0 to flash the infrared LED. I found this inconvenient due to the pin being pulled low by the attached LED on every boot. This causes the ES-01 to go into flash mode, preventing normal running. I could get the thing to work but I had to disconnect the LED, reboot the ES-01, then reconnect the LED after boot.

I managed to get everything working smoothly on an ES-01 using GPIO 3/RX as the LED pin. This works almost without modification, but it did require me to disable the RX pin in the serial.begin() function.

https://github.com/markszabo/IRremoteESP8266/blob/master/examples/IRServer/IRServer.ino#L54
Serial.begin()

Revised version:
Serial.begin(115200,SERIAL_8N1,SERIAL_TX_ONLY);

This approach might be worth mentioning in a comment somewhere.

IRsend.sendSony() problem

Sony TV does not see the transmission from sendSony(). I simply use the IRSendDemo to send the following code to the Sony TV:
irsend.sendSony(0xC90, 12); // Volume Down

In order to debug the issue I did the following:

• Built another ESP8266 with IR Receiver and the sample IRrecvDumpV2. It recognized the codes from both the original Sony Remote Control, as well as from my ESP8266 transmitter described above. Below are 3 samples of each.
• Previously tried the same IR LED on an Arduino build and saw that the Sony TV reads it, so the LED has the correct wavelength (940).

I presume this may be some timing tolerance issue, but I am not savvy enough in the IR codes to spot the problem. Please help.

Thanks,
Jordan
P.S. 3 samples of readings by IRrecvDumpV2 from IRSendDemo and original Sony Remote:

Library not properly decoding Samsung remote

I'm trying to use the library with a Samsung remote, and this is the data I get for a volume down key on the remote:
Code: 83B19366
Raw: rawData[67] = {4550,4550, 600,1700, 550,1750, 550,1750, 550,600, 550,600, 550,600, 550,600, 550,600, 550,1750, 550,1750, 550,1750, 550,600, 550,600, 550,600, 550,600, 550,600, 550,1750, 550,1750, 550,600, 550,1750, 550,600, 550,600, 550,600, 550,600, 550,600, 550,600, 550,1750, 550,600, 550,1750, 550,1750, 550,1750, 550,1750, 550};

If I try to send that signal using the hex code and the sendSamsung function, nothing happens. I am able to make it work though by sending the raw data.

I moved back into the original IRremote - which this library was based on - with a regular arduino, and I got a different hex code for the same volume down key: E0E0D02F. And if I use this code with the IRremoteESP8266 library and the sendSamsung function, it does work.

Is there a reason for the IRremoteESP8266 library not properly decoding - or at least not generating the right hex code - for the Samsung remote? Can someone provide me guidance on how to fix this?

Thanks,

Christian

IRGCTCPServer example questions

How is the IRGCTCPServer example supposed to work?
I'm a bit new to ESP8266 and I had a question about this example:

• Is the example missing an explicit command to connect to WiFi? (something like WiFi.begin?)

I'm very excited about this project!!! I am looking forward to being able to trigger IR commands from the terminal if that is possible. Thanks!!!
