ESP32 / ESP8266 FreeRTOS tasks issues

[Bobby2000]

I am using the library for a project on an ESP32 using the Arduino framework. I am also using FreeRTOS multitasking, and sending IR commands from a sub task. However I am having some issues where commands are not being received correctly, or more likely send correctly. I guess this is due to the timing critical code being interrupted by the scheduler. I have made some changes to the library code in my project witch, if used with an ESP32 or ESP8266 MCU, will encapsulate the timing critical code in a FreeRTOS critical section, preventing the scheduler from interrupting the task while sending an IR command. This solved my issue.

I am not sure if this is a unique issue that I am the only one facing? Or if other people have had similar issues? Anyway I would be happy to share my changes or to create a PR if this would add any value to the library?

Searching for RMT and seeing issues where this is mentioned gives a hint about similar issues, and the consensus is to use RMT to have this fixed. But if you have a different workaround for this and can create a PR that would be appreciated, if not used as is, it can at least be source for discussion and ideas.

Ok, I have created a branch from Master and added my updates. However I dont have the rights to push the branch? Do you have a different proces for PR's ?

If you do not have write access to a repo, you have to fork first, then you push to your fork which you can then create a PR from.
https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request

So fork this project so you get a "clone on github" that you can write to, you can then add that fork as a different origin, and push to that origin. From Cli I would do:

git origin add Bobby git@github.com:Bobby2000/IRremoteESP8266.git
git push Bobby

And then follow the suggestions that git and the github server respons with.

I have created a PR, take it for the workaround it is :) Clearly the RMT approach is the better option. Also, seems like the Arduino ESP8266 package does not have FreeRTOS, so this only works for the ESP32.

Try the branch mentioned in #2243 and let me know how it goes for you.
