Yes that's what I meant to explain in the previous post.
I can see the communication from A16 -> expansion board (which I already knew), and with the USB adapter I can also see the communication from expansion board -> A16.
I know it is being sent by the expansion board, but the ESP32 does not receive it. I have shown in previous posts that I activated debug logging of the UART component and I can see the raw bytes leaving the UART TX (i.e. pin 13), and I can see that no bytes are being received on the UART RX (i.e. pin 16).
