    Hi

    How have you added the SPI pins you're using in your overlay file? You should use pins (P0.08-P0.12) to take advantage of the SPIM4 instance, and that needs to be reflected in your overlay file as explained in steps 2.1 and 2.2 of the Academy course you're referring to. Also, please show me a picture of how you have connected the BMP sensor to your nRF7002DK exactly, as something isn't set up correctly if you're not able to write the addresses correctly.

    Best regards,
