Hi, I have followed the instructions for the realization of the project but when I try to pair the pro micro to the keyboard nothing appears on the serial monitor (it remains completely empty).

The tests done through the board_qc file give positive results.
Then as specified here I load the file on the board and I turn on my magic keyboard but nothing happens.

I thought it was the bluetooth key the problem so I bought the one recommended here but the problem remains.

This is the bluetooth dongle

Am I doing something wrong or is there a different problem?
