Hello,
today I managed it to test the ICs again.
It seems that the ICs I got simply do not work. I will get some new ones and test them again.
In fact the presence of the "bad" ICs prevent the TX module from booting. I think it can't even initialize the I²C bus and freezes at some point.

Quote:Out of curiosity, do you have tested it with a regular I²C sensor or with your height of snow interface? Due to the error on the board, is there any chance that D4 and D5 are become in parallel with A4 and A5?I tested both, a regular sensor and my emulated sensor and none works.
