Thank you very much, the "min_repeat" definitely helped with the raw data. I
for the first time succeeded to have one signal received and well
interpreted by the box.
Now it's still random and it seems the learning is not optimal. irw reacts,
but when using one key it may give several different results.

I will continue to fine tune all that.

One question though, is there a way to convert raw data into hex ones ? It
may help to compare with the data generated with XMP.
