Good morning,
Used in 3.3V mode and removed JP2 the red let flashes sending sequence.
The converted string is:
{418,1254,418,1254,418,1254,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,418,418,1254,418,418,418,418,418,1254,418,418,418,418,418,1254,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418,418,418,1254,418,1254,418,418,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418,418,418,1254,418,1254,418,418,418,1254,418,418,418,418,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418,9532,418,1254,418,1254,418,1254,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,418,418,1254,418,418,418,418,418,1254,418,418,418,418,418,1254,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418,418,418,1254,418,1254,418,418,418,1254,418,418,418,418,418,418,418,418,418,418,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418,418,418,1254,418,1254,418,418,418,1254,418,418,418,418,418,418,418,418,418,1254,418,1254,418,1254,418,1254,418}
any other advice?

Used in 3.3V mode and removed JP2 the red let flashes sending sequence.

I meant to try this in 5V mode, as you said it was already working in 3V3 mode tih the jumpers inserted.

The converted string look OK.

Some comments:
- This signal seems to be very unusual, because it does not appear to have a header. A header is used to turn on/activate the IR receiver before the data signal arrives.

I mentioned this earlier..... (as a test you could try to put 9000,4500 before the existing signal...like {9000,4500,418,1254,418,1254...)


..What did you use to record the signal? I believe you may have an A.IR Shield ESP32 TRx. If so, record several different signals for this device and email me the output from AnalysIR via Menu->File->Save Session

Use A.IR Shield ESP8266 and AnalysIR software.

I'll try as soon as possible

OK I looked at those signals and they all have NO Header(leader), which is very unusual & could lead to issues.

Please try sending some of them with the Shield directly from AnalysIR (using the firmware we provided)

Also, please email me the sketch you are using to record the signals. (Just in case you are using the worng one)

Sorry for the wait, I tried entering the initial codes 9000.4500 and now it works.
Thanks for your help

wow!

....that was really a long shot.

The reason it works is that IR receivers usually need a header/leader to get the AGC activated, before the data arrives.

Without that, it is likely the first data bit will be ignored.

Thnaks for the update & glad it is working for you now.
