I2C sweep check practically all numbers

The processor is a NUC131LD2AE.

What core do you use, and what board do you select?

{ Wire.beginTransmission (i);
if (Wire.endTransmission () == 0)

There may be issues with the Wire library implementation with that board when a 0 length write is executed. Try sending some data.

I wouldn't get my hopes up, but you can try

{ Wire.beginTransmission (i);
Wire.write(1);
if (Wire.endTransmission () == 0)
