BlueStar AC support

[PaulAnurag]

Hi Team,

Thank You for sharing these libraries.
There is not any support for Blue Star AC's. Can anyone help me if I want to build .cpp and .h files for Blue Star, how should I proceed with the same. Can anyone help me understand how did you make soo many AC's .cpp and .h files in the first place?

Regards
Anurag

I have got this data from a Blue Star AC Remote. I am not able to understand some of the terminology as in kHdrMark, kHdrSpace, kBitMark, kOneSpace, kZeroSpace and how to calculate them.

Thanks a lot for replying back. I am very new to this and your help is much appreciated.

[crankyoldgit]

Have you tried transmitting the above raw data back to the device to see if the capture works? If not, please so so. (See the IRsendDemo example code)
I say this because that raw data is really weird. 90% of it has a mark signal of about ~1000us then it changes to ~780us.
Similarly the spaces chnage from ~500us & ~2500us to the same point the mark signal changes where it goes to ~6400us & ~3566us.

This could be a capture problem, or it could be just a weird protocol, or two messages mashed together. Either way, your going to need to capture different settings/buttons etc a few times so we can work out what the heck it's doing.
This is not normal enough to be sure we can construct the base protocol off a single message.

Have you been able to successfully decode other IR signals? e.g. TV remotes.

[PaulAnurag]

No, when I give this data to the python code, it gives an error, which you are probably stating what the problem might be.

And I will try to send it back to the device and see if its working or not.

[crankyoldgit]

The auto analyse too only works on certain types of protocols. This protocol/message is not a case it handles.

[PaulAnurag]

I can share with the the .sal file that has been captured using the logic analyzer.

[NiKiZe]

Please read over the instructions given once more. I do understand that it is a lot to take in on first read. But reading it a couple of time should help.

We love to help, but not explaining again what is already asked and explained in the linked documentation.

[crankyoldgit]

Correct. More data is always better, but I have no idea what a .sal file is nor do I have the tools to use it.

@NiKiZe is correct. Please try what we have asked you to try/do/answer etc.

[PaulAnurag]

I apologize for my mistake. Yes I am going to go through your files as well and will get back to this.

[PaulAnurag]

Hey,
I tried sending the data back to device. Its working. The protocol might be different due to which its not decoding. I just wanted to know how the decoding happens and the theory behind it. If you can help me, it would be great.

Regards
Anurag

[crankyoldgit]

That's good news. (That the sendRaw() worked) so it is probably just an atypical protocol method. We'll still need more rawData to be sure how it works as it is so different.

As for how it happens, I suggest you read through our documentation in the wiki section.

For example: https://github.com/crankyoldgit/IRremoteESP8266/wiki/Overview-of-how-the-library-works & #1230
There may be other discussions/issues which already describe how it works too.

And then there is the whole API documentation too.

[PaulAnurag]

Okay I will go through the documentations. Also I will provide more Raw Data for you to give it a thought as well.

Given down is more raw data. I have only changed the temperature, other configurations eg. mode,fan speed etc are the same.
