If IR emitter has WiFi chip enabled, IRrecvDumpV2 receives many broken packets

Version/revision of the library used

version 2.8.4

Describe the bug

I'm using the COOLIX protocol to control a Beko Air conditioner (with remote RG52A9/BGEF). My setup is a ESP32S2 Devkit-C sender with a Grove IR emitter and a ESP32S2 Devkit-C with IRrecvDumpV2. Everything works as expected and I can read packets and control my AC successfully.

However, when I enable the WiFi chip of the sender device, the receiver reads many broken packets. So, it works perfectly without WiFi, but when I connect to my WiFi network, the receiver starts to read many broken packets.

To Reproduce

Check this example https://github.com/Ks89/ir-esp32-example It contains two projects:

  • sender: is the project connected to the IR Emitter
  • receiver: is the official IRrecvDumpV2 example

If you comment lines from 37 to 41 (https://github.com/Ks89/ir-esp32-example/blob/9559e02876779aa2ece39f40b3204452f6ffca6b/sender/sender.ino#L37) in this way:

//WiFi.begin(ssid, password);
//while (WiFi.status() != WL_CONNECTED) {
//    delay(500);
//    Serial.print(".");
//}

it works as expected with no broken packages, otherwise not.

Expected behaviour

If a send a signal from the sender to the receiver I should be able to read valid packets also with WiFI enabled, instead of many broken data:

The sender code is very easy, because I send in a loop the same command:

// init
ac.begin();
ac.on();
ac.setTemp(20);
ac.setFan(FAN_AUTO);
ac.setMode(HEAT_MODE);

// call send in a loop every second
ac.send();

Feel free to ask. I can reproduce this problem again and again.

Something is screwing around with the timing system. i.e. The pulses produced are not as they should be. This is probably due to the Wifi operating in the background while sending. In theory, it shouldn't interrupt it or cause a problem.

As I don't think I have an ESP32-S2 unit handy I'm going to have to get you to test a few things. First. Let's start with adding a ac.calibrate(); in your init() clause. The default timings for an ESP should be the same, but I never tested it on an S2 variant.

I doub't that will fix it but. I'll get back to you with some more ideas in a bit.

crankyoldgit avatar Nov 25 '22 04:11 crankyoldgit

Looking into this more, it seems the S2 being a single processor is more susceptable to causing delays in bit-banging (which is what we are doing to generate a PWM signal on the ESP chips). So it looks like this won't be properly fixed till we implement sending via the RMT hardware. I guess I'll need to find some time and up the priority on that.

crankyoldgit avatar Nov 25 '22 05:11 crankyoldgit

Hi @crankyoldgit thanks for the info. I tried to add ac.calibrate(); in setup() before ac.begin() but it still not working. The same, also with ac.calibrate(); after ac.begin().

Looking into this more, it seems the S2 being a single processor is more susceptable to causing delays in bit-banging (which is what we are doing to generate a PWM signal on the ESP chips). So it looks like this won't be properly fixed till we implement sending via the RMT hardware. I guess I'll need to find some time and up the priority on that.

Ok, yes this is a big problem, because ESP32 S2 is very common today (S3 is still quite rare, but it's already available on the market). I have many of them in my home. Is the first ESP32 DevkitC supported? If you want to work on this issue with high priority I can help you to do some tests on different ESP devices. I have the first Esp32 devkitc (Az-delivery), ESP32S2 (official by Espressif) and I can find an ESPS3 DevkitC if required.

Ks89 avatar Nov 25 '22 09:11 Ks89

Tested on all 3 versions of ESP32 DevKits and these are the results:

  • ESP32 DevKit-C (the first version with ESP32-WROOM-32): OK
  • ESP32 S2 DevKit-C (ESP32-S2-SOLO): not working as described above
  • ESP32 S3 DevKit-C (ESP32-S3-WROOM-1): OK

Ks89 avatar Nov 26 '22 13:11 Ks89

Is ESP-32S affected?

Onepamopa avatar Dec 15 '22 21:12 Onepamopa

No idea. Is it a sort of mid version between ESP32 and ESP32S2?

Ks89 avatar Dec 15 '22 23:12 Ks89

Who knows.... here's it:

esp-32s

Onepamopa avatar Dec 15 '22 23:12 Onepamopa

If it is dual core (2 CPUs) then you'll probably be fine

crankyoldgit avatar Dec 15 '22 23:12 crankyoldgit

aren't all esp32's dual core ?

Onepamopa avatar Dec 16 '22 06:12 Onepamopa

aren't all esp32's dual core ?

No. e.g. The ESP32-S2 is a single core, hence why we are have an issue on that platform when the CPU needs to multi-task.

aren't all esp32's dual core ?

No. e.g. The ESP32-S2 is a single core, hence why we are have an issue on that platform when the CPU needs to multi-task.

Isn't ESP8266 also a single-core board? Why doesn't it have an issue?

Onepamopa avatar Dec 19 '22 07:12 Onepamopa

Is there any chance that this maybe is something similar as #1995 where "the pin used was the issue"
