Raw data unrecognized by air conditioner

[ffoo31]

Hi everybody

I am new to this forum
when I try to read the signal from the remote control of my climatieur split system, I have problems

equipment used:
1- Arduino UNO model E3
2- TSOP 1838.
when I press the OFF button, in the same status "TEMP, FAN, SWIG, MODE", the serial Port shows me a different result each time gross.
HEX the result is the same, but the raw data changes for the same button and same status.
for sending, nothing works or HEX, or raw data
I send you in attachment the raw data for OFF button
what is the problem in your opinion.?
Thank you

It looks like you have hit the 100 RAWBUF limit of IRremote.

You can adjust the setting for RAWBUF or use our script to record the signals, see:

Of course AnalysIR will do a much better job and clean(auto-correct) the IR signal when recognised.

Thank you for your help
I used your script "see attached", are the results

when I let BAUD 115200, I will have the resulat displayed in TEST1 file.
As I change baud 9600, I will have the results displayed in TEST2 file.

you notice that the resulat exchange for the same button
NB: OUT is plugged into pin2, V + is in 5V, I tried it with 3v same result occurs
Thank you

Obviously 115200/Test1 is the correct version...ignore TEST2/9600

Some of the signals you are capturing look like complete signals.

However, there seems to be an issue with your IR receiver.
Please post the make & model # (+link) of your IR receiver and how you have it wired up.

Your IR receiver seems to be struggling with this signal.

ooooooops...I see that you posted this already. LINK http://www.bsselektronika.hu/pdf/opto/tsop1838.pdf
I had a quick look at the data sheet and this is a VERY old model of IR receiver & it seems will not support a signal like yours very well.

Check out the receivers we provide on our website https://www.analysir.com/blog/product/i ... rter-kits/
and either the TSOP34438 or TSSP4038 should work fine. You may be able to source them directly.

We also have a range of modules and shield available now in our Shop (LearnIR & A.IR Shields) that would work well.

Good evening,
I changed the IR receiver, and I tied the result to a file.

I did the test with 5v and 3v
the codes change for the same action but there's lookalike
your opinion?
Merci

[AnalysIR]

Yes they look a lot better.

Stick with 5V if you are using an Arduino UNO.


Did you try sending the signals using sendRAW ?


Please post the make/model# of the AirCon unit and the remote.


PS: see this blog post which may be of interest/relevance https://www.analysir.com/blog/2014/03/2 ... ignal-lag/

Thank you again IRANALYSE
before sending the signals is that this is normal code changes each time? 195 raw data is limited or it is the correct code.
My air conditioner is TAURUS, Spanish model
his remote is attached.

for frequency, I use 38kHz?
thank you very much

[AnalysIR]

Yes it all looks good.

96 bits of data = 8Bytes

I dont have enough info for the carrier frequency, but 38kHz is typical for 90%+ of AC units.


Just try sendRAW and post back if it works or not.

[ffoo31]

hi friends especially AnalysIr
I sent my raw data to AC, ooops it works,
OFF is good, ON is good for all modes.

I still have that bow to your skills and kindness.

I will use all the functions in the event of problem, I come to you.
thank you very much

[AnalysIR]

Great news...glad it is working for you

It would be helpful if you could upload a complete set of signals from your remote, as follows:

- each temperature from 16-30 degC
- 2 captures from each of the buttons

It would also help to identify each signal....tnx
